The manuals of this Orbeon Persistence Layer can be found here:
This Orbeon Persistence Layer is an implementation of REST Services on the top of GemStone/S (http://www.gemtalksystems.com) to store Orbeon Forms (http://www.orbeon.com) natively in GemStone/S Database (a NON SQL database).
To install GemStone/S:
The Documentation in this here is about the REST Services implmenentation in GemStone/S and is NOT an official documentation of Orbeon Persistence Layer. The official Documentation of Orbeon Persistence Layer can be found here.
The following diagrams are just to get a general idea how to implement an Orbeon Persistence Layer. There are NOT detailed implementation diagrams. The purpose is to list the services that Orbeon call for each functionallit, not to show the internals of the GemStone/S implmentation (for this you can download the code) :)
The following Diagrams are grouped by Orbeon functionality.
The following link show all services that MUST be implemented for a complete Orbeon Persistence Layer. You will notice that various services can be implemented as one because of it's service path. But at implementation level we choose to split them by funcionality not by path.
Persistence Layer Configuration Options
