firstPublisher is not equivalent but subproperty of schema:publisher

[RubenVerborgh]

Currently dbo:firstPublisher is listed as owl:equivalentProperty of schema:publisher. However, since schema:publisher also includes people in its range, and dbo:firstPublisher assumes companies, this leads to inconsistencies.

Thanks for the report @RubenVerborgh For me, the best option would be to change the range of dbo:firstPublisher to dbo:Agent

[RubenVerborgh]

It depends:

• if all values of dbo:firstPublisher are in fact companies, we might like to keep the range
• are first publisher and publisher really equivalent (i.e., why “first”)?

OK, let's analyze a bit. This is not a frequenty used property in DBpedia, http://mappings.dbpedia.org/index.php/Special:WhatLinksHere/OntologyProperty:FirstPublisher

I think it is used to model the original publisher of a work. Checking on the Dutch DBpedia I think that there are a few Persons there as well but my Dutch are not very good :-) can you double check?

Indeed, but it is an edge case. E.g., http://nl.dbpedia.org/page/De_iure_belli_ac_pacis is published by http://nl.dbpedia.org/page/Nicholas_Buon, and Buon is a person. However, it seems to be an identifier problem here: I'm pretty sure they actually mean “the publishing company owned by Buon”.

But in general, let's indeed make dbo:Agent the range of dbo:firstPublisher, then it works in any case. However, I'd still argue to also make it a subproperty of schema:publisher, which does not have the semantics of “original” publisher.

BTW, interesting backstory of on how I found this: I reasoned over my own dataset with the DBpedia ontology in order to publish my own data, and I was surprised to see that I was a company. Turns out that I publish blog posts, so DBpedia made me dbo:firstPublisher, and, consequently, a company.

Actually, looking at dbo:publisher We should both change the range to dbo:Agent and remove the equivalence to schema:publisher

[RubenVerborgh]

:+1:, but subproperty would also be nice and correct.

even better, it's fixed now and will be updated on the next release http://mappings.dbpedia.org/index.php/OntologyProperty:FirstPublisher

@rubenverborgh if you infer any types from Dbpedia domains\ranges, you're in for nasty surprises. Eg

| mother = [[Victoria]], queen of [[England]]

Will infer that England is a person
