This is just an extended tweet… Masahide Kanzaki has just posted an announcement on the LOD mailing list on releasing some data he collected on the radioactivity levels on different places in Japan, enriched with metadata (e.g., geo data or time). Though the original data were in PDF, the results are integrated in RDF with a SPARQL endpoint. He also added some visualization endpoint that gives a simple visualization of the SPARQL query results:"

Via XML.
Retrieval of triples from relational databases is a popular topic in the semantic web world, but I was recently wondering how much trouble it would be to go in the opposite direction: to retrieve data from a SPARQL endpoint and load it into a relational database. It wasn't much trouble at all. When you retrieve the results in the SPARQL query results XML format, a straightforward XSLT spreadsheet can convert it into the necessary SQL INSERT statements. I was able to automate the data retrieval, conversion to INSERT statements, and actual insertion into a MySQL database with a three-line batch file that used no Windows-specific tricks, so I'm sure it would work on Linux just as well."

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. Additionally, we are providing interlinking with DBpedia and GeoNames and integration of class labels from translatewiki and icons from the Brian Quinion Icon Collection.
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 following post is from Friedrich Lindenberg, who is a developer at the Open Knowledge Foundation working on CKAN, PublicData.eu and Open Spending.
Recently, there has hardly been a week in which there hasn’t been an announcement of a new local, regional or national open data initiative – including ever more extensive catalogues of data that is being opened up (CKAN alone now runs in 20 or more places). While this is great news for those of us interested in re-using the data, it also means it becomes increasingly hard to keep a good overview of what kind of data are available for which places. To get a better overview we’ve now started a meta search engine for open data, opendatasearch.org."

(by Ton Zijlstra)
The Spanish Cadastre has launched a mass download service for cadastral data, allowing re-use by citizens and businesses for both commercial and non-commercial purposes. The official launch of the service (which we announced late March) was attended by over 300 people from almost 200 interested organizations.
Data on 75 million real estate properties in Spain can now be accessed for download an re-use, and ensures free access to all digital cartography material. This is a massive amount of data."

inkdroid › DOIs as Linked Data: "DOIs as Linked Data
Last week Ross Singer alerted me to some pretty big news for folks interested in Library Linked Data: CrossRef has made the metadata for 46 million Digital Object Identifiers (DOI) available as Linked Data. DOIs are heavily used in the publishing space to uniquely identify electronic documents (largely scholarly journal articles). CrossRef is a consortium of roughly 3,000 publishers, and is a big player in the academic publishing marketplace.
So practically what this means is that all the places in the scholarly publishing ecosystem where DOIs are present (caveat below), it’s now possible to use the Web to retrieve metadata associated with that electronic document. Say you’ve got a DOI in the database backing your institutional repository:"

The German National Library has been working on a project for automatic subject classification that is expected to go live at the end of this year. This project, called PETRUS, is explained in detail in this article (in German). Part of the Library’s mission is the creation of the German National Bibliography, and to keep pace with the onslaught of (digital) resources more efficiency is needed. The main areas where human intellectual work is supported by machines in the PETRUS project are indexing, classification, metadata extraction and metadata generation."
