open education

Open education is a collective term to describe institutional practices and programmatic initiatives that broaden access to the learning and training traditionally offered through formal education systems. The qualifier 'open' of open education refers to the elimination of barriers that can preclude both opportunities and recognition for participation in institution-based learning. One aspect of openness in or 'opening up' education is the development and adoption of open educational resources. (Excerpt from Wikipedia article: Open Education)

A mobile device (also known as a handheld device, handheld computer or simply handheld) is a pocket-sized computing device, typically having a display screen with touch input and/or a miniature keyboard. In the case of the personal digital assistant (PDA) the input and output are often combined into a touch-screen interface. Smartphones and PDAs are popular amongst those who require the assistance and convenience of certain aspects of a conventional computer, in environments where carrying one would not be practical. Enterprise digital assistants can further extend the available functionality for the business user by offering integrated data capture devices like barcode, RFID and smart card readers.

open data

Open data is a philosophy and practice requiring that certain data be freely available to everyone, without restrictions from copyright, patents or other mechanisms of control. It has a similar ethos to a number of other "Open" movements and communities such as open source and open access. However these are not logically linked and many combinations of practice are found. The practice and ideology itself is well established (for example in the Mertonian tradition of science) but the term "open data" itself is recent. Much of the emphasis in this entry is on data from scientific research and from the data-driven web. In some cases open data may be considered as more properly Open Metadata and there is not yet a consistent formalisation. (Excerpt from Wikipedia article: Open data)

collection development

Library collection development is the process of meeting the information needs of the people (a service population) in a timely and economical manner using information resources locally held, as well as from other organizations. According to the The International Federation of Library Associations and Institutions (IFLA), acquisition and collection development focuses on methodological and topical themes pertaining to acquisition of print and other analogue library materials (by purchase, exchange, gift, legal deposit), and the licensing and purchase of electronic information resources. Collections are developed by librarians and library staff by buying or otherwise acquiring materials over a period, based on assessment of the information needs of the library's users.

linked data

Linked Data describes a method of publishing structured data, so that it can be interlinked and become more useful. It builds upon standard Web technologies, such as HTTP and URIs - but rather than using them to serve web pages for human readers, it extends them to share information in a way that can be read automatically by computers. This enables data from different sources to be connected and queried. Tim Berners-Lee, director of the World Wide Web Consortium, coined the term in a design note discussing issues around the Semantic Web project. (Excerpt from Wikipedia article: Linked Data)

open access

Open access (OA) refers to unrestricted online access to articles published in scholarly journals, and increasingly also book chapters or monographs. Open Access comes in two forms, Gratis versus Libre: Gratis OA is no-cost online access, while Libre OA offers some additional usage rights. Open content is similar to OA, but usually includes the right to modify the work, whereas in scholarly publishing it is usual to keep an article's content intact and to associate it with a fixed author. Creative Commons licenses can be used to specify usage rights. The Open Access idea can be extended to the learning objects and resources provided in e-learning. OA can be provided in two ways: 1) "Green OA" is provided by authors publishing in any journal and then self-archiving their postprints in their institutional repository or on some other OA website. Green OA journal publishers endorse immediate OA self-archiving by their authors. 2) "Gold OA" is provided by authors publishing in an open access journal that provides immediate OA to all of its articles on the publisher's website. (Hybrid open access journals provide Gold OA only for those individual articles for which their authors (or their author's institution or funder) pay an OA publishing fee.)

A repository in publishing, and especially in academic publishing, is a real or virtual facility for the deposit of academic publications, such as academic journal articles. Deposit of material in such a site may be mandatory for a certain group, such as a particular university's doctoral graduates in a thesis repository, or published papers from those holding grants from a particular government agency in a subject repository, or, sometimes, in their own institutional repository. Or it may be voluntary, as usually the case for technical reports at a university. (Excerpt from Wikipedia article: Repository)

cloud computing

Cloud computing refers to the provision of computational resources on demand via a computer network. In the traditional model of computing, both data and software are fully contained on the user's computer; in cloud computing, the user's computer may contain almost no software or data (perhaps a minimal operating system and web browser only), serving as little more than a display terminal for processes occurring on a network of computers far away. A common shorthand for a provider's cloud computing service (or even an aggregation of all existing cloud services) is "The Cloud". (Excerpt from Wikipedia article: Cloud computing)

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. (Excerpt from Wikipedia article: QR code)

Research can be defined as the search for knowledge, or as any systematic investigation, with an open mind, to establish novel facts, usually using a scientific method. The primary purpose for basic research (as opposed to applied research) is discovering, interpreting, and the development of methods and systems for the advancement of human knowledge on a wide variety of scientific matters of our world and the universe.

The term data refers to qualitative or quantitative attributes of a variable or set of variables. Data (plural of "datum") are typically the results of measurements and can be the basis of graphs, images, or observations of a set of variables. Data are often viewed as the lowest level of abstraction from which information and then knowledge are derived. Raw data, i.e. unprocessed data, refers to a collection of numbers, characters, images or other outputs from devices that collect information to convert physical quantities into symbols.

A smartphone is a mobile phone that offers more advanced computing ability and connectivity than a contemporary feature phone. Smartphones and feature phones may be thought of as handheld computers integrated with a mobile telephone, but while most feature phones are able to run applications based on platforms such as Java ME, a smartphone allows the user to run and preemptively multitask applications that are native to the underlying hardware. Smartphones run complete operating system software providing a platform for application developers. Thus, they combine the functions of a camera phone and a personal digital assistant (PDA).

Digitising or digitisation is the representation of an object, image, sound, document or a signal (usually an analog signal) by a discrete set of its points or samples. The result is called digital representation or, more specifically, a digital image, for the object, and digital form, for the signal. Strictly speaking, digitizing means simply capturing an analog signal in digital form. For a document the term means to trace the document image or capture the "corners" where the lines end or change direction. (Excerpt from Wikipedia article: Digitisation)

A massive open online course (MOOC) is an online course aimed at large-scale interactive participation and open access via the web. In addition to traditional course materials such as videos, readings, and problem sets, MOOCs provide interactive user forums that help build a community for the students, professors, and teaching assistants (TAs). MOOCs are a recent development in distance education. Features associated with early MOOCs, such as open licensing of content, open structure and learning goals, and connectivism may not be present in all MOOC projects, in particular with the 'openness' of many MOOCs being called into question.
