The REST interface and the URIs are being reingineered

Currently the interface and data are not 100% stable.

Additions:

Online access is provided via a SPARQL-Endpoint and a LinkedData-Interface. Downloads are available here.
These online accessible datasets are based on an OSM plant dump from April 2010.
There are plans to synchronize the Linked Geo Data datasets with the OSM minutely replicates in the near future, however this feature is currently not available.

NEW! SPARQL Endpoint

We now have a SPARQL Endpoint powered by OpenLink's Virtuoso database system.
Currently the reduced Node Tags and Way Tags datasets are loaded.
In this section example queries will be gathered.

Also, the distinction between information and non-information resources (the distinction between an entity of osm and what it represents in the real world) is no longer made with hash-URIs, instead 303 redirects are used. This means that
