HACK

Spacenamespace is an evolving spatial ontology, initially based on the classi-

fications extracted from GEONet data

[Hack #84]. It was written as part of a

spatial annotation project, mudlondon; the ontology was expanded by some

of the MUD users:

<owl:Class rdf:about="http://frot.org/space/0.1/Building">

<rdfs:label>a Building</rdfs:label>

<rdfs:subClassOf rdf:resource="http://frot.org/space/0.1/Hypsographic"/>

</owl:Class>

<owl:Class rdf:about="http://frot.org/space/0.1/Public_Building">

<rdfs:label>a Public Building</rdfs:label>

<rdfs:subClassOf rdf:resource="http://frot.org/space/0.1/Building"/>

</owl:Class>

<owl:Class rdf:about="http://frot.org/space/0.1/Recreational_Venue">

<rdfs:label>a kind of Public Building intended for recreational purposes,

like a cinema or club.</rdfs:label>

<rdfs:subClassOf rdf:resource="http://frot.org/space/0.1/Public_Building"/

>

</owl:Class>

This formidable-looking bit of RDF says, “A Building is a kind of Hypso-

graphic Feature.” Hypsographic is a top-level classification from GEONet

and just means something that’s found on land. It goes on: “A Public Build-

ing is a kind of Building, and a Recreational Venue is a kind of Public Build-

ing.” Each unique kind of space in a MUD can be labeled with one or more

URLs, helping to indicate to people or bots the kind of things that can hap-

pen there. ...
