New York--e-Steel Corp., an online business-to-business marketplace for the steel industry, announced Tuesday that it plans to develop an integrated end-to-end electronic-commerce system for its members with the help of Fairfax, Va.-based webMethods and El Segundo, Calif.-based Computer Sciences Corp. The two IT companies will also develop a new open standard protocol--to be called SML (steel markup language)--specifically for the steel industry. This open standard will allow buyers and sellers to exchange data across different technology platforms. Steelmaker Dofasco Group will serve as the launch site for both the new e-commerce system and the SML protocol. The e-Steel marketplace launched in September 1999 and has about 1,000 members around the world, including 50 steel mills.
