Steven Hawkins commented on TEIID-3462:
---------------------------------------

> there is NOTHING we can do to validate the fact that a given minor version of VDB did follow the rules of semantic versioning

That is generally the case with all semantic versioning.  Unless you have a full regression test suite / spec, you are always implicitly trusting the developers that they versioned appropriately.

>  why not we introduce a VDB level property for semantic version, then map this to the "vdb-version", so in cases where we check version number like JDBC connection, odbc connection, Teiid can provide alternative/additional ways to connect using the semantic version. Provide an Admin function to get one version from other. We can also think about re-working "connection type" based on semantic version.

That is somewhat the effect of what I'm talking about with deprecating the version number.  However it does make things awkward to have both concepts - a version/revision and a semantic version.  Keeping the revision as the primary concept you would expect for example that a semantic version based deployment would have an option to auto-increment the old version/revision number.  It seems best to move things in the direction of the semantic version while leaving backwards compatibility initially.  What I'm looking at here from an api perspective is that when the old vdbVersion is >= 1, then we expect the old behavior of just a simple vdb name, otherwise the vdb name should be the full name / semantic version.

> Semantic versioning [1] should be supported in the VDB versioning in order to be able to easier determine whether there are breaking changes from the client perspective and to more easily establish a link between client software versions and the VDBs they rely upon.
