Data for Research

Data Documentation

The "Describe" stage of the Data Life Cycle is about documenting the data collected with metadata. Metadata describes data points and data within a set and is helpful for data sharing and reusing.

READme Files

When describing your own research data, a best practice is to create a READme file that fully describes your data.  A READme file should contain the following sections:

  • General Information
  • Data & File Overview
  • Data Description or Data Dictionary
  • Methodological Information

In the General Information section you should include at least the following information:

  • Title of the Dataset
  • Author information
  • Limits or restrictions on the data resuse
  • Funding information, if applicable

In the Data & File Overview section, you should explain the file structure of your data, listing all of the files in your dataset. Additionally, you should explain the file naming convention used for your files. 

The Data Description or Data Dictionary defines the variables, abbreviations, and null values. For more information on a making Data Dictionary see the box below.

Finally, in the Methodological Information section, include information about:

  • How and when the data was collected and/or created
  • Software used to generate the data and if applicable, required to access it
  • Equipment used to generate the data, if applicable

 Below find a template for a generic READme template you can use to describe your data. Please note that if you are depositing to a specific repository or have additional information required by your specialty, you may need a more specialized READme file template.

Metadata Standards

Metadata standards are agreed upon formats on how metadata should be developed and used in order to help with readability and understanding of the data. Which standard is used is dependent on the field of your research, the repository you are using, how accessible you think the standard would be for others who will use your data, etc. 

If you need help identifying the right Metadata standard for your research, it may be helpful to meet with a librarian.
