A Case for Data and Service Fusions

Abstract:

In this distributed, data-intensive era, developing any solution that requires multi-disciplinary data and service requires careful review of interfaces with data and service providers. Information is stored in many different locations and data services are distributed across the Internet. In design and development of mash-up heterogeneous data systems, the challenge is not entirely technological; it is our ability to document the external interface specifications and to create a coherent environment for our users. While is impressive to present a complex web of data, the true measure of our success is in the quality of the data we are serving, the throughput of our creation, and user experience. The presentation presents two current funded NASA projects that require integration of heterogeneous data and service that reside in different locations. The NASA Sea Level Change Portal is designed a “one-stop” source for current sea level change information. Behind this portal is an architecture that integrates data and services from various sources, which includes PI-generated products, satellite products from the DAACs, and metadata from ESDIS Common Metadata Repository (CMR) and other sources, and services reside in the data centers, universities, and ESDIS. The recently funded Distributed Oceanographic Matchup Service (DOMS) project is a project under the NASA Advance Information Technology (AIST) program. DOMS will integrate with satellite products managed by NASA Physical Oceanography Distributed Active Archive Center (PO.DAAC) and three different in-situ projects that are located in difference parts of the U.S. These projects are good examples of delivering content-rich solutions through mash-up of heterogeneous data and systems.
