Open Source: When Data Management is Rocket Science
NASA has recently contributed their Object-Oriented Data Technology (OODT) to the Apache group, and the technology has been promoted to a Top-Level Project (TLP) at Apache. As a TLP, OODT will receive project management and resource support from the the Apache foundation. Development for OODT can be traced back to 1998 at NASA’s Jet Propulsion Laboratory to a project started by Daniel Crichton that had the goal of providing a framework to share and search large amounts of data that are distributed across widely separated locations.
OODT has been used in managing data workflows and in the integration of information originating from structured and unstructured information data sources. Using OODT, it is possible to aggregate data from many different sources and create a single interface as a federated query system.
OODT is python-based and consists of the following components:
- Agility
- Catalog and Archive
- Query
OODT is already being used outside of NASA at a number of government agencies and hospitals, like Children’s Hospital in Los Angeles. Crichton added that “defense projects, homeland security, societal benefit programs and water management programs could utilize the technology”.
