To this end, the open metadata standards and core implementation is being developed through the Egeria ODPi open source project (https://github.com/odpi/egeria). This provides the APIs, adapters and interchange formats to allow metadata repositories to connect into the ecosystem.The proposal is to use Apache Atlas as provides the open source reference implementation for a native open metadata repository.
