Web Services Flow Language
open-in-new
<p>Web Services Flow Language 1.0 (WSFL) was an <a href="/facts/XML/clNgUfWk">XML</a> programming language proposed by <a href="/facts/IBM/QszA7nwd">IBM</a> in 2001 for describing <a href="/facts/Web_service/qxrwqB3D">Web services</a> compositions. Language considered two types of compositions. The first type was for describing business processes as a collection of web services and the second was for describing interactions between partners. WSFL was proposed to be layered on top of <a href="/facts/Web_Services_Description_Language/tQPIot4A">Web Services Description Language</a>. </p><p>In 2003 IBM and Microsoft combined WSFL and <a href="/facts/Xlang/HUmdnJEb">Xlang</a> to BPEL4WS and submitted it to <a href="/facts/OASIS_(organization)/a2r8y7tX">OASIS</a> for standardization. Oasis published BPEL4WS as <a href="/facts/WS-BPEL/HUmdnJEb">WS-BPEL</a> to properly fit the naming of other <a href="/facts/WS-*/x4qDdmTj">WS-*</a> standards. </p>
