[oslc-core] Behavior of oslc.where and oslc.sort if resources are not managed by the service provider

[Dragos Cojocari]

Hey Arthur,

thanks for the reply.  The first two resources both have 
oslc:shortTitle="Some defect" so I assume both will be included. But what 
if the 3rd one, the one not managed by the service provider also has 
oslc:shortTitle="Some defect"? The service provider doesn't know that so 
it won't include that in the result. In my opinion that is incorrect, 
since the result set is not full. I think that reporting an error if the 
service provider cannot verify the filter/sort for all the collection 
members would be more rigorous. What do you think?

Regards,
        Dragos

Dragos,

BTW, the query result is just the first resource since it matches 
oslc:shortTitle="Some defect"

Hey everyone, 

and a Happy new year. 

I'd like to understand what is the defined behaviour if a query specifies 
in its where/orderBy clause and the collection of resources contains 
resources not managed by the service provider and the serviceprovider 
cannot filter/sort them. What should the provider do: 
- reject the response with an error 
- include only the resources for which the filter/sort can be calculated 
- undefined 

Example data: 




So for the data above what is the expected result for the following query: 

 
http://<server>:<post>/defects?oslc.select=*&oslc.where=oslc:shortTitle="Some 

defect" 

Regards, 
        Dragos
