The Data Processing Pipeline
A pipeline executes a sequence of plug-able data
processing tasks. The NGDC data processing
pipeline provides a set of pipeline utilities
designed around work queues that run in parallel
to sequentially process data objects. The
pipeline is an open source project hosted in the
Jakarta Commons Sandbox (http//jakarta.apache.org
/commons/sandbox/index.html). Processing steps
are specified as a series of stages in an XML
configuration file.
