## About Expere Document Services

Expere Document Services (EDS) allows users to create a web service portal that will allow integrating partners and customers the ability to submit xml data in order to produce documents in the form of a PDF. The EDS architecture is a three tier system consisting of a optional web service, transaction queue, processing service, document engine, and transactional storage.

## About SecuritySessionSvc

The SecuritySessionSvc allows users to connect their loan origination service to the DocViewer interface. The DocViewer allows users to finish collecting data for a desired transaction, then displays a visual representation of the final document or set of documents (known as packages).
