Hi Harry, A high-level view of some components can be seen on confluence [1]. While the data-model actually hasn't changed (much?) with these components since they were documented in Confluence, our documentation efforts for this kind of stuff has been focused in the code comments. Even then, while API documentation is plentiful in the code documentation, it would be difficult to track isolated data-model documentation, aside from looking at the CQL queries we're outputting.
To track down the column families schemas we're creating and what they look like, they're created during the initialization phase of the individual OAE modules (see the init.js files in the oae-<modulename>/lib/init.js) You can also use cqlsh or a selection of Cassandra GUI data browsers available to open up the "oae" keyspace and see what's in there. Hope that helps, Branden [1] https://confluence.sakaiproject.org/display/3AK/OAE+Architecture On Wed, Aug 21, 2013 at 11:19 AM, Harry Wang <[email protected]> wrote: > Hi Nicolaas, > > I have a related question: are there documents showing the details of the > data model of OAE?
