How strict should a KGCL applicator be?

[gouttegd]

Had there been any discussion as to what behaviour one should expect when trying to apply a KGCL change that does not fully match the existing ontology?

For example, considering the following changeset:

rename EX:1234 from 'alice' to 'bob'
create exact synonym 'robert' for EX:1234
remove definition for EX:5678

What is the expected behaviour if the rdfs:label of EX:1234 is not “alice”?

I can imagine 4 different options:

• Relaxed: Apply changes where possible even where there is a mismatch. In this example, EX:1234 should get the new label “alice” regardless of what its existing label is.
• Change-level strict: Reject any change where there is a mismatch, apply all other changes normally. In this example, reject the first change, apply the others two.
• Node-level strict: If there is a mismatch in one change, reject all changes that are related to the same node. In this example, reject the first two changes (since both are about EX:1234), apply the last one.
• Changeset-level strict: Only apply the changes in a changeset if they all can be applied cleanly, reject the entire changeset for any mismatch in any change. In this example, all three changes would be rejected.
