If you plan to use a local Virtuoso LGD instance, please read http://docs.openlinksw.com/virtuoso/rdfsparqlgeospat.html for geometry related features.

Deletions:

the full data set is very large and is difficult to query efficiently for most SPARQL endpoints given standard hardware

* The data is based on the Open Street Map.org planet file from 6th April 2011.
* The “relevant” in the dataset names indicate that only a relevant subset of the openstreetmap.org planet dataset was transformed to RDF. Of course relevance depends on the application.
* The RelevantWays dataset only contains ways that do not contain more than 20 nodes.
* The node positions use of a Virtuoso-specific datatype that is not supported by the open source edition. || ||#

The “relevant” in the dataset names indicate that only a relevant subset of the openstreetmap.org planet dataset was transformed to RDF. Of course relevance depends on the application.
The RelevantWays dataset only contains ways that do not contain more than 20 nodes.
The node positions use of a Virtuoso-specific datatype that is not supported by the open source edition. Attempting to load such dataset results in an error. Therefore we are planning on providing the node positions in different flavours/vocabularies.
Details of the mapping and filtering configuration used to create the datasets will be published at a later time. || ||#
