Hoi, The WDQ database is likely to include all the information that you need. It is optimised to be fast. Did you consider to use it? Thanks, GerardM On 15 December 2015 at 22:54, Markus Krötzsch <markus(a)semantic-mediawiki.org

Hoi, In the WDQ database all the data on P and Q values exist. It is stable and it has proven itself over the last years as flexible and very fast. Why build another database that is specific to one goal when another database already exists that largely provides a similar function? A database that can be even run at real time??
