Delegation Dialog issues

Not much here.

1. Delegated Dialog Discovery

OSLC2 uses an oslc:selectionDialog of
an oslc:Service resource that has an inlined oslc:Dialog element that has
an oslc:dialog property whose value is the URI of the selection dialog.
Similar for creationDialog. OSLC3 uses Link and Prefer headers on an LDPC
to get similar information. 2.0/3.0 Discovery compatibility re-introduces
the ServiceProviderCatalog, ServiceProvider and Service resources with
the properties referenced in dialog discovery. So these just need to be
summarized and reference in the delegated dialog specification. This provides
3 ways to get the delegated dialog in OSLC3.

2. Dialog Prefill

For dialog prefill, neither OSLC2 or
OSLC3 specifies specifically what formats are required for the entity request
body that contains the representation of the resource the server should
use to prefill the dialog. We can assume its the same resource representations
and media-types that a client could GET on the created resource. That's
addressed in the core overview document in resource representations, but
could be mentioned in the dialog prefill section too.

3. Dialog message protocols

OSLC2 supported postMessage and windowName
protocols for interaction between delegated dialogs and the client window
in which they are hosted in order for the dialog to communicate the selection
or creation results back to the client application. 

Resolution: I think we can safely assume
that modern browsers now support HTML5 postMessage and can drop the windowName
protocol.
