Scientific publisher Nature Publishing Group (NPG), UK, has announced that its Linked Data Platform now hosts more than 270 million Resource Description Framework (RDF) statements. It has been expanded more than ten times, in a growing number of datasets. These datasets have been created under the Creative Commons Zero (CC0) waiver, which permits maximal use/reuse of this data. The data is now being updated in real-time and new triples are being added to the datasets as articles are published on nature.com.
Available at http://data.nature.com, the platform now contains bibliographic metadata for all NPG titles, including Scientific American back to 1845, and NPG's academic journals published on behalf of its society partners. NPG's Linked Data Platform now includes citation metadata for all published article references. The NPG subject ontology is also significantly expanded.
The new release expands the platform to include additional RDF statements of bibliographic, citation, data citation and ontology metadata, which are organised into 12 datasets - an increase from the 8 datasets previously available. Full snapshots of this data release are now available for download, either by individual dataset or as a complete package, for registered users at http://developers.nature.com.
NPG's platform allows for easy querying, exploration and extraction of data and relationships about articles, contributors, citations, publications, and subjects. Users can run web-standard SPARQL Protocol and RDF Query Language (SPARQL) queries to obtain and manipulate data stored as RDF. The platform uses standard vocabularies such as Dublin Core, FOAF, PRISM, BIBO and OWL, and the data is integrated with existing public datasets including CrossRef and PubMed. The platform originally launched in April 2012.
