  1. metamodeling forms a study period report Denise Warzel, NCICBIIT Jim Davies, Charles Crichton, Andrew Tsui, James Welch, Steve Harris* Department of Computer Science, Oxford Daniel Abler, CERN

  2. agenda • why might we need one • what instances already exist • what are their common features • what one might look like • what would be its scope • where do we go next

  3. motivation • specification • I want this data to be collected • interoperability • we should be collecting this data • we have collected this kind of data before • documentation • this is how this data was collected • no, this is what this data means

  4. motivation … • discovery and reuse • of data • was any data like this collected? • of form designs • can I save some time here? • is there some way of collecting this kind of data that is validated? • model driven software engineering • I need to guarantee that my system collects the data I have described • I need bespoke functionality, not bespoke software • I want my software to be more general

  5. examples – in paper • euro QoL • TCGA follow-up form (NCI, partial specification) • business process templates

  6. examples - electronic • open clinica/redcap • slot extensions in EAP software • caDSR • CDISC ODM • HL7 CDA • DDI 3.x

  7. metamodel elements • identification • static structure and mapping • validation • control logic/flow

  8. metamodel elements - structure • questions • typing • instruction text • their relationship to data elements • sections • their relationships to other sections on other forms • the container • essential annotation of scope

  9. metamodel elements - validation • field-level data checking logic • narrows typing information from ISO11179 • account for dependencies (scope?) • default values

  10. metamodel elements - flow • ordering • paging • skip logic • to what extent is style in scope?

  11. administered item terminology value domains data elements models

  12. scope • not a data model or a workflow model • although clearly related • not an implementation • although it has to encompass XForms, webforms, JSF, ASP.NET forms … • maybe has elements of a meta-standard • may specify constraints on DSLs for validation/flow control/skip logic/workflow

  13. scope … • will describe how to specialise ISO/IEC11179 data elements into questions • will specialise ISO/IEC19763 – is it simply another component standard of the family • will reuse administration modeling from this workgroup

  14. next steps • approval to begin turning the research into a standard • advice on how the standard is structured and presented • abstract or concrete metamodel? • multipart? • specification + guidance notes?
