Parent set

A parent set (parent) is a technical aggregation of two or more data sets.

If several data sets should be combined for a certain reason, e.g. to be made citable through a single citation, those Child sets are aggregated in a parent set. This is just a technical process as a prerequisite to give several data sets ONE citation and DOI. The DOI of the childs remain as a technical DOI, the DOI of the parent set may become a citation DOI as part of the official data publication.

On the web a parent set is presented with its list of childs, also providing the opportunity to download all childs in one zip-archive.

  • A parent set can not contain data sets with static URL.
  • Child sets can not belong to more than one parent set.
  • The definition of a parent is NOT required if just one data set belongs to the publication/data citation.
  • For an easier parent definition, the citation of the supplements reference should be related to each child set. When the parent is defined, in the child sets the reference will disappear under Reference(s): and instead will appear in Citation: as In Supplement to: ... (Example: doi:10.1594/PANGAEA.733935 )
  • The number of childs grouped in a parent is nearly unlimited. The following example includes 333 childs, has a total size of 8 MB and can be downloaded in one zip-archive. (Example: doi:10.1594/PANGAEA.715004 )
  • To formulate a query to find all childs of a parent, ask for parent:datasetID, e.g.

Child set

A child set (child) is a data set which belongs to a group of data sets. The group is bound into parent set. The child-parent grouping is used to get one DOI for several data sets belonging to a publication supplement.


Case 1

The supplement to a publication consists of more than one set; in this case all data sets related to the reference of the publication are grouped in a parent set. The parent set is also related to the reference and has the status supplementary data

Case 2

Case 2: A number of data sets are defined by the PI as a citable entity (e.g. could be all meteorological observations of one expedition). The data sets are grouped into a parent, an extended abstract is added, the parent proofread by the authors. After completion the parent is published by setting the status published.
