Lecture Notes: Metadata and Documentation in Research Data Management

Introduction to Metadata

  • Definition: Metadata is data that describes other data.
  • Importance: Enables data to be found and reused.
  • Difference from Documentation: Metadata records essential information in a highly structured way for machine readability.

Functions of Metadata

  • Facilitates searching and finding data.
  • Assesses data usefulness without downloading.
  • Indicates data access and reuse conditions.
  • Essential for making data FAIR (Findable, Accessible, Interoperable, Reusable).

Types of Metadata

  1. Descriptive Metadata:
    • Elements: Title, Author, Keywords.
    • Function: Helps discover data.
  2. Technical Metadata:
    • Information: File access, type, size.
  3. Administrative Metadata:
    • Elements: Intellectual property rights, license.
  4. Structural Metadata:
    • Function: Shows relationships with other online resources.

Creation and Storage of Metadata

  • Automatic Generation: By instruments like microscopes, telescopes, digital cameras.
  • Manual Creation: Through notes, forms, lab notebooks.
  • Storage:
    • Embedded within files.
    • As separate files (Readme, Spreadsheet).
  • Examples: SPSS files, file headers, geospatial metadata.

Metadata in Data Repositories

  • Role of Repositories: Help increase data FAIRness.
  • Metadata Standards:
    • Definition: Widely accepted set of elements for describing resources.
    • Examples: Dublin Core, DataCite, Ecological Metadata Language, DDI.
    • Importance: Facilitates data exchange and interoperability.

Best Practices

  • Familiarize with repository-required metadata.
  • Document metadata during project to avoid reliance on memory.

Conclusion

  • Metadata enhances data findability and usability.
  • Data repositories are essential for managing machine-readable metadata.
