CDISC2RDF overview with examples

  1. 1. CDISC2RDF • CDISC2RDF started as a cross-pharma pre- competitive project with AstraZeneca, Roche, W3C et al. to show case Semantic Web standards and Linked Data principles. • Now part of the Semantic Technology project, in the FDA/PhUSE working group for Emerging Technologies, with 30+ representatives from FDA, CDISC, pharma:s, CRO:s and software vendors. • And also, connected to the convergence now happening across six research projects targeting Semantic Interoperability for Clinical Research & Patient Safety (EU IMI and FP7 projects)
  2. 2. CDISC2RDF Human readable documentation in PDF:s, Excel:s (and some in XML) “Text strings” URI:s (Uniform Resource Identifiers) as “phone-numbers” for each part in the standards: variables, domains, code lists, classifiers etc. http://rdf.cdisc.org/sdtm-1-2/schema#Classifier.RecordQualifier http://rdf.cdisc.org/sdtmig-3-1-2/std#Column.AE.AEACN http://rdf.cdisc.org/sdtm/ct#C66767.C49505 Machine processable linked data structured as RDF triples 1 2 3 1 2 3 CDISC2RDF Schemas Serializations of RDF triples in XML, Turtle, JSON, CSV … Based on the core ISO11179 model Being used to annotate the existing Excel files to transform to RDF using off-the-shelf tools “Record Qualifier “ “AEACN“ “DOSE REDUCED” for “Action taken with Study Treatment” 1 2 3 1 2 3
  3. 3. Examples • Record Qualifier (SDTM Model 1.2 ) • AE Action Taken variable (SDTM IG 3.1.2) • Term “DOSE REDUCED” for “Action taken with Study Treatment” (SDTM CT) 1 2 3 RDF triples: Subject Predicate Object

  5. 5. SDTM IG 3.1.2 SDTM 1.2 Model SDTM CT RDF triples representing one variable/data element and also linked to related standard parts 2 1 3 Serializations of RDF triples in XML, Turtle, JSON, CSV … CDISC2RDF Schemas Being used to annotate the existing Excel files to transform to RDF using off-the-shelf tools
  6. 6. SDTM IG 3.1.2 SDTM 1.2 Model SDTM CT RDF triples representing one variable/data element linked to related standard parts 2 1 3 Serializations of RDF triples in XML, Turtle, JSON, CSV … CDISC2RDF Schemas Being used to annotate the existing Excel files to transform to RDF using off-the-shelf tools
  7. 7. RDF triples representing one Classifier of variables/ data elements defined in other parts of the standard SDTM Model 1.21 SDTM IG 3.1.22 Serializations of RDF triples in XML, Turtle, JSON, CSV … CDISC2RDF Schemas Being used to annotate the existing Excel files to transform to RDF using off-the-shelf tools
  8. 8. RDF triples representing one term for one controlled term list being used in other parts of the standard SDTM CT3 SDTM IG 3.1.2 2 Serializations of RDF triples in XML, Turtle, JSON, CSV … CDISC2RDF Schemas Being used to annotate the existing Excel files to transform to RDF using off-the-shelf tools
