[Data-modeling] Adding a date/time CVT to organization members

[Jeff Prucher]

We have had a request to insert a CVT between the types "organization" and
"organization member" in order to be able to track information about the
periods over which members have belonged to organizations. The CVT will
simply add start and end dates. (The properties that would be affected are
/organization/organization/members and
/organization/organization_member/member_of_these_organizations.) This is a
very straightforward fix to do, but doing so will break any applications
using these properties.  Is anybody using these properties, and if so, would
this be a problem for you?  We'd probably make the change in the middle of
March.
