The term Web service (WS) is either:
An interface description language or interface definition language (IDL), is a specification language used to describe a software component's application programming interface (API). IDLs describe an interface in a language-independent way, enabling communication between software components that do not share one language, for example, between those written in C++ and those written in Java.
The Web Services Business Process Execution Language (WS-BPEL), commonly known as BPEL, is an OASIS standard executable language for specifying actions within business processes with web services. Processes in BPEL export and import information by using web service interfaces exclusively.
Adobe ColdFusion is a commercial rapid web-application development computing platform created by J. J. Allaire in 1995. ColdFusion was originally designed to make it easier to connect simple HTML pages to a database. By version 2 (1996), it became a full platform that included an IDE in addition to a full scripting language.
Representational state transfer (REST) is a de-facto standard for a software architecture for interactive applications that typically use multiple Web services. In order to be used in a REST-based application, a Web Service needs to meet certain constraints; such a Web Service is called RESTful. A RESTful Web service is required to provide an application access to its Web resources in a textual representation and support reading and modification of them with a stateless protocol and a predefined set of operations. By being RESTful, Web Services provide interoperability between the computer systems on the internet that provide these services. REST offers an alternative to, for instance, SOAP as method of access to a Web Service.
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.
Apache Axis is an open-source, XML based Web service framework. It consists of a Java and a C++ implementation of the SOAP server, and various utilities and APIs for generating and deploying Web service applications. Using Apache Axis, developers can create interoperable, distributed computing applications. Axis development takes place under the auspices of the Apache Software Foundation.
Web Services Addressing (WS-Addressing) is a specification of transport-neutral mechanism that allows web services to communicate addressing information. It essentially consists of two parts: a structure for communicating a reference to a Web service endpoint, and a set of message addressing properties which associate addressing information with a particular message.
WS-Policy is a specification that allows web services to use XML to advertise their policies and for web service consumers to specify their policy requirements.
The Jakarta XML Web Services is a Jakarta EE API for creating web services, particularly SOAP services. JAX-WS is one of the Java XML programming APIs.
Apache Axis2 is a web service engine. It is a complete re-design and re-write of the widely used Apache Axis SOAP stack. Implementations of Axis2 are available in Java and C.
OWL-S is an ontology built on top of Web Ontology Language (OWL) by the DARPA DAML program. It replaces the former DAML-S ontology. "OWL-S is an ontology, within the OWL-based framework of the Semantic Web, for describing Semantic Web Services. It will enable users and software agents to automatically discover, invoke, compose, and monitor Web resources offering services, under specified constraints."
Service-oriented communications (SOC) technologies are designed to be easily used in the context of service-oriented architectures. These technologies are generally software based and are built more like a business application than a traditional PBX business communications system. Service-oriented communications systems allow their services to participate in business processes. They make their services available to other business applications within and SOA and allow for reuse of the services. The goal of service-oriented communications is to enable business environments to build communications into their business processes, enabling more streamlined collaboration among people within the business. It typically assumes that certain services are provided in the context of an SOA service provider. This is often in the form of a suite of web services, but may also be attached to other means of sharing the services such as an enterprise system bus (ESB).
Apache ODE is a software coded in Java as a workflow engine to manage business processes which have been expressed in the Web Services Business Process Execution Language (WS-BPEL) via a website. It was made by the Apache Software Foundation and released in a stable format on March 23, 2018. The software principally communicates with one or more Web services, sending and receiving messages, manipulating data and handling exceptions (errors) as defined by any given process. The engine is capable of running both long and short living processes to coordinate all the services that make up a service or application (orchestration).
WSML or Web Service Modeling Language is a formal language that provides a syntax and semantics for the Web Service Modeling Ontology (WSMO).
The Web Services Description Language 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, 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 similar to that of a type signature in a programming language.
JSON-WSP is a web service protocol that uses JSON for service description, requests and responses. It is inspired from JSON-RPC, but the lack of a service description specification with documentation in JSON-RPC sparked the design of JSON-WSP.
Semantic Annotations for WSDL and XML Schema (SAWSDL) is a 2007 published technical recommendation of W3C in the context of Semantic Web framework:
SMPTE ST 2071 is a suite of standards published by the Society of Motion Picture and Television Engineers (SMPTE) that define a framework, protocol, and method of service discovery for the control of objects within an Internet of Things. The standards focus on the interoperability and discoverability of objects within the network, and treat media as first-class citizen. The standard also describes a programming methodology that allows objects to describe their behaviors (features) to other objects over the network and allows objects to change their behavior dynamically at runtime. Application developers developing to the SMPTE ST 2071 standards focus on writing their applications to the behaviors they wish to support and not the object or class of object that implements those behaviors.
