The Open Applications Group, Inc. (OAGI), a non-profit industry consortium comprised of many of the stakeholders in the business software component interoperability arena, announced publication of a full set of XML Document Type Definition (DTD) files that define interoperability APIs. The group has built a common model for software application component interoperability over the last three years. The model is described in their Open Applications Group Integration Specification. OAGIS describes the major components, their integration dialogs, and the content of those dialogs for many key enterprise business applications, including financials, manufacturing, human resources, supply chain, and logistics. The DTDs necessary to define this integration content in XML have been published on the OAGI web site and are available for public access at: www.openapplications.org . The DTDs will be free of charge to download and use, but a license agreement will be enacted to maintain ownership of intellectual property.
