along the lines of supporting REST-ful APIs, is there any way (mapping? etc) to 
support an api like :
GET /api/v1/foo/bar

where:
- /api and /v1 are obviously not content paths
- foo and bar are not sling resources, but might be treated as synthetic 
resources if that is required
- we cannot use Accept header (is it possible to use .json as a default 
extension?)

we are in the process of defining some apis that exist alongside other 
platforms that use apis in this common url format, and it would be really nice 
to use something like jaxrs style tokens for paths that are not sling resource, 
but yet desired to be exposed as urls (I know, this is not the way of sling in 
general…) e.g. @Path("/users/{username}”)

Side note: I haven’t looks into the sling jaxrs support added via 
https://issues.apache.org/jira/browse/SLING-2192, but plan to try it out - does 
it support path tokens/wildcards?

Thanks for any ideas.

Proposal sounds good to me. I would agree to move this to a plugin that gets 
the accept header (is there anything else?) and can update any existing 
selectors/extension/suffix (the PathInfo) parsed already.

   void updatePathInfo(String[] accepts, PathInfo pathInfo);

Notes:
- accept header already parsed (might need to be a special object to include 
weights)
- PathInfo is basically a RequestPathInfo with setters

While the default would not do anything if something was taken from the URL, 
this might still be useful once you support accept headers this way, and 
applications could extend that behaviour. Or simply turn it off (as it is now).

Cheers,
Alex

Hi

Ok, it is not exactly arbitrary logic. Turns out that content types of the style

application/someformat+somesyntax

are pretty common (see [1], [2]). Also when talking about REST-ful APIs I 
expect some application on the other (client) side and this will in general not 
come with a list of content types but with a single one asking for a concrete 
representation.
...

The "structured syntax" is defined in <http://tools.ietf.org/html/rfc6839> -- 
note that you can't simply make up these suffixes (nor media types...).

Best regards, Julian
