... held a workshop on Coping with increasing Demands on Government Environmental Data Centers. The objectives of the workshop were to consider technological solutions that could enhance Me ability of users to find, interpret, and analyze information held in environmental data centers and that could help data centers collect, store, share, manage, and distribute large volumes of data.

... Recommendation: With their user communities, data centers should accelerate work toward standardizing and making formats more transparent for data and metadata and thereby improve distribution and interoperability between data centers, between data centers and users, and between users. Metadata formatted in XML would assure that recipients would be able to parse data automaffcaBy and feed them directly to their applications.

... In addition, data centers and their sponsoring agencies should enable direct random on-line access through networks and provide support for remote queries on databases. MORE SOPHISTICATED DATABASE TECHNOLOGIES Files are a reasonable way to organize data when the physical storage medium is tape; however, disk storage permits data to be organized ~ much more flexible databases.

... Data centers have spent considerable effort preserving metadata by routinely documenting information on data Lineage, such as the source data, transformation processes, and quality assurance information, of their datasets. Open access to summaries of the dataset assembly processes and lineage has contributed significantly to ensuring user confidence in data product quality.

... Finally, while most data centers are managed as centralized organizations, a federated distributed system would formalize current user practices of obtaining some scientific products from colleagues and data projects instead of Tom data centers and could help reduce infias~cructure and management costs for data centers. Recommendation: Data centers should adopt commodity hardware and commercial and open-source software solutions to the widest extent possible and concentrate their own efforts on problems that are unique to environmental data management.

... Without question, data centers should not rely solely on technology without continuing to invest in He scientific and human elements of data management and data center operations.
