In metadata, a data steward's role is assigned to a person that is responsible for maintaining a data element in a metadata registry.
Data stewardship roles are common when organizations are attempting to exchange data precisely and consistently between computer systems and reuse data-related resources. Master Data Management often makes references to the need for data stewardship for its implementation to succeed.
Data Steward Responsibilities
A data steward ensures that each assigned data element:
- Has clear and unambiguous data element definition.
- Does not conflict with other data elements in the metadata registry (removes duplicates, overlap etc.)
- Has clear enumerated value definitions if it is of type Code.
- Is still being used (remove unused data elements)
- Is being used consistently in various computer systems
- Has adequate documentation on appropriate usage and notes
- Documents the origin and sources of authority on each metadata element
Benefits of Data Stewardship
- Consistent use of data management resource
- Easy mapping of data between computer systems and exchange documents
- Lower costs associated with migration to Service Oriented Architecture (SOA)
Assignment of each data element to a person sometimes seems like an unimportant process. But many groups have found that people are more likely to trust and use a system where there is a person they can call with question on each data element.
An example of data stewardship is the EPA metadata registry [1]. Note that each data element has a "POC" (point of contact).
