Subject Re: REST plugin URL syntax
Date Mon, 16 Jun 2008 20:27:15 GMT
Thanks for the feedback.

I actually disagree regarding whether my url syntax is restful.

Have you read the O'Reilly book: "RESTful Web Services" by Leonard
Richardson; Sam Ruby?

If not please take a look (you can probably see sample chapters on
Safari if you don't have an account).
Specifically in section 5.5.1 Encode Heirarchy into Path Variables
where examples like this are provided:

In fact the samples the entire book is based on all rely on hierarchy.
Hierarchy is *very* relevant to my problem domain and is something
that a RESTful interface *should* be able to support. Do you not agree
a news website is hierarchical? The web is hierarchical in nature.
REST is supposed to be the language of the web...

If the REST plugin can't support this hierarchical model I'd say it is
fundamentally flawed. I'm happy to help rectify this but to say that
this approach just isn't REST is simply not true.

Can anybody suggest where I would start in an attempt to implement
this hierarchical model? Or do I need to start looking for a
replacement for the Struts2 REST plugin?

Thanks for your time.
