Attributes of revisions of a service are identified and maintained. The attributes include immutable data identifying the revisions, times associated with generation of the revisions, connection data associated with accessing the revisions, and other services used by the revisions. The attributes also include mutable data indicating whether the revisions are compatible with various versions of the other services. A discovery request is received from a requesting device, and discovery request identifies versions of the other services used by the requesting device. A revision of the service that is compatible with the used versions of the other services are identified based on the attributes. The identified revision and connection data are identified to the requesting device. The attributes are updated, and a different revision may be identified to the requesting device based on the updates.
