Clinical data REST requests and the 'AdminData' node missing in the result
I am using XML REST requests to retrieve (a) clinical data for groups of subjects, as well as (b) study metadata, and also (c) user data (in the
/ODM/AdminData node). Because of the large size of some of our studies, and the resulting slowness of these requests, it is useful for me to be able to retrieve these three things in one go.
When retrieving data for an entire study (using the
/Study_OID/*/*/* pattern), the 'AdminData' node is returned. However for some reason, when retrieving data for one site in the study (using the
/Site_ID/*/*/* pattern) the 'AdminData' node is missing.
My question is: is there any way of forcing the 'AdminData' node to be returned for site-specific requests? Failing that, is there a (fast) request I can make that retrieves the 'AdminData' node for the entire study, without having to retrieve the entire clinical dataset as well?
PS: I am using the XML version of the REST requests because I use XSLT to transform the result for our purposes.
