The universe of metadata standards is expansive, diverse, and continuously evolving. My project supported the creation of KAOS (Knowledge-Advancing Organization Systems), an online repository for metadata schemes and schemas of all forms, functions, and levels of complexity - including controlled vocabularies, thesauri, web ontologies, subject lists, classification schemes, indexing languages, descriptive frameworks, conceptual models, and more. After exploratory research into data ingest, storage, migration, transformation, analysis, and visualization, I designed, tested, and implemented a proof-of-concept infrastructure and workflow that lays the foundation for development to begin on a larger scale. When fully launched, the KAOS platform will use linked data to visually represent relationships among metadata standards and show changes in those standards over time. As a centralized access point to the wide world of metadata vocabularies, KAOS serves as a valuable resource for information professionals in any domain or industry.
