Parent

A 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: )

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
 * Example of a parent set as Supplement 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 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 & citable.
 * Example of a parent set including 10 unpublished child sets:

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. To formulate a query to find all childs of a parent, ask for parent:datasetID, e.g.
 * http://www.pangaea.de/search?q=parent:715004

A parent set is technicaly aggregated by the curator in the following steps:
 * select the childs which should be grouped to a parent; if the childs are all related to one reference, the selection can be done by drag'n'drop from the citation in the reference table on to the data set table,
 * 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 content of the parent,
 * add an export file name (for supplements: author-etal_year),
 * add abstract for supplements (copy from the paper) or data publications (extended abstract),
 * ,
 * parent is available in a minute; childs will be listed after ~35 minutes, when PangaVista is updated (at hh:15 and hh:45),
 * always check validity in web view,
 * always ask author(s) for review.
