The Data Governance Initiative, DGI, framework is an extensible set of corefoundational governance services – enabling enterprises to effectively andefficiently meet their compliance requirements within Hadoop and allowsintegration with the whole enterprise data ecosystem.
This will provide true visibility in Hadoop by using both a prescriptiveand forensic model, along with technical and operational audit as well aslineage enriched by business taxonomical metadata. It also enables anymetadata consumer to work inter-operably without discrete interfaces toeach other -- the metadata store is common.The metadata veracity is maintained by leveraging Apache Ranger to preventnon-authorized access paths to data at runtime.Security is both role based (RBAC) and attribute based (ABAC).
