Researchers at NASA's Johnson Space Center have developed a flexible Web service application that facilitates data modeling in business cases where requirements are incomplete or constantly evolving. Key elements of the software include a schema-less database for modeling flexibility, a core service layer architecture for business rule and database encapsulation, an XIM application library, a custom MVC framework, and a Flex® software development tool. Since the XIM core is domain-independent, each application is an embodiment of XIM with its own business rules and additions to the core service layer. This software may be released for U.S. Government purposes only.

  • Robust: Provides a data modeling solution where business or technical requirements are incomplete or constantly evolving
  • Flexible: Allows a user to model entities at a generic top-level by not requiring values for all nodes at every level through the use of the pre-defined composition, classification, and category hierarchies built into the software
  • Cost-effective: Eliminates the need for a resource intensive reconciliation process to compile multiple sets of complex data
  • Economical: Improves configuration management of data with one centralized database
  • Efficient: Reduces data entry time by taking advantage of XIM's inheritance of values, validation, and synchronization features


  • Complex data modeling and design applications where requirements are dynamic or incomplete
