Dear Adam, thanks for the pointer. The paper gives an overview of how to design a wiki-based data curation platform for a specific target community. Some of the insights could also apply to Wikidata, while other won't transfer (e.g., you cannot invite the Wikidata community for a

Hi Mingli, thanks, this very interesting, but I think I need a bit more context to understand what you are doing and why. Is your goal to create a library for accessing Wikidata from Clojure (like a Clojure API for Wikidata)? Or is your goal to use logical inference over Wikidata and you

[Wikidata-l] Wikidata RDF export available

2013-08-03 Thread Markus Krötzsch
Hi, I am happy to report that an initial, yet fully functional RDF export for Wikidata is now available. The exports can be created using the wda-export-data.py script of the wda toolkit [1]. This script downloads recent Wikidata database dumps and processes them to create RDF/Turtle files.

Martynas, what you are proposing below is not W3C recommended RDF but an extension of triples to quads. As far as I know, this extension is not compatible yet with existing standards such as SPARQL and OWL. Named graphs work with SPARQL, but are mostly used in another way than you suggest.

In general, policies for notability in Wikidata will be governed by the community of (all) Wikidata editors. On the technical side, we aim to achieve two things: * The system should be able to handle a lot of data. * The interfaces and data access features should minimize the negative impact
