Sample interview questions: Describe your understanding of metadata crosswalks and the challenges associated with maintaining mappings.
Sample answer:
-
Metadata crosswalks:
*Mappings between different metadata schemas or standards; enables data sharing and integration; allows users to interpret and use data consistently across systems.
-
Challenges in maintaining mappings:
Structural differences: Different metadata schemas may have different structures, making it difficult to map elements directly.
Semantic differences: Metadata elements may have different meanings or interpretations in different schemas, leading to ambiguous or incorrect mappings.
Versioning: Metadata schemas may be updated over time, requiring the crosswalks to be revised accordingly to ensure data integrity.
Data quality: Inconsistent or incomplete data in source systems can lead to errors in the crosswalks and impact the accuracy of data integration.
Scalability: Maintaining crosswalks can become challenging as the number of metadata schemas and the volume of data involved increase, requiring effici… Read full answer
