+	<p>This specification describes the use
+	of HTTP for accessing, updating, creating and deleting resources from
+	servers that expose their resources as Linked Data.  It provides clarifications
+	and extensions of the rules of Linked Data [<cite><a class="bibref" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#bib-LINKED-DATA">LINKED-DATA</a></cite>]:</p>

+		<li>Use URIs as names for things</li>
+		<li>Use HTTP URIs so that people can look up those names</li>
+		<li>When someone looks up a URI, provide useful information, using the standards

+	</ol>
+	<p>This specification discusses standard HTTP and <abbr title="Resource Description Framework">RDF</abbr> techniques  
+	used when constructing clients and servers that 
+	create, read, and write <a title="Linked Data Platform Resource" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-linked-data-platform-resource" class="internalDFN">Linked Data Platform Resources</a>.
+	A companion document discusses best practices that you 
+	should use, and anti-patterns you should avoid, when constructing these clients and servers.
+	</p> 
+	<p>This specification defines a special type of <a href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-linked-data-platform-resource" class="internalDFN">Linked Data Platform Resource</a>: a 
+	<a title="Linked Data Platform Container" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-linked-data-platform-container" class="internalDFN">Container</a>.  Containers are very useful 
+	in building application models involving collections of resources, often homogeneous ones. 
+	For example, universities offer a collection of classes 
+	and have a collection of faculty members, each faculty member teaches a collection of courses, and so on. 
+	This specification discusses how to work with containers.  Resources can be added to containers  
+	using standard HTTP operations like 
+	POST (see <a href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#ldpc-HTTP_POST" class="sectionRef sec-ref">section <span class="secno">5.2.3</span> <span class="sec-title">HTTP POST</span></a>).</p>
+	<p>The intention of this specification is to enable additional rules and layered groupings of rules as 
+	additional specifications.  The scope is intentionally narrow to provide a set of key rules for 
+	reading and writing Linked Data that most, if not all, other specifications will depend upon and 
+	implementations will support.</p>
+	<p>This specification provides some approaches to deal with large resources.  An extension to this specification
+	provides the ability to break large resource representations into multiple paged responses [<cite><a class="bibref" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#bib-LDP-PAGING">LDP-PAGING</a></cite>].</p>

+	<p>The following sections define the conformance rules for LDP servers when serving <abbr title="Linked Data Platform Resources">LDPRs</abbr>.
+	Companion non-normative documents describe additional guidelines for use when interacting with <abbr title="Linked Data Platform Resources">LDPRs</abbr>. 
+	</p>
+	<p><abbr title="Linked Data Platform RDF Source">LDP-RS</abbr>'s representations may be too big, one strategy is to break up the response representation
+	into client consumable chunks called pages. A separate LDP specification outlines the conformance
+	rules around pagination [<cite><a class="bibref" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#bib-LDP-PAGING">LDP-PAGING</a></cite>].
+	</p>
+	<p>An LDP server manages two kinds of <a title="Linked Data Platform Resources" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-linked-data-platform-resources" class="internalDFN"><abbr title="Linked Data Platform Resources">LDPRs</abbr></a>, those resources who whose state 
+	is represented using <abbr title="Resource Description Framework">RDF</abbr> (<abbr title="Linked Data Platform RDF Source">LDP-RS</abbr>) and those using other formats (<abbr title="Linked Data Platform Non-RDF Source">LDP-NR</abbr>).  LDP-RSs have the unique
+	quality that their representation is based on <abbr title="Resource Description Framework">RDF</abbr>, which addresses a number of use cases from web metadata, open data 
+	models, machine processable information, and automated processing by software agents [<cite><a class="bibref" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#bib-rdf11-concepts">rdf11-concepts</a></cite>].  LDP-NRs are almost anything
+	on the Web today: images, HTML pages, word processing documents, spreadsheets, etc. and LDP-RSs hold 
+	metadata associated with LDP-NRs in some cases.

+	<p>Many HTTP applications and sites have organizing
+		concepts that partition the overall space of resources into smaller
+		containers. Blog posts are grouped into blogs, wiki pages are grouped
+		into wikis, and products are grouped into catalogs. Each resource
+		created in the application or site is created within an instance of
+		one of these container-like entities, and users can list the existing
+		artifacts within one. Containers answer some basic questions, which
+		are:</p>
+	<ol>
+		<li>To which URLs can I POST to create new resources?</li>
+		<li>Where can I GET a list of existing resources?</li>

+		This document defines the representation and behavior of containers
+		that address these issues. There are multiple types of containers defined
+		to support a variety of use cases, all that support a base set of capabilities.
+		The contents of a container is
+		defined by a set of triples in its representation (and state) called
+		the <a title="Containment triples" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-containment-triples" class="internalDFN">containment triples</a> that follow a fixed pattern.
+		Additional types of containers allow for the set of members of a container to be
+		defined by a set of triples in its representation called
+		the <a title="Membership triples" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-membership-triples" class="internalDFN">membership triples</a> that follow a consistent pattern
+		(see the linked-to definition for the possible patterns). 
+		The membership triples of a container all
+		have the same predicate, called the membership predicate, 
+		and either the subject or the object is also a consistent value
+		– the remaining position of the membership
+		triples (the one that varies) define the members of the container. 
+		In the simplest cases, the
+		consistent value will be the <abbr title="Linked Data Platform Container">LDPC</abbr> resource's URI, but it does not
+		have to be. The membership predicate is also variable and will often
+		be a predicate from the server application vocabulary or the <code>ldp:member</code> predicate.
+	</p>
+	<p>This document includes a set of guidelines for
+		creating new resources and adding them to the list of
+		resources linked to a container. It goes on to explain how to learn about a set of related
+		resources, regardless of how they were created or added to the container's membership.
+		It also defines behavior when resources created using a container are later deleted;
+		deleting containers removes membership information and
+		possibly performs some cleanup tasks on unreferenced member resources.</p>
+
+	<p>The following illustrates a very simple
+		container with only three members and some information about the
+		container (the fact that it is a container and a brief title):</p>

+    </figure>
+     -->
+
+	<p>This example is very straightforward - there is the containment triple
+	with subject of the container, predicate of  
+	<code>ldp:contains</code> and objects indicating the URIs of the contained resources. 
+	A POST to this container will create a new resource
+	and add it to the list of contained resources by adding a new containment triple
+	to the container.  This type of container is also referred to as
+	<a title="" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-linked-data-platform-basic-container" class="internalDFN">Linked Data Platform Basic Container</a>.</p>
+
+	<p>Sometimes it is useful to use a subject
+	other than the container itself as the consistent membership value, and/or to use
+	a  predicate from an application's domain model as the membership predicate. Let's
+	start with a domain resource for a person's net worth, as illustrated below:</p>
+			
+<div class="example"><div class="example-title"><span>Example 2</span></div><pre class="example" id="ldpc-ex-membership-partial"># The following is a partial representation of

+      &lt;liabilityContainer/l3&gt;.</pre></div>
+	<p>From this example, there is a <code>rdf:type</code> of <code>o:NetWorth</code> indicating the
+	resource represents an instance of a person's net worth and <code>o:netWorthOf</code> predicate indicating 
+	the associated person.  There are two sets of same-subject, same-predicate pairings; one for assets and
+	one for liabilities.  It would be helpful to be able to associate these multi-valued sets using a URL
+	for them to assist with managing these, this is done by associating containers with them as 
+	illustrated in the set of related examples (one example per HTTP resource) below:

+
+	<p>The essential structure of the container is
+	the same, but in this example, the consistent membership value 
+	(<a title="Membership triples" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-membership-triples" class="internalDFN">membership-constant-URI</a>, still in the subject position) is not the
+	container itself – it is a separate net worth resource. The
+	membership predicates are <code>o:asset</code> and <code>o:liability</code> – predicates
+	from the domain model. A POST of an asset representation to the asset container will create a new
+	asset and add it to the list of	members by adding a new membership triple
+	to the resource and containment triple to the container. You might wonder why
+	<code>http://example.org/netWorth/nw1</code> isn't made a container itself and POST
+	the new asset directly there. That would be a fine design if <code>http://example.org/netWorth/nw1</code>
+	had only assets, but if it has separate predicates for assets and liabilities,
+	that design will not work because it is unspecified to which predicate the POST
+	should add a membership triple. Having separate <code>http://example.org/netWorth/nw1/assetContainer/</code> 
+	and <code>http://example.org/netWorth/nw1/liabilityContainer/</code> container
+	resources allows both assets and liabilities to be created.
+	</p>
+	<p>This type of container is referred to as an <a title="Linked Data Platform Direct Container" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-linked-data-platform-direct-container" class="internalDFN">LDP Direct Container</a>.  
+	<a title="Linked Data Platform Direct Container" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-linked-data-platform-direct-container" class="internalDFN">LDP Direct Container</a> adds the concept of <a title="Membership" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-membership" class="internalDFN">membership</a>
+	and flexibilty on how to specify the <a title="Membership triples" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-membership-triples" class="internalDFN">membership triples</a>.
+	</p>
+
+	<p>As seen in the <a href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#ldpc-ex-membership-subj"><code>assetContainer/</code> example</a>, 
+	clients cannot correctly guess
+	at the membership triples, so the example includes this information in
+	triples whose subject is the <abbr title="Linked Data Platform Container">LDPC</abbr> resource itself.
+	</p>
+	
+	<p>Alternatively, servers may provide the net worth resource and supporting containers in a single response
+	representations.  When doing this, a preference would be for <abbr title="Resource Description Framework">RDF</abbr> formats that support multiple named graphs, one
+	named graph for the net worth resource and then two others for asset and liability containers.  This allows for
+	the membership triples to be represented with the named graph for the net worth resource, while the containment triples
+	would be represented within the liability and asset containers [<cite><a class="bibref" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#bib-rdf11-concepts">rdf11-concepts</a></cite>].  Generally, the membership triples belong
+	to the representation of an <abbr title="Linked Data Platform RDF Source">LDP-RS</abbr> and the containment triples belong to the representation of the <abbr title="Linked Data Platform Container">LDPC</abbr>.
+	</p>
+	
+	<p>Additionally, we could extend our net worth example to include a container for
+	advisors (people) that have managed the assets and liabilities.  We have decided
+	to identify these advisors with URLs that contain a fragment (hash) to represent
+	these real-world resources, not the documents that describe them.</p>

+	</h4><!-- Was 5.1.1 / #ldpc-get_empty-container_props -->
+	<p>The representation of a container
+		that has many members will be large. There are several important
+		cases where clients need to access only the subset of the container's properties 
+		that are unrelated to member resources and unrelated to contained documents, for
+		example to determine the membership triple pattern and membership predicate of an 
+		<abbr title="Linked Data Platform Direct Container">LDP-DC</abbr>.  LDP calls these <a title="Empty-container triples" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-empty-container-triples" class="internalDFN">empty-container triples</a>,
+		because they are what remains when the container has zero members and zero contained resources.
+		Since retrieving the whole container representation to
+		get this information may be onerous for clients and cause unnecessary
+		overhead on servers, we define a way to retrieve only
+		these property values (and more generally, a way to retrieve only the 
+		subset of properties used to address other major clusters of use cases).
+		LDP adds parameters to the HTTP <code>Prefer</code> header's 
+		<code>return=representation</code> preference for this 
+		(see <a href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#prefer-parameters" class="sectionRef sec-ref">section <span class="secno">7.2</span> <span class="sec-title">Preferences on the Prefer Request Header</span></a> for details).
+	</p>
+	<p>The example listed here only shows
+		a simple case where few empty-container triples are
+		retrieved. In real world situations more complex cases are likely, such as those that add other predicates to
+		containers, for example providing validation information and
+		associating <abbr title="SPARQL Protocol and RDF Query Language">SPARQL</abbr> endpoints. [<cite><a class="bibref" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#bib-sparql11-query">sparql11-query</a></cite>]</p>

+		<p>The LDP Working Group proposes incorporation of the features described in this section.</p>
+		<ul>
+		<li>The addition of <a>209 Related Content</a> in this specification is pending 
+		advancement of an <a href="https://datatracker.ietf.org/doc/draft-wilde-related-content/">IETF draft</a>
+		that would fully include it, patterned after the codes defined by [[RFC6585]].  Once LDP is in
+		Candidate Recommendation status, the LDP WG will make an assessment based on the status at IETF
+		working with the W3C Director.</li>
+		</ul>
+	</div>
+		
+	<p>The <code>209 Related Content</code> status code indicates that the origin server 
+		is supplying the representation of a different resource than the target resource,
+		and the origin server believes that the supplied representation 
+		is likely to satisfy the user agent's original request.
+		The resource whose representation is supplied is descriptive of the target resource, in
+		the same way that the <code>Location</code> header in a <code>303 See Other</code>
+		response is descriptive of the target resource.
+	</p>
+	<p><code>209 Related Content</code> is intended to be used in situations where 
+		<code>303 See Other</code> could have been used and would most likely result in a
+		user agent retrieving the other resource, but saves the user agent from
+		the latency penalty of having to perform a separate retrieval request.
+	</p>
+   
+	<p>	LDP uses <code>209 Related Content</code> to provide clients with the 
+		<a href="#ldpr-Paging">first page of a large resource</a>, but it can also be used in
+		other common situations.  Linked Data clients could benefit by avoiding the latency
+		of additional requests when the target resource is a concept resource (one without any
+		representation capable of transmission over HTTP), and general HTTP clients would
+		benefit in many of the more general cases where <code>303 See Other</code> responses

+security-related facilities associated with it and are not required to carry out LDP operations 
+that may be in contradistinction to a particular security policy in place. For example, when faced with an

+consider responding with the 401 status code (Unauthorized), indicating that the appropriate authorization 
+is required. In cases where authentication is provided fails to meet the requirements of a particular access control 
+policy, the 403 status code (Forbidden) can be sent back to the client to indicate this failure to meet the
+access control policy.</p>

-	<p>This specification describes the use
-	of HTTP for accessing, updating, creating and deleting resources from
-	servers that expose their resources as Linked Data.  It provides clarifications
-	and extensions of the rules of Linked Data [<cite><a class="bibref" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#bib-LINKED-DATA">LINKED-DATA</a></cite>]:</p>
-	<ol>
-		<li>Use URIs as names for things</li>
-		<li>Use HTTP URIs so that people can look up those names</li>
-		<li>When someone looks up a URI, provide useful information, using the standards
-			(<abbr title="Resource Description Framework">RDF</abbr>*, <abbr title="SPARQL Protocol and RDF Query Language">SPARQL</abbr>)
-		</li>
-		<li>Include links to other URIs, so that they can discover more things</li>
-	</ol>
-	<p>This specification discusses standard HTTP and <abbr title="Resource Description Framework">RDF</abbr> techniques  
-	used when constructing clients and servers that 
-	create, read, and write <a title="Linked Data Platform Resource" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-linked-data-platform-resource" class="internalDFN">Linked Data Platform Resources</a>.
-	A companion document discusses best practices that you 
-	should use, and anti-patterns you should avoid, when constructing these clients and servers.
-	</p> 
-	<p>This specification defines a special type of <a href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-linked-data-platform-resource" class="internalDFN">Linked Data Platform Resource</a>: a 
-	<a title="Linked Data Platform Container" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-linked-data-platform-container" class="internalDFN">Container</a>.  Containers are very useful 
-	in building application models involving collections of resources, often homogeneous ones. 
-	For example, universities offer a collection of classes 
-	and have a collection of faculty members, each faculty member teaches a collection of courses, and so on. 
-	This specification discusses how to work with containers.  Resources can be added to containers  
-	using standard HTTP operations like 
-	POST (see <a href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#ldpc-HTTP_POST" class="sectionRef sec-ref">section <span class="secno">5.2.3</span> <span class="sec-title">HTTP POST</span></a>).</p>
-	<p>The intention of this specification is to enable additional rules and layered groupings of rules as 
-	additional specifications.  The scope is intentionally narrow to provide a set of key rules for 
-	reading and writing Linked Data that most, if not all, other specifications will depend upon and 
-	implementations will support.</p>
-	<p>This specification provides some approaches to deal with large resources.  An extension to this specification
-	provides the ability to break large resource representations into multiple paged responses [<cite><a class="bibref" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#bib-LDP-PAGING">LDP-PAGING</a></cite>].</p>

-	<p>Linked Data Platform Resources (<dfn id="dfn-linked-data-platform-resources"><abbr title="Linked Data Platform Resources">LDPRs</abbr></dfn>) are HTTP resources
-		that conform to the simple patterns and conventions in this section.
-		HTTP requests to access, modify, create or delete <abbr title="Linked Data Platform Resources">LDPRs</abbr> are accepted
-		and processed by <a title="LDP server" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-ldp-server" class="internalDFN">LDP servers</a>. Most <abbr title="Linked Data Platform Resources">LDPRs</abbr> are domain-specific resources
-		that contain data for an entity in some domain, which could be
-		commercial, governmental, scientific, religious, or other.</p>
-	<p>Some of the rules defined in this document provide
-		clarification and refinement of the base Linked Data rules [<cite><a class="bibref" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#bib-LINKED-DATA">LINKED-DATA</a></cite>];
-		others address additional needs.</p>
-	<p>The rules for Linked Data Platform Resources address basic
-		questions such as:</p>
-	<ul>
-		<li>What resource representations should be used?</li>
-		<li>How is optimistic collision detection handled for updates?</li>
-		<li>What should client expectations be for changes to linked-to resources,
-				such as type changes?</li>
-		<li>What can servers do to ease the burden of constraints for resource
-				creation?</li>
-		<li>How	do I GET the representation of a large resource broken up into pages?</li>
-	</ul>
-	<p>Additional non-normative guidance is available in the <a href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp-bp/ldp-bp.html" class="external" title="LDP Best Practices and Guidelines" rel="nofollow">LDP Best Practices and Guidelines editor's draft</a> that addresses
-		questions such as:</p>
-	<ul>
-		<li>What literal value types should be used?</li>
-		<li>Are there some typical vocabularies that should be reused?</li>
-	</ul>
-	<p>The following sections define the conformance rules for LDP servers when serving <abbr title="Linked Data Platform Resources">LDPRs</abbr>.
-	Companion non-normative documents describe additional guidelines for use when interacting with <abbr title="Linked Data Platform Resources">LDPRs</abbr>. 
-	</p>
-	<p><abbr title="Linked Data Platform RDF Source">LDP-RS</abbr>'s representations may be too big, one strategy is to break up the response representation
-	into client consumable chunks called pages. A separate LDP specification outlines the conformance
-	rules around pagination [<cite><a class="bibref" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#bib-LDP-PAGING">LDP-PAGING</a></cite>].
-	</p>
-	<p>An LDP server manages two kinds of <a title="Linked Data Platform Resources" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-linked-data-platform-resources" class="internalDFN"><abbr title="Linked Data Platform Resources">LDPRs</abbr></a>, those resources who whose state 
-	is represented using <abbr title="Resource Description Framework">RDF</abbr> (<abbr title="Linked Data Platform RDF Source">LDP-RS</abbr>) and those using other formats (<abbr title="Linked Data Platform Non-RDF Source">LDP-NR</abbr>).  LDP-RSs have the unique
-	quality that their representation is based on <abbr title="Resource Description Framework">RDF</abbr>, which addresses a number of use cases from web metadata, open data 
-	models, machine processable information, and automated processing by software agents [<cite><a class="bibref" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#bib-rdf11-concepts">rdf11-concepts</a></cite>].  LDP-NRs are almost anything
-	on the Web today: images, HTML pages, word processing documents, spreadsheets, etc. and LDP-RSs hold 
-	metadata associated with LDP-NRs in some cases.

-		This is <strong>not</strong> equivalent to the
-		presence of a <var>(subject-URI, <code>rdf:type</code>, <code>ldp:Resource</code>)</var> triple in an <abbr title="Linked Data Platform RDF Source">LDP-RS</abbr>.
-		The presence of this header asserts that the server complies with the LDP specification's constraints on

-	<p>Many HTTP applications and sites have organizing
-		concepts that partition the overall space of resources into smaller
-		containers. Blog posts are grouped into blogs, wiki pages are grouped
-		into wikis, and products are grouped into catalogs. Each resource
-		created in the application or site is created within an instance of
-		one of these container-like entities, and users can list the existing
-		artifacts within one. Containers answer some basic questions, which
-		are:</p>
-	<ol>
-		<li>To which URLs can I POST to create new resources?</li>
-		<li>Where can I GET a list of existing resources?</li>
-		<li>How do I get information about the members along with the container?</li>
-		<li>How	can I ensure the resource data is easy to query?</li>
-		<li>How	is the order of the container entries expressed? [<cite><a class="bibref" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#bib-LDP-PAGING">LDP-PAGING</a></cite>]</li>
-	</ol>
-	<p>
-		This document defines the representation and behavior of containers
-		that address these issues. There are multiple types of containers defined
-		to support a variety of use cases, all that support a base set of capabilities.
-		The contents of a container is
-		defined by a set of triples in its representation (and state) called
-		the <a title="Containment triples" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-containment-triples" class="internalDFN">containment triples</a> that follow a fixed pattern.
-		Additional types of containers allow for the set of members of a container to be
-		defined by a set of triples in its representation called
-		the <a title="Membership triples" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-membership-triples" class="internalDFN">membership triples</a> that follow a consistent pattern
-		(see the linked-to definition for the possible patterns). 
-		The membership triples of a container all
-		have the same predicate, called the membership predicate, 
-		and either the subject or the object is also a consistent value
-		– the remaining position of the membership
-		triples (the one that varies) define the members of the container. 
-		In the simplest cases, the
-		consistent value will be the <abbr title="Linked Data Platform Container">LDPC</abbr> resource's URI, but it does not
-		have to be. The membership predicate is also variable and will often
-		be a predicate from the server application vocabulary or the <code>ldp:member</code> predicate.
-	</p>
-	<p>This document includes a set of guidelines for
-		creating new resources and adding them to the list of
-		resources linked to a container. It goes on to explain how to learn about a set of related
-		resources, regardless of how they were created or added to the container's membership.
-		It also defines behavior when resources created using a container are later deleted;
-		deleting containers removes membership information and
-		possibly performs some cleanup tasks on unreferenced member resources.</p>
-
-	<p>The following illustrates a very simple
-		container with only three members and some information about the
-		container (the fact that it is a container and a brief title):</p>
-
-<div class="example"><div class="example-title"><span>Example 1</span></div><pre class="example" id="ldpc-ex-simple"># The following is the representation of

-    </figure>
-     -->
-
-	<p>This example is very straightforward - there is the containment triple
-	with subject of the container, predicate of  
-	<code>ldp:contains</code> and objects indicating the URIs of the contained resources. 
-	A POST to this container will create a new resource
-	and add it to the list of contained resources by adding a new containment triple
-	to the container.  This type of container is also referred to as
-	<a title="" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-linked-data-platform-basic-container" class="internalDFN">Linked Data Platform Basic Container</a>.</p>
-
-	<p>Sometimes it is useful to use a subject
-	other than the container itself as the consistent membership value, and/or to use
-	a  predicate from an application's domain model as the membership predicate. Let's
-	start with a domain resource for a person's net worth, as illustrated below:</p>
-			
-<div class="example"><div class="example-title"><span>Example 2</span></div><pre class="example" id="ldpc-ex-membership-partial"># The following is a partial representation of
-#   http://example.org/netWorth/nw1

-      &lt;liabilityContainer/l1&gt;,
-      &lt;liabilityContainer/l2&gt;,
-      &lt;liabilityContainer/l3&gt;.</pre></div>
-	<p>From this example, there is a <code>rdf:type</code> of <code>o:NetWorth</code> indicating the
-	resource represents an instance of a person's net worth and <code>o:netWorthOf</code> predicate indicating 
-	the associated person.  There are two sets of same-subject, same-predicate pairings; one for assets and
-	one for liabilities.  It would be helpful to be able to associate these multi-valued sets using a URL
-	for them to assist with managing these, this is done by associating containers with them as 
-	illustrated in the set of related examples (one example per HTTP resource) below:

-
-	<p>The essential structure of the container is
-	the same, but in this example, the consistent membership value 
-	(<a title="Membership triples" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-membership-triples" class="internalDFN">membership-constant-URI</a>, still in the subject position) is not the
-	container itself – it is a separate net worth resource. The
-	membership predicates are <code>o:asset</code> and <code>o:liability</code> – predicates
-	from the domain model. A POST of an asset representation to the asset container will create a new
-	asset and add it to the list of	members by adding a new membership triple
-	to the resource and containment triple to the container. You might wonder why
-	<code>http://example.org/netWorth/nw1</code> isn't made a container itself and POST
-	the new asset directly there. That would be a fine design if <code>http://example.org/netWorth/nw1</code>
-	had only assets, but if it has separate predicates for assets and liabilities,
-	that design will not work because it is unspecified to which predicate the POST
-	should add a membership triple. Having separate <code>http://example.org/netWorth/nw1/assetContainer/</code> 
-	and <code>http://example.org/netWorth/nw1/liabilityContainer/</code> container
-	resources allows both assets and liabilities to be created.
-	</p>
-	<p>This type of container is referred to as an <a title="Linked Data Platform Direct Container" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-linked-data-platform-direct-container" class="internalDFN">LDP Direct Container</a>.

-	and flexibilty on how to specify the <a title="Membership triples" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-membership-triples" class="internalDFN">membership triples</a>.
-	</p>
-
-	<p>As seen in the <a href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#ldpc-ex-membership-subj"><code>assetContainer/</code> example</a>, 
-	clients cannot correctly guess
-	at the membership triples, so the example includes this information in
-	triples whose subject is the <abbr title="Linked Data Platform Container">LDPC</abbr> resource itself.
-	</p>
-	
-	<p>Alternatively, servers may provide the net worth resource and supporting containers in a single response
-	representations.  When doing this, a preference would be for <abbr title="Resource Description Framework">RDF</abbr> formats that support multiple named graphs, one
-	named graph for the net worth resource and then two others for asset and liability containers.  This allows for
-	the membership triples to be represented with the named graph for the net worth resource, while the containment triples
-	would be represented within the liability and asset containers [<cite><a class="bibref" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#bib-rdf11-concepts">rdf11-concepts</a></cite>].  Generally, the membership triples belong
-	to the representation of an <abbr title="Linked Data Platform RDF Source">LDP-RS</abbr> and the containment triples belong to the representation of the <abbr title="Linked Data Platform Container">LDPC</abbr>.
-	</p>
-	
-	<p>Additionally, we could extend our net worth example to include a container for
-	advisors (people) that have managed the assets and liabilities.  We have decided
-	to identify these advisors with URLs that contain a fragment (hash) to represent
-	these real-world resources, not the documents that describe them.</p>

-	</h4><!-- Was 5.1.1 / #ldpc-get_empty-container_props -->
-	<p>The representation of a container
-		that has many members will be large. There are several important
-		cases where clients need to access only the subset of the container's properties 
-		that are unrelated to member resources and unrelated to contained documents, for
-		example to determine the membership triple pattern and membership predicate of an 
-		<abbr title="Linked Data Platform Direct Container">LDP-DC</abbr>.  LDP calls these <a title="Empty-container triples" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#dfn-empty-container-triples" class="internalDFN">empty-container triples</a>,
-		because they are what remains when the container has zero members and zero contained resources.
-		Since retrieving the whole container representation to
-		get this information may be onerous for clients and cause unnecessary
-		overhead on servers, we define a way to retrieve only
-		these property values (and more generally, a way to retrieve only the 
-		subset of properties used to address other major clusters of use cases).
-		LDP adds parameters to the HTTP <code>Prefer</code> header's 
-		<code>return=representation</code> preference for this 
-		(see <a href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#prefer-parameters" class="sectionRef sec-ref">section <span class="secno">7.2</span> <span class="sec-title">Preferences on the Prefer Request Header</span></a> for details).
-	</p>
-	<p>The example listed here only shows
-		a simple case where few empty-container triples are
-		retrieved. In real world situations more complex cases are likely, such as those that add other predicates to
-		containers, for example providing validation information and
-		associating <abbr title="SPARQL Protocol and RDF Query Language">SPARQL</abbr> endpoints. [<cite><a class="bibref" href="https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#bib-sparql11-query">sparql11-query</a></cite>]</p>

-	client application is interested in and, if received, is likely to be 
-	processed.  LDP Containers with large numbers of associated documents

-
-	<div class="atrisk"><p class="atrisktext">Feature At Risk</p>
-		<p>The LDP Working Group proposes incorporation of the features described in this section.</p>
-		<ul>
-		<li>The addition of <a>209 Related Content</a> in this specification is pending 
-		advancement of an <a href="https://datatracker.ietf.org/doc/draft-wilde-related-content/">IETF draft</a>
-		that would fully include it, patterned after the codes defined by [[RFC6585]].  Once LDP is in
-		Candidate Recommendation status, the LDP WG will make an assessment based on the status at IETF
-		working with the W3C Director.</li>
-		</ul>
-	</div>
-		
-	<p>The <code>209 Related Content</code> status code indicates that the origin server 
-		is supplying the representation of a different resource than the target resource,
-		and the origin server believes that the supplied representation 
-		is likely to satisfy the user agent's original request.
-		The resource whose representation is supplied is descriptive of the target resource, in
-		the same way that the <code>Location</code> header in a <code>303 See Other</code>
-		response is descriptive of the target resource.
-	</p>
-	<p><code>209 Related Content</code> is intended to be used in situations where 
-		<code>303 See Other</code> could have been used and would most likely result in a
-		user agent retrieving the other resource, but saves the user agent from
-		the latency penalty of having to perform a separate retrieval request.
-	</p>
-   
-	<p>	LDP uses <code>209 Related Content</code> to provide clients with the 
-		<a href="#ldpr-Paging">first page of a large resource</a>, but it can also be used in
-		other common situations.  Linked Data clients could benefit by avoiding the latency
-		of additional requests when the target resource is a concept resource (one without any
-		representation capable of transmission over HTTP), and general HTTP clients would
-		benefit in many of the more general cases where <code>303 See Other</code> responses
-		are currently used.

-security-related facilities associated with it and are not required to carry out LDP operations 
-that may be in contradistinction to a particular security policy in place. For example, when faced with an 
-unauthenticated request to replace system critical <abbr title="Resource Description Framework">RDF</abbr> statements in a graph through the PUT method, applications may
-consider responding with the 401 status code (Unauthorized), indicating that the appropriate authorization 
-is required. In cases where authentication is provided fails to meet the requirements of a particular access control 
-policy, the 403 status code (Forbidden) can be sent back to the client to indicate this failure to meet the
-access control policy.</p>
