Welcome to Apache OODT http://oodt.apache.org/

OODT is a grid middleware framework used on a number of successful projects at NASA's Jet Propulsion Laboratory/California Institute of Technology, and many other research institutions and universities, specifically those part of the:

  • National Cancer Institute‘s (NCI’s) Early Detection Research Network (EDRN) project - over 40+ institutions all performing research into discovering biomarkers which are early indicators of disease.
  • NASA‘s Planetary Data System (PDS) - NASA’s planetary data archive, a repository and registry for all planetary data collected over the past 30+ years.
  • Various Earth Science data processing missions, including Seawinds/QuickSCAT, the Orbiting Carbon Observatory, the NPP Sounder PEATE project, and the Soil Moisture Active Passive (SMAP) mission.

OODT is a Top Level project of the Apache Software Foundation http://www.apache.org/.

Getting Started

OODT is primarily written in Java, with some components available in Python. It requires Java 5 and uses the Maven 2 http://maven.apache.org/ build system. To build the Java components of OODT, use the following command in this directory:

mvn clean install

For the Python components, see the “agility” subdirectory.


To contribute a patch, follow these instructions (note that installing Hub is not strictly required, but is recommended).

0. Download and install hub.github.com
1. File JIRA issue for your fix at https://issues.apache.org/jira/browse/OODT
- you will get issue id OODT-xxx where xxx is the issue ID.
2. git clone http://github.com/apache/oodt.git
3. cd oodt
4. git checkout -b OODT-xxx
5. edit files
6. git status (make sure it shows what files you expected to edit)
7. git add <files>
8. git commit -m “fix for OODT-xxx contributed by <your username>”
9. git fork
10. git push -u <your git username> OODT-xxx
11. git pull-request

Apache OODT includes a number of subcomponents with separate copyright notices and license terms. Your use of these subcomponents is subject to the terms and conditions of the licenses listed in the LICENSE.txt file.

Export control

This distribution includes cryptographic software. The country in which you currently reside may have restrictions on the import, possession, use, and/or re-export to another country, of encryption software. BEFORE using any encryption software, please check your country's laws, regulations and policies concerning the import, possession, or use, and re-export of encryption software, to see if this is permitted. See http://www.wassenaar.org/ for more information.

The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has classified this software as Export Commodity Control Number (ECCN) 5D002.C.1, which includes information security software using or performing cryptographic functions with asymmetric algorithms. The form and manner of this Apache Software Foundation distribution makes it eligible for export under the License Exception ENC Technology Software Unrestricted (TSU) exception (see the BIS Export Administration Regulations, Section 740.13) for both object code and source code.

The following provides more details on the included cryptographic software:

Apache OODT uses Apache Tika which uses the Bouncy Castle generic
encryption libraries for extracting text content and metadata from
encrypted PDF files.  See http://www.bouncycastle.org/ for more details on
Bouncy Castle.


You can build a local copy of the OODT documentation including JavaDocs using the following Maven 2 command in the OODT source directory:

mvn site

You can then open the OODT Documentation in a web browser:


Note: all OODT source files are encoded with UTF-8. You must set your MAVEN_OPTS environment variable to include “-Dfile.encoding=UTF-8” in order to properly generate the web site and other artifacts from source.

Note: generating the documentation requires enormous amounts of memory. More than likely you'll need to add to the MAVEN_OPTS environment variable in order to set the Java heap maximum size with “-Xmx512m” or larger before attempting to run “mvn site”.

Mailing Lists

Discussion about OODT takes place on the following mailing lists:

dev@oodt.apache.org    - About using OODT and developing OODT

Notification on all code changes are sent to the following mailing list:


The mailing lists are open to anyone and publicly archived.

You can subscribe the mailing lists by sending a message to -subscribe@oodt.apache.org (for example dev-subscribe@oodt...). To unsubscribe, send a message to -unsubscribe@oodt.apache.org. For more instructions, send a message to -help@oodt.apache.org.
