Term Brief description Charts

portal

A web portal or links page is a web site that functions as a point of access to information on the World Wide Web. A portal presents information from diverse sources in a unified way. Apart from the standard search engine feature, web portals offer other services such as e-mail, news, stock prices, information, databases and entertainment. Portals provide a way for enterprises to provide a consistent look and feel with access control and procedures for multiple applications and databases, which otherwise would have been different entities altogether. Examples of public web portals are AOL, Excite, iGoogle, MSN, Netvibes, and Yahoo! (Excerpt from <a href="http://en.wikipedia.org/wiki/Web_portal">Wikipedia article: Portal</a>)

portfolio

An electronic portfolio, also known as an e-portfolio or digital portfolio, is a collection of electronic evidence assembled and managed by a user, usually on the Web. Such electronic evidence may include inputted text, electronic files, images, multimedia, blog entries, and hyperlinks. E-portfolios are both demonstrations of the user's abilities and platforms for self-expression, and, if they are online, they can be maintained dynamically over time. Some e-portfolio applications permit varying degrees of audience access, so the same portfolio might be used for multiple purposes. An e-portfolio can be seen as a type of learning record that provides actual evidence of achievement. Learning records are closely related to the Learning Plan, an emerging tool that is being used to manage learning by individuals, teams, communities of interest, and organizations. To the extent that a Personal Learning Environment captures and displays a learning record, it also might be understood to be an electronic portfolio.

preservation

Digital preservation is the active management of digital information over time to ensure its accessibility. Preservation of digital information is widely considered to require more constant and ongoing attention than preservation of other media. This constant input of effort, time, and money to handle rapid technological and organizational advance is considered a major stumbling block for preserving digital information. Indeed, while we are still able to read our written heritage from several thousand years ago, the digital information created merely a decade ago is in serious danger of being lost, creating a digital Dark Age.

preservation metadata

Preservation metadata is an essential component of most digital preservation strategies. As an increasing proportion of the world's information output shifts from analog to digital form, it is necessary to develop new strategies to preserve this information for the long-term. Preservation metadata is information that supports and documents the digital preservation process. Preservation metadata is sometimes considered a subset of technical or administrative metadata. Preservation metadata stores technical details on the format, structure and use of the digital content, the history of all actions performed on the resource including changes and decisions, the authenticity information such as technical features or custody history, and the responsibilities and rights information applicable to preservation actions. Preservation metadata is access-centered and should accomplish four themes: include details about files and instructions for use; document all updates or actions that have occurred to an object; show provenance and demonstrate current and future custody; list details on the individual(s) who are responsible for the preservation of the object.

privacy

Privacy is the ability of an individual or group to seclude themselves or information about themselves and thereby reveal themselves selectively. The boundaries and content of what is considered private differ among cultures and individuals, but share basic common themes. Privacy is sometimes related to anonymity, the wish to remain unnoticed or unidentified in the public realm. When something is private to a person, it usually means there is something within them that is considered inherently special or personally sensitive. The degree to which private information is exposed therefore depends on how the public will receive this information, which differs between places and over time. Privacy partially intersects security, including for instance the concepts of appropriate use, as well as protection, of information.

purl

A persistent uniform resource locator (PURL) is a Uniform Resource Locator (URL) (i.e. location-based Uniform Resource Identifier or URI) that is used to redirect to the location of the requested Web resource. PURLs redirect HTTP clients using HTTP status codes. PURLs are used to curate the URL resolution process, thus solving the problem of transitory URIs in location-based URI schemes like HTTP. Technically the string resolution on PURL is like SEF URL resolution. (Excerpt from <a href="http://en.wikipedia.org/wiki/Persistent_Uniform_Resource_Locator">Wikipedia article: PURL</a>)

python

Python is an interpreted, general-purpose high-level programming language whose design philosophy emphasizes code readability. Python aims to combine "remarkable power with very clear syntax", and its standard library is large and comprehensive. Its use of indentation for block delimiters is unique among popular programming languages. Python supports multiple programming paradigms, primarily but not limited to object-oriented, imperative and, to a lesser extent, functional programming styles. It features a fully dynamic type system and automatic memory management, similar to that of Scheme, Ruby, Perl, and Tcl. Like other dynamic languages, Python is often used as a scripting language, but is also used in a wide range of non-scripting contexts.

qr code

A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two-dimensional code) designed to be read by smartphones. The code consists of black modules arranged in a square pattern on a white background. The information encoded may be text, a URL, or other data. Created by Toyota subsidiary Denso Wave in 1994, the QR code is one of the most popular types of two-dimensional barcodes. The QR code was designed to allow its contents to be decoded at high speed. The technology has seen frequent use in Japan and South Korea; the United Kingdom is the seventh-largest national consumer of QR codes.

rae

The Research Assessment Exercise (RAE) is an exercise undertaken approximately every 5 years on behalf of the four UK higher education funding councils (HEFCE, SHEFC, HEFCW, DELNI) to evaluate the quality of research undertaken by British higher education institutions. RAE submissions from each subject area (or unit of assessment) are given a rank by a subject specialist peer review panel. The rankings are used to inform the allocation of quality weighted research funding (QR) each higher education institution receives from their national funding council. Previous RAEs took place in 1986, 1989, 1992, 1996 and 2001. The most recent results were published in December 2008. Various media have produced league tables of institutions and disciplines based on the 2008 RAE results. Different methodologies lead to similar but non-identical rankings.

raptor

The Retrieval, Analysis, and Presentation Toolkit for usage of Online Resources (RAPTOR) project was designed to build a free-to-use, open source software toolkit for reporting e-resource usage statistics (from Shibboleth IdPs and EZProxy) in a user-friendly manner suitable for non-technical staff. Given the current economic climate and likelihood of tightening funding, understanding the usage of e-resources is becoming increasingly important as it allows an institution to understand which resources they need to keep subscribing to, and those which they may wish to unsubscribe from (potentially resulting in cost savings).

rdbms

A relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model as introduced by E. F. Codd. Most popular databases currently in use are based on the relational database model. A short definition of an RDBMS is: a DBMS in which data is stored in tables and the relationships among the data are also stored in tables. The data can be accessed or reassembled in many different ways without having to change the table forms.
