refactor(ontology): Make knora-admin a separate ontology

[benjamingeer]

• Change knora-admin.ttl to http://www.knora.org/ontology/knora-admin.
• Add KnoraAdmin object to OntologyConstants and move all relevant properties.
• Make necessary changes to source code so that OntologyConstants works again.
• Change groups inside permission strings from knora-base:GroupName to knora-admin:GroupName in test data.
• Update tests.
• Add upgrade script to update existing repositories.
• Update docs.

Existing repositories must be updated; see upgrade/1263-knora-admin for instructions.

Resolves #1106.

cool, thanks 😀

@benjamingeer Once you have written the update script, could I try it out?

Yes, I was hoping you would. :) I'll let you know when it's ready.

I'm using GraphDB 8.8, I wonder if that's why.

Graphdb 8.5.0 is the version we use in production due to the memory setting problem.

I'll try converting knora-test with GraphDB 8.5 and see if I can reproduce the error that way.

Ok, thanks a lot!

I have just shared another data file on switchdrive with you (data on BEOL test).

[benjamingeer]

@tobiasschweizer I've reproduced the problem with the Knora test data using GraphDB 8.5. I'll try to find a workaround.

[benjamingeer]

@tobiasschweizer @subotic I can't get the update to work in SPARQL with GraphDB 8.5. I'm going to take a different approach: dump the contents of the triplestore to files, update the files, then load the files back into the triplestore.

Do you think you can do it in a way so the two dumps (pre and post update) can be diff-ed?

I think so.

[tobiasschweizer]

Great! Then it is easy to verify whether it worked correctly or not.

[benjamingeer]

@tobiasschweizer You can try the update script again now. It updates knora-test with GraphDB 8.5 in about 2 minutes. The input and output Turtle files are saved in a temporary directory, and you can look at them, but you can't really diff them, because they're not formatted in quite the same way.

[tobiasschweizer]

Ok, I will check it next week

[tobiasschweizer]

I can confirm that the data conversion script worked for me. The changes you made look good to me.

Please inform other Knora developers about this upcoming data conversion task.

@tobiasschweizer Thanks for the review!
