   JSON-LD data model encapsulates the following concepts:</p>
 
 <ol>
-  <li>The <tdef>JSON-LD data model</tdef> is used to represent <tref title="JSON-LD graph">JSON-LD graphs</tref>.</li>
-  <li>A <tdef>JSON-LD graph</tdef> is an unordered labeled directed graph, where each <tdef>node</tdef> is a <tref>subject</tref> or <tref>object</tref>, and edges are labeled using <tref title="property">properties</tref>.</li>
-  <li>A <tdef>subject</tdef> is any node in a <tref>JSON-LD graph</tref> with at least one outgoing edge.</li>
-  <li>A <tref>subject</tref> SHOULD be labeled with an <tref><abbr title="Internationalized Resource Identifier">IRI</abbr></tref> (an Internationalized Resource Identifier as described in [[!RFC3987]]).</li>
-  <li>An <tdef>object</tdef> is a node in a <tref>JSON-LD graph</tref> with at least one incoming edge.</li>
-  <li>An <tref>object</tref> MAY be labeled with an <tref>IRI</tref> or a label that is not an <tref>IRI</tref> such as plain text, internationalized text, or a strictly-typed data value.</li>
-  <li>A <tref>node</tref> MAY be a <tref>subject</tref> and an <tref>object</tref> at the same time.</li>
-  <li>A <tdef>property</tdef> is the label on an edge in a <tref>JSON-LD graph</tref>.</li>
-  <li>A <tref>property</tref> SHOULD be an <tref>IRI</tref>.</li>
-  <li>An <tref>IRI</tref> that is a label in a <tref>JSON-LD graph</tref> SHOULD be dereferencable to a <tref>Linked Data</tref> document describing the labeled <tref>subject</tref>, <tref>property</tref> or <tref>object</tref>.</li>

+  <li>A node having an outgoing edge must be an <tref>IRI</tref> or

 <p>There are a number of best practices that can ensure that developers
-will generate good Linked Data for the Web. JSON-LD
-formalizes those techniques by providing a mechanism to map JSON data,
-i.e., keys and values, to <tref>IRI</tref>s. This does not mean
-that JSON-LD requires every key or value to be an IRI, but rather ensures that
-keys and values can be mapped to IRIs if the developer desires to transform
-their data into <tref>Linked Data</tref>.
