[oslc-core] Signing up to look at service discovery

[Arthur Ryman]

Steve/David,

FYI, Roy Fielding asserts that one of the defining principles of REST API 
is that all interactions should be driven from links present in the 
representation of the resource, i.e. given a resource URL it should be 
possible to navigate from it to the service URL just by following links. 
[1] He has a lot of extreme opinions, but I like this one.

In the Estimation spec, every resource instance (Project, Scenario, 
Estimate, Baseline,..)  has a link to its containing List resource (e.g. 
ProjectList, ..), which in term has a link to its Service resource. The 
Service resource links to all the List resources. Each List resource links 
to all of its member instance resource. Therefore, if you get any of these 
resources you can navigate to any other resource within the service.

Hi Dave,

I spoke up at the end of last call but not sure you heard.  I am offering 
to author some content around service discovery and description.  In 
addition, I'll look into what some refer to as "inverse discovery", given 
a resource URL, how to get the service description for that service 
provider.    I know a few domains have expressed a need for this.

Let me know if you've already got this covered.

Thanks,
