Interoperability of Data Created using Extensible Data Standards Research - in - Progress

As an important data quality dimension, semantic interoperability of data can potentially be improved using data standards. Certain data standards are extensible, allowing users to introduce custom data elements. How interoperable is data created using an extensible data standard? How does extensibility of a data standard affect interoperability of data created using the standard? How does a standard evolve and what is its impact on interoperability? This research address these questions by empirically measuring semantic interoperability of real world data created using a large extensible data standard. It also uses case studies to develop an understanding of how users extend data standards. Preliminary results of the impact of standard evolution on data’s interoperability are also discussed.
