MONTEREY, Calif.--(BUSINESS WIRE)--July 18, 2000

Invisible Worlds, Inc. announces the launch of BXXP.org, a community web site for developers. Invisible Worlds, Inc. of Petaluma, CA, the primary sponsor of the web site, made the announcement today at the O'Reilly Open Source Conference meeting in Monterey. BXXP stands for Blocks eXtensible eXchange Protocol, which is a component of the Blocks(TM) architecture developed by Invisible Worlds co-founder Marshall Rose. BXXP, an XML-based protocol, is currently under review by a working group of the Internet Engineering Task Force (IETF), a crucial step in the adoption process for Internet standards. The mission for the new web site is to facilitate and promote the development and use of BXXP.

Kris Magnusson, Director of Developer Relations, at Invisible Worlds, said, "BXXP is a robust and innovative solution that solves an enormous number of technical problems. It is a great new protocol framework for Internet applications and will have immeasurable benefits for Internet communications. BXXP.org is already hosting community projects related to BXXP or to the Blocks(TM) architecture, and will provide the infrastructure necessary to get BXXP-related projects up and running."

Designed to help facilitate communication between members of the open source community, BXXP.org helps developers to host their own BXXP projects and participate in other projects as well. BXXP.org provides a collaborative software development environment that will include source control, bug tracking, and project administration. In addition, the site will maintain technical information related to the BXXP framework and will provide easy downloads for developers, as well as a complete list of BXXP-related Internet drafts. An automated FAQ system is another benefit for developers at the site, as well as a database of community members, project mailing lists, and project administration facilities.

BXXP is a collection of techniques used by experienced application protocol designers since the early 1980s. BXXP uses XML to frame messages. BXXP exchanges messages asynchronously, so applications won't need to finish one conversation before starting another.
