Getting context of data provider

Hi,

I am doing remapping of data providers to a new data source. Some of the data providers require a context. The context in the new data source should have the same name and CUID as the old data source, so I would like to determine what context was used in the old data source programmatically and use that to provide the answer to the context parameter when I am remapping to the new data source.

The information for a data provider does not appear to provide the information I need (e.g. http://server:6405/biprws/raylight/v1/documents/1234/dataproviders/DP0)

Is this possible using the RESTful SDK? Is it possible using the Business Objects BI SDK for .NET?

Thanks!
