[oslc-core] Questions/remarks about the delegated UI for resource selection

[Thunissen Marc]

Hello,

 

I have a few remarks about the delegated UI for the resource selection:

 

1.       The specs are unclear about the possibility to select one or more resources.
The explanations are "allow a user to pick a resource" (one resource), but the example show a response with two resources.
My feeling about that is that the UI consumer should be able to choose the preferred behavior: single or multiple selection.
Can we imagine an option in the UI URI, such as "oslc.options=singleSelection" or "oslc.options=multipleSelection" ?

 

2.       As a UI consumer, I also have a need to restrict the resource selection.
I would like to allow the user to select an asset, but only for a specific asset type.
By instance we are in a workflow to create a request for tender and I want to allow the user to select a template for the document to create.
I could be useful to allow the "oslc.where" in the UI URI.
Something like and oslc.where=dcterms:type="Request for tender template" could be a solution.

 

3.       A common design pattern is to build the UI on top of the API.
It could be interesting to be able to create a generic UI layer using metadata coming from the API to build the creation and selection HTML forms.
We can use the resource shape, but I cannot find a kind of "display name" for the properties to create the form labels (and of course we need to care about the localization).



4.       I have some oslc resources for which some properties must be specified when creating a new resource but cannot be changed later.
I am not sure how to declare this in the shape.
Should I have to write "oslc:readOnly=true", "oslc:occurs=http://open-service.net/ns/core#Exactly-one" and no "oslc:defaultValue".
But there are also some resources, such as the "dc:identifier", that can neither be set at creation time nor changed later.
How can I mark the difference in the shape (still trying create the UI automatically) ?

 

Best regards,

 

Marc
