-<p>
-Provenance is information about entities, activities, and people
-involved in producing a piece of data or thing, which can be used to
-form assessments about its quality, reliability or
-trustworthiness. PROV-DM is the conceptual data model that forms a
-basis for the <abbr title="World Wide Web Consortium">W3C</abbr> provenance (PROV) family of specifications.
-</p>
-
-
-<p> This document presents a model-theoretic semantics for the PROV
-data model (called the <dfn id="dfn-reference-semantics">reference semantics</dfn>), viewing
-PROV-DM statements as atomic formulas in the sense of first-order
-logic, and viewing the constraints and inferences specified in
-PROV-CONSTRAINTS as a first-order theory. It is shown that the
-first-order theory is sound with respect to the reference semantics.
-This information may be useful to researchers or users of PROV to
-understand the intended meaning and use of PROV for modeling
-information about the actual history, derivation or evolution of Web
-resources.  It may also be useful for development of additional
-constraints or inferences for reasoning about PROV or integration of
-PROV with other Semantic Web vocabularies.  It is <b>not</b> proposed
-as a canonical or required semantics of PROV and does not place any
-constraints on use of PROV.</p>
-
-<p>The PROV Document Overview describes the overall state of PROV, and should be read before other PROV documents.</p>

-<p>The PROV-DM and PROV-CONSTRAINTS give motivating examples that
-provide an intuition about the meaning of the constructs.  For some
-concepts, such as use, start, end, generation/invalidation, and
-derivation, the meaning is either obvious or situation-dependent.
-However, during the development of PROV, the importance of additional
-concepts became evident, but the intuitive meaning or correct use of
-these concepts were not clear.  For example, the <span class="MathJax_Preview"></span><span style="" aria-readonly="true" role="textbox" id="MathJax-Element-1-Frame" class="MathJax"><nobr><span id="MathJax-Span-1" class="math"><span style="display: inline-block; position: relative; width: 83px; height: 0px; font-size: 107%;"><span style="position: absolute; clip: rect(1.712em, 1000em, 2.952em, -0.509em); top: -2.57em; left: 0em;"><span id="MathJax-Span-2" class="mrow"><span style="font-family: STIXGeneral; font-style: italic;" id="MathJax-Span-3" class="mi">a</span><span style="font-family: STIXGeneral; font-style: italic;" id="MathJax-Span-4" class="mi">l<span style="display: inline-block; overflow: hidden; height: 1px; width: 0.001em;"></span></span><span style="font-family: STIXGeneral; font-style: italic;" id="MathJax-Span-5" class="mi">t<span style="display: inline-block; overflow: hidden; height: 1px; width: 0.018em;"></span></span><span style="font-family: STIXGeneral; font-style: italic;" id="MathJax-Span-6" class="mi">e</span><span style="font-family: STIXGeneral; font-style: italic;" id="MathJax-Span-7" class="mi">r<span style="display: inline-block; overflow: hidden; height: 1px; width: 0.023em;"></span></span><span style="font-family: STIXGeneral; font-style: italic;" id="MathJax-Span-8" class="mi">n</span><span style="font-family: STIXGeneral; font-style: italic;" id="MathJax-Span-9" class="mi">a</span><span style="font-family: STIXGeneral; font-style: italic;" id="MathJax-Span-10" class="mi">t<span style="display: inline-block; overflow: hidden; height: 1px; width: 0.018em;"></span></span><span style="font-family: STIXGeneral; font-style: italic;" id="MathJax-Span-11" class="mi">e</span><span style="font-family: STIXGeneral; font-style: italic;" id="MathJax-Span-12" class="mi">O</span><span style="font-family: STIXGeneral; font-style: italic;" id="MathJax-Span-13" class="mi">f<span style="display: inline-block; overflow: hidden; height: 1px; width: 0.146em;"></span></span></span><span style="display: inline-block; width: 0px; height: 2.57em;"></span></span></span><span style="border-left: 0em solid; display: inline-block; overflow: hidden; width: 0px; height: 1.077em; vertical-align: -0.284em;"></span></span></nobr></span><script id="MathJax-Element-1" type="math/tex">alternateOf</script> and

-entities that present aspects of "the same thing".  
-Over time the working group came to a

-PROV documents; instead, some of their properties are captured

-not captured in PROV specifications at all.
-</p>
-
-<p>The purpose of this document is to present the working group's
-consensus view of the semantics of PROV, using tools from mathematical
-logic, principally model theory (though our use of these tools is lightweight).  This information may be useful to users for understanding the
-intent behind certain features of PROV, to researchers investigating
-richer forms of reasoning over provenance, or to future efforts
-building upon PROV.  It is intended as an exploration of a <b>reference</b>
-semantics for PROV, not a definitive specification of the  <b>only</b>
-semantics of PROV.  </p>
-
-<p> Nevertheless, the reference semantics does have appealing
-properties.  Specifically, it provides a declarative counterpart to
-the operational definition of validity taken in PROV-CONSTRAINTS.  In
-the specification, validity is defined via a normalization process
-followed by constraint checking on the normal form.  This approach was adopted
-to keep the specification closer to implementations, although other
-implementations are possible and allowed.  In addition to providing a
-reference semantics, this document shows that the operational
-presentation of PROV validity checking is sound with respect to
-declarative presentation adopted here.  This could help justify
-alternative approaches to validity checking.</p>

-<h2> Overview </h2>
-
-
-<p>The idea of this document is to sketch what aspects of the provenance model can be formalized and how they can be formalized, as a first step towards establishing a consensus on the (intended) meaning of the components of the model and the consistency constraints or inferences that can be applied to the model to distinguish valid from invalid provenance records.</p>
-
-<p>The <a href="http://www.w3.org/TR/prov-constraints/">PROV-CONSTRAINTS</a> document contains formal content specifying a notion of validity (approximately, logical consistency) for PROV documents.  The formal semantics, PROV-SEM, is planned for release as a W3C Note that will complement the procedural specification in PROV-CONSTRAINTS with a declarative specification formulated in terms of first-order logic.   The formal semantics is <b>work in progress</b>.  The drafts below are intermediate stages and some of them are out of date.  
-</p>
-
-<h3> Status </h3>
-
-<p>
-This is work in progress.  The semantics is being updated to be consistent with the Candidate Recommendation of PROV.  The plan is to release the semantics as a Note over the next few months.  At that point, the wiki pages containing drafts of the semantics will be superseded.
-</p>
-
-
-<h3> Idea of the semantics </h3>
-
-<p>As a starting point, I will assume that we intend the statements made in a PROV-DM instance to be intended to describe one, consistent state of the world, much like a logical formula is said to be satisfied in a mathematical model.  That is, I propose an approach similar to that taken in model theory, where the PROV-DM instance corresponds to a formula or theory of a logic, and the semantics corresponds to what logicians call a model.</p>
-
-<p>For example, the formula $\forall x. P(x) \Rightarrow Q(x)$ is satisfied in a mathematical model where the relation $P$ denotes a set of elements that is contained in that denoted by $Q$.  Here, the goal is to come up with a plausible "intended model" for interpreting PROV-DM instances, where the formulas are statements in PROV-DM and the individuals are things and agents.  This is complicated by the fact that many statements about provenance involve talking about objects that change over time.</p>
-
-<p>The word "world" is used in PROV-DM to talk about the actual state
-of affairs that the PROV-DM instance describes, which is what I would
-usually call a "model".  The word "model" is used in PROV-DM mainly in
-the sense of "data model", that is, to talk about what I would
-otherwise call the syntax of PROV-DM.  To avoid confusion with the
-uses of terms in PROV-DM, I will use "structure" to describe the
-mathematical structure that corresponds to actual state of affairs.
-We use the term "model" to describe a structure that satisfies a given
-theory; this sense of "model" does not mean "data model".</p>
-
-<h3> Axiomatization and relationship to PROV-CONSTRAINTS </h3>
-
-<p>One goal of the semantics is to link the procedural specification of validity and equivalence with traditional notions of logical consistency and equivalence of theories, for example in first-order logic.  A first-order axiomatization that corresponds to the formal constraints and is sound for reasoning about the models described below is in progress at the end of the document.

-<h3>Instances as Theories</h3>
-<p>A PROV-DM
-instance can be viewed as a set of atomic formulas
-$\phi_1$...$\phi_n$, often called a <em>theory</em>.  A theory is
-viewed as a conjunction, that is, the overall instance is considered
-to hold in a given structure if each atomic formula in it holds.</p>

-
-    <p>
-    In this section we restate all of the inferences and constraints
-    of PROV-CONSTRAINTS in terms of first-order logic.  For each, we
-    give a proof sketch showing why the inference or constraint is
-    sound for reasoning about the reference semantics.  We exclude the
-    definitional rules in PROV-CONSTRAINTS because they are only
-    needed for expanding the abbreviated forms of PROV-N statements to
-    the logical formulas used here.</p>

+

+
+By "identity" I mean an element of the set of things.  This passage was confusing and I changed it to clarify what I am trying to say: basically, two different things  can be indistinguishable in terms of their attributes and lifespan withoug being identical.
+

+
+It is not necessary anywhere, but I think it is less confusing to keep the two sets separate (and this doesn't stop us from doing anything as far as I can see).  Otherwise, say x in Object intersect Thing, then could it have different lifespans according to whether we consider it an object or a thing?

+
+See also response to Luc.  This is a modeling choice, not a derived property, but note that you can have multiple derivation relations (with different identifiers) linking two entities.  So there is no loss of generality in supposing that each has its own path. 
+

Might the amount of text obscure the parts that are most interesting and not necessarily intuitive, e.g. in the definitions of precise derivation (single step derivation path), specialization and alternate (common things between entities)? Could these special features of the semantics be highlighted in some way?
+ > 
+
+This is a good point; a lot of the semantics is just restating the constraints in a different notation, as can often be the case with semantics.  The derivation paths and Thing/Entity/thingOf structure is more interesting and should be highlighted.  I'd ideally like to avoid saying the same thing several different ways but not sure yet how best to do this.

+<p>
+Provenance is information about entities, activities, and people
+involved in producing a piece of data or thing, which can be used to
+form assessments about its quality, reliability or
+trustworthiness. PROV-DM is the conceptual data model that forms a
+basis for the <abbr title="World Wide Web Consortium">W3C</abbr> provenance (PROV) family of specifications.
+</p>
+
+
+<p> This document presents a model-theoretic semantics for the PROV
+data model (called the <dfn id="dfn-reference-semantics">reference semantics</dfn>), viewing
+PROV-DM statements as atomic formulas in the sense of first-order
+logic, and viewing the constraints and inferences specified in
+PROV-CONSTRAINTS as a first-order theory. It is shown that the
+first-order theory is sound with respect to the reference semantics.
+This information may be useful to researchers or users of PROV to
+understand the intended meaning and use of PROV for modeling
+information about the actual history, derivation or evolution of Web
+resources.  It may also be useful for development of additional
+constraints or inferences for reasoning about PROV or integration of
+PROV with other Semantic Web vocabularies.  It is <b>not</b> proposed
+as a canonical or required semantics of PROV and does not place any
+constraints on use of PROV.</p>
+
+<p>The PROV Document Overview describes the overall state of PROV, and should be read before other PROV documents.</p>

+followed by constraint checking on the normal form.  This approach was adopted
+to keep the specification closer to implementations, although other
+implementations are possible and allowed.  In addition to providing a
+reference semantics, this document shows that the operational
+presentation of PROV validity checking is sound with respect to
+declarative presentation adopted here.  This could help justify
+alternative approaches to validity checking.</p>

+<h2> Overview </h2>
+
+
+<p>The idea of this document is to sketch what aspects of the provenance model can be formalized and how they can be formalized, as a first step towards establishing a consensus on the (intended) meaning of the components of the model and the consistency constraints or inferences that can be applied to the model to distinguish valid from invalid provenance records.</p>
+
+<p>The <a href="http://www.w3.org/TR/prov-constraints/">PROV-CONSTRAINTS</a> document contains formal content specifying a notion of validity (approximately, logical consistency) for PROV documents.  The formal semantics, PROV-SEM, is planned for release as a W3C Note that will complement the procedural specification in PROV-CONSTRAINTS with a declarative specification formulated in terms of first-order logic.   The formal semantics is <b>work in progress</b>.  The drafts below are intermediate stages and some of them are out of date.  
+</p>
+
+<h3> Status </h3>
+
+<p>
+This is work in progress.  The semantics is being updated to be consistent with the Candidate Recommendation of PROV.  The plan is to release the semantics as a Note over the next few months.  At that point, the wiki pages containing drafts of the semantics will be superseded.
+</p>
+
+
+<h3> Idea of the semantics </h3>
+
+<p>As a starting point, I will assume that we intend the statements made in a PROV-DM instance to be intended to describe one, consistent state of the world, much like a logical formula is said to be satisfied in a mathematical model.  That is, I propose an approach similar to that taken in model theory, where the PROV-DM instance corresponds to a formula or theory of a logic, and the semantics corresponds to what logicians call a model.</p>
+
+<p>For example, the formula $\forall x. P(x) \Rightarrow Q(x)$ is satisfied in a mathematical model where the relation $P$ denotes a set of elements that is contained in that denoted by $Q$.  Here, the goal is to come up with a plausible "intended model" for interpreting PROV-DM instances, where the formulas are statements in PROV-DM and the individuals are things and agents.  This is complicated by the fact that many statements about provenance involve talking about objects that change over time.</p>
+
+<p>The word "world" is used in PROV-DM to talk about the actual state
+of affairs that the PROV-DM instance describes, which is what I would
+usually call a "model".  The word "model" is used in PROV-DM mainly in
+the sense of "data model", that is, to talk about what I would
+otherwise call the syntax of PROV-DM.  To avoid confusion with the
+uses of terms in PROV-DM, I will use "structure" to describe the
+mathematical structure that corresponds to actual state of affairs.
+We use the term "model" to describe a structure that satisfies a given
+theory; this sense of "model" does not mean "data model".</p>
+
+<h3> Axiomatization and relationship to PROV-CONSTRAINTS </h3>
+
+<p>One goal of the semantics is to link the procedural specification of validity and equivalence with traditional notions of logical consistency and equivalence of theories, for example in first-order logic.  A first-order axiomatization that corresponds to the formal constraints and is sound for reasoning about the models described below is in progress at the end of the document.

+
+    <p>
+    In this section we restate all of the inferences and constraints
+    of PROV-CONSTRAINTS in terms of first-order logic.  For each, we
+    give a proof sketch showing why the inference or constraint is
+    sound for reasoning about the reference semantics.  We exclude the
+    definitional rules in PROV-CONSTRAINTS because they are only
+    needed for expanding the abbreviated forms of PROV-N statements to
+    the logical formulas used here.</p>
