Technical Challenges in Open Metadata
summary
Open source ODPi Egeria aims to make metadata live and travel: peer to peer cohorts of OMAG servers exchange references and replicate hot data, connectors translate vendor formats, and governance services push/pull rules into pipelines. The project ships monthly, spans about two and a half years of work, models roughly 500 metadata types, supports multi-tenant cloud and edge, and includes a repository explorer UI and audit headers to preserve provenance.
