- Continue requiring SAS-Transport-5 (XPT) as the transport format
- Move to XML (e.g. CDISC Dataset-XML) as soon as possible
- Move to RDF as soon as possible
We had 57 answers (which is considerably less than I had hoped for). Here are the first results:
And here come the results about the question on the exchange format:
Over 50% voted for moving to an XML-based format like CDISC-Dataset-XML, about 25% for moving to RDF. A minority of less than 20% voted for continuation of the current FDA policy to require SAS Transport 5.
I tried to make a detailed analysis looking for relations between the answer about the preferred format and the company type, but didn't find any. The only slight trends I could see (but statistically not significant at all) is that RDF is a bit overrepresented in the "Sponsor" group, and that "SAS-Transport-5" is slightly overrepresented in the "CRO" group. Only 3 (out of the 20) "sponsor voters" voted for "Continue requiring SAS-Transport-5".
The survey also allowed to provide comments. Here are the most interesting ones:
- If it's not broken, don't fix it. Pharma is a big industry and slow to change/adapt
- We must move beyond the restrictive row/column structure
- SDTM is useless and error prone. We need modern data models and semantics
- Consider JSON also. Get rid of Supplemental domains
- Going for RDF means that ADaM, SDTM and the rest could be all linked together ...
