@DC:bibliographicCitation | Optional: Full, plain text bibliographiccitation for the current file. | Example: Mueller, R.D. and Seton, M. and Roest, W. (2008): Global. Geochem., Geophys., Geosys. xx: . |
@DC:description | Mandatory: Description of data set contained in this file. Multiline comment wrapped in triple quotation marks “”“ (like in Python) are allowed, as are multiple ocurrences of the attribute to mimick the same effect as for multiline value. | Example: A sample rotation file in the new GPlates rotation file format v1.1 |
@DC:contributor | Mandatory: Author data attribute for every contributor to this file. Data needs to be split into at least 5 different fields separated by vertical bars (|): (1) ID – Unique ID for contributor (e.g. “FOOB” for “Foo Bar”), this maps to the @AU tag in rotation sequence comments; Real Name – of contributor (Odd Name); Email – Email of contributor; URL– Website of contributor; Institute, Postal address, other contact details for contributor. Fields can be left blank. | |
Supplementary header information
@REVISIONHIST | Optional. Parent attribute for data which is under a revisioning system. User can generate child attributes by separating them with a colon (:) from the parent tag. | Example: |
@BIBINFO | Optional. Parent attribute for bibliographic reference data related to this rotation file | |
@BIBINFO:bibliographyfile | Optional. URI for location of bibliographic reference data in BibTeX format. | Example: rotationfile_1-0.bib |
@BIBINFO:doibase | Mandatory. URL for resolving DOIs used in thebibliographic data. | Default: https://doi.org/ |
@GPML | Parent attribute for GPGIM-derived attributes | |
@GPML:namespace | Mandatory. URI for the locationof the GPGIM Schema document. | Currently: http://www.earthbyte.org/Resources/GPGIM/stable/ |
@GEOTIMESCALE | Mandatory. Bibliographic data for individual time scales used. Data is split into at least 3 fields, separated by vertical bars (|) and can extend over multiple lines using the triple quotation marks. These are 1) ID – unique ID of timescale to be used in the @GTS tag for the individual rotation sequences. 2) DOI/URL/ISSN – Unique identifier for publication the timescale is based upon, prefixing the actual values (like doi:12.12312/991823); 3) Plain text full bibliographic reference for timescale or comments. |
Rotation sequence metadata
The rotation sequence metadata attribute aliases apply to both, the MPRS header segment as well as individual lines.
| Attribute name | Definition | Example | |
|---|---|---|---|
@REF | Optional | Unique citation key of bibliographic data used forthis rotation. Maps to entries specified in @BIBINFO:bibfile value. | |
@DOI | Alias Optional. Digitial object identifier for bibliographicdata used for this rotation. Maps to entries specified in @BIBINFO:doibase value for complete a valid URL. | ||
@AU | Alias Optional. Author of rotation sequence data, maps tofirst field of @DC:contributor, which is the unique contributor ID. | Example: @AU”ODDNAME“. | |
@CHRONID | Alias for Magnetic anomaly chrons as specified in GPGIM. | ||
GTS | Alias optional | GEOTIMESCALE:id |
