Retrospective on 15 Years of Data Modeling

This white paper chronicles a 15-year journey of developing the FACE® Data Architecture, detailing key milestones, technical challenges, and transformative insights. It begins by outlining the initial vague definitions and challenges faced, such as unclear terminology and the absence of formal tooling. The authors describe how these challenges were addressed through iterative testing and creative scripting. The paper highlights significant developments, including the introduction of the FACE Conformance Test Suite, which allowed for third-party testing of data models. It explains how the FACE Data Architecture has improved interoperability by providing a consistent representation of data semantics, enabling model interchange without proprietary extensions. The authors reflect on the evolution of the standards and the ongoing efforts to enhance the data architecture, emphasizing the importance of clear documentation and automated validation processes. This retrospective aims to provide context and insights into the complexities of data modeling over the past fifteen years.
