Streaming media is multimedia that is constantly received by and presented to an end-user while being delivered by a streaming provider.[note 1] The name refers to the delivery method of the medium rather than to the medium itself. The distinction is usually applied to media that are distributed over telecommunications networks, as most other delivery systems are either inherently streaming (e.g., radio, television) or inherently non-streaming (e.g., books, video cassettes, audio CDs). The verb 'to stream' is also derived from this term, meaning to deliver media in this manner. Internet television is a commonly streamed medium. (Excerpt from Wikipedia article: Streaming)

The Gopher protocol is a TCP/IP application layer protocol designed for distributing, searching, and retrieving documents over the Internet. Strongly oriented towards a menu-document design, the Gopher protocol was a predecessor of (and later, an alternative to) the World Wide Web. The protocol offers some features not natively supported by the Web and imposes a much stronger hierarchy on information stored on it. Its text menu interface is well-suited to computing environments that rely heavily on remote text-oriented computer terminals, which were still common at the time of its creation in 1991, and the simplicity of its protocol facilitated a wide variety of client implementations. Although largely supplanted by the Web in the years following, the Gopher protocol is still in use by enthusiasts, and a small population of actively-maintained servers remains.

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)

controlled vocabularies

Controlled vocabularies provide a way to organize knowledge for subsequent retrieval. They are used in subject indexing schemes, subject headings, thesauri and taxonomies. Controlled vocabulary schemes mandate the use of predefined, authorised terms that have been preselected by the designer of the vocabulary, in contrast to natural language vocabularies, where there is no restriction on the vocabulary.

FOAF (an acronym of Friend of a friend) is a machine-readable ontology describing persons, their activities and their relations to other people and objects. Anyone can use FOAF to describe him or herself. FOAF allows groups of people to describe social networks without the need for a centralised database. FOAF is a descriptive vocabulary expressed using the Resource Description Framework (RDF) and the Web Ontology Language (OWL). Computers may use these FOAF profiles to find, for example, all people living in Europe, or to list all people both you and a friend of yours know. This is accomplished by defining relationships between people. Each profile has a unique identifier (such as the person's e-mail addresses, a Jabber ID, or a URI of the homepage or weblog of the person), which is used when defining these relationships.

information architecture

Information architecture (IA) is the art of expressing a model or concept of information used in activities that require explicit details of complex systems. Among these activities are library systems, Content Management Systems, web development, user interactions, database development, programming, technical writing, enterprise architecture, and critical system software design. Information architecture has somewhat different meanings in these different branches of IS or IT architecture. Most definitions have common qualities: a structural design of shared environments, methods of organizing and labeling websites, intranets, and online communities, and ways of bringing the principles of design and architecture to the digital landscape.

The iPad is a line of tablet computers designed, developed and marketed by Apple Inc. primarily as a platform for audio-visual media including books, periodicals, movies, music, games, and web content. Its size and weight falls between those of contemporary smartphones and laptop computers. The iPad runs the same operating system as the iPod Touch and iPhone - and can run its own applications as well as iPhone applications. Without modification, and with the exception of websites, it will only run programs approved by Apple and distributed via its online store. (Excerpt from Wikipedia article: IPad)

In general, a namespace is a container that provides context for the identifiers (names, or technical terms, or words) it holds, what allows the disambiguation of homonym identifiers residing in different namespaces. For many programming languages, a namespace is a context for their identifiers. In an operating system, an example of namespace is a directory. Each name in a directory uniquely identifies one file or subdirectory, but one file may have the same name multiple times. (Excerpt from Wikipedia article: Namespace)

JSTOR (pronounced jay-stor; short for Journal Storage) is a digital library founded in 1995. Originally containing digitized back issues of academic journals, it now also includes books and primary sources, and current issues of journals. It provides full-text searches of more than a thousand journals, dating back to 1665 in the case of the Philosophical Transactions of the Royal Society. More than 7,000 institutions in more than 150 countries have access to JSTOR. Most access is by subscription, but some old public domain content is freely available to anyone, and in 2012 JSTOR launched a program of free access to some further articles for individual scholars and researchers who register. JSTOR was originally funded by the Andrew W. Mellon Foundation, but is now an independent, self-sustaining not-for-profit organization with offices in New York City and Ann Arbor, Michigan. In January 2009, JSTOR merged with ITHAKA, becoming part of that organization. ITHAKA is a non-profit organization founded in 2003 "dedicated to helping the academic community take full advantage of rapidly advancing information and networking technologies".

E-Government (short for electronic government, also known as e-gov, digital government, online government, or connected government) is digital interactions between a government and citizens (G2C), government and businesses/Commerce (G2B), government and employees, and also between government and governments /agencies (G2G). Essentially, the e-Government delivery models can be briefly summed up as (Jeong, 2007): G2C (Government to Citizens); G2B (Government to Businesses); G2E (Government to Employees); G2G (Government to Governments). This digital interaction consists of governance, information and communication technology (ICT), business process re-engineering (BPR), and e-citizen at all levels of government (city, state/provence, national, and international).

CERIF (Common European Research Information Format) emerged first as a simple standard not unlike a library catalogue card or the present DC (Dublin Core Metadata Standard) and was intended as a data exchange format. It was based on records describing projects, with persons and organisational units as attributes. However, it was soon realised that in practice this CERIF91 standard was inadequate: it was too rigid in format, did not handle repeating groups of information, was not multilingual / multi character set and did not represent in a sufficiently rich way the universe of interest. A new group of experts was convened and CERIF2000 was generated. Its essential features are: (a) it has the concept of objects or entities with attributes such as project, person, organisational unit; (b) it supports n:m relationships between them (and recursively on any of them) using 'linking relations' thus providing rich semantics including roles and time; (c) it is fully internationalised in language and character set; (d) it is extensible without prejudicing the core datamodel thus providing guaranteed interoperability at least at the core level but not precluding even richer intercommunication. It is designed for use both for data exchange (data file transfer) and for heterogeneous distributed query / result environments. With CERIF2004, minor improvements in consistency have been released. With CERIF2006 substantial improvements have been implemented with the model, concerning in particular the introduction of a so-called Semantic Layer, that makes the model flexible and scalable for application in very heterogeneous environments.

A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI) that uses the urn scheme, and does not imply availability of the identified resource. Both URNs (names) and URLs (locators) are URIs, and a particular URI may be a name and a locator at the same time. The Functional Requirements for Uniform Resource Names are described in RFC 1737. The URNs are part of a larger Internet information architecture which is composed of URNs, Uniform Resource Characteristics (URCs), and Uniform Resource Locators (URLs). Each plays a specific role: URNs are used for identification; URCs for including meta-information; URLs for locating or finding resources. (Excerpt from Wikipedia article: Uniform Resource Name)

information society

An information society is a society where the creation, distribution, use, integration and manipulation of information is a significant economic, political, and cultural activity. The aim of the information society is to gain competitive advantage internationally, through using information technology (IT) in a creative and productive way. The knowledge economy is its economic counterpart, whereby wealth is created through the economic exploitation of understanding. People who have the means to partake in this form of society are sometimes called digital citizens. This is one of many dozen labels that have been identified to suggest that humans are entering a new phase of society. The markers of this rapid change may be technological, economic, occupational, spatial, cultural, or some combination of all of these. Information society is seen as the successor to industrial society. Closely related concepts are the post-industrial society (Daniel Bell), post-fordism, post-modern society, knowledge society, telematic society, Information Revolution, liquid modernity, and network society (Manuel Castells).

geospatial data

A geographic information system (GIS), geographical information system, or geospatial information system is a system that captures, stores, analyzes, manages and presents data with reference to geographic location data. In the simplest terms, GIS is the merging of cartography, statistical analysis and database technology. GIS may be used in archaeology, geography, cartography, remote sensing, land surveying, public utility management, natural resource management, precision agriculture, photogrammetry, urban planning, emergency management, landscape architecture, navigation, aerial video and localized search engines.

Provenance, from the French provenir, "to come from", means the origin, or the source of something, or the history of the ownership or location of an object. The term was originally mostly used for works of art, but is now used in similar senses in a wide range of fields, including science and computing. (Excerpt from Wikipedia article: Provenance)

sword protocol

SWORD (Simple Web-service Offering Repository Deposit) is an interoperability standard that allows digital repositories to accept the deposit of content from multiple sources in different formats (such as XML documents) via a standardized protocol. In the same way that the HTTP protocol allows any web browser to talk to any web server, so SWORD allows clients to talk to repository servers. SWORD is a profile (specialism) of the Atom Publishing Protocol), but restricts itself solely to the scope of depositing resources into scholarly systems.

text mining

Text mining, sometimes alternately referred to as text data mining, roughly equivalent to text analytics, refers to the process of deriving high-quality information from text. High-quality information is typically derived through the devising of patterns and trends through means such as statistical pattern learning. Text mining usually involves the process of structuring the input text (usually parsing, along with the addition of some derived linguistic features and the removal of others, and subsequent insertion into a database), deriving patterns within the structured data, and finally evaluation and interpretation of the output. 'High quality' in text mining usually refers to some combination of relevance, novelty, and interestingness. Typical text mining tasks include text categorization, text clustering, concept/entity extraction, production of granular taxonomies, sentiment analysis, document summarization, and entity relation modeling (i.e., learning relations between named entities).

Solaris is a Unix operating system originally developed by Sun Microsystems. It superseded their earlier SunOS in 1993. Oracle Solaris, as it is now known, has been owned by Oracle Corporation since Oracle's acquisition of Sun in January 2010. Solaris is known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFS and Time Slider. Solaris supports SPARC-based and x86-based workstations and servers from Sun and other vendors, with efforts underway to port to additional platforms. Solaris is registered as compliant with the Single Unix Specification. Solaris was historically developed as proprietary software, then in June 2005 Sun Microsystems released most of the codebase under the CDDL license, and founded the OpenSolaris open source project. With OpenSolaris Sun wanted to build a developer and user community around the software. After the acquisition of Sun Microsystems in January 2010, Oracle decided to discontinue the OpenSolaris distribution and the development model. As a result, the OpenSolaris community forked the OpenIndiana project, as part of the Illumos Foundation. However, starting with Solaris 11, updates to the Solaris source code will still be distributed under the CDDL license, after full binary releases are made . Oracle will also begin a technology partner program, called Oracle Technology Network (OTN), to permit their industry partners access to the in-development Solaris source code.
