Welcome to Apache OODT <>
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+
* 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
Getting Started
OODT is primarily written in Java, with some components available in Python.
It requires Java 5 and uses the Maven 2 <> build
system. To build the Java components of OODT, use the following command in
this directory:
mvn install
For the Python components, see the "agility" subdirectory.

Apache OODT includes a number of subcomponents with separate copyright

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
<> 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 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".
