[June 30, 2000] XIOP: Corba GIOP using XML1.0 +HTTP1.1. Anders W. Tell (Financial Toolsmiths AB) recently announced work on a new protocol XIOP. "I'm working on a protocol which is not directly new, OMG GIOP. However this version uses XML 1.0 as encoding format and HTTP/1.1 as primary protocol. It is also possible to send raw CDR encoded IIOP messages. One notable feature is that all encodings (including CDR) are based on a Grove-like information model called 'Gren' -- Swedish for 'tree branch'." The XIOP Web-Site (on Sourceforge) was opened to the public 2000-04-02. The development site "is open to discussions on XIOP, an open and freely available Corba EISOP (Environment-Specific Inte-ORB Protocol), and a GIOP compliant mapping using HTTP 1,1 as communication protocol and XML 1.0 as content encoding. Use it as XML-RPC and get an standardised and open distributed object environment for free. The XIOP specification allows for different encodings to be passed over the wire, including IIOP (CDR) and XML. The encoding framework is based on 'Gren', which is a reformulation of Groves information model..." Recently, an XIOP Viewer was added to the site. The development site specification page also provides references to the XIOP documents and white papers, the multi-part specification, and rationale ("Why XIOP is valid as XML-RPC"). There is also an XIOP mailing list.
