Metadata (Data About Your Data!)
Metadata is the information that describes, organizes, and provides context for your research materials. It acts as "data about your data," ensuring that your materials are discoverable, understandable, and usable for current and future audiences. Proper metadata is essential for maintaining accessibility, long-term preservation, and ethical transparency.
1. What is Metadata?
Metadata provides structured details about your materials, answering key questions:
- What is this? Title, description, and subject matter.
- Who created it? Authors, interviewers, participants.
- When and where? Dates, locations, and settings.
- How was it made? File formats, technical specifications, and recording devices.
2. Types of Metadata
-
Descriptive Metadata:
- Helps users identify and understand the material.
- Includes:
- Titles: "Oral History Interview with Jane Doe"
- Subjects: "Women in STEM," "Rural Utah"
- Keywords: "engineering," "family life"
-
Administrative Metadata:
- Manages the material's lifecycle and access.
- Includes:
- File formats: WAV, MP4, PDF/A
- Rights and permissions: "Creative Commons BY-NC-SA 4.0"
- Custodianship: "Fife Folklore Archives, Utah State University"
-
Technical Metadata:
- Details technical aspects of the files.
- Includes:
- Audio sample rates: 48kHz, 24-bit
- File size: "2.4 GB"
- Device used: "Zoom H5 Recorder"
-
Structural Metadata:
- Organizes the relationship between items.
- Includes:
- Chapters or segments of an interview.
- Links between a transcript and its corresponding audio file.
3. Why Metadata Matters
-
Improves Discoverability:
- Helps researchers and the public locate your materials through keywords, titles, and subject headings.
- Makes your work searchable in institutional repositories, library catalogs, and online databases.
-
Ensures Usability:
- Provides context for users to understand your materials.
- Preserves essential details about file formats and technical specifications for future access.
-
Supports Ethical Transparency:
- Documents participant consent, usage rights, and data handling protocols.
- Clarifies how and why the material was created.
-
Facilitates Collaboration and Sharing:
- Standardized metadata enables compatibility across platforms and institutions.
4. How to Create Effective Metadata
-
Use Standards:
- Follow metadata schemas such as:
- Dublin Core (general use)
- MODS (Metadata Object Description Schema, used in libraries)
- PBCore (for audiovisual materials)
-
Be Consistent:
- Use a standardized naming schema for files and consistent terminology for metadata fields.
- Example: "2024-11-20_Smith_Interview.wav"
-
Include Essential Details:
- Example Metadata for an Interview:
- Title: Oral History Interview with Jane Doe
- Interviewer: John Smith
- Participant: Jane Doe
- Interview Date: November 20, 2024
- Location: Logan, Utah
- Keywords: Women in STEM, Rural Utah
- File Format: WAV, 48kHz
-
Document Changes:
- Record updates, edits, or redactions to transcripts or files.
- Example: "Redacted 11/22/2024 to remove sensitive details."
5. Tools for Metadata Creation
-
Spreadsheet Software (Excel, Google Sheets):
- Use to create simple metadata tables.
- Example Fields: Title, Date, Interviewer, File Type, Rights.
-
Metadata Editing Tools:
- OpenRefine: Clean and standardize metadata.
- Adobe Bridge: Add metadata to media files.
-
Integrated Platforms:
- Institutional repositories or collection management systems like CONTENTdm or Omeka often have built-in metadata fields.
Best Practices for Metadata
- Think Long-Term: Metadata should serve users now and in the future, so include enough detail for someone unfamiliar with the project.
- Prioritize Accuracy: Double-check names, dates, and technical specs.
- Align with Participant Consent: Ensure metadata reflects any restrictions or preferences set by participants.
- Collaborate with Experts: Work with archivists or metadata specialists to ensure your data meets professional standards.
