Yes, these two. > - Which JSON representations do the API and the XML dump provide? Will > they do so in the future? The XML dump provides the internal representations (since it's a dump of the raw page content). The API uses the external representation. This is pretty much dictated by the nature of the dumps and the API, so it will stay that way. However, we plan to add more types of dumps, including: * a plain JSON dump (using the external representation) * an RDF/XML dump It's not sure yet when or even if we'll provide these, but we are considering it. > - Are the API and XML dump representations stable? Or should we expect > some changes? The internal representation is unstable and subject to changes without notice. In fact, it may even change to something other than JSON. I don't think it's even documented anywhere outside the source code. The external representation is pretty stable, though not final yet. We will definitely make additions to it, and some (hopefully minor) structural changes may be necessary. We'll try to stay largely backwards compatible, but can't promise full stability yet. Also, the external representation uses the API framework for generating the actual JSON, and may be subject to changes imposed by that framework. Unfortunately, this means that there are currently no dumps with a reliable representation of our data. You need to a) use the API or b) use the unstable internal JSON or c) wait for "real" data dumps. -- daniel _______________________________________________ Wikidata-l mailing list Wikidata-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata-l
