Metadata


Next to the actual data file, each Metapsy database repository also contains a folder in which metadata is stored. Metadata items may vary between repositories, but a core selection of files is always included. We focus on these metadata items here.

An example of a metadata repository folder can be found here.


Metadata Items


The following standard metadata items are always included in the metadata repository folder:

  • 📄 authors.json: A .json file containing the authors or owners of the the database, as well as their ORCID research ID.
  • 📄 last_search.txt: A .txt file containing the date of the last search update, in the YYYY-MM-DD format.
  • 📄 number_studies.txt: A .txt file containing the number of studies included in the current version of the database.
  • 📄 search_string.txt: A .txt file showing the employed search string(s).
  • 📄 shorthand.txt: A .txt file with the metapsyData shorthand of the database.
  • 📄 variable_description.json: A .json file; containing a JSON object (key-value pairs). The key represents the variable name, while the value component includes a description or explanation provided for the database variable (e.g. information on the meaning of factor levels).
