From Web Services Glossary (2004-02-11)

A transport layer virtual circuit established between two programs for the purpose of communication. [RFC 2616]


From Web Services Glossary (2004-02-11)

To cause a desired change in state. Management systems may control the life cycle of manageable Web services or information flow such as messages.


From Web Services Glossary (2004-02-11)

A Web service conversation involves maintaining some state during an interaction that involves multiple messages and/or participants.


From Web Services Glossary (2004-02-11)

Data that is transferred to establish a claimed principal identity. [X.800]

delivery policy

From Web Services Glossary (2004-02-11)

A delivery policy is a policy that constrains the methods by which messages are delivered by the message transport.

digital signature

From Web Services Glossary (2004-02-11)

A value computed with a cryptographic algorithm and appended to a data object in such a way that any recipient of the data can use the signature to verify the data's origin and integrity. (See: data origin authentication service, data integrity service, digitized signature, electronic signature, signer.) [RFC 2828]


From Web Services Glossary (2004-02-11)

The act of locating a machine-processable description of a Web service-related resource that may have been previously unknown and that meets certain functional criteria. It involves matching a set of functional and other criteria with a set of resource descriptions. The goal is to find an appropriate Web service-related resource.

discovery service

From Web Services Glossary (2004-02-11)

A discovery service is a service that enables agents to retrieve Web services-related resource description.


From Web Services Glossary (2004-02-11)

Any data that can be represented in a digital form. [UeB Glossary]


From Web Services Glossary (2004-02-11)

A domain is an identified set of agents and/or resources that is subject to the constraints of one of more policies.

electronic data interchange (EDI)

From Web Services Glossary (2004-02-11)

The automated exchange of any predefined and structured data for business among information systems of two or more organizations. [ISO/IEC 14662]


From Web Services Glossary (2004-02-11)

Cryptographic transformation of data (called "plaintext") into a form (called "ciphertext") that conceals the data's original meaning to prevent it from being known or used. If the transformation is reversible, the corresponding reversal process is called "decryption", which is a transformation that restores encrypted data to its original state. [RFC 2828]

end point

From Web Services Glossary (2004-02-11)

An association between a binding and a network address, specified by a URI, that may be used to communicate with an instance of a service. An end point indicates a specific location for accessing a service using a specific protocol and data format. [WSD Reqs]


From Web Services Glossary (2004-02-11)

An agent that terminates a message on an inbound interface with the intent of presenting it through an outbound interface as a new message. Unlike a proxy, a gateway receives messages as if it were the final receiver for the message. Due to possible mismatches between the inbound and outbound interfaces, a message may be modified and may have some or all of its meaning lost during the conversion process. For example, an HTTP PUT has no equivalent in SMTP.

Note: a gateway may or may not be a SOAP node; however a gateway is never a SOAP intermediary, since gateways terminate messages and SOAP intermediaries relay them instead. Being a gateway is typically a permanent role, whilst being a SOAP intermediary is message specific.


From Web Services Glossary (2004-02-11)

Property of an interaction whose results and side-effects are the same whether it is done one or multiple times. [RFC 2616]

Safe interactions are inherently idempotent.


From Web Services Glossary (2004-02-11)

An identifier is an unambiguous name for a resource.

initial SOAP sender

From Web Services Glossary (2004-02-11)

The SOAP sender that originates a SOAP message at the starting point of a SOAP message path.


From Web Services Glossary (2004-02-11)

Assuring information will not be accidentally or maliciously altered or destroyed. [NSA Glossary]

loose coupling

From Web Services Glossary (2004-02-11)

Coupling is the dependency between interacting systems. This dependency can be decomposed into real dependency and artificial dependency:

  1. Real dependency is the set of features or services that a system consumes from other systems. The real dependency always exists and cannot be reduced.

  2. Artificial dependency is the set of factors that a system has to comply with in order to consume the features or services provided by other systems. Typical artificial dependency factors are language dependency, platform dependency, API dependency, etc. Artificial dependency always exists, but it or its cost can be reduced.

Loose coupling describes the configuration in which artificial dependency has been reduced to the minimum.

manageable service

From Web Services Glossary (2004-02-11)

A Web service becomes a manageable service with additional semantics, policy statements, and monitoring and control (or management) capabilities (exposed via a management interface) all for the purpose of managing the service.
