XML Schema Validation Process for CORE.GOV



KC Morris, Boonserm Kulvatunyou, Simon P. Frechette, Joshua Lubell, Puja Goyal


Many integration projects today rely on shared semantic models based on standards represented using Extensible Mark up Language (XML) technologies. Shared semantic models typically evolve and require maintenance. In addition, to promote interoperability and reduce integration costs, the shared semantics should be reused as much as possible. The GSA Component Organization and Registration Environment (CORE.GOV) initiative is an effort to promote the sharing and reuse of components to reduce the acquisition costs of software needed by government. To be effective, CORE.GOV components must be consistent and valid in terms of agreed upon standards and guidelines. In this paper, we describe an activity model for validation of shared semantic models that is coherent and supports efficient enterprise integration. We then use this activity model to frame our research and the development of tools to support those activities. Overviews of these supporting tools are described primarily in the context of the W3C XML Schema. At the present, we focus our work on the W3C XML Schema as the representation of choice, due to its extensive adoption by industry. We believe this validation model and associated tools could serve as the basis for a CORE.GOV validation and acceptance process.
