Levels
Maturity Level 1¶
- Sources, data sets, and metadata are onboarded and expressed as formal ontologies
- Authoritative (upstream) data sources and (downstream) consumers are documented and verified by users, data, and technology
- The inventory of applications is defined and selected for graph applications
- Requirements and dependencies for each outbound data flow are documented and verified (implementation in the graph is not a requirement)
- Business glossaries for in-scope use cases are defined and verified in the graph (including a list of data sources and datasets)
- Policy implemented mandating inventory maintenance and only authorizing the use of data that has been logged into the inventory
Maturity Level 2¶
- Use case tree(s) (UCTs) is/are defined, standardized, and implemented
- All upstream data sources are linked to the authorized systems of record (SORs) and distribution points
- Policy mandating the use of SORs and documentation of data flow is implemented
- Entitlements have been defined in the graph (governing access to sources of data in the inventory)
- Classifications (i.e. criticality, security, privacy) are aligned with the use case tree and captured in the knowledge graph
- Governance requirements (i.e. use cases, accountability, data sources, data flows, service level agreements (SLAs)) are modeled and registered into the knowledge graph
Maturity Level 3¶
- Data inventory is centralized in the graph and linked to governance for defined use cases
- Ontologies and data models (including change history and transformations) are registered in the knowledge graph
- Entitlements are calculated within the inventory and enforced at the datapoint level
- Data Quality is automatically calculated (fine-grained with dynamic value resolution) within the inventory for each use case
- Data retention rules are registered in the graph and automatically enforced
- Full audit trail for all upstream and downstream data usage is registered in the graph
- Data elements, calculation methods, and critical data elements (CDEs) are linked to individual regulatory requirements
Maturity Level 4¶
- Connected inventory has been extended to include real-time (transactional) data
- Inventory is extended to external suppliers and third parties along the supply chain
- The inventory is fully integrated with machine learning (ML) to optimize data flow
- The “value of data” is calculated and classified within the organizational inventory
Maturity Level 5¶
No further requirements.
