In order to minimize the load on the Wikipedia API, all requests are cached internally for 12 hours. This means that changes to the English Wikipedia will be available in this service within 12 hours or less if the same entry has been requested before. Classes not requested within the last six hours are always guaranteed to be in sync with the latest version in Wikipedia.
The RDF/XML dump file is updated every 12 hours only.
The class definition text is taken from Wikipedia, the free encyclopedia under a Creative Commons Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0) license. Accordingly, the ontology class definitions are available under the very same license.

rdfs:comment
Since Opener is a disambiguation page in Wikipedia, it should not be used as a class of product or service types.
See http://en.wikipedia.org/wiki/Opener and select the proper meaning.
