JeCARS (Java Extendable Contents And Rights System) is a RESTful webservice which delivers pluggable output formats, e.g. Atom feeds or HTML.
Third party applications can be plugged in.
A JCR (JSR-170) repository (Jackrabbit) is used for storage.
The goal of this project is to create an expandable secure content store along the lines described by JSR 283 supporting an access model, which incorporates both discretionary and mandatory access controls.
The DocWay Published Folder portlet allows you to easily embed Documentum content into your JSR-168 compatible portal. The portlet allows countless users to access files with only a single account. It can be extended to support additional data sources.
