eXcelon Announces Support of Open Application Group's B2B Integration Specification

BURLINGTON, Mass.--(BUSINESS WIRE)--Aug. 23, 2000-- eXcelon Corporation (Nasdaq: EXLN - news), a leading provider of XML-based business-to-business (B2B) infrastructure solutions today announced full support for OAGIS, the Open Applications Group's standard for integration. By combining support for OAGIS with its unparalleled XML translation capabilities, eXcelon becomes the first vendor to enable organizations to build and deploy sophisticated B2B trading networks regardless of the type and number of different XML dialects used.

With support for multiple XML dialects, eXcelon will speed the adoption of B2B commerce by enabling organizations to deploy B2B trading networks without forcing partners, suppliers and customers to adopt a specific XML standard.

``eXcelon B2B solutions are an excellent example of how the OAGi specification can be implemented to create end-to-end business processes across multiple organizations,'' said David Connelly, president and CEO, Open Applications Group, Inc. ``By combining an internal information model based on the OAGi specification with XML translation and workflow capabilities, eXcelon demonstrates its ability to converge multiple XML standards, such as OAGIS and other leading B2B specifications.''

``eXcelon's B2B solutions provide a major step forward in enabling the vision of B2B electronic commerce -- connecting large numbers of organizations together to create collaborative trading networks that increase business efficiency and reduce costs,'' said Jean-Jacques Dubray, chief architect, eXcelon Corporation. ``By combining a state-of the-art workflow engine with the ability to interact with any XML-based standard, eXcelon makes it easy for organizations to share automated business processes between thousands of partners, suppliers and customers.''

eXcelon has developed B2B infrastructure solutions that enable organizations and digital marketplaces to connect to and dynamically interact with thousands of their partners, suppliers and customers over the Internet. eXcelon technology is 100 percent standards based, featuring complete support for any XML-based B2B standard, including OAGIS, RosettaNet, cXML, xCBL and ACORD.

The eXcelon B2B Integration Server features the industry's first business process interaction engine, which enables organizations to define and execute shared business processes of all types and complexities across multiple organizations. Business processes can be shared with any partner in the extranet community, regardless of their technical infrastructure or which B2B standards they support. By sharing automated business processes over the Internet, eXcelon removes a company's reliance on inefficient phone, fax and mail transactions, creating a more responsive, more efficient and more profitable company.
