Supplement

A data supplement consists of primary data related to a publication. The material is provided as extra file(s). Supplementary data can be archived in the repository of the publisher/journal or in Pangaea. The benefits for a storage in Pangaea are
 * Open Access,
 * own identity with DOI,
 * distribution on the Internet via web services through portals, search engines and library catalogs with an increase of the publications impact,
 * machine readability and thus the option to easily compile data from various publications in one new product.

Mondatory for the definition of a supplement in Pangaea is the complete import of all related primary data and its proofread and acceptance by the author(s). Steps for publishing a supplement are:
 * 1) Import all data; each data set has to be related to the reference.
 * 2) If the supplement consists of several datasets, define a parent by selecting all sets and press . Add title and export filename.
 * 3) Inform the author about data availability by sending the DOI as link and ask for proof-read.
 * 4) Make corrections until the authors final OK.
 * 5) If the supplement consists of one dataset, set its status to supplementary data.
 * 6) If the supplement consists of several datasets, set the status of the parent to supplementary data. The authors of childs and parent are automatically listed as given in the reference.
 * 7) Check the valid appearance of the supplement on the Internet.

If the child>parent grouping is used, the reference related to the data sets will disappear in all childs and only apprear in the parent as supplement to:.

Why should supplements not be archived in the repository of the publisher:
 * Publisher, journal, editors and reviewers do not care about the format of the data
 * Supplements of articles in commercial journals are not in Open Access
 * Data did not underwet a technical review or consistency check
 * Data are not machine readable -> no added value

Examples

 * One data set as supplement: which appears as a link on the papers splash page in ScienceDirect, see
 * Several data sets grouped to a parent set as supplement to a chapter in a book
