Submission request to W3C (W3C Team Comment)

Hewlett-Packard Company hereby transmits to the Consortium the following specification, comprising the following document(s) attached hereto:
  1. Web Services Conversation Languages (WSCL), contained in attached zip-file together with three files for the graphics.

We ask that this submission request be known as WSCL.


This document specifies the Web Services Conversation Language WSCL. WSCL allows defining the abstract interfaces of web services, i.e. the business level conversations or public processes supported by a web service. WSCL specifies the XML documents being exchanged, and the allowed sequencing of these document exchanges. WSCL conversation definitions are themselves XML documents, and can therefore be interpreted by web services infrastructure and development tools. WSCL may be used in conjunction with other service description languages like WSDL; for example, to provide protocol binding information for abstract interfaces, or to specify the abstract interfaces supported by a concrete service.
