I would really like to see it in Turtle as well - but perhaps there
are specification issues with using Turtle (a Team Submission at the
time of writing) in a normative document.

I would like to see the PROV primer to use Turtle and the abstract
syntax side by side - using RDF/XML here would probably make it
slightly harder to compare, although it is easier to do nesting of
named nodes in RDF/XML.


On the other hands, developers not that much into RDF will find it
hard to find a standard talking about using an ontology which is
described in various different serialisations.

Are you suggesting we do a similar "Hide/show" buttons? With RDF/XML,
Turtle, abstract syntax.. and also the other OWL syntaxes? (Syntaxii?
Syntices?.. well!)


I would find it hard to edit the documents at this early stage if this
is not automatically maintained - but doing so automatically would not
allow us to do "pretty-formatting" - for instance in
http://dvcs.w3.org/hg/prov/raw-file/default/ontology/ProvenanceFormalModel.html#example-workflow-run
I:

* Deliberately used classnames <wf:Value> instead of <rdf:Description>
with the horrible entity-namespace <rdf:type rdf:resource="&wf;Value">
(This is something else to push the RDF WG on, after all XSD manages
this fine)
* Did "natural" nesting such as <prov:used> <wf:ValueAtPort> </>
* List assertions in semi-chronological order so that resources are
asserted before they are used in other assertions

Some of the other examples in the ontology don't have complete
RDF/XML.. I agree that we should not need to include <rdf:RDF and the
namespaces for everything, but should at least include the closing tag
</rdf:Description> to not look too odd.  I'll fix this today unless
anyone screams.
