Microsoft will hold an open-design review to get industry feedback on new metadata extensions, allowing businesses to integrate Microsoft's line-of-business, data warehousing, and knowledge management environments. Also, the Meta Data Coalition (MDC) accepted the Open Information Model (OIM) as the metadata standard. Microsoft has led the industry in establishing shared metadata models for data warehousing, and these latest innovations provide fundamental technology to customers who realize the benefits of enterprise information portals, according to Douglas Leland, Microsoft's SQL Server marketing director. The OIM extensions are the result of extensive collaboration with industry partners and represent the first milestone in the effort initiated with the MDC in December 1998. The open-design review period for the new model extensions began in mid-July 1999 with the availability of preliminary specifications for knowledge description, business engineering, and business rule models. This phase of the open-design process is expected to conclude with an industry partner review in the fall of 1999, when updated specifications, final input, and early product demonstrations will be presented. The MDC OIM is based on technology developed by Microsoft and more than 20 leading industry partners. Microsoft transferred the right to maintain and evolve the OIM to MDC in December 1998.
