FAIR Data Principles

FINDABLE: Metadata and data should be easy to find for both humans and computers.

ACCESSIBLE: Once the user finds the required data, s/he needs to know how can they be accessed.

INTEROPERABLE: Data usually need to be integrated with other data. And data need to interoperate with applications or workflows for analysis, storage, and processing.

REUSABLE: Metadata and data should be well-described so they can be replicated and/or combined in different settings.

Metadata Overview

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.

This definition comes from the National Institute Standards Organization (NISO) publication Understanding Metadata

Metadata in Plain Language - USGS gives a good overview for creating metadata

 

Minimal metadata to keep with the data:

  • About the project:
    • Title, people, key dates, funders and grants
  • About the data:
    • Title, key dates, creator(s), subjects, rights included files, format(s), versions, checksums
    • Interpretive aids: codebooks, data dictionaries, algorighms, code

 

 

Standards

"The great thing about standards is that there are so many to choose from." -author unknown

Dublin Core - Defines fifteen basic metadata elements for resource discovery in a cross-disciplinary information environment, designed for interoperability. Learn more at about the Dublin Core Metadata Initiative

Disciplinary Metadata - from the Digital Curation Centre in the UK

Metadata Crosswalks

You may need to use a crosswalk to convert your metadata to a different standard. Examples include:

FGDC to a variety of schemas - from NOAA

CDWA to VRA 4.0 to MODS to EAD - from The Getty
