@apdavison : can you please assign this issue to a month-milestone? Thanks

[apdavison]

My goal for this is 2019-04 (i.e. halfway through SGA2)

[alex4200]

Ok, then we can leave it in "Other tasks"...

[alex4200]

Should be ready by end of October/Begin November.

Just to be clear.... the Model Catalog is expected to be ready (integration with KnowledgeGraph) by the above mentioned target (early November). The validation service as a whole is expected to take a while longer. The currently set milestone (M12: March 2019) seems appropriate.

[appukuttan-shailesh]

Model Catalog integration with KnowledgeGraph is going to take a bit longer than initially expected. The M12 (March 2019) milestone looks fine for the model catalog, but the validation service as a whole might need a bit longer. Better to revisit in M12 and re-evaluate if necessary.
