ODM Presentation Tag


I'm a computer science student (at the RWTH Aachen University, Germany), and currently in research for my master thesis which should hopefully result in some kind of presentation semantic for ODM. The thesis will be about developing a generic “presentation layer” for ODM-XML to allow a consistent i) presentation of CRFs between different EDCs (independent from used platform) and ii) archiving and recovering studies including the CRF layout. During my research, I discovered that the CDISC seems to be aware of the problem and specified the “Presentation-Tag”, which is a function-less stub at the current release (ODM 1.3.2), see: http://www.cdisc.org/system/files/all/generic/application/octet-stream/o... 

  • Are there any documentation or protocols, publicly available, when and why this element has been introduced?
  • What was the intention and why has it not been defined further?
  • Would it be possible to get in touch with a responsible team member?

 Also I'm happy about any "practical" or "quasi standard" hint, as for example: "hey, in our daily routing we use XForms, why not use that?!". I would really appreciate any kind of answer and thankfully respond to questions.

I haven't seen any study design in ODM where the ODM element "Presentation" is really used. The "future development" has never taken place... I am already propagating the use of XForms for about 10 years now, and have written software (about 8-9 years ago) that automatically transforms ODM Study designs in a set of XForms files (see e.g. http://www.xml4pharma.com/ODMinEDC/ODMXForms.html). The IHE profile RFD (Retrieve Form for Data Capture) used XForms for their CRFs using a Firefox plugin which does not exist anymore. Better is to use a server-side implementation like BetterForm or Orbeon. Some seem to have picked this up very well. Check the excellent work of the group around Prof. Dugas in Münster that are using the XRX paradigm (XForms, REST, XML-database). I am a "responsible team member" of the ODM team (whatever that means...)
