OSLC & LDP: Query Capabilities, Creation Factories & location of Dialogs

As we move OSLC 3 to be based on LDP, I
presume Query Capabilities and Creation Factories will be replaced by capabilities
from LDP.

As I'm starting to draft the Automation
v3 spec, I've come to the place where I need to be able to refer to the
definition of the headless query/selection and creation capabilities.

This also raises the question: are we
keeping the existing oslc:ServiceProvider and oslc:Service resources? I
see no reason not to.

So my expectation of how this would
go is: 

1. An oslc:ServiceProvider: 

        a)
which is possibly discoverable from an oslc:ServiceProviderCatalog 

        b)
would contain one or more oslc:Service resources 

2. These oslc:Service resources: 

        a)
would each identify which OSLC domain they operate in using their 

        oslc:usage
property 

         
      i) (I believe this can also exist at the oslc:ServiceProvider
level) 

        b)
Link to LDP containers for each of the resource types they work with 

         
      i) (They may have more than one container
for each resource type, e.g. 

         
      Automation Requests ready for execution, and
Automation Request 

         
      templates) 

        c)
Maybe, they would still contain the links to the Creation & Selection

        dialogs
(i.e. in the same place as v2) 

        d)
(for providers wanting to be compatible with v2:) would contain v2 

        Creation
Factories and Query Capabilities 

3. Those LDP containers: 

        a)
would provide LDP's querying mechanism. (Is there such a thing? I 

        can't
find it.) replacing v2's Query Capabilities 

        b)
where appropriate, would provide the creation capability (replacing 

        v2's
Creation Factories) 

        c)
Maybe, it might be appropriate to link from the container to the 

        creation
& selection dialogs for the resources in that container. So 

        (for
dialogs that are specific to a single LDP container - not all will 

        be)
all the operations for that container are linked from the container 

        itself.
However, compatibility with v2 would require that the dialogs 

        are
linked from the oslc:Service. 

In particular, right now I need to know:

- Is 3a correct, or will we be keeping
Query Capabilities?

I think 3c is also an important point
to decide on.

Thanks,

Martin
