The Global XML Web Services Architecture (GXA) was an announcement[1] by Microsoft in 2002 of several proposals for extensions to SOAP. Some of the components of GXA were developed into standards in combination with other companies, including IBM. Others were specific to Microsoft and have been superseded. Microsoft released a reference implementation of a part of GXA as Web Services Enhancements 1.0 SP1 for Microsoft .NET (WSE).

Components of GXA in WSE 1.0[edit]

WS-Security WS-Routing WS-Policy XML Infoset

GXA Future Directions[edit]

At the time of the GXA announcement, Microsoft listed further standards they were participating in developing:

Federated security: WS-Trust, WS-Privacy, WS-Federation, WS-SecureConversation, WS-Policy

Pervasive metadata and discovery: WS-Referral

Microsoft also announced they were working on distributed agreement (transaction) standards.
