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.
The following standard metadata items are always included in the
metadata repository folder:
.jsonfile containing the authors or owners of the the database, as well as their ORCID research ID.
.txtfile containing the date of the last search update, in the
.txtfile containing the number of studies included in the current version of the database.
.txtfile showing the employed search string(s).
.txtfile with the
metapsyDatashorthand of the database.
.jsonfile; 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).
There is also one additional metadata item stored at the base of the repository:
license: A file that contains the license under which the data is shared. This is either the license text itself, or a persistent identifier to the license. By default, all datasets are assigned with a Open Data Commons Attribution License (ODC-By) v1.0 license, which allows anyone to share and adapt the data, as well as to create works from the it, provided that the original database is attributed.
