There is again no reason why you cannot define new HTTP methods if you
find that they are necessary. See

Yes, the APP has made a great deal of forward progress in defining a
reasonably simple HTTP based API. A great deal of APP work has gone
into defining a schema for describing ‘collections’ & ‘workspaces’ of
weblogs, little of which has any application for SRU, so I’m not sure
that adopting the APP would be necessarily worthwhile (SRU could
probably use about 1/4 of the total text of the latest draft).
This approach is gaining rapid traction. Google’s has adopted it for
their Gdata set of APIs, Amazon has adopted it for S3 (though they
have a SOAP translation), and no doubt many others.
