Apache Chemistry provides open source implementations of the
 [Content Management Interoperability Services (CMIS)](http://docs.oasis-open.org/cmis/CMIS/v1.0/cmis-spec-v1.0.html)
 specification.  
See the [What is CMIS?](project/cmis.html) page for more information about the standard.

The project currently consists of the following sub-projects:

* [OpenCMIS](java/opencmis.html) - CMIS client and server libraries for Java 
* [cmislib](python/cmislib.html) - CMIS client library for Python
* [phpclient](php/phpclient.html) - CMIS client library for PHP
* [DotCMIS](dotnet/dotcmis.html) - CMIS client library for .NET

Chemistry mailing list for questions and contributions:
[dev@chemistry.apache.org](http://mail-archives.apache.org/mod_mbox/chemistry-dev/)

*Important time-saving note for chemists:* the Apache Chemistry project has
nothing to do with chemistry or chemicals! The name comes from the
inclusion of the C.M.I.S. letters, "CheMIStry".

### CMIS and Apache Chemistry in Action

[CMIS and Apache Chemistry in Action](http://www.manning.com/mueller/) is a comprehensive guide to the CMIS standard and related ECM concepts. In it, you'll tackle hands-on examples for building applications on CMIS repositories from both the client and the server sides. You'll find working examples using the Apache Chemistry APIs for Java, Python, C#, Objective-C, and PHP, but you can use the techniques you'll learn in this book to work with CMIS repositories using any language that can speak HTTP - including JavaScript.
