Multi-Standard Metadata Retrieval Framework at the Physical Oceanography Distributed Active Archive Center
Abstract
With the vast amount of Earth Science data available, providing the user community with high quality metadata to facilitate information retrieval and exchange is integral to scientific research. The Physical Oceanography Distributed Active Archive Center (PO.DAAC) archives and distributes data products along with metadata pertinent to the physical state of the ocean. As one of the Earth Science data center for NASA, PO.DAAC is expected to work with multiple metadata standards. Since there is no single metadata standard that meets everyone's needs, a web-based framework has been designed and integrated as part of PO.DAAC's scalable Core Data System to enable users to quickly retrieve metadata in the format that they need. Currently, the framework supports the Open Search specification for data discovery, ISO 19115-2, Global Change Master Directory (GCMD) and Federal Geographic Data Committee (FGDC) metadata standards, with new metadata standards still being added. In this talk we will present the architecture behind the framework that makes it possible to support various metadata standards as well as the challenges we encountered.
