Frederik Malfait review of PhUSE / CDISC work

<Claude> Please join: https://global.gotomeeting.com/join/157514853

Frederik: goal is to use W3C standards for clinical trials data.
... Biggest work has been done on existing clinical trials work in RDF.
... Looking at applying RDF Data Cube to analysis metadata.

slide 7 of http://tinyurl.com/CDISC-Webinar-PDF

Frederik: Data currently published as PDF and spreadsheets.
... In CDISC looking at W3C semantic standards.

<Kerstin> http://www.w3.org/TR/tabular-data-model/

David: W3C is now working on CSV metadata standards

Frederik: Want an RDF representation of CDISC data.

<Marc_Twagirumukiza> did you created local ontology or you used 3rd party ones?

Frederik: Made from scratch.
... We found an old one, actually used in Roche. But you run into difficulties when you start with a theoretical model. We didn't find anything suitable already, so we built one. Very practical focus.
... Now published on github. CDISC now points to it.
... 6 weeks of public review ends on Feb.

<Kerstin> Annoncement on CDISC website: http://www.cdisc.org/standards/dataexchange

Frederik: Should become an official CDISC standard in 2015. They are also developing a SHARE system, and we want to be able to export RDF from that. Hope to align with what we have in github.

slide 27

SDTM = Study Data Tabulation Model

Second presentation: http://tinyurl.com/PRG-meeting-PDF

Ingeborg: I was creating a trial summary dataset. Some info on clinicaltrials.gov, which does not always follow the CDISC code set. Ended up going back to spreadsheets, because I did not see a good way to use that RDF file. Comments?

Frederik: To be able to use it on the scale I'm describing you need to put the infrastructure in place.
... It isn't a one-person effort. You need to build systems around it. We built a metadata repository.

David: Ingeborg, was the problem that other data that you wanted to join was not in RDF?

Ingeborg: Partly, but also didn't have an easy way to query and browse the data. E.g., wanted to pull out all the country codes.
... But I'm an RDF beginner.

David: How much uptake on CDISC in RDF?

Frederik: We're at the beginning, but we were able to convince CDISC to pay attention and do an RDF export from their system. Once we have a protocol in place we can teach people how to use it.
... It will take evangelizing, but I'm surprised at how many people sign up on the working group.
... 25-30 people working on it.

Ingeborg: Is there value in being able to do queries across datasets that you could not previously do?
... Payoff or benefit of RDF?

Frederik: Not yet presenting clinical trials data yet in RDF.
... But we are managing our standards now.
... And we have workflow information ... automated builds. That's a huge payoff.

<Alejandra_> Going back to slide 7 in the second presentation, what kind of data is the one at the bottom of the diagram then? And what is the interpretation of RDF as a meta-meta-model?

Frederik: $60M cost normally, but much easier in RDF.

San Antonio planning

1. Update on the RDF group's progress in general

2. Have someone lead a hands-on FHIR RDF hacking demo

3. Hash out FHIR RDF/ontology requirements

4. FHIR RDF use cases

<Kerstin> Recomend aslo Frederik's abstract from Int Semantic Web Conference Industry Track https://dkm-static.fbk.eu/resources/iswc2014/proceedings/ISWC2014IndustryTrack-Extended%E2%80%93Abstracts.pdf

Paul: Suggest a 15 minute "here's how you represent something in RDF"
... Also RDF and it's purpose, and what it looks like.
... ITS people are comfortable with codings, etc., but not so familiar with RDF.

<hsolbrig> Go to meeting shut down so I lost the audio

Paul: Also spend a little time now "why we're doing this"

<ericP> so +1 to Paul's plea for a "why?"

harold, call 617 761 6200 , code 4257

<ericP> meeting's run over so he may not be able

Claude: Time to plan the road ahead, and project scope statements (such as FHIR ont), and maybe dicuss other areas where RDF may be beneficial

<Zakim> ericP, you wanted to say that it's worth impressing ITS folks with what SemWeb machinery can do with clinical data

Eric: Regarding Pauls' suggestion, it's worth impressing ITS folks with what SemWeb machinery can do with clinical data
... Cook up a couple of use cases, such as Claude's CDS use case or Tony's, then we could show out-of-the-box inference machinery.
