LESS - Content Syndication based on Linked Data
We’ve announced LESS today - an end-to-end approach for the syndication and use of linked data based on the definition of visualization templates for linked data resources and SPARQL query results. Such syndication templates are edited, published and shared by using LESS’ collaborative Web platform. Templates for common types of entities can then be combined with [...]

Open Knowledge Conference 2010
OKCon, now in its fifth year, is the interdisciplinary conference that brings together individuals from across the open knowledge spectrum for a day of presentations and workshops. Open knowledge promises significant social and economic benefits in a wide range of areas from governance to science, from culture to technology. Opening up access to content and data [...]

ESWC 2010 Semantic Web in Use Track
Some AKSW members are involved in next year’s Semantic Web in Use Track of the Extended Semantic Web Conference 2010. Yes, its called “Extended”, instead of formerly “European”, in order to reflect the broadening of the topics of interest. Next year’s In-Use track is particularly devoted to: Description of concrete problems in specific application domains, for [...]

LinkedGeoData official launch
We are pleased to announce the first public version of the LinkedGeoData.org datasets and services. LinkedGeoData is a comprehensive dataset derived from the OpenStreetMap database covering RDF descriptions of more than 350 million spatial features (i.e. nodes, ways, relations). LinkedGeoData currently comprises RDF dumps, Linked Data and REST interfaces, links to DBpedia as well as a prototypical [...]

OSM Linked Geo Data extraction, browser & editor
We were working in the last weeks on bringing geo data derived from the marvelous OpenStreetMap project to the data web. This work in progress is still far from being finished, however, we would like to share some first preliminary results: A vast amount of point-of-interest descriptions was extracted from OSM and published as Linked Data [...]


LinkedGeoData


Background

Spatial data is crucial for the Semantic Data Web in order to interlink geographically linked resources.
The OpenStreetMap project collects, organizes and publishes geo data the wiki way. Currently the 80.000 Open Street Map users collected data about 22.000.000km ways (roads, highways etc.) on earth. 25.000km are added daily. The Open Street Map database also contains a vast amount of structured information about points-of-interest such as for example shops, amenities, sports venues, businesses, touristic and historic sights.

Aim


The goal of this project is to publish OSM geo data, interlink it with other data sources and provide efficient means for browsing and authoring. We aim at working as closely as possible with both the OSM and LOD communities.

Components

The project currently consists of three components:

  • 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.
