Engineering BetterData Models
UDDL Data Modeler
UDDL Modeler is a standards-based development environment for creating, managing, and validating interoperable data models across complex defense software systems.
Interoperability starts with standardized data. UDDL Modeler, built on the Open Group’s Open Universal Domain Description Language (Open UDDL), provides a trusted environment for developing and validating interoperable data models that simplify integration, support standards compliance, and help programs deliver connected, mission-ready systems.
Everything in One Environment
Modern defense programs require more than standardized data models. They need efficient workflows, built-in standards compliance, and the ability to generate the engineering artifacts that support integration across complex systems. UDDL Modeler brings these capabilities together in a single, standards-based environment, helping engineering teams simplify development, reduce manual effort, and improve collaboration throughout the digital engineering lifecycle. From intuitive model creation to automated conformance testing and artifact generation, UDDL Modeler enables faster development, greater consistency, and more confident delivery of interoperable, mission-ready systems.
Intuitive
Workflow
Complex data models require more than powerful tools. They require clear visibility. UDDL Modeler combines intuitive editors, automated diagrams, and context-aware views to simplify the development and management of large Domain-Specific Data Models (DSDMs). Engineers can quickly visualize relationships, maintain context, and work more efficiently without navigating multiple layers of properties or disconnected model views. The result is faster development, improved collaboration, and greater confidence when managing complex, interoperable systems.
FACE Standard Conformance
Developing software that meets the FACE™ Technical Standard requires more than model creation. It demands built-in validation and seamless standards compliance. UDDL Modeler provides an integrated environment for developing FACE™ Edition 2.1.x and 3.x UoP Supplied Models (USMs) and Domain-Specific Data Models (DSDMs), with built-in conformance testing and model conversion capabilities. The result is a more efficient path to compliance, simplified migration between FACE editions, and greater confidence in system interoperability.

Generate Digital Artifacts
UDDL Modeler transforms digital models into the engineering artifacts and documentation needed throughout the development lifecycle. From Interface Control Documents (ICDs) to FACE™ artifacts and model-to-document exports, it automates the creation of critical deliverables while improving consistency, reducing manual effort, and streamlining collaboration across engineering teams.
Key capabilities include:
- Automatic generation of Interface Control Documents (ICDs)
- Model-to-document transformation with exports to Microsoft Office, OpenOffice, iWork, and PDF
- Import and export of FACE Edition 2.1.x and 3.x models
- Export of FACE 3.x IDL and TSS segment artifacts
- Generation of digital assurance artifacts supporting integration with safety-critical AFCE-178 FACE conformant platforms
