Avatar

An avatar is a 'virtual' being, a graphical representation of the user. In a multiuser world there may be many avatars. Although avatars often have human characteristics, this is not an essential feature and other forms of graphical representation can be used. An avatar is not limited to 3D virtual environments but can be present in 2D graphic environments.

CSV

In computing, a CSV file contains the values from a data table as a series of ASCII text lines organized so that each column value is separated by a comma and each row starts a new line. This special format of text file is often used when transferring data from one spreadsheet (or database) to another.

ERP

ERP (Enterprise Resource Planning)
ERP is an industry term for the broad set of activities supported by multi-module application software that help a manufacturer or other types of business manage important parts of their activities, including product planning, parts purchasing, maintaining inventories, interacting with suppliers, providing customer service, and tracking orders. ERP can also include application modules for the finance and human resources aspects of a business. Typically, an ERP system uses or is integrated with a relational database system. The deployment of an ERP system can involve considerable business process analysis, employee retraining, and new work procedures.

H. 323

H.323 is an ITU (International Telecommunications Union) standard for videoconferencing over local area networks and packet-switched networks generally. It is based on a recognised real-time standard and is commonly used when video is transmitted via the Internet to ensure that users can communicate with each other, as long as they are using videoconferencing software which complies with the standard, e.g. Microsoft NetMeeting, Netscape Conference. The standard applies both to one-to-one and multi-party videoconferences.

HTML (Hypertext Markup Language)

HTML is a markup language used to create hypertext documents that are platform independent. HTML documents are SGML documents with generic semantics that are appropriate for representing information from a wide range of domains. HTML markup can represent hypertext news, mail, documentation, and hypermedia; menus of options; database query results; simple structured documents with in-lined graphic; and hypertext views of existing bodies of information.

ISDN (Integrated Services Digital Network)

ISDN is a system of digital telephone connections. It allows multiple digital channels to be operated simultaneously through a single, standard interface. The Basic Rate Interface (BRI) consists of two 64 kbps plus another lower rate channel to handle signalling. Primary Rate Interface (PRI) consists of 23 channels plus a signalling channel. ISDN is adequate for videoconferencing and other high bandwidth applications. The cost of an ISDN line is normally higher than a normal phone line, and special equipment is required

IST

Information Society Technologies Programme (IST)
IST is a single, integrated research programme that builds on the convergence of information processing, communications and media technologies. IST has an indicative budget of 3.600 Million Euro, and is managed by the Information Society DG of the European Commission.

MPEG4 (Moving Picture Experts Group)

MPEG4 is the most recent version of a standard for the digital representation of video, audio and certain types of 3D information. It processes detailed 3D representation for faces, human bodies and general 3D scenes. The 3D scene representation points to the VRML standard as it's representation.

PCC

Project Coordination Committee (PCC)
The overall management will be the responsibility of a Project Coordination Committee (PCC), that will consist of representatives of the principal contractors. The chair of the PCC will be the project co-ordinator of the SHOP-LAB project. The major tasks of the PCC will be the control of project progress, resource spend, quality assurance, and, in case of problems,
the definition of solutions, corrections, resource reallocation etc..

All basic project decisions will be taken by the PCC. The PCC shall meet at least quarterly

SGML (Standard Generalised Mark-up Language)

SGML is a widely used document format. SGML uses tags as part of a general framework for describing a document structure.

SQL (Structured Query Language)

SQL is a computer language developed for use with relational database systems. Has an extensive set of commands that allow the user to define, manage and analyse/query the database.

SSL (Secure Socket Layer)

SSL is a protocol developed by Netscape Communications Corporation for securing data transmission in commercial transactions on the Internet. Using public-key cryptography, SSL provides server authentication, data encryption, and data integrity for client/server communications.

TFT (Thin Film Transistor)

TFT is a type of Liquid Crystal Display (LCD) flat panel display screen, in which each pixel is controlled by anything from one to four transistors. The TFT technology provides the best resolution of all the flat panel techniques, but it is also the most expensive. TFT screens are sometimes called active matrix LCDs.

VRML (Virtual Reality Modeling Language)

VRML is an acronym for an ISO standard (ISO 14772). Its official name is VRML97. It is a standard for the description of 3D graphics for the Web. The 3D graphics are displayed using a VRML browser
