HATEOAS
Hypermedia as the engine of application state (HATEOAS) is a constraint of the REST software architectural style that distinguishes it from other network architectural styles. With HATEOAS, a client interacts with a network application whose application servers provide information dynamically through hypermedia. A REST client needs little to no prior knowledge about how to interact with an application or server beyond a generic understanding of hypermedia. By contrast, clients and servers in Common Object Request Broker Architecture (CORBA) interact through a fixed interface shared through documentation or an interface description language (IDL). The restrictions imposed by HATEOAS decouple client and server. This enables server functionality to evolve independently. The term was coined in 2000 by Roy Fielding in his doctoral dissertation. Example A user-agent makes an HTTP request to a REST API through an entry point URL. All subsequent requests the user-agent may ma ...

Representational State Transfer
REST (Representational State Transfer) is a software architectural style that was created to describe the design and guide the development of the architecture for the World Wide Web. REST defines a set of constraints for how the architecture of a distributed, Internet-scale hypermedia system, such as the Web, should behave. The REST architectural style emphasises uniform API, interfaces, independent deployment of Software component, components, the scalability of interactions between them, and creating a Multitier architecture, layered architecture to promote caching to reduce user-perceived latency (engineering), latency, enforce computer security, security, and encapsulate legacy systems. REST has been employed throughout the software industry to create stateless protocol, stateless, reliable, web application, web-based applications. An application that adheres to the #Architectural constraints, REST architectural constraints may be informally described as ''RESTful'', althoug ...

Link Relation
A link relation is a descriptive attribute attached to a hyperlink in order to define the type of the link, or the relationship between the source and destination resources. The attribute can be used by automated systems, or can be presented to a user in a different way. In HTML these are designated with the attribute on , , or elements. Example uses include the standard way of referencing CSS, , which indicates that the external resource linked to with the attribute is a stylesheet, so a web browser will generally fetch this file to render the page. Another example is for the popular favicon icon. Link relations are used in some microformats (e.g. for tagging), in XHTML Friends Network (XFN), and in the Atom standard, in XLink, as well as in HTML. Standardized link relations are one of the foundations of HATEOAS as they allow the user agent to understand the meaning of the available state transitions in a Representational State Transfer system.

Htmx
htmx (also stylized as HTMX) is an open-source front-end JavaScript library that extends HTML with custom attributes that enable the use of AJAX directly in HTML and with a hypermedia-driven approach. These attributes allow for the dynamic definition of a web page directly in HTML and CSS, without the need for writing additional JavaScript. These attributes allows tasks that traditionally required writing JavaScript to be done completely with HTML. The library was created by Carson Gross as a new version of intercooler.js. The library supports communication with the server using standard HTTP methods and simplifies inserting server responses (usually text or HTML fragments) into designated parts of the web page without having to redraw the entire page. This in turn allows for similar behavior to what can be achieved with reconciliation behavior in virtual DOMs. History htmx has its roots in intercooler.js, a frontend library created by Carson Gross in 2013. The library a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypertext Application Language
Hypertext Application Language (HAL) is a convention for defining hypermedia such as links to external resources within JSON or XML code. It is documented in an Internet Draft (a "work in progress"), with the latest version 11 published the 10th of October 2023. The standard was initially proposed in June 2012, specifically for use with JSON, and has since become available in two variations, JSON and XML. The two associated MIME types are application/hal+xml and application/hal+json. HAL was created to be simple to use and easily applicable across different domains by avoiding the need to impose any requirements on how the project be structured. Maintaining this minimal impact approach, HAL has enabled developers to create general-purpose libraries which can be incorporated on any API that uses HAL. APIs that adopt HAL simplify the use of open source libraries and make it possible to interact with the API using JSON or XML. The alternative would be having to develop a proprietary ...

Hypermedia
Hypermedia, an extension of hypertext, is a nonlinear medium of information that includes graphics, audio, video, plain text and hyperlinks. This designation contrasts with the broader term ''multimedia'', which may include non-interactive linear presentations as well as hypermedia. The term was first used in a 1965 article written by Ted Nelson. Hypermedia is a type of multimedia that features interactive elements, such as hypertext, buttons, or interactive images and videos, allowing users to navigate and engage with content in a non-linear manner. The World Wide Web is a classic example of hypermedia to access web content, whereas a conventional Movie theatre, cinema presentation is an example of standard multimedia, due to its inherent linearity and lack of interactivity via hyperlinks. The first hypermedia work was, arguably, the Aspen Movie Map. Bill Atkinson's HyperCard popularized hypermedia writing, while a variety of literary hypertext and non-fiction hypertext works, de ...

Roy Fielding
Roy Thomas Fielding (born 1965) is an American computer scientist, one of the principal authors of the HTTP specification and the originator of the Representational State Transfer (REST) architectural style. He is an authority on computer network architecture and co-founded the Apache HTTP Server project. Fielding works as a senior principal scientist at Adobe Systems in San Jose, California. Biography Fielding was born in 1965 in Laguna Beach, California. He describes himself as "part Maori, Kiwi, Yank, Irish, Scottish, British, and California beach bum". In 1999, the Massachusetts Institute of Technology (MIT) Technology Review TR100 named him one of the top 100 innovators in the world under the age of 35. In 2000, he received his doctorate from the University of California, Irvine.

Distributed Computing
Distributed computing is a field of computer science that studies distributed systems, defined as computer systems whose inter-communicating components are located on different networked computers. The components of a distributed system communicate and coordinate their actions by passing messages to one another in order to achieve a common goal. Three significant challenges of distributed systems are: maintaining concurrency of components, overcoming the lack of a global clock, and managing the independent failure of components. When a component of one system fails, the entire system does not fail. Examples of distributed systems vary from SOA-based systems to microservices to massively multiplayer online games to peer-to-peer applications. Distributed systems cost significantly more than monolithic architectures, primarily due to increased needs for additional hardware, servers, gateways, firewalls, new subnets, proxies, and so on. Also, distributed systems are prone to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Services Description Language
The Web Services Description Language (WSDL ) is an XML-based interface description language that is used for describing the functionality offered by a web service. The acronym is also used for any specific WSDL description of a web service (also referred to as a ''WSDL file''), which provides a machine-readable description of how the service can be called, what parameters it expects, and what data structures it returns. Therefore, its purpose is roughly like a type signature in a programming language. The latest version of WSDL, which became a W3C recommendation in 2007, is WSDL 2.0. The meaning of the acronym has changed from version 1.1 where the "D" stood for "Definition". Description The WSDL describes services as collections of network Communication endpoint, endpoints, or Port (computer networking), ports. The WSDL specification provides an XML File format, format for documents for this purpose. The abstract definitions of ports and messages are separated from their conc ...

Universal Description Discovery And Integration
Web Services Discovery provides access to software systems over the Internet using standard protocols. In the most basic scenario there is a ''Web Service Provider'' that publishes a service and a ''Web Service Consumer'' that uses this service. Web Service Discovery is the process of finding suitable web services for a given task. Publishing a web service involves creating a software artifact and making it accessible to potential consumers. Web service providers augment a service endpoint interface with an interface description using the Web Services Description Language (WSDL) so that a consumer can use the service. Universal Description, Discovery, and Integration (UDDI) is an XML-based registry for business internet services. A provider can explicitly register a service with a ''Web Services Registry'' such as UDDI or publish additional documents intended to facilitate discovery such as Web Services Inspection Language (WSIL) documents. The service users or consumers can sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
