aacr2

AACR2 stands for the Anglo-American Cataloguing Rules, Second Edition. It is published jointly by the American Library Association, the Canadian Library Association, and the Chartered Institute of Library and Information Professionals in the UK. The editor is Michael Gorman, a British-born librarian living in the Chicago area and honored by both the ALA and CILIP. AACR2 is designed for use in the construction of catalogues and other lists in general libraries of all sizes. The rules cover the description of, and the provision of access points for, all library materials commonly collected at the present time. Despite the claim to be 'Anglo-American', the first edition of AACR was published in 1967 in somewhat distinct North American and British texts. The second edition of 1978 unified the two sets of rules (adopting the British spelling 'cataloguing') and brought them in line with the International Standard Bibliographic Description. Libraries wishing to migrate from the previous North American text were obliged to implement 'desuperimposition', a substantial change in the form of headings for corporate bodies. As well as occasional minor amendments, a broader revision was completed in July 2010 in which the rules are more consistent and coherent, informed by the Functional Requirements for Bibliographic Records. This new cataloging code has been released as Resource Description and Access and is currently undergoing testing at a number of universities as well as the Library of Congress.

aiff

Audio Interchange File Format (AIFF) is an audio file format standard used for storing sound data for personal computers and other electronic audio devices.

amazon web services

Amazon Web Services (abbreviated AWS) is a collection of remote computing services (also called web services) that together make up a cloud computing platform, offered over the Internet by Amazon.com. The most central and well-known of these services are Amazon EC2 and Amazon S3. Launched in July 2002, Amazon Web Services provide online services for other web sites or client-side applications. Most of these services are not exposed directly to end users, but instead offer functionality that other developers can use in their applications. Amazon Web Services’ offerings are accessed over HTTP, using REST and SOAP protocols. All services are billed based on usage, but how usage is measured for billing varies from service to service.

application profile

In computer science, an application profile is a set of metadata elements, policies, and guidelines defined for a particular application. The elements may be from one or more element sets, thus allowing a given application to meet its functional requirements by using metadata from several element sets including locally defined sets. For example, a given application might choose a subset of the Dublin Core that meets its needs, or may include elements from the Dublin Core, another element set, and several locally defined elements, all combined in a single schema. An application profile is not complete without documentation that defines the policies and best practices appropriate to the application. (Excerpt from Wikipedia article: Application profile)

ark

Archival Resource Key (ARK) is a Uniform Resource Locator (URL) that provides a multi-purpose identifier given to information objects of any type. ARKs contain the label ark: in the URL, which sets the expectation that the URL terminated by '?' returns a brief metadata record, and the URL terminated by '??' returns metadata that includes a commitment statement from the current service provider. While ARKs have application in identifier persistence, the ARK scheme sees persistence as purely a matter of service and not a property of a naming syntax. The ARK inflections '?' and '??' are designed to permit service providers to convey to users some sense of their ability to provide persistence. (Excerpt from Wikipedia article: ARK)

ascii

The American Standard Code for Information Interchange is a character-encoding scheme based on the ordering of the English alphabet. ASCII codes represent text in computers, communications equipment, and other devices that use text. Most modern character-encoding schemes are based on ASCII, though they support many more characters than did ASCII. (Excerpt from Wikipedia article: ASCII)

asf

The Apache Software Foundation (ASF) is a non-profit corporation (classified as 501(c)(3) in the United States) to support Apache software projects, including the Apache HTTP Server. The ASF was formed from the Apache Group and incorporated in Delaware, U.S., in June 1999. The Apache Software Foundation is a decentralized community of developers. The software they produce is distributed under the terms of the Apache License and is therefore free and open source software (FOSS). The Apache projects are characterized by a collaborative, consensus-based development process and an open and pragmatic software license. Each project is managed by a self-selected team of technical experts who are active contributors to the project. The ASF is a meritocracy, implying that membership to the foundation is granted only to volunteers who have actively contributed to Apache projects. The ASF is considered a second generation open-source organization. Among the ASF's objectives are to provide legal protection to volunteers working on Apache projects, and to prevent the Apache brand name from being used by other organizations without permission. The ASF also holds several ApacheCon conferences each year, highlighting Apache projects, related technology, and encouraging Apache developers to gather together.

asx

The Advanced Stream Redirector (ASX) format is a type of XML metafile designed to store a list of Windows Media files to play during a multimedia presentation. It is used frequently on streaming video servers where multiple ASF files are to be played in succession. Both RTSP and MMS streaming protocols are supported, as well as HTTP. ASX files have MIME type video/x-ms-asf (as do ASF files). With the introduction of the WMA and WMV container formats, WAX and WVX extensions have also been introduced by Microsoft respectively.

atom

The name Atom applies to a pair of related standards. The Atom Syndication Format is an XML language used for web feeds, while the Atom Publishing Protocol (AtomPub or APP) is a simple HTTP-based protocol for creating and updating web resources. The Atom format was developed as an alternative to RSS. Ben Trott, an advocate of the new format that became Atom, believed that RSS had limitations and flaws - such as lack of on-going innovation and its necessity to remain backward compatible - and that there were advantages to a fresh design.Proponents of the new format formed the IETF Atom Publishing Format and Protocol Workgroup. The Atom syndication format was published as an IETF proposed standard in RFC 4287 (December 2005), and the Atom Publishing Protocol was published as RFC 5023 (October 2007).

audio codec

In software, an "audio codec" is a computer program that compresses/decompresses digital audio data according to a given audio file format or streaming audio format. The object of the algorithm is to represent the high-fidelity audio signal with minimum number of bits while retaining the quality. This can effectively reduce the storage space and the bandwidth required for transmission of the stored audio file. Most codecs are implemented as libraries which interface to one or more multimedia players, such as QuickTime Player, XMMS, Winamp, VLC media player, MPlayer or Windows Media Player. (Excerpt from Wikipedia article: Audio codec)

An authentication service is a structured network service that determines that the digital ID being presented to a network service is being used by the real-world individual who has the rights to use it. This is often achieved through the use of a username/password combination or a digital certificate, depending on the degree of assurance required.
