From other proposal work:

API

Application Programming Interface, a defined technical interface that allows one software component to utilize functions provided by another.

ATOM

a development of RSS that is being standardized by the IETF.

CIDOC

CIDOC is the international focus for the documentation interests of museums and similar organisations. It is a constituent committee of the International Council of Museums (ICOM). See http://www.willpowerinfo.myby.co.uk/cidoc/cidoc0.htm.

CIDOC CRM

CIDOC Conceptual Reference Model

CIDOC CRM Core

a distillation of the essential concepts from CIDOC CRM that are applicable to activities that range beyond CIDOC's original domain of cultural heritage (e.g. scientific experimental procedures).

CPU

Central Processing Unit, the main "programmable calculator" that executes programs on a computer

DOI

Digital Object Identifier, a form of identifiers, and a framework for their allocation, used by publishing, digital library and other communities. See http://www.doi.org/.

GPU

Graphics Processing Unit, the main processor (CPU) on a graphics card. During the last 10 years, graphics processing has been increasingly offloaded from the main CPU to a separate processor (the GPU) on a separate circuit board (the graphics card). The performance of these cards has improved dramatically, enabling high quality 3D graphics at interactive rates on a common PC

IETF

Internet Engineering Task Force, the standards body reposible for defining and documenting technical interoperation specifications for the Internet, and some Internet applications.

LSID

Life Science Identifier, a form of identifier used by the life science research community. An LSID is a URN, which itself is a form of URI. See http://lsid.sourceforge.net/.

NFC

Near Field Communication

OWL

Web Ontology Language, a web language for describing classes of resources and how they relate to one another. See http://www.w3.org/2001/sw/ and http://www.w3.org/2004/OWL/.

PDA

Personal Digital Assistant, a handheld computer usually used as a personal organizer (e.g. as a calendar, notebook, etc.)

POI

Point of interest

RDF

Resource Description Framework, a data model and format for describing resources on the World Wide Web. See http://www.w3.org/2001/sw/ and http://www.w3.org/RDF/.

REST

REpresentational State Transfer, a software architectural style for distributed web applications that employs a small set of common interface functions and flexible data formats to convey the complexities of application interactions. This approach allows distributed components to evolve more freely than RPC approaches for distributed applications.

RGB

Red Green Blue, the most common model to specify a colour. The amount of red, green, and blue light is specified on a range from 0 to 100%, which are then mixed to produce a single colour (for example, on a typical computer flatscreen a single pixel is made up of tiny red, green, and blue lights).

RPC

Remote Procedure Call, a software technique for creating networked applications, in which a function invoked on one computer is executed on another network-connected computer.

RSS

This acronym has various interpretations (originally: Rich Site Summary), and is used to describe a family of data syndication formats. An RSS¬data feed is essentially a collection of "article" descriptions, each of which contains metadata about some web information resource. RSS is commonly used to transmit summary information about the content of dynamic web sites and services. See also ATOM.

SKOS

Simple Knowledge Organisation Systems. See http://www.w3.org/2004/02/skos/ and http://en.wikipedia.org/wiki/SKOS.

SPARQL

Query language and protocol for the semantic web. See http://en.wikipedia.org/wiki/SPARQL, http://www.w3.org/TR/rdf-sparql-query/ and http://www.w3.org/TR/rdf-sparql-protocol/.

URI

Uniform Resource Identifier, a form of identifier used on the web, defined in http://www.ietf.org/rfc/rfc3986.txt. Other identifier forms such as DOIs and LSIDs can be rendered as URIs.

URN

Uniform Resource Name, a Uniform Resource Identifier (URI) that uses the 'urn' scheme. See http://www.ietf.org/rfc/rfc2141.txt and http://www.w3.org/TR/uri-clarification/.

VSC

Virtual Service Compositor

W3C

World Wide Web Consortium, a body that defines technical specifications for the World Wide Web. These build upon specifications of the IETF.

WWW

World Wide Web. Sometimes written 'W3'.
