Richardson Maturity Model
The Richardson Maturity Model (RMM) is a maturity model suggested in 2008 by Leonard Richardson which classifies Web APIs based on their adherence and conformity to each of the model's four levels. The aim of the research of the model as stated by the author was to find out the relationship between the constraints of REST and other forms of web services. It divides the principle parts of RESTful design into three steps: resource identification (URI), HTTP verbs, and hypermedia controls (e.g. hyperlinks). The RMM has been cited useful in evaluating the quality of particularly RESTful Web API design (even though it is not restricted to REST alone) and criticized for not addressing how a system could achieve the highest maturity levels of the model as well as for considering a limited number of quality attributes. Overview The RMM can be employed to determine how well a Web service architecture adheres to REST principles. It categorizes a Web API into four levels (from 0 to 3) w ...

Maturity Model
Maturity is a measurement of the ability of an organization for continuous improvement in a particular discipline (as defined in O-ISM3 ). The higher the maturity, the higher will be the chances that incidents or errors will lead to improvements either in the quality or in the use of the resources of the discipline as implemented by the organization. Most maturity models assess qualitatively people/culture, processes/structures, and objects/technology. Two approaches for implementing maturity models exist. With a top-down approach, such as proposed by Becker et al., a fixed number of maturity stages or levels is specified first and further corroborated with characteristics (typically in form of specific assessment items) that support the initial assumptions about how maturity evolves. When using a bottom-up approach, such as suggested by Lahrmann et al., distinct characteristics or assessment items are determined first and clustered in a second step into maturity levels to induce a ...

Web API
A web API is an application programming interface for either a web server or a web browser. It is a web development concept, usually limited to a web application's client-side (including any web frameworks being used), and thus usually does not include web server or browser implementation details such as SAPIs or APIs unless publicly accessible by a remote web application. Server side A server-side web API is a programmatic interface consisting of one or more publicly exposed endpoints to a defined request–response message system, typically expressed in JSON or XML, which is exposed via the web—most commonly by means of an HTTP-based web server. Mashups are web applications which combine the use of multiple server-side web APIs. Webhooks are server-side web APIs that take input as a Uniform Resource Identifier (URI) that is designed to be used like a remote named pipe or a type of callback such that the server acts as a client to dereference the provided URI and trigger an ev ...

HTTP Verbs
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 t ...

HATEOAS
Hypermedia as the Engine of Application State (HATEOAS) is a constraint of the REST application architecture that distinguishes it from other network application architectures. 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. Example A user-agent that implements HTTP makes an HTTP request of a REST API through a simple URL. All subsequent requests the user-agent may make are discovered inside the responses to each request. The med ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HTML Link
In computing, a hyperlink, or simply a link, is a digital reference to data that the user can follow or be guided by clicking or tapping. A hyperlink points to a whole document or to a specific element within a document. Hypertext is text with hyperlinks. The text that is linked from is known as anchor text. A software system that is used for viewing and creating hypertext is a ''hypertext system'', and to create a hyperlink is ''to hyperlink'' (or simply ''to link''). A user following hyperlinks is said to ''navigate'' or ''browse'' the hypertext. The document containing a hyperlink is known as its source document. For example, in an online reference work such as Wikipedia or Google, many words and terms in the text are hyperlinked to definitions of those terms. Hyperlinks are often used to implement reference mechanisms such as tables of contents, footnotes, bibliographies, indexes, letters, and glossaries. In some hypertext, hyperlinks can be bidirectional: they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plain Old XML
Plain Old XML (POX) is the basic XML, sometimes mixed in with other, blendable specifications like XML Namespaces, Dublin Core, XInclude and XLink. This contrasts with complicated, multilayered XML specifications like those for web services or RDF. The term may have been derived from or inspired by the expression plain old telephone service (POTS) and, similarly Plain Old Java Object (POJO). An interesting question is how POX relates to XML Schema. On the one hand, POX is completely compatible with XML Schema. However, many POX users eschew XML Schema to avoid the poor or inconsistent quality of XML Schema-to-Java tools. POX is complementary to REST: REST refers to a communication pattern, while POX refers to an information format style. The primary competitors to POX are more strictly-defined XML-based information formats such as RDF and SOAP section 5 encoding, as well as general non-XML information formats such as JSON JSON (JavaScript Object Notation, pronounced ; ...

SOAP
Soap is a salt of a fatty acid used in a variety of cleansing and lubricating products. In a domestic setting, soaps are surfactants usually used for washing, bathing, and other types of housekeeping. In industrial settings, soaps are used as thickeners, components of some lubricants, and precursors to catalysts. When used for cleaning, soap solubilizes particles and grime, which can then be separated from the article being cleaned. In hand washing, as a surfactant, when lathered with a little water, soap kills microorganisms by disorganizing their membrane lipid bilayer and denaturing their proteins. It also emulsifies oils, enabling them to be carried away by running water. Soap is created by mixing fats and oils with a base. A similar process is used for making detergent which is also created by combining chemical compounds in a mixer. Humans have used soap for millennia. Evidence exists for the production of soap-like materials in ancient Babylon around 2800 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
