I am happy to announce that the Office Business Applications Reference Application Pack for Loan Origination Systems (OR-LOS)!
See the MSDN OR-LOS Page at: http://msdn.microsoft.com/Architecture/ORLOS
On the OR-LOS page on MSDN you will find a set of technical resources to guide the development of a new class of business applications called "Office Business Applications" (OBAs). These resources include an OBA reference architecture framework coupled with a consumer wholesale lending banking scenario. Below are links to a series of whitepapers outlining details of the reference solution that illustrate both the end user experience as well as the development model.
