Transportation, Aviation,
and Aerospace Track Description
This track focuses on utilization
of ISO/IEC 11179 and other registries for managing a wide variety of data. The
data may be included in information systems or may be the data products of
orbiting satellites. The track covers both technical issues about data and data
registries as well as organizational issues for managing the development of
standard data.
Enormous amounts of data are
created by national and international aeronautics and space missions. The data
products would be of limited value without appropriate descriptive information.
ISO/IEC 11179 attributes are useful for documenting data products. Several
projects are actively developing and using registries. The Planetary Data
System (PDS) has an archive collected from over 30 years of solar system
exploration. The archive is geographically distributed to keep the data in the
hands of the scientific experts and to promote closer ties with the mission
instrument teams. An on-line distributed search and retrieval system is under
development. The first delivery of this system will use ISO/IEC 11179 based
metadata descriptors, XML documents, and the wealth of metadata in the archive
to locate data sets and supporting resources across the discipline nodes of the
PDS.
NASA/JPL is pursuing an Enterprise
Data Architecture task that is developing an integrated
information architecture to enable JPL to meet its strategic goals. It promises
to provide institutional data management services that promote interoperability
between distributed data resources and leverage existing institutional services
and enterprise applications. The goal is to enable not only data management,
but information and knowledge management. A key component of this architecture
is the metadata service. The purpose of the metadata service is to provide a
series of registries that allow for the management of enterprise data
dictionaries, data elements, and system resource descriptions. The metadata
service makes extensive use of the ISO/IEC 11179 specifications. Special
emphasis has been given to providing semantic interoperability through the
concept of an enterprise data element registry.
Projects are also underway in the
aerospace community to make 11179 registries accessible through LDAP. This
would provide another means for obtaining standard data and descriptions of
data products. A presentation will describe work that is underway.
The
The Federal Aviation Agency is
working with industry partners to standardize data. This track will provide an
overview and discussion of the FAA Data Registry. This includes a demonstration
of the registry and a discussion on the data standardization and approval (i.e.
configuration control board) process the FAA has developed. The presentations
also cover how the data registry fits into the overall data management program
that the FAA is implementing.
