Many cognitive usage scenarios that take place can be 'recorded'. In our federation data recorded in one testbed is usable in other testbeds to support emulated usage scenarios (e.g. primary user data recorded in testbed A feeds into a sensing device in testbed B).

To this end, CREW defined data of interest, common structures for storing data and is in the process of creating a federation database for storage of any collections made.

Information on the common data format can is available in this document. The corresponding tools that have been developed are available on GitHub by following this link.
