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)

open standard

An open standard is a standard that is publicly available and has various rights to use associated with it, and may also have various properties of how it was designed (e.g. open process). There is no single definition and interpretations vary with usage. The terms "open" and "standard" have a wide range of meanings associated with their usage. There are a number of definitions of open standards which emphasize different aspects of openness, including of the resulting specification, the openness of the drafting process, and the ownership of rights in the standard. The term "standard" is sometimes restricted to technologies approved by formalized committees that are open to participation by all interested parties and operate on a consensus basis. The definitions of the term "open standard" used by academics, the European Union and some of its member governments or parliaments such as Denmark, France, and Spain preclude open standards requiring fees for use, as do the New Zealand, South African and the Venezuelan governments. On the standard organisation side, the W3C ensures that its specifications can be implemented on a Royalty-Free (RF) basis. (Excerpt from Wikipedia article: Open standard)

The Open Document Format for Office Applications (also known as OpenDocument or ODF) is an XML-based file format for representing electronic documents such as spreadsheets, charts, presentations and word processing documents. While the specifications were originally developed by Sun Microsystems, the standard was developed by the OASIS Open Document Format for Office Applications (OpenDocument) TC - OASIS ODF TC, committee of the Organization for the Advancement of Structured Information Standards (OASIS) consortium and based on the XML format originally created and implemented by the office suite (see XML).

OpenID is an open standard that describes how users can be authenticated in a decentralized manner, obviating the need for services to provide their own ad hoc systems and allowing users to consolidate their digital identities. The OpenID protocol does not rely on a central authority to authenticate a user's identity. Moreover, neither services nor the OpenID standard may mandate a specific means by which to authenticate users, allowing for approaches ranging from the common (such as passwords) to the novel (such as smart cards or biometrics). The term OpenID may also refer to an ID as specified in the OpenID standard; these IDs take the form of a unique URL, and are managed by some 'OpenID provider' that handles authentication. OpenID authentication is now used and provided by several large websites. Providers include AOL, BBC, Google, IBM, MySpace, Orange, PayPal, VeriSign, LiveJournal, and Yahoo!

OpenURL is a standardized format (Z39.88) of Uniform Resource Locator (URL) intended to enable Internet users to more easily find a copy of a resource that they are allowed to access. Although OpenURL can be used with any kind of resource on the Internet, it is most heavily used by libraries to help connect patrons to subscription content. The OpenURL standard is designed to enable linking from information resources such as abstracting and indexing databases (sources) to library services (targets), such as academic journals, whether online or in printed or other formats. The linking is mediated by "link resolvers", or "link-servers", which parse the elements of an OpenURL and provide links to appropriate targets available through a library by the use of an OpenURL knowledge base. The source that generates an OpenURL is typically a bibliographic citation or bibliographic record in a database that indexes the information resources often found in libraries, such as articles, books, patents, etc. Examples of such databases include Ovid, Web of Science, SciFinder, Modern Languages Association Bibliography and Google Scholar. A target is a resource or service that helps satisfy a user's information needs. Examples of targets include full-text repositories, online journals, online library catalogs and other Web resources and services. The National Information Standards Organization (NISO) has developed OpenURL and its data container (the ContextObject) as American National Standards Institute (ANSI) standard Z39.88. On 22 June 2006, the Online Computer Library Center (OCLC) was named the maintenance agency for the standard. (Excerpt from Wikipedia article: OpenUrl)

The Open Provenance Model OPM is the result of the Provenance Challenge series that was initiated in May 2006, at the first IPAW workshop. OPM was originally crafted in a meeting held in Salt Lake City in August 2007. OPM v1.00 was released to the community in December 2007. The first OPM workshop in June 2008 involved some twenty participants discussing issues related to this specification, and led to a revised specification, referred to as OPM v1.01. From the outset, the original authors' intent has been to define a data model that is open from an inter-operability viewpoint but also with respect to the community of its contributors, reviewers and users. To ensure that these principles are adhered to, an "open source like" governance model for OPM was adopted in June 2009, which led to the development of OPM v1.1, the most recent version of the model, which went under a public revision process (Excerpt from this source)

OPML (Outline Processor Markup Language) is an XML format for outlines (defined as "a tree, where each node contains a set of named attributes with string values"). Originally developed by Radio UserLand as a native file format for an outliner application, it has since been adopted for other uses, the most common being to exchange lists of web feeds between web feed aggregators. The OPML specification defines an outline as a hierarchical, ordered list of arbitrary elements. The specification is fairly open which makes it suitable for many types of list data.

Open Service Interface Definitions (OSIDs) are programmatic interface specifications describing services. These interfaces are specified by the Open Knowledge Initiative (O.K.I.) to implement a Service-Oriented Architecture (SOA) to achieve interoperability among applications across a varied base of underlying and changing technologies. To preserve the investment in development, program logic is separated from underlying technologies through the use of software interfaces each of which defines a contract between a service consumer and a service provider. This separation is the basis of any valid SOA. While some methods define the service interface boundary at a protocol or server level, OSIDs place the boundary at the application level to effectively insulate the consumer from protocols, server identities, and utility libraries that are in the domain to a service provider resulting in software which is easier to develop, longer lasting, and usable across a wider array of computing environments.

The PMC Project P/Meta has this goal: the exchange of media items or objects between process stages and business entities would benefit significantly from a standard approach to structuring related information, either associated with the media in a separate data repository or embedded (wrapped) with it as electronic metadata. Seminal work is already being carried out by SMPTE on defining the Dynamic Metadata Dictionary, UMIDs, mapping of metadata into transports, and preparation of operational guidelines and engineering recommendations. Complementary work is proposed for the EBU to consider the adoption of a common exchange framework and format between members (and wider) which builds on SMPTE outputs and the additional insights provided by the BBC's Standard Media Exchange Framework.

persistent identifier

An identifier is any label that allows us to find a resource. One of the best-known identifiers is the International Standard Book Number (ISBN), a unique ten-digit number assigned to books and other publications. On the Internet the most widely known identifier is the Uniform Resource Locator (URL), which allows users to find a resource by listing a protocol, domain name and, in many cases, file location. A persistent identifier is, as the name suggests, an identifier that exists for a very long time. It should at the very least be globally unique and be used as a reference to the resource beyond the resource's lifetime. URLs, although useful, are not very persistent. They only provide a link to the resource's location at the moment in time they are cited, if the resource moves they no longer apply. The issue of 'linkrot' on the Internet (broken links to resources), along with the need for further interoperability has led to the search for more persistent identifiers for digital resources.

PHP is a general-purpose scripting language originally designed for web development to produce dynamic web pages. For this purpose, PHP code is embedded into the HTML source document and interpreted by a web server with a PHP processor module, which generates the web page document. It also has evolved to include a command-line interface capability and can be used in standalone graphical applications. PHP can be deployed on most web servers and as a standalone interpreter, on almost every operating system and platform free of charge. (Excerpt from Wikipedia article: PHP)
