A web service (WS) is either:
The XML Metadata Interchange (XMI) is an Object Management Group (OMG) standard for exchanging metadata information via Extensible Markup Language (XML).
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.
The WS-I Basic Profile, a specification from the Web Services Interoperability industry consortium (WS-I), provides interoperability guidance for core Web Services specifications such as SOAP, WSDL, and UDDI. The profile uses Web Services Description Language (WSDL) to enable the description of services as sets of endpoints operating on messages.
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.
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.
The Windows Communication Foundation (WCF), previously known as Indigo, is a free and open-source runtime and a set of APIs in the .NET Framework for building connected, service-oriented applications.
A web API is an application programming interface (API) for either a web server or a web browser. As a web development concept, it can be related to a web application's client side. A server-side web API consists of one or more publicly exposed endpoints to a defined request–response message system, typically expressed in JSON or XML by means of an HTTP-based web server. A server API (SAPI) is not considered a server-side web API, unless it is publicly accessible by a remote web application.
In the Web service context the term endpoint received a formal definition with the W3C recommendation "WSDL 2.0" of 2007,
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.
The Devices Profile for Web Services (DPWS) defines a minimal set of implementation constraints to enable secure web service messaging, discovery, description, and eventing on resource-constrained devices.
Web Services Interoperability Technology (WSIT) is an open-source project started by Sun Microsystems to develop the next-generation of Web service technologies. It provides interoperability between Java Web Services and Microsoft's Windows Communication Foundation (WCF).
Apache Axis2 is a web service engine. It is a redesign and re-write of the widely used Apache Axis SOAP stack. Implementations of Axis2 are available in Java and C.
The Microsoft Open Specification Promise is a promise by Microsoft, published in September 2006, to not assert its patents, in certain conditions, against implementations of a certain list of specifications.
The Governance Interoperability Framework (GIF) is an open, standards-based specification and set of technologies that describes and promotes interoperability among components of a service-oriented architecture (SOA). GIF integrates SOA ecosystem technologies to achieve heterogeneous service lifecycle governance and is supported by Hewlett-Packard Company and by GIF partners.
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).
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.
IBM WebSphere Service Registry and Repository (WSRR) is a service registry for use in a Service-oriented architecture.
gSOAP is a C and C++ software development toolkit for SOAP/XML web services and generic XML data bindings. Given a set of C/C++ type declarations, the compiler-based gSOAP tools generate serialization routines in source code for efficient XML serialization of the specified C and C++ data structures. Serialization takes zero-copy overhead.
