<dbooth> Last week's minutes: http://wiki.hl7.org/index.php?title=ITS_RDF_Concall_Minutes_20150317
<dbooth> RESOLVED: Minutes of Mar 17 approved!
<dbooth> TF notes: http://www.w3.org/2015/03/18-hcls-minutes.html
Reviewed some tools to generate FHIR ontology
still reporting: leverage the XML Schemas in mapping back from RDF to XML to get the correct sequences
the task force looked also on some previous work on parser of the structure and schema/hierarchy
<dbooth> http://hl7-fhir.github.io/elementdefinition.html#tabs-ElementDefinition-struc
dbooth: following action point of what this page means
ericP: The page define some hierarchy / resources
the question is if this page contains something we can use
dbooth: The next topic:
Coming the HL7 meeting in paris

I will not be able to attend , sorry
<Tony> I will not be able to attend
attendance: Claude, Rob, ErirP, Paul --- Not attending: Marc, David
But David can attend remotelly
<dbooth> Paul: ITS quarter is available for discussion
dbooth: If there will be a ITS
call it will be late in the day
... Which day >> To Paul
Paul: There are Q3 and Q4 scheduled on Tuesday
dbooth: look where you can manage and anyone else can join
Paul: what was experience last time,
Ingeborg: small problems with bandwith, etc

Next Topic: Mapping strategies
http://wiki.hl7.org/index.php?title=FHIR_RDF_Mapping_-_Potential_Strategies
Tony: Do we have different strategies already
The 3 strategies so far:
1-use with ShEx
2- Using JSON-LD
3- using JSON-LD but having 2 styles
dbooth: The difference of the 1 and the other 2 is the use of the @context
Tony: In previous meeting we
agreed that there will be parallel exploration betwwen JSON-LD
and RDF
... JSON-LD is not RDF
... Looking on requirement 14
... We discussed to do a parallel exploration
... we should focus on the formats which are supported
<>: Why we cannot support both?
Tony: the RDF XML is the most supported serialisation
dbooth: We should rise the issue: what seriariazation to use
<dbooth> ISSUE: What serializations should we specify?
<trackbot> Created ISSUE-4 - What serializations should we specify?. Please complete additional details at <http://www.w3.org/2014/HCLS/track/issues/4/edit>.
Marc: The RDF/XML is not digestible maybe we need to use the most human readable
dbooth: why do we need to choose an RDF serialization?
correct: not <why> but <what>
Tony: a subset of serialization
dbooth: if we go in RDF road the format will be already fixed
Paul: We will use existing serialization we will not develop a serialization
<dbooth> dbooth: If the FHIR group adopts a third serialization, then we need to specify what that is
Tony: JSON-LD can be used but
there's no plug-in yet
... I think we need to develop it first
dbooth: There JSON-LD
implementation from W3C
... so far we have followed the parallel ways and the target is
to converge on single approach
<dbooth> Requirements are here: http://wiki.hl7.org/index.php?title=FHIR_Ontology_Requirements#14._RDF_Quality
Tony: It must be something which can be imported into progege or something else
<dbooth> "(MUST) Transformations into RDF must meet software quality checks including ontological closure. The RDF instance which is transformed from FHIR XML or FHIR JSON must be capable of being opened without further modification by widely available tools including Protégé and the RDF must meet quality checks including successful closure of graphs - all the links are understood by the tool."
<>: No big reason to have several
dbooth: probably we are reading
the requirement 14 differently
... if we use JSON-LD that RDF serialization will not be
transmitted on wire
Tony: What is transmitted on the
wire should be the one translated
... I believed that RDF will be exchanged on wire
dbooth: The JSON-LD is also RDF
Paul: there's no absolute to do another serialization if we use JSAON-LD
correct: JSON-LD not JSAON-LD
dbooth: If JSON-LD is used there will be no further serialization/transformation
Claude: client side or FHIR side?
<>: client side or FHIR side?
Paul: The server
Tony: we would have different documentation of which format/serialization we use
Paul: You do not really need
transformation mechanism at application side
... the life would easier if you design your application to be
based on the FHIR structure
Tony: There's a coupling between
RDF and transports
... using URIs is a must
dbooth: this a different concern
<dbooth> dbooth: Question is whether it is important to our goals to have an RDF *serialization* transmitted on the wire (or available directly from a file)?
dbooth: we are running out of
time, let's come back on them next week
... before we leave we need to make a comment on "ONC comment
on stable URIs"
