The Profile Service describes and locates resources using metadata descriptions. These descriptions, called profiles, tell of a resource's inception, composition, and location using a mix of Dublin Core and ISO-11179 metadata as well as URIs for locations. The Profile Service catalogs metadata descriptions and provides creating, updating, and querying capabilities.

This component provides a way to express queries in a generic manner. Its centerpiece is a class called XMLQuery that uses boolean postfix expressions to capture the domain, range, and constraint of a query, regardless of the source of the query (SQL, keyword query, etc.). It can also encapsulate the results of a query. It's used by many other components as the standard way to pass a query and its results between servers, clients, nodes, and other components.

The Product Service provides access to data products. Products can be scientific datasets, images, documents, or anything with an electronic representation. The Product Service accepts standard query expressions (see the Query Expression component) and returns zero or more matching products. In addition, the product service can transform products from proprietary formats and into Internet standard formats or run other transformations, all without impacting local stores or operations.

An XML-configured DBMS-based Product and Profile meant to easily sit on top of Web-Grid and other Product and Profile server contexts for rapid deployment and integration.
