You need to query the module baseline explicitly to get the baseline information.
https://jazz.net/wiki/bin/view/Main/RRCReportableRestAPI
When you publish a baseline version of the module, it appears that there is no indication whether the content is from a baseline.

Hi,

you can publish data from DNG modules, see below.

>>> If there is no way to determine whether you are publishing a baseline or not how would you know whether or not to query for baseline information? And for which baseline?
The only way I could do this is to pass the ID of the baseline to the RPE template as a report variable.  See the note on the "module baselines" entry in https://jazz.net/wiki/bin/view/Main/RRCReportableRestAPI for how you could access the list of module baselines but as noted in the API that API is not a valid data source for RPE. The main problem is the lack of a schema provided for it.

Greg,

See this http://rpeactual.com/2014/08/08/publishing-dng-module-baseline-metadata/ for a workaround.
