XDI
XDI (short for "eXtensible Data Interchange") is a semantic data interchange format and protocol under development by the OASIS (organization), OASIS]XDI Technical Committee The name comes from the addressable graph model XDI uses: every node in the XDI graph is its own Resource Description Framework, RDF graph that is uniquely addressable. Background The main features of XDI are: the ability to link and nest RDF graphs to provide context; full addressability of all nodes in the graph at any level of context; representation of XDI operations as graph statements so authorization can be built into the graph; a standard JSON serialization format; and a simple ontology language for defining shared semantics using XDI dictionary services. The XDI protocol is based on an exchange of XDI messages which themselves are XDI graphs. Since the semantics of each message is fully contained within the XDI graph of that message, the XDI protocol can be bound to multiple transport protocols. The XD ...

Link Contract
{{Unreferenced, date=January 2022 A link contract is an approach to data control in a distributed data sharing network. Link contracts are a key feature of the XDI specifications under development at OASIS. In XDI, a link contract is a machine-readable XDI document that governs the sharing of other XDI data. Unlike a conventional Web link, which is essentially a one-dimensional "string" that "pulls" a linked document into a browser, a link contract is a graph of metadata (typically in JSON) that can actively control the flow of data from a publisher to a subscriber by either "push" or "pull". The flow is controlled by the terms of the contract, which can be as flexible and extensible as real-world contracts, i.e., link contracts can govern: * Identification: Who are the parties to the contract? * Authority: Who controls the data being shared via the contract? * Authentication: How will each party prove its identity to the other? * Authorization: Who has what access rights and pr ...

I-name
I-names are one form of an XRI — an OASIS open standard for digital identifiers designed for sharing resources and data across domains and applications. XRI Technical Committee (14 November 2005) I-names are XRIs intended to be as easy as possible for people to remember and use. For example, a personal i-name could be ''=Mary'' or ''=Mary.Jones''. An organizational i-name could be ''@Acme'' or ''@Acme.Corporation''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I-number
i-numbers are a type of Internet identifier designed to solve the problem of how any web resource can have a persistent identity that never changes even when the web resource moves or changes its human-friendly name. For example, if a web page has an i-number, and links to that page use the i-number, then those links will not break even if the page is renamed, the website containing the page is completely reorganized, or the page is moved to another website. Conceptually, an i-number is similar to an IP address, except i-numbers operate at a much higher level of abstraction in Internet addressing architecture. The other key difference is that i-numbers are persistent, i.e., once they are assigned to a resource, they are never reassigned. By contrast, IP addresses are constantly reassigned, e.g., your computer may have a different IP address every time it connects to the Internet. Technically, an i-number is one form of an extensible resource identifier (XRI) — an abstract stru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OASIS (organization)
The Organization for the Advancement of Structured Information Standards (OASIS; ) is a nonprofit consortium that works on the development, convergence, and adoption of open standards for cybersecurity, blockchain, Internet of things (IoT), emergency management, cloud computing, legal data exchange, energy, content technologies, and other areas. History OASIS was founded under the name "SGML Open" in 1993. It began as a trade association of Standard Generalized Markup Language (SGML) tool vendors to cooperatively promote the adoption of SGML through mainly educational activities, though some amount of technical activity was also pursued including an update of the CALS Table Model specification and specifications for fragment interchange and entity management. In 1998, with the movement of the industry to XML, SGML Open changed its emphasis from SGML to XML, and changed its name to OASIS Open to be inclusive of XML and reflect an expanded scope of technical work and standa ...

Social Web
The social web is a set of social relations that link people through the World Wide Web. The social web encompasses how websites and software are designed and developed in order to support and foster social interaction. These online social interactions form the basis of much online activity including online shopping, education, gaming and social networking services. The social aspect of Web 2.0 communication has been to facilitate interaction between people with similar tastes. These tastes vary depending on who the target audience is, and what they are looking for. For individuals working in the public relation department, the job is consistently changing and the impact is coming from the social web. The influence held by the social network is large and ever changing. As people's activities on the Web and communication increase, information about their social relationships become more available. Social networking services such as Facebook enable people and organizations to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resource Description Framework
The Resource Description Framework (RDF) is a World Wide Web Consortium (W3C) standard originally designed as a data model for metadata. It has come to be used as a general method for description and exchange of graph data. RDF provides a variety of syntax notations and data serialization formats with Turtle (Terse RDF Triple Language) currently being the most widely used notation. RDF is a directed graph composed of triple statements. An RDF graph statement is represented by: 1) a node for the subject, 2) an arc that goes from a subject to an object for the predicate, and 3) a node for the object. Each of the three parts of the statement can be identified by a URI. An object can also be a literal value. This simple, flexible data model has a lot of expressive power to represent complex situations, relationships, and other things of interest, while also being appropriately abstract. RDF was adopted as a W3C recommendation in 1999. The RDF 1.0 specification was published in 2004, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JSON
JSON (JavaScript Object Notation, pronounced ; also ) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays (or other serializable values). It is a common data format with diverse uses in electronic data interchange, including that of web applications with servers. JSON is a language-independent data format. It was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data. JSON filenames use the extension .json. Any valid JSON file is a valid JavaScript (.js) file, even though it makes no changes to a web page on its own. Douglas Crockford originally specified the JSON format in the early 2000s. He and Chip Morningstar sent the first JSON message in April 2001. Naming and pronunciation The 2017 international standard (ECMA-404 and ISO/IEC 21778:2017) specifies "Pronounced , as in 'Jason and The ...

HTTP
The Hypertext Transfer Protocol (HTTP) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a mouse click or by tapping the screen in a web browser. Development of HTTP was initiated by Tim Berners-Lee at CERN in 1989 and summarized in a simple document describing the behavior of a client and a server using the first HTTP protocol version that was named 0.9. That first version of HTTP protocol soon evolved into a more elaborated version that was the first draft toward a far future version 1.0. Development of early HTTP Requests for Comments (RFCs) started a few years later and it was a coordinated effort by the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C), with work later moving to ...

HTTPS
Hypertext Transfer Protocol Secure (HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP). It is used for secure communication over a computer network, and is widely used on the Internet. In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS) or, formerly, Secure Sockets Layer (SSL). The protocol is therefore also referred to as HTTP over TLS, or HTTP over SSL. The principal motivations for HTTPS are authentication of the accessed website, and protection of the privacy and integrity of the exchanged data while in transit. It protects against man-in-the-middle attacks, and the bidirectional encryption of communications between a client and server protects the communications against eavesdropping and tampering. The authentication aspect of HTTPS requires a trusted third party to sign server-side digital certificates. This was historically an expensive operation, which meant fully authenticated HTTPS connections were usually found only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XMPP
Extensible Messaging and Presence Protocol (XMPP, originally named Jabber) is an open communication protocol designed for instant messaging (IM), presence information, and contact list maintenance. Based on XML (Extensible Markup Language), it enables the near-real-time exchange of structured data between two or more network entities. Designed to be extensible, the protocol offers a multitude of applications beyond traditional IM in the broader realm of message-oriented middleware, including signalling for VoIP, video, file transfer, gaming and other uses. Unlike most commercial instant messaging protocols, XMPP is defined in an open standard in the application layer. The architecture of the XMPP network is similar to email; anyone can run their own XMPP server and there is no central master server. This federated open system approach allows users to interoperate with others on any server using a 'JID' user account, similar to an email address. XMPP implementations can be deve ...

TCP/IP
The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the set of communication protocols used in the Internet and similar computer networks according to functional criteria. The foundational protocols in the suite are the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), and the Internet Protocol (IP). In the development of this networking model, early versions of it were known as the Department of Defense (DoD) model because the research and development were funded by the United States Department of Defense through DARPA. The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed, and received. This functionality is organized into four abstraction layers, which classify all related protocols according to each protocol's scope of networking. An implementation of the layers for a particular application forms a protocol stack. From lowest to high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
