Finishing Line
• Update a few remaining namespaces for consistency• Final check of the CDISC schema• Final check of the domain assumptions• Consistent formatting of the import files• Dirty work
– typo’s, trailing blanks, non-ASCII characters etc.• Code repository
– github.com/phuse-org/rdf.cdisc.org

Next Steps
• Call for review of draft models• Discuss ownership process with CDISC• Discuss SHARE export facility to RDF• Alignment and final edit

• Represent SDTM and ADaM validation rules in RDF• Implementation algorithms will not be represented
Objective
![Page 20: Emerging Technologies](https://reader035.vdocument.in/reader035/viewer/2022081515/568156ce550346895dc466bc/html5/thumbnails/20.jpg)
• ADaM standard includes validation rules• Identifying all validation rules associated with an SDTM
(ADaM) domain or variable is a non-trivial, manual task• Vendor-agnostic representation of SDTM validation
rules
Rationale
![Page 21: Emerging Technologies](https://reader035.vdocument.in/reader035/viewer/2022081515/568156ce550346895dc466bc/html5/thumbnails/21.jpg)
• Define an ontology for validation rules• Identify version(s) of SDTM/ADaM validation rules for
representation• Link the RDF representations to CDISC standards
represented in RDF

Protocol Representation in RDF

Tasks
• Represent Schedule of Assessments in RDF• Represent Trial Design in RDF• Represent the PRM in RDF
![Page 24: Emerging Technologies](https://reader035.vdocument.in/reader035/viewer/2022081515/568156ce550346895dc466bc/html5/thumbnails/24.jpg)
Challenges
• PRM primarily BRIDG based, unlike CDASH/SDTM• End of Year, deadlines
![Page 25: Emerging Technologies](https://reader035.vdocument.in/reader035/viewer/2022081515/568156ce550346895dc466bc/html5/thumbnails/25.jpg)
Approach
• Read and understand– Study Design Model (XML)– Protocol Representation Model (PRM)
• Identify key components– Classes– Properties
• Model using XLSX and TopBraid

Approach (cont.)
• Consultation– Dave Gemzik (head of PRG)
• Expectations– ~ 1hr + 1hr
• Communication– PhUSE Wiki– Email– Team meetings
