Library class is unsatisfied

[jimkont]

Class Library has two super classes that are transitively disjoint

[jimkont]

the analysis was made with http://ore.aksw.org/ using http://mappings.dbpedia.org/server/ontology/dbpedia.owl as a source

It's very common to conflate an organization with its seat or headquarters; eg

• is a country a place or the government that runs it?
• is a city a place or the incorporated entity that runs it?
• IMHO many notable buildings have the same page as the notable organization that inhabits them.

So I'd say that disjoint is wrong.

Dear all, so I understand according to @VladimirAlexiev this is rather "real world" problem that shouldn't be solved in DBpedia ontology, right?

One library may have multiple locations, e.g. Library of Congress - Thomas Jefferson Building and John Adams Building. We can express location by the means of dbp:location and geo:lat/long. In the latter case, there may be some problem with constraints if we exclude categorization as Building. I'm not sure if I'm correct but rdfs:domain for geo:lat/long is geo:SpatialThing (Anything with spatial extent, i.e. size, shape, or position. e.g. people, places, bowling balls, as well as abstract areas like cubes.)

If we take a look at some Library community-related ontologies we'll find that this class is only a subclass of Organization or sometimes called Corporate Body

1. VIVO ontology* - subclass of Organization
2. FRBRoo** and PRESSoo*** - F11 Corporate Body > : E74 Group > E39 Actor

I hope I didn't make any mistake in SPARQL query but I found only 10** cases where libraries are described by the means of properties where rdf:domain is dbo:Place and 2 with rdfs:domain dbo:Building***

I'm not convinced that Library class should be a subclass of Educational Institution. There are different types of libraries, some fall into educational institutions (school, university libraries) some into cultural ones (public, national libraries).

Anyhow, In my opinion, all GLAM institutions should be categorized also directly under an Organisation Now we have: Library = Educational Institution and Building Museum = Building Galleries/Art museum = there is no equivalent DBpedia class. We have: http://dbpedia.org/page/Art_museum Archives - nothing

So I think there is plenty of work to do in case of GLAM All the best, Marcin

And it that case it's likely there'll be 3 pages/entities. But eg the BG library https://en.wikipedia.org/wiki/SS._Cyril_and_Methodius_National_Library has only one page, consequently its WD item https://www.wikidata.org/wiki/Q631641 also describes the building (located in the Oborishhte neighborhood, coordinates etc).

And yes, WGS (the simplest geo ontology) took the simplifying decision that wgs:SpatialThing can be anything.
