Hi James

No offence taken.

I think we have to be flexible. In some cases, timeliness is important, and not all details can be worked out. So, just flagging (perceived) problems is important, and should be allowed.

The mapping has proved to be a very effective tool to work out details.  Before reaching that stage, sometimes, a simple conversation between teams can really help. The tracker (and this product) can help conduct this conversation.

Nevertheless, many of the mismatches are things that can be handled by changing one of the products and then (if needed) updating the mapping, but can't be fixed just by changing the mapping.  The reason I wrote the guidelines was that I want to avoid having the mapping become a dumping ground for issues that really "belong" to other products, so that we can focus on issues that really need dialogue between PROV-DM and PROV-O authors/editors.

I am happy to change the guidelines if you think my approach can be improved.  It seems that most of the issues you raised were really about the ontology, so I am happy with your response of re-raising against the ontology.
