Hi,
we are considering a policy for REST API end point result format
versioning and negotiation. The background and considerations are
spelled out in a task and
mw.org page:
https://phabricator.wikimedia.org/T124365
https://www.mediawiki.org/wiki/Talk:API_versioning
Based on the discussion so far, have come up with the following
candidate solution:
1) Clearly advise clients to explicitly request the expected mime type
with an Accept header. Support older mime types (with on-the-fly
transformations) until usage has fallen below a very low percentage,
with an explicit sunset announcement.
2) Always return the latest content type if no explicit Accept header
was specified.
We are interested in hearing your thoughts on this.
Once we have reached rough consensus on the way forward, we intend to
apply the newly minted policy to an evolution of the Parsoid HTML
format, which will move the data-mw attribute to a separate metadata
blob.
