Book Catalog - Python + Google App Engine

This project is to create a Book Catalog web app using GAE and information in an existing GAE data store. The book catalog will be published using the OPDS format, which is an Atom/XML based standard for creating hierarchical book catalogs. There is no HTML/CSS/JS required for this project. The catalog app will be implemented using Google App Engine and Python 2.7. A detailed spec describing the requirements for the project is available. Your job will be to: 1) Review the spec and propose design approach. 2) Update the spec with the design details. 3) Implement the service 4) Provide a test suite to validate that the service works as expected. Experience using Python to develop Google App Engine services using the GAE data store is required. Experience with XML/Atom/OPDS nice to have. This project will implement a minimal slice of the catalog. A follow-on project will expand and flesh-out the catalog. If you are interested, please request and review the spec and data model before bidding.
