Does “LINQ to DQL” exist?

Question

If LINQ-to-SQL overcomes the object-relational impedance mismatch of a .NET application talking to a SQL Server database...

If I want to build a .NET MVC UI, where my model queries a Documentum CMS database...

Is there a LINQ to DQL (Documentum Query Language) library ? ...

... that will help me overcome the object-relational impedance mismatch of talking to Documentum?

I am working on a project where a .NET web-application that pulls content from a Documentum 6.5 content management system is going to be re-built.

The .NET web-application will be .NET MVC and will be built as a self-standing application.

The team building the .NET application should ideally not have to learn the intricacies of Documentum and for an interface build, and a Documentum learning course is probably overkill and would probably exceed the project timeframe by 300%-400%.

So before I start trying to start calling up EMC, has anyone heard of anything like this? I thought the idea of "LINQ to DQL" would be a logical step. I have never worked with Documentum although I have worked with ECM before and understand the concepts. I know that Documentum is traditionally *nix based, Java, Apache (Tomcat) but that shouldn't stop me querying it from a .NET application, similar to SQL. And if we take it that far, might as well look at LINQ for the querying mechanism...?

It doesn't seem to exist, but you could implement your own Linq to DQL provider...

Check out this excellent series on how to implement an IQueryable provider

I used this tutorial to create a simple Linq to WMI provider (just for training, since a much better one already exists)
