Will we be able to call this service to get an entire XML record from exist? In the  python coding meeting we decided we 'Need a light interface to exist that respects ndg security ... returns a specific document ...'

This hasn't been made into a ticket yet, and I am wondering if they are part of the same thing?

See  XMLDBMessageService.java which implements 2 methods (so far), fullText() and present().
fullText() executes an XQuery against eXist using XMLDB, and returns the XML result.
present() fetches a document from a URL
...in this case the eXist REST interface, e.g.  http://glue.badc.rl.ac.uk:8080/exist/rest/db/dif/nocs/NOCSDAT114.xml but you could point that at some other thing that exposed docs from the DB if preferred. As the eXist DB is currently password protected, present() uses an Authenticator object to load the username and password from a properties file so that the service can always reach the document. Perhaps this is the bit we could integrate with NDG security to ensure that it is respected. This would probably need to be a new ticket, then.
