OpenCMIS InMemory Repository
This repository is obviously not intended for production use!
The OpenCMIS In-Memory Repository is an implementation of a CMIS repository
that holds content and metadata in memory. Therefore, all data stored in
the repository is lost after each restart. This implementation has two main
- Provide a fast backend for testing purposes without any additional
dependencies or configuration.
- Provide a sample implementation for the server interface of OpenCMIS.
The code is unstable and under development. Expect any interface to change at any time.
The following features are implemented:
- Type System and Repository Service
- Object Service
Not supported are currently:
Build and Deploy the Repository
- Follow this guide: How to build OpenCMIS
- A ready-to-use WAR file should now exist in
- Deploy the WAR file to your favorite servlet engine.

Configure the Repository
The CMIS specification does not currently provide support for creating a
repository or administrative capabilities such as the creation of type
The in-memory repository therefore provides settings that allows the server
to bootstrap itself, so that on successful startup, the server is in a
usable state. These settings include the repository id, its type
definitions and an initial folder/document data set.
The types to be made available must be provided in a Java class as code. By
default, the class
is provided. You can take this as an example if you want to provide your
own custom types. Such a class must implement the
org.apache.chemistry.opencmis.inmemory.TypeCreator interface which
consists of a single method that returns a list of
objects. This method will be called once during startup.
Some clients just support read-only access. The in-memory repository
supports such clients by providing the possibility to fill a repository on
start-up with data (folders and documents). The folder and document types
to be used can be configured and also the number of documents and folders
that are created. Those configuration parameters start with the prefix
Bootstrap settings are set in the repository.properties file
