Mercury is a Web-based system to search for metadata and retrieve
associated data. Mercury incorporates a number of important features.
Mercury
- Invokes a new paradigm for managing
dynamic distributed scientific data and metadata
- Provide a single portal to information contained in disparate data management systems
- Provide free text, fielded, spatial, and temporal search capabilities
- Puts control in the hands of
investigators or other data providers
- Has a very light touch (i.e., is
inexpensive to implement)
- Is implemented using Internet
standards, including XML
- Supports international metadata
standards, including FGDC, Dublin-Core, EML, ISO-19115
- Is compatible with Internet search
engines
- Is based on a combination of open
source tools and ORNL developed software

The new Mercury system is
based on open source and Service Oriented Architecture and provides multiple search services including: RSS, Geo-RSS, OpenSearch, Web Services and JSR-168 Portlets.

Mercury has the unique capability to extract, or harvest,
metadata from HTML pages or XML files located anywhere on the
Internet. Participating in Mercury is easy for data
providers. No special software is needed by the data
provider, only a Web server on which to post files.
Mercury provides a single portal to information contained in disparate 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 interfaces then allow the users to perform simple, fielded, spatial and temporal searches across these metadata sources. Mercury supports various metadata standards including XML, Z39.50, FGDC, Dublin-Core, Darwin-Core, EML, and ISO-19115.
The Mercury system is based on a Service Oriented Architecture and supports various services such as Thesaurus Service, Gazetteer Web Service and UDDI Directory Services. This system also provides various search services including: RSS, Geo-RSS, OpenSearch, Web Services and JSR-168 Portlets. Other features include: Filtering and dynamic sorting of search results, book-markable search results, save, retrieve, and modify search criteria.
