Additions:

Open Street Map data extraction currently works on the basis of OSM database dumps. A live-sync module keeps the data in our SPARQL endpoints up-to-date.
LinkedGeo Data browser is based on Javascript widgets, which can display the data from the Linked Geo Data SPARQL endpoints. Support for endpoints of other projects in the works.
A Server providing a Linked Data Interface and a REST API, that grants access to RDFized data based on a (relational) OSM database.

The data can be accessed via Downloads, SPARQL Endpoints, and the REST API.

Open Street Map data extraction currently works on the basis of OSM database dumps, a bi-directional live integration of OSM and our Linked Geo Data browser and editor is currently in the works.
Triplify spatial data publishing, the Triplify script for publishing linked data from relational databases is extended for publishing geo data, in particular with regard to the retrieval of information about geographical areas.
LinkedGeo Data browser and editor is a facet-based browser for geo content, which uses an OLAP inspired hypercube for quickly retrieving aggregated information about any user selected area on earth.

AKSW at TU Dresden PLT
On June 8, I (Jens) visited the process control engineering research group (PLT) of Leon Urbas at the Dresden University of Technology. We first met on the Leipziger Semantic Web Day where Leon Urbas presented interactive Linked Data applications and decided to have a longer meeting later on. I first gave a talk on the [...]

LinkedGeoData Release 2
The AKSW research group is happy to announce a new release of LinkedGeoData! The aim of the LinkedGeoData (LGD) project is to make the OpenStreetMap (OSM) datasets easily available as RDF. As such the main target audience is the Semantic Web community, however it may turn out to be useful to a much larger audience. [...]

May 4-5: Leipziger Semantic Web Tag 2011 and Local Media Conferenz
Like in the past two years, we again organize a Leipzig Semantic Web Day on May 5th at the marvelous Mediencampus Villa Ida. This year’s theme is “Linked Data� for the Masses”, particularly focusing on its use in enterprises. This event will not only give you the opportunity to discuss current developments around semantic web [...]

Semantic Web Journal launched
A short while ago the Semantic Web Journal was launched. Pascal Hitzler and Krzysztof Janowicz are editors-in-chief and AKSW’s S�ren Auer serves on the editorial board. The journal published by IOS Press differs from other journals, in particular, since it follows an open and transparent peer-review process, which engages a wider community besides expert reviews. [...]

Dedicated Virtual LinkedGeoData Server
Due to the rising interest in our LinkedGeoData project and the growth of the underlying OpenStreetMap database, we expanded the AKSW server infrastructure. LinkedGeoData will gradually move to a new server running Debian within the next weeks. This server runs on a virtual machine inside a new cluster at the University of Leipzig. Resources (memory, [...]

NLP Interchange Format (NIF) 1.0 Spec, Demo and Reference Implementation
The NLP Interchange Format (NIF) is an RDF/OWL-based format that aims to achieve interoperability between Natural Language Processing (NLP) tools, language resources and annotations. The core of NIF consists of a vocabulary, which can represent Strings as RDF resources. A special URI Design is used to pinpoint annotations to a part of a document. These [...]

DBpedia SPARQL Benchmark paper wins ISWC2011 best-paper award
The closing ceremony of ISWC2011 in Bonn is just over and we are excited to have won the best research paper award with our paper: Mohamed Morsey, Jens Lehmann, S�ren Auer, Axel Cyrille Ngonga Ngomo: DBpedia SPARQL Benchmark ? Performance Assessment with Real Queries on Real Data. To appear in Proceedings of 10th International Semantic [...]

ISSLOD 2011, a great success!
20 students from about 10 different countries were in Leipzig last week, from 12 – 18 September, to attend the Indian-Summer School on Linked Data. Right from the basics of Linked Data, introduced by Chris Bizer and S�ren Auer, they learnt about the intricate details of Linked Data such as Interlinking, Conversion, NLP, Reasoning, SPARQL, [...]

Issues

The Linked Geo Data project is work in progress. The following issues exist:

Linked Geo Data.org is not yet bi-directionally live synchronized with OpenStreetMap, updates however are pushed back through OpenStreetMap via its REST API,
the information schema might require some cleansing and/or mapping to existing vocabularies,
no data dumps are yet provided for download.

We are working on resolving these issues, so stay tuned by monitoring our blog or subscribing to the LOD mailinglist.
