  • Mercury is a federated metadata harvesting, data discovery and access tool based on both open source packages and custom developed software. Though originally developed for NASA, the Mercury development consortium now includes funding from NASA, USGS, and DOE. Mercury supports the reuse of metadata by enabling searching across a range of metadata specification and standards including XML, Z39.50, FGDC, Dublin-Core, Darwin-Core, EML, and ISO-19115. Mercury provides a single portal to information contained in distributed data management systems. It collects metadata and key data from contributing project servers distributed around the world and builds a centralized index. The Mercury search interfacesmore » then allow the users to perform simple, fielded, spatial and temporal searches across these metadata sources. One of the major goals of the recent redesign of Mercury was to improve the software reusability across the 12 projects which currently fund the continuing development of Mercury. These projects span a range of land, atmosphere, and ocean ecological communities and have a number of common needs for metadata searches, but they also have a number of needs specific to one or a few projects. To balance these common and project-specific needs, Mercury's architecture has three major reusable components; a harvester engine, an indexing system and a user interface component. The harvester engine is responsible for harvesting metadata records from various distributed servers around the USA and around the world. The harvester software was packaged in such a way that all the Mercury projects will use the same harvester scripts but each project will be driven by a set of project specific configuration files. The harvested files are structured metadata records that are indexed against the search library API consistently, so that it can render various search capabilities such as simple, fielded, spatial and temporal. This backend component is supported by a very flexible, easy to use Graphical User Interface which is driven by cascading style sheets, which make it even simpler for reusable design implementation. The new Mercury system is based on a Service Oriented Architecture and effectively reuses components for various services such as Thesaurus Service, Gazetteer Web Service and UDDI Directory Services. The software also provides various search services including: RSS, Geo-RSS, OpenSearch, Web Services and Portlets, integrated shopping cart to order datasets from various data centers (ORNL DAAC, NSIDC) and integrated visualization tools. Other features include: Filtering and dynamic sorting of search results, book- markable search results, save, retrieve, and modify search criteria.« less
  • The Carbon Dioxide Information Analysis Center (CDIAC) compiles and provides information to help international researchers, policymakers, and educators evaluate complex environmental issues associated with elevated levels of atmospheric carbon dioxide (CO{sub 2}) and other trace gases, including potential climate change. CDIAC is located within the Environmental Sciences Division of Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee and is line funded by the U. S. Department of Energy`s (DOE) Global Change Research Program (GCRP). CDIAC is an information analysis center (IAC). In operation since 1982, CDIAC identifies sources of primary data at national and international levels; obtains, archives, evaluatesmore » and distributes data and computer models; fully documents select data sets and computer models and offers them as numeric data packages (NDPs) and computer model packages (CMPs); distributes data and computer models on a variety of magnetic and electronic medias including 9-track magnetic tapes; IBM-formatted floppy diskettes; CD-ROM; and over Internet, Omnet, and Bitnet electronic networks; develops derived, often multidisciplinary data products useful for carbon cycle and climate-change research; distributes reports pertinent to greenhouse effect and climate change issues; produces the newsletter, CDIAC Communications; and in general acts as the information focus for the GCRPs research projects. Since its inception, CDIAC has responded to thousands of requests for information, and since 1985 has distributed more than 70,000 reports, NDPs and CMPs to 97 countries worldwide.« less
