Extend PAIA to support services not related to documents

[nichtich]

Libraries may provides services not related to a document, such as reservation of a cabin. PAIA could easily be extended to support such services, as long as they can be requested/reserved/canceled. For instance one could use edition and item URI to refer to cabins or other services. Possible problems:

• naming of parameters is aimed at document services
• a patron may not want to mix document services and other services (e.g for the read_items scope)

A possible solution would be to introduce a new method "services" and to extend the methods "renew", "request", and "cancel" for document services and other services.

I asked about typical service types in libraries at libraries.stackexchange. Adrian provided a list which I discussed in my blog (in German).

The fees method already supports services not related to documents. The methods request, renew, and cancel should be extended to support non-document services. Additional methods such as services may be added to list non-document services in a patron account. There should also be a method to list possible service types what a patron is allowed to request from the providing institution.
