		<pub:abstract><![CDATA[The Atmospheric Composition Processing System
(ACPS) evolved from the heritage processing systems
currently processing ozone data at NASA, Goddard
Space Flight Center. The ACPS includes complete
provenance tracking of the various artifacts related to
data processing. These include the data transformation
algorithms and all data in the system, both inputs from
external sources and data produced within the system.
Other artifacts include the hardware and software of the
processing framework, the source instruments and satellites,
scientific literature and documentation, and people
and organizations. The origin of any data or algorithms
is recorded and the entire history of the processing chains
are stored such that a researcher can understand the entire
data flow. Provenance is captured in a form suitable
for the system to provide basic scientific reproducibility
of any data product it distributes even in cases where the
physical data products themselves have been deleted due
to space constraints. This paper will discuss the identification
of provenance artifacts in the system and web
services for communicating metadata about those provenance
artifacts.]]></pub:abstract>
