Keyword based indexing and searching over storage resource broker

2007
Conference Papers

Abstract

A keyword based metadata indexing and searching facility for Storage Resource Broker (SRB) is presented here. SRB is a popular data grid based storage system that provides means to store data and associate metadata information with the stored data. The metadata storage system in SRB is modeled on the attribute-value pair representation. This data structure enables SRB to be used as a general purpose data management platform for a variety of application domains. However, the generic representation of metadata storage mechanism also proves to be a limitation for applications that depend on the extensive use of the associated metadata in order to provide customized search and query operations. The presented work addresses this limitation by providing a keyword based indexing system over the metadata stored in the SRB system. The system is tightly coupled with the SRB metadata catalog; thereby ensuring that the keyword indexes are always kept updated to reflect changes in the host SRB system.

Metadata

Metadata (or metainformation) is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of metadata, including: Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters.

Tag (metadata)

In information systems, a tag is a keyword or term assigned to a piece of information (such as an Internet bookmark, multimedia, database record, or ). This kind of metadata helps describe an item and allows it to be found again by browsing or searching. Tags are generally chosen informally and personally by the item's creator or by its viewer, depending on the system, although they may also be chosen from a controlled vocabulary. Tagging was popularized by websites associated with Web 2.

Metadata registry

A metadata registry is a central location in an organization where metadata definitions are stored and maintained in a controlled method. A metadata repository is the database where metadata is stored. The registry also adds relationships with related metadata types. A metadata engine collects, stores and analyzes information about data and metadata (data about data) in use within a domain. Metadata registries are used whenever data must be used consistently within an organization or group of organizations.
