Hi Gabriel,

The REST API looks promising - thank you!

Having played around with it a bit, I seem to only be able to get one revision per request. Is that correct, or am I doing something wrong?

this is correct. The requests themselves are quite cheap, and can be parallelized up to rate limit set out in the API documentation.

My project requires every revision and its references from a large number of articles, so that would make a lot of requests. The regular API allows for multiple revisions per request (only with action=query, though).

There is a caveat here in that we currently don't store all revisions for all articles. This means that requests for really old revisions will trigger a more expensive on-demand parse, just as with the action API. Can you say more about the number of articles you are targeting, and how this list is selected? Regarding the selection, I am mainly wondering if you are targeting especially frequently edited articles.

Thanks,

Gabriel

Thanks!

Bertel, another option is to use the REST API:

HTML for a specific revision: https://en.wikipedia.org/api/rest_v1/#!/Page_content/getFormatRevision
Within this HTML, references are marked up like this: https://www.mediawiki.org/wiki/Specs/HTML/1.3.0/Extensions/Cite. Any HTML or XML DOM parser can be used to extract this information.
Hope this helps,

Gabriel

Hi Brad and Gergo,

Thanks for your responses!

@Brad: Yeah, that was also my impression, but I wasn't sure. Seemed strange that the example in the official docs would point to a place where the feature was disabled. Thank you for clearing that up!

@Gergo: I've been looking at action=parse, but as far as I understand it, it is limited to one revision per API request, which makes it quite slow to get a bunch of older revisions from a large number of articles. action=query&prop=revisions&rvprop=content omits the references from the output (just gives the string "{{reflist}}" after "References"). "mvrefs" sounds very promising, though! I will definitely check that out - thank you!

Best,

Bertel

And is there no way of getting references through the API?

There is no nice way, but you can always get the HTML (or the parse tree, depending on whether you want parsed or raw refs) and process it; references are not hard to extract. For the wikitext version, there is a python tool: https://github.com/mediawiki-utilities/python-mwrefs
