Hi all,
On behalf of the AKSW research group[1] I am happy to announce a new
release of LinkedGeoData!
The aim of the LinkedGeoData[2] (LGD) project is to make the
OpenStreetMap[3] (OSM) datasets
easily available as RDF[4]. As such the main target audience is the
Semantic Web[4]
community, however it may turn out to be useful to a much larger
audience. Additionally
we are providing interlinking with DBpedia[5] and GeoNames[6] and
integration of class labels from
translatewiki[7] and icons from the Brian Quinion Icon Collection[8].
The result is a rich, open, and integrated dataset which we hope to be
useful for
research and application development.
The datasets can be publicly accessed via downloads, Linked Data, and
SPARQL-endpoints.
We have also launched an experimental "Live-SPARQL-endpoint" that is
synchronized with the
minutely updates from OSM whereas the changes to our store are
republished as RDF.
The improvements over the somewhat aged previous release in the middle
of 2009
can be summarized as:
. Better data quality thanks to a more flexible mapping system.
. Spatial query support as supported by OpenLink's Virtuoso[9]
enterprise edition.
. Two Sparql-endpoints: one containing the data of the most recent LGD
release,
. and one experimental one synchronzied with OpenStreetMap.org!
. More interlinking
. Improvements on the LGD-Browser (however this is work in progress)
I would like to thank the whole AKSW group and OpenLink for their
support in making
this release possible, especially:
. My supervisors Sören Auer and Jens Lehmann
. Konrad Höffner who did the interlinking
. Patrick van Kleef from OpenLink for his personal support
Furthermore this work is acknowledged by the European Union within the
LOD2[10] project.
Best regards,
Claus Stadler
