Reference

Prior to a data import any reference related to the data has to be defined in the reference table. Only references of real published articles should be defined. If a paper has a persistent identifier it must be given in the URI-field; if no identifier is defined, the link to the paper in pdf-format should be given instead. During the data import, the relation between a data set and its reference is made. To add a new reference in 4D, click on Reference, click new and fill out the fields as defined below:


 * Author(s): Names must already be defined in the staff table and will be added by multiple choice selection; authors are also recognized by staff IDs.
 * Year: 1998, for papers 'submitted' or 'in press' add the year of submission in the corresponding field.
 * Title: full title without abbreviations.
 * Source: full text, journals not abbreviated - examples:
 * Journals - Journal of Geophysical Research
 * Periodicals - Reports on Polar an Marine Research, Alfred Wegener Institute for Polar and Marine Research, Bremerhaven (give title, institute and home location)
 * Books - In: Bleil, U & Thiede, J (eds.), Geological History of the Polar Oceans, NATO ASI Series, Kluwer Academic Publishers, London
 * Volume: 53(2), set to 'submitted' or 'in press' if not yet published
 * Pages: 34-67 or 123 pp for complete books/thesis etc.
 * Label/Publication No.: proprietary publication number, e.g. AWI publ No 1234 or PKDB56789
 * Abstract: no use, leave free
 * Comment: no use, leave free
 * Keywords: select from thesaurus
 * URI: can be a URL, DOI, URN, SRef etc. or any other persistent identifier (add the 'protocol' to the URI with ':', e.g.
 * (add a DOI to a reference when ever available)
 * http://www2.awi-bremerhaven.de/Publications/Gro1987a.pdf
 * http://hs.pangaea.de/Projects/CRP/Henrys_et_al_2001.pdf (pdf-files should be stored on hs.pangaea.de/...)
 * http://www2.awi-bremerhaven.de/Publications/Gro1987a.pdf
 * http://hs.pangaea.de/Projects/CRP/Henrys_et_al_2001.pdf (pdf-files should be stored on hs.pangaea.de/...)

If using copy/paste to enter new references, avoid to add carriage returns or needless spaces into the fields!

A list of several references can be imported as ASCII-file with tab-delimited columns in the format and header as defined in the import form for references by using Menue File/Import, choose References. Author in the import list will be recognized if:
 * name and first name are identical, notification if several similar names
 * name and initials are identical, notification if several similar
 * name identical and initial identical with initial of first name (first letters of several first names are added for comparison)
 * name identical and 1. initial identical with initial of 1. first name (only if no other similar names are archived, e.g. Shackelton, N is recognized because Shackelton, Nicholas J  is the only record with name Shackelton in the staff list.

One to many references can be related to a data set. The references are selected during the import process while the order of references is set in the multiple choice window.

Data should be submitted and imported before a paper is in press. After import and proof read of the data, the author is provided with a DOI for data citation/identification to be used in the publication. The paper should not just refer to the Pangaea domain, but give the link precisely pointing to the relevant data.

Examples:
 * as a link to one specific data set or
 * as a link to a number of data sets grouped by a parent set or
 * http://www.pangaea.de/PangaVista?query=@Ref896 (896 is the PANGAEA internal reference ID) to show many data sets related to a publication without a parent definition. This link may be used if many data sets (some thousand) are related to one reference.

For refering to his data, the author may use a text like Supplementary data are published through the information system PANGAEA at
