Apache Chemistry provides open source implementations of the [Content Management Interoperability Services (CMIS)][cmis] specification.  
See the [What is CMIS?](project/cmis.html) page for more information about the standard.

*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

<div style="float:left; padding-right:10px;"><a href="https://www.manning.com/mueller/"><img src="/images/book/apache-chemistry-in-action.png" alt="CMIS and Apache Chemistry in Action"/></a></div>

[CMIS and Apache Chemistry in Action](https://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.
