REST solutions

I've tried with varying degrees of success to express a certain thesis; Aristotle Pagaltzis nails it on rest-discuss:

... Resources derive from the solution domain, not part of the problem domain. Creating resources for concepts that the solution requires is how modeling works in REST terms; they don’t have to derive from any aspect of the problem in order to be justified.

Vish gets it. The problem is that you've got a legacy database and network access to it (SOAP/W*S) sucks (no uniform interface, no caching, etc). The solution: create new web resources that interface easily and cleanly with client-side javascript. These resources don't have to map one-to-one to any particular object or method in your database or framework.

Interestingly, the quote occurs in a thread about "query resources", a notion I've blogged and which remains difficult to swallow for GIS folks.
