FHIR RDF spec on github

http://htmlpreview.github.io/?https://github.com/w3c/hcls-fhir-rdf/blob/master/spec/index.html

oops! eric moved it already. he's getting the new link...

<ericP> http://w3c.github.io/hcls-fhir-rdf/spec/

eric: github's convention is that a branch called 'gh-pages' will cause the HTML to be rendered.
... I moved master to gh-pages.
... If you have outstanding commits you need to set your remote to gh-pages
... And I set the default branch to gh-pages

list branches: https://github.com/w3c/hcls-fhir-rdf/branches

scribe: If you do not have outstanding edits, then you should be able to change your remote branch

dbooth: Or just wipe out the copy on your local drive, and do a new 'git clone' of the repository
... That should set up your default branch to be correct: gh-pages

lloyd: Probably want separate pages for what the RDF versus what the OWL looks like. Should model the RDF part after other FHIR pages.

View the draft spec here: http://w3c.github.io/hcls-fhir-rdf/spec/

eric, raw xhtml link needs to be update also, to: https://github.com/w3c/hcls-fhir-rdf/blob/gh-pages/spec/index.html

"See spec/index.html"

GitHub repository -- See spec/index.html

lloyd: Content needs to xhtml instead of html, and the content needs to be split between RDF and OWL pieces.
... Some will care about RDF but not OWL.
... The header/footer are easy enough to add later as long as we are consistent with heading levels, etc.

Here is a draft target, of what the RDF starting page should look like: https://hl7-fhir.github.io/rdf.html

lloyd: We'll modify the ref implementations to parse and produce RDF, and update the build process to convert all of the examples from XML to RDF and round-trip

tony: Add an RDF column?

lloyd: yes. When looking at a particular resource, one change is adding the RDF column. Also under each particular resource, there would be a section on RDF for that resource.
... And on the downloads page, we would add a download for the OWL schemas.

tony: So the build tooling will generate the OWL classes?

lloyd: Yes. Two possible ways to do that. 1. an XSLT that runs on the Structure Definition syntax. 2. Write it in Java and include it in the build process.

dbooth: Should we work the side-by-side doc into the form in https://hl7-fhir.github.io/rdf.html ?

lloyd: Yes. Breaking into separate RDF and OWL pages.
... Right now there is a placeholder for ontology.html, that would have the ontology description.
... If you look at the XML and JSON tabs it is extremely generic, with a few examples. But the particular resources are scattered through the spec, and auto-generated.
... The general principle is to be concise, because developers don't like to read a lot.

tony: Page 1.18.3 is manually written?

lloyd: Yes, with a few things auto-inserted for header/footer, etc.

tony: One deliverable is 1.18.3

1.18.3: https://hl7-fhir.github.io/rdf.html

lloyd: the other is 1.25: https://hl7-fhir.github.io/ontology.html which is under Documentation
... warning: the section numbers may changes

dbooth: Our Deliverables are listed here: http://wiki.hl7.org/index.php?title=RDF_for_Semantic_Interoperability#Deliverables_and_Editors
... We need to split apart #1 to the RDF and OWL pages
... I have updated the deliverables list, to separately list the RDF page and the ontology page: http://wiki.hl7.org/index.php?title=RDF_for_Semantic_Interoperability#Deliverables_and_Editors

eric: In the resource definitions you have the logical table that comes from the structure def, and several tabs for XML, JSON and RDF, with invented languages for describing the data. I was thinking ShEx might be good there.

lloyd: The purpose of the XML and JSON views is to have somethign that looks like what an instance would look like, with some extra metadata embedded in a comment-y way, so that you can paste it into a document and quickly make a valid instance. We should think about what that syntax should look like.

eric: I prototyped that as ShEx so that we can see what it would look like

lloyd: We're really like to have xhtml with highlighting and all, so that we can see how it would look in the spec

<ericP> www.w3.org/2016/FHIR-tutorial/Constellations?shexc

dbooth: Maybe use Turtle annotated with ShEx expressions?

lloyd: Depends on how terse it can be. Want people to have a sense of what the Turtle will look like. The computability of the metadata is not a driver at all. If it is useful we could provide the ShEx representation as an alternative, just as we provide schematron.

dbooth: Could have hover-over that shows the ShEx snippets.

lloyd: Hover-over gives the definitions.
... Want somethign quite readable for someone familiar with Turtle, and it should require as little modifcation as possible to produce valid Turtle after copy and paste.
