    <h3>Alternate Entities and Specialization</h3>
    <p>
+    There is often more than one way to describe something in a record of
+    provenance. Each perspective will be referred to by a separately identified
+    entity, and PROV provides a mechanism for linking the different descriptions of
+    the same thing together through the mechanism of <i>specialization</i>. One
+    entity is a specialization of another entity if it shares the same fixed attributes,
+    with the possible addition of further fixed attributes. This concept is best
+    illustrated through a few use cases, as below.
+   </p>
+   <p>
+    Entities can be mutable things. For example, a webpage is a single
+    entity, W, despite being edited over time. Each version of the webpage is
+    also an entity, W1, W2... To connect an individual version to the webpage
+    in general, we say that the former is a specialization of the latter: W1 is a
+    specialization of W, W2 is a specialization of W, and so on.
+   </p>
+   <p>
+    Two individuals may create provenance referring to the same thing from different
+    perspectives. For example, the author of an article may attribute that article
+    to themselves using PROV while, independently, a reader might quote a fact from that
+    article elsewhere and document this in PROV. If the author later changes the fact,
+    then from the reader's perspective there are now two versions of the article, and
+    they had quoted from the version before the change. From the author's perspective,
+    there is a single article, attributed to themselves. If either of them, or a
+    third party, were to connect the two PROV records, they would say that the
+    article as referred to by the reader is a specialization of the same article
+    as referred to by the author.
+   </p>
+   <p>
+    If a file, F, is copied from one directory to another, we may want to say that
+    these are both the same file, just in a different location. We may say that
+    the file in the first directory, F1, is a specialization of F, and that the
+    file in the second directory, F2, is a specialization of F. Note that it is
+    the context (location) rather than content of the file that changes in this case.
+   </p>
+   <p>
+    The above are just some examples of where we may want to connect entities by
+    saying that they refer to the same thing, but at different levels of specialization.
+    PROV also allows us to more generally draw a connection between two descriptions
+    of the same thing, even if not at different levels of specialization. For example,
+    two versions of the webpage above, W1 and W2, are alternates of each other because
+    they describe the same webpage.
+   </p>

+   <h3>Alternate Entities and Specialization</h3>
+   <p>
     Entities are defined in a flexible way in PROV, allowing for different
     perspectives to be taken as appropriate for the application. The following
     are examples illustrating this idea.
