Peter,

you could use URLs like the follwoing

http://www.example.org/persons 

    to address the list of all persons

http://www.example.org/persons/Joe

    to address Joe

http://www.example.org/persons/Joe/Name

    to address Joe's name

http://www.example.org/persons/Joe/Age

    to address Joe's age

etc.

Content negotiation between server and client could return the various
'entities' in diverse formats, among them "Joe" for

http://www.example.org/persons/Joe/Name

Does that help?
