15:05:38 <dbooth> Topic: Join the W3C Semantic Web for Healthcare and Life Sciences community group

15:14:16 <dbooth> grahame's editing policy: http://wiki.hl7.org/index.php?title=RDF_for_Semantic_Interoperability#Edits_to_the_FHIR_RDF.2Fontology_pages
15:17:10 <dbooth> eric worked on this page: http://w3c.github.io/hcls-fhir-rdf/spec/rdf.html
15:17:37 <dbooth> as a potential new version of https://hl7-fhir.github.io/rdf
15:32:10 <dbooth> https://hl7-fhir.github.io/
15:39:38 <dbooth> eric: I propose renaming the ontology page to Linked Data.
15:48:54 <dbooth> dbooth: The proposal: 1. rename ontology-module.html to linked-data-module.html 2. change the title to "FHIR Linked Data Module".
15:49:32 <dbooth> ... 3. On the FHIR home page, put links to RDF and Ontology pages in the Linked Data module box
15:51:00 <dbooth> eric: Another proposal: rename the title of page https://hl7-fhir.github.io/rdf to match the XMl and JSON pages: "RDF Representation of Resources"
15:52:41 <dbooth> eric: Regarding deliverable 4. Formal specification of FHIR/RDF http://w3c.github.io/hcls-fhir-rdf/spec/

21:26:32 <trackbot> Date: 23 August 2016
21:26:34 <dbooth> Topic: How to name the resource root when its location is unknown?
21:26:43 <dbooth> https://github.com/w3c/hcls-fhir-rdf/issues/18
21:30:41 <dbooth> dbooth: potential options: blank node, relative URI, or skolem URI
21:30:51 <dbooth> ... A relative URI looks like <>
21:31:54 <dbooth> eric: i favor <> (the base URI)
21:32:17 <ericP> GET http://a.example/some/path -> <> a fhir:Foo; fhir:identifier [ ... ]
21:32:32 <dbooth> grahame: That would allow only one unidentified URI in scope at at time?
21:32:54 <ericP> <http://a.example/some/path> rdf:type fhir:Foo .
21:33:09 <ericP> <http://a.example/some/path> fhir:identifier [ ... ].
21:33:46 <dbooth> grahame: If I have two unidentified resources in the same graph then this would not work.
21:33:53 <ericP> GET http://a.example/some/path -> <other/path> a fhir:Foo; fhir:identifier [ ... ]
21:33:59 <ericP> <http://a.example/some/other/path> rdf:type fhir:Foo .
21:34:03 <ericP> <http://a.example/some/other/path> fhir:identifier [ ... ].

21:35:03 <tlukasik_> tlukasik_ has joined #HCLS
21:36:39 <dbooth> dbooth: I'm against relative URI because they don't exist at the RDF level.  In RDF *every* URI is absolute.
21:37:47 <dbooth> grahame: this example is different: http://hl7-fhir.github.io/parameters-example.ttl.html
21:38:21 <Grahame> Grahame has joined #hcls
21:38:55 <Grahame> ....Eric made me do it....
21:39:58 <dbooth> dbooth: i think a blank node would be best aligned with the RDF model.    A relative URI would become absolute when interpreted as RDF, and I'm concerned that it would not round trip well
21:41:03 <rhausam> rhausam has joined #HCLS
21:41:18 <dbooth> grahame: XML and JSON forms do not include the address of the content.  The RDF form does.  That's why we say that the Turtle is for reasoning, rather than interop.
21:42:10 <dbooth> dbooth: We haven't nailed down what constitutes round tripping.
21:42:30 <dbooth> grahame: For xml and json we say that the canonical form must be identical.
21:44:39 <dbooth> ISSUE: Define canonical FHIR RDF https://github.com/w3c/hcls-fhir-rdf/issues/34
21:44:40 <trackbot> Created ISSUE-39 - Define canonical fhir rdf https://github.com/w3c/hcls-fhir-rdf/issues/34.  Please complete additional details at <http://www.w3.org/2014/HCLS/track/issues/39/edit>.
21:46:24 <dbooth> eric: Do we need to specify how the root node should be named?
21:47:36 <dbooth> grahame: If we say that it is a URI, but might not be unique, then if people merge data that could be a problem.
21:48:43 <dbooth> dbooth: I.e., if a relative URI is used <> then different data might accidentally use the same URI and users would not realize it.
21:50:19 <dbooth> eric: An advantage of a relative URI is that they can do sparql queries using that node and its name is stable.
21:52:11 <dbooth> grahame: We could put a warning in the spec.
21:54:19 <dbooth> dbooth: in round tripping RDF-->XML/JSON-->RDF, I don't want my URIs disappearing.
21:54:54 <dbooth> grahame: There's no place to put that URI in the XML or JSON
21:57:00 <dbooth> dbooth: We might agree to let the user decide whether to use relative, abs or blank node.
21:57:26 <dbooth> dbooth: What should we put in the examples?
21:57:37 <dbooth> eric: Relative URIs
21:57:54 <dbooth> dbooth: still against relative URIs in the examples.
21:58:19 <dbooth> dbooth: Prefer blank node used in the examples.
22:01:30 <dbooth> Eric agrees to blank node
22:02:50 <dbooth> AGREED: In the examples, we will use a blank node for the root node of the resource
