Parent

A parent set is an aggregation of two or more data sets.

If several data sets should 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 make several data sets easily citable. The DOI of the childs remain as a technical DOI, the DOI of the parent set will become a citation DOI as part of the official data citation.

On the web a parent set is presented with its list of included 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.

Case 1: Supplementary data to a publication are citable and the data consist 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
 * Example of a parent set as Supplement to: including 9 childs:

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 to a parent by the Pangaea editor, an abstract is added and the parent is made citable after proof read.
 * Example of a parent set including 10 unpublished child sets:

A parent set is technicaly defined by the editor in the following steps:
 * select the childs which should be grouped to a parent (e.g. by a retrieval on the reference)
 * select all entries in the list
 * click on 
 * some fields will be filled with entries depending on the related sets
 * modify metadata as appropriate, e.g. add technical comments related to all data
 * add a short but significant title describing the data content
 * add an export file name (for supplements: author-et-al_year)
 * add abstract
 * 
 * Parent will be available after short time (after marshalling), list of childs on it will be available after max. 35 minutes (at XX:15 and XX:45), when PangaVista is updated.
 * always check validity in web view
 * ask author(s) for review
