Revolving around .Net servers such as BizTalk, SharePoint Portal Server and Project Server 2003, Microsofts PPI will emphasize security, compliance with industry standards and interoperability with non-Microsoft software, eWEEK.com was told. "With all of the other solutions and platforms out there, all solutions arent going to be 100 percent .Net. People will be surprised to see how interoperable [Microsoft] can really be," Johnson said.But Johnson described PPI as "more a set of prescriptive technologies than an architectural platform."Also on Tuesday, the company launched a Plant-to-Enterprise Interoperability initiative that calls for Microsoft to support ISA-95 standards, in addition to the previously supported OPC shop floor standard. Johnson noted that Microsofts BizTalk also supports RosettaNet, an architectural standard for the electronics and chemical industries. In an earlier announcement, Microsoft said that that it was teaming with more than 30 retail and hospitality device makers to build retail solutions around another environment, Windows Embedded for POS (point of service).
