Remove default prefix

[Jamie-SA]

I seem to remember seeing something that recommended that ontology files should not have default prefix statements (the blank or : namespace). I don't know why we'd want to use one in gist but I see one in gistCore. I suggest we remove it.

Agreed. @dylan-sa and I observed this somewhere and wondered if Protege was adding it. If so, we could include removing it in the pre-commit hook that deletes the skos annotation declarations.

We would need a process that runs after the serializer to remove the base declaration. Could include in the serializer pre-commit.

DECISION: Include in the serializer pre-commit and the release process.

@sa-bpelakh Please confirm that this is indeed inserted by the serializer before you begin this implementation. Possibly I'm misremembering.

@uscholdm Do we want to ask the EDM Council to add this as an option to the serializer?

[uscholdm]

It worked before, so it might work again - especially since use of Protege is so widespread.

We'd need to have a clear example to hand them. A ton of experiments were done, that would have to be condensed, clear and concise.

I checked, and the serializer does not re-add the default namespace if it is removed manually. If I modify the commit hook to remove it anyhow, and then push in a single commit removing it from every ontology, we won't even need to have it as a step in the build - unless you think someone out there is bypassing the commit hook.

unless you think someone out there is bypassing the commit hook.

That could happen if a setup is not done correctly or gets corrupted.

DECISION: The pre-commit hook should remove the default prefix (similarly to how it removed stub SKOS definitions previously). There is a new issue, #1094, to remove it manually for the 13.0.0 release.
