Ontology

[elio hbeich <el...@gmail.com>]

Dear All,

I am trying to convert a gml file (building, bridge, etc.) from CityGML to
rdf.
So first i have convert it to CSV bu using geoconverter.
Than i transform the generated file to RDF by using OpenRefine.

I already have the ontology (building for example) i need to tranport the
information from the rdf file to the ontology (how?)

Do u have any idea or suggestion on how to improve my approach

Best Regards,

Elio HBEICh

If you are using the same identifiers in each source, then when you merge them the common identifiers will immediately form links.

Can you explain more this part:
'' If you want to link the two, simply add both to a model or tdb database.
It
will auto link.''

The question is a little ambiguous but what I understand is
- you have a citygml file containing an example city that you have exported
to rdf.
- an ontology (say owl format) for CityGML standard.

If you want to link the two, simply add both to a model or tdb database. It
will auto link.

If however you want to create an ontology, then possibly look at
http://cui.unige.ch/isi/onto//citygml2.0.owl which is one example I found
from Google.
