Translation of "Webdiensteverbund" into English

A specification that defines a model and a set of messages for brokering trust and the federation of identity and authentication information across different trust realms. The WS-Federation specification identifies two sources of identity and authentication requests across trust realms: active requestors, such as Simple Object Access Protocol (SOAP)-enabled applications, and passive requestors, which are defined as Hypertext Transfer Protocol (HTTP) browsers that can support broadly supported versions of HTTP, for example, HTTP 1.1.
