Group Definitions


Access: Permission and ability to find, examine, and use information freely (Society of American Archivists, 2005).

Computer-output microfilm: Copying electronic data from a computer onto microfilm or microfiche using laser technology and a film processor (Gavitt, 2000).

Obsolescence: A state that occurs when software, hardware, or other media platform becomes outdated and is superseded by a new and superior object, service, practice, etc., which renders it difficult to use or completely unusable.

PREMIS: PREservation Metadata: Implementation Strategies. A preservation metadata standard that includes a data dictionary that defines a set of semantic units (pieces of information) institutions can use for digital preservation (Caplan, 2009).

PURL: Persistent Uniform Resource Locator. A permanent identifier URL that redirects the user to an active page containing the resource the user is looking for (e.g., if a user types in a URL that has changed, the PURL will redirect to the current URL) (OCLC Bibliographic PURL Service). This allows the underlying web addresses of resources to change over time without negatively affecting systems that depend on them (OCLC PURL).

Refresh: A preservation method that entails copying data from an older media type onto a newer version of the same media type to avoid data loss due to media deterioration or replacement.

ERM: Electronic Resource Management. Systems used to manage and provide access to electronic resources, especially internet-based resources such as electronic journals, databases, and electronic books (Beals, 2008). The development of ERM became necessary in the early 2000s as it became clear that traditional library catalogs and integrated library systems were not designed to handle metadata for resources as mutable as many online products are (Electronic Resource Management, 2010).

Binary: Computer language based on “0s” and “1s” used to encode data in computer systems.

Legacy system: Outdated or obsolete technology and equipment that is still being used by an individual or organization, typically because it still functions for the users’ needs, even though newer technology or more efficient methods of performing a task are now available (Legacy Systems, 2010).

Legacy Systems. (2010). Retrieved February 22, 2010, from http://en.wikipedia.org/wiki/Legacy_system.

Dark archive: A collection that is preserved for future use but is not currently accessible to users (Society of American Archivists, 2005).

iRODS: i Rule Oriented Data Systems. A software system used for encoding customization of data management functions (IRODS, 2010) and organizing sharable data (Moore, 2009).

IRODS: Data Grids, Digital Libraries, Persistent Archives, and Real-time Data Systems website. (2010). Retrieved February 21, 2010, from https://www.irods.org.

Generation: The reproduction cycles between a copy and its original material. The Society of American Archivists (2005) gives the example that a print made from a negative would be a first-generation copy, while a reproduction made from that print would be a second-generation copy.

Society of American Archivists. (2005).A Glossary of Archival and Records Terminology. Retrieved February 21, 2010, from http://www.archivists.org/glossary/term_details.asp?DefinitionKey=779.

Open access: When copyright owners relinquish some of their copyright rights to allow unrestricted internet access to their materials (Anderson, 2006).

Anderson, B. (2006). A primer on copyright law and the DMCA. Reference Librarian, 45(93), 59-71.

Web crawler: An automated program that methodically scans the internet to create an index of information sources (Web Crawler, 2010).
