As a point of clarification, a management data repository
(MDR) is defined by the CMDBf spec as any data source that implements a
CMDBf query service, and optionally registration service.  There is
no requirement that SML is used, although we believe that SML makes an
excellent choice for expressing the payload of a graph query response.

Previously in COSMOS, an MDR needed to implement the
data manager interface in order to be "managed" in COSMOS.  However,
I believe this requirement is being relaxed in the future (correct?).
