Approve Minutes of previous meetings

<dbooth> Last week's minutes: http://wiki.hl7.org/index.php?title=ITS_RDF_Concall_Minutes_20150317

<dbooth> RESOLVED: Minutes of Mar 17 approved!

FHIR RDF and Validation/Translation Task force

<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:

Upcoming HL7 Meeting - Paris

Coming the HL7 meeting in paris

<dbooth> http://www.hl7.org/events/wgm052015/

<dbooth> Claude

<dbooth> Rob

<dbooth> EricP

<dbooth> Paul

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

Paul: The most likely it will be Monday Q4

Potential RDF Mapping Strategies

<dbooth> http://wiki.hl7.org/index.php?title=FHIR_RDF_Mapping_-_Potential_Strategies

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)?

ONC comment on stable URIs (due Friday April 3)

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"
