The Standard Generalized Markup Language (ISO 8879:1986 SGML) is an ISO-standard technology for defining generalized markup languages for documents. ISO 8879 Annex A.1 defines generalized markup: Generalized markup is based on two novel postulates: 1) Markup should describe a document's structure and other attributes, rather than specify the processing to be performed on it, as descriptive markup needs to be done only once, and will suffice for future processing. 2) Markup should be rigorous so that the techniques available for processing rigorously-defined objects like programs and databases can be used for processing documents as well.

further education

Further education (often abbreviated "FE", called continuing education in U.S. English) is a term mainly used in connection with education in the United Kingdom and the Republic of Ireland. It is post-compulsory education (in addition to that received at secondary school), that is distinct from the education offered in universities (higher education). It may be at any level above compulsory education, from basic training to Higher National Diploma or Foundation Degree. A distinction is usually made between FE and higher education ("HE") which is education at a higher level than secondary school, usually provided in distinct institutions such as universities. FE in the United Kingdom therefore includes education for people over 16, usually excluding universities. It is primarily taught in FE colleges (which are similar in concept to United States community colleges, and sometimes use "community college" in their title), work-based learning, and adult and community learning institutions.

A virtual learning environment (VLE) is a system designed to support teaching and learning in an educational setting, as distinct from a Managed Learning Environment (MLE), where the focus is on management.A VLE will normally work over the Internet and provide a collection of tools such as those for assessment (particularly of types that can be marked automatically, such as multiple choice), communication, uploading of content, return of students' work, peer assessment, administration of student groups, collecting and organizing student grades, questionnaires, tracking tools, etc. New features in these systems include wikis, blogs, RSS and 3D virtual learning spaces. VLEs are often used in schools and other educational establishments in order to make the learning experience more interactive. While originally created for distance education, VLEs are now most often used to supplement traditional face to face classroom activities, commonly known as Blended Learning. These systems usually run on servers, to serve the course to students Multimedia and/or web pages. (Excerpt from Wikipedia article: Virtual learning environment)

resource description and access

Resource Description and Access or RDA is a set of instructions for the cataloguing of books and other materials held in libraries and other cultural organizations such as museums and galleries. RDA is the successor to the second edition of the Anglo-American Cataloguing Rules (AACR2), the current standard set of cataloguing guidelines for English language libraries. It was initially released in summer 2010, and in the United States, following widespread controversy amongst cataloguers, the three national libraries (Library of Congress, National Library of Medicine, and the National Agricultural Library) organized a nation-wide test of the new standards.

library management systems

An integrated library system (ILS), also known as a library management system (LMS), is an enterprise resource planning system for a library, used to track items owned, orders made, bills paid, and patrons who have borrowed. An ILS usually comprises a relational database, software to interact with that database, and two graphical user interfaces (one for patrons, one for staff). Most ILSes separate software functions into discrete programs called modules, each of them integrated with a unified interface. Examples of modules might include: acquisitions (ordering, receiving, and invoicing materials); cataloging (classifying and indexing materials); circulation (lending materials to patrons and receiving them back); serials (tracking magazine and newspaper holdings); the OPAC (public interface for users). Each patron and item has a unique ID in the database that allows the ILS to track its activity. Larger libraries use an ILS to order and acquire, receive and invoice, catalog, circulate, track and shelve materials. (Excerpt from Wikipedia article: Library management system)

Shibboleth is an Internet2 Middleware Initiative project that has created an architecture and open-source implementation for federated identity-based authentication and authorization infrastructure based on Security Assertion Markup Language (SAML). Federated identity allows for information about users in one security domain to be provided to other organizations in a federation. This allows for cross-domain single sign-on and removes the need for content providers to maintain user names and passwords. Identity providers (IdPs) supply user information, while service providers (SPs) consume this information and get access to secure content. (Excerpt from Wikipedia article: Shibboleth)

web development

Web development (or web management) is a broad term for the work involved in developing a web site for the Internet (World Wide Web) or an intranet (a private network). This can include web design, web content development, client liaison, client-side / server-side scripting, web server and network security configuration, and e-commerce development. However, among web professionals, "web development" usually refers to the main non-design aspects of building web sites: writing markup and coding. Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, or social network services. For larger organizations and businesses, web development teams can consist of hundreds of people (web developers). Smaller organizations may only require a single permanent or contracting webmaster, or secondary assignment to related job positions such as a graphic designer and/or information systems technician. Web development may be a collaborative effort between departments rather than the domain of a designated department. (Excerpt from Wikipedia article: Web development)

virtual research environment

A virtual research environment (VREs) or virtual laboratory is an online system helping researchers collaborate. Features usually include collaboration support (forums and wikis), document hosting, and some discipline-specific tools, such as data analysis, visualisation, or simulation management. In some instances, publication management, and teaching tools such as presentations and slides may be included. VREs have become important in fields where research is primarily carried out in teams which span institutions and even countries: the ability to easily share information and research results is valuable. The concept of the VRE was studied by UK funding agency JISC in 2010 which highlighted issues such as researcher involvement in VRE design, sustainability, and consideration of the project as primarily one of community building rather than technology. The report also noted synonyms such as "collaborative e-research community", "collaboratory" and "virtual research community". JISC funded development of a number of VREs under its "Virtual research environment programme" from 2004 to 2011. In Australia, e-Research body NeCTAR has funding for a "virtual laboratory" program to be allocated in 2011. (Excerpt from Wikipedia article: Virtual research environment)

web resources

The concept of resource is primitive in the Web architecture, and is used in the definition of its fundamental elements. The term was first introduced to refer to targets of Uniform Resource Locators (URLs), but its definition has been further extended to include the referent of any Uniform Resource Identifier (RFC 3986), or Internationalized Resource Identifier (RFC 3987). In the Semantic Web, abstract resources and their semantic properties are described using the family of languages based on Resource Description Framework (RDF).

In computer science and information science, an ontology is a formal representation of knowledge as a set of concepts within a domain, and the relationships between those concepts. It is used to reason about the entities within that domain, and may be used to describe the domain. Its meaning is vastly different from the word Ontology in philosophy. In theory, an ontology is a "formal, explicit specification of a shared conceptualisation". An ontology provides a shared vocabulary, which can be used to model a domain - that is, the type of objects and/or concepts that exist, and their properties and relations. Ontologies are the structural frameworks for organizing information and are used in artificial intelligence, the Semantic Web, systems engineering, software engineering, biomedical informatics, library science, enterprise bookmarking, and information architecture as a form of knowledge representation about the world or some part of it. The creation of domain ontologies is also fundamental to the definition and use of an enterprise architecture framework. (Excerpt from Wikipedia article: Ontology)

Perl is a high-level, general-purpose, interpreted, dynamic programming language. Perl was originally developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions and become widely popular amongst programmers. Larry Wall continues to oversee development of the core language, and its upcoming version, Perl 6. Perl borrows features from other programming languages including C, shell scripting (sh), AWK, and sed. The language provides powerful text processing facilities without the arbitrary data length limits of many contemporary Unix tools, facilitating easy manipulation of text files. Perl gained widespread popularity in the late 1990s as a CGI scripting language, in part due to its parsing abilities. (Excerpt from Wikipedia article: Perl)

A thesaurus is a reference work that lists words grouped together according to similarity of meaning (containing synonyms and sometimes antonyms), in contrast to a dictionary, which contains definitions and pronunciations. In Information Science, Library Science, and Information Technology, specialized thesauri are designed for information retrieval. They are a type of controlled vocabulary, for indexing or tagging purposes. Such a thesaurus can be used as the basis of an index for online material. The Art and Architecture Thesaurus, for example, is used to index the Canadian Information retrieval thesauri are formally organized so that existing relationships between concepts are made explicit. As a result, they are more complex than simpler controlled vocabularies such as authority lists and synonym rings. Each term is placed in context, allowing a user to distinguish between "bureau" the office and "bureau" the furniture. Following international standards, they are generally arranged hierarchically by themes, topics or facets. Unlike a literary thesaurus, these specialized thesauri typically focus on one discipline, subject or field of study. In information technology, a thesaurus represents a database or list of semantically orthogonal topical search keys. In the field of Artificial Intelligence, a thesaurus may sometimes be referred to as an ontology. (Excerpt from Wikipedia article: Thesaurus)

information retrieval

Information retrieval (IR) is the area of study concerned with searching for documents, for information within documents, and for metadata about documents, as well as that of searching structured storage, relational databases, and the World Wide Web. There is overlap in the usage of the terms data retrieval, document retrieval, information retrieval, and text retrieval, but each also has its own body of literature, theory, praxis, and technologies. IR is interdisciplinary, based on computer science, mathematics, library science, information science, information architecture, cognitive psychology, linguistics, and statistics. Automated information retrieval systems are used to reduce what has been called "information overload". Many universities and public libraries use IR systems to provide access to books, journals and other documents. Web search engines are the most visible IR applications.

A CD-ROM (acronym of "Compact Disc Read-only memory") is a pre-pressed compact disc that contains data accessible to, but not writable by, a computer for data storage and music playback. The 1985 'Yellow Book' standard developed by Sony and Philips adapted the format to hold any form of binary data. CD-ROMs are popularly used to distribute computer software, including video games and multimedia applications, though any data can be stored (up to the capacity limit of a disc). Some CDs hold both computer data and audio with the latter capable of being played on a CD player, while data (such as software or digital video) is only usable on a computer (such as ISO 9660 format PC CD-ROMs). These are called enhanced CDs. (Excerpt from Wikipedia article: CD-ROM)

intellectual property

Intellectual property (IP) is a term referring to a number of distinct types of creations of the mind for which a set of exclusive rights are recognized - and the corresponding fields of law. Under intellectual property law, owners are granted certain exclusive rights to a variety of intangible assets, such as musical, literary, and artistic works; discoveries and inventions; and words, phrases, symbols, and designs. Common types of intellectual property include copyrights, trademarks, patents, industrial design rights and trade secrets in some jurisdictions.

E-Science (or eScience) is computationally intensive science that is carried out in highly distributed network environments, or science that uses immense data sets that require grid computing; the term sometimes includes technologies that enable distributed collaboration, such as the Access Grid. The term was created by John Taylor, the Director General of the United Kingdom's Office of Science and Technology in 1999 and was used to describe a large funding initiative starting in November 2000. Examples of the kind of science include social simulations, particle physics, earth sciences and bio-informatics. Particle physics has a well developed e-Science infrastructure in particular because of its need for adequate computing facilities for the analysis of results and storage of data originating from the CERN Large Hadron Collider, which started taking data in 2009.

collection description

The description of collections is important in the context of network library services and an important underpinning for developing a collective resource. The creation of collection descriptions allows the owners or curators of collections to disclose information about their existence and availability to interested parties. Although collection descriptions may take the form of unstructured textual documents (for example a set of Web pages describing a collection), there are significant advantages in describing collections using structured, open and standardised formats. Such descriptions would enable: users to discover and locate collections of interest; users to perform searches across multiple collections in a controlled way; software to perform such tasks on behalf of users, based on known user preferences.
