Description
The lattice gauge theory community produces large volumes of
data. Because the data produced by completed computations form the
basis for future work, the maintenance of archives of existing data
and metadata describing the provenance, generation parameters, and
derived characteristics of that data is essential not only as a
reference, but also as a basis for future work. Development of these
archives according to uniform standards both in the data and metadata
formats provided and in the software interfaces to the component
services could greatly simplify collaborations between institutions
and enable the dissemination of meaningful results.
This paper describes the progress made in the development of a set of
such archives at the Fermilab lattice QCD facility. We are
coordinating the development of the interfaces to these facilities
and the formats of the data and metadata they provide with the efforts
of the international lattice data grid (ILDG) metadata and middleware
working groups, whose goals are to develop standard formats for
lattice QCD data and metadata and a uniform interface to archive
facilities that store them. Services under development include those
commonly associate with data grids: a service registry, a metadata
database, a replica catalog, and an interface to a mass storage
system. All services provide GSI authenticated web service interfaces
following modern standards, including WSDL and SOAP, and accept and
provide data and metadata following recent XML based formats proposed
by the ILDG metadata working group.
