This site demonstrates Zepheira's approach to modular, layered vocabulary management that support our open source transformation tools and Linked Data training product offerings. These vocabularies are not intended to replace or compete with other Linked Data namespaces. These vocabularies serve as a basis for further scoping by BIBFRAME profiles. Our hope is by sharing this approach, others may consider similar practices for effective vocabulary management and distributed governance, and to demonstrate the flexibility of BIBFRAME. This work is ongoing and actively being shaped by participants of Zepheira's Practical Practitioner series.
