Module 3: Metadata
What is Metadata?
Metadata is structured information that
describes, explains, locates, or otherwise
makes it easier to retrieve, use, or manage
an information resource. Metadata is often
called data about data or information about
information” (NISO, Understanding Metadata
2004;1).
Module 3: Metadata
You Must Have Metadata to:
• Find data from other researchers to
support your research;
• use the data that you do find;
• help other professionals to find and use
data from your research;
• use your own data in the future when you
may have forgotten details of the research.

Technical Standards
ISO 8601 technical standard:
•
•
•
•
Year Only: YYYY (eg 1997)
Year and month: YYYY-MM (eg 1997-07)
Complete date: YYYY-MM-DD (eg 1997-07-16)
Media types can be problematic as well:
– The MIME media types helps you chose among the
following: Application, audio, example, image,
message, model, multipart, text, video

•
Consult a librarian!
Consistent data entry is important
Avoid extraneous punctuation
Avoid most abbreviations
Use templates and macros when possible
Extract pre-existing metadata
Keep a data dictionary
Always use an established metadata
standard
Module 3: Metadata
Activity
• Use the Dublin Core metadata elements to
create a metadata “record” for a data set
you are working with
• Use the Dryad Dublin Core record as a
guide.
