We have a rich domain model that is used across the application (ASP.NETMVC2). Some of our views are Master Detail Views , basically paginated summary reports. We navigate to the the Detail View from these summary views.
The summary views is currently using a list of full-blown domain entities , and is therefore not very performant. We want to re-write the query in the summary report to use report queries / projection queries to retrieve only the data that is needed - now we would like to be able to re-use the domain model rather than introduce a new DTO. As this will save us the trouble of refactoring the summary views to use the new DTO. The partial objects are read-only and will not be persisted.
