CETAF Specimen Preview Profile (CSPP)

The CSPP is a minimal set of agreed (RDF) collection metadata elements implemented consistently across CETAF organisations (see minutes of the Geneva meeting of the ISTC stable identifier initiative). The purpose of CSPP is to provide a stable resource enabling preview functions in specimen portals. The CSPP is not meant to be comprehensive, which means that Linked Open (collection) Data implementations of CETAF institutions will usually provide much richer metadata with additional RDF-elements.

CSPP Elements

CSPP element	Mandatory	RDF resource URI	Notes
title	yes	http://purl.org/dc/terms/title	Mandatory. Collection may decide themselves on the content of the title element. This could usually be a scientific name (with or without authorship), but it could also contain additional information on collectors and projects for example.
kindOfMaterial	no	http://purl.org/dc/terms/type	The nature of the specimen. Example: herbarium sheet, fossil, conserved in alcohol
scientificNameCurrent	no	http://rs.tdwg.org/dwc/terms/scientificName	The latest full scientific name, with authorship and date information if known.
family	no	http://rs.tdwg.org/dwc/terms/family	The full scientific name of the family in which the taxon is classified.
scientifcNameOriginal	no	http://rs.tdwg.org/dwc/terms/previousIdentifications	The original name appearing on the specimen.
collectorNumber	no	http://rs.tdwg.org/dwc/terms/fieldNumber	An identifier given to the Occurrence at the time it was recorded. Often serves as a link between field notes and an Occurrence record, such as a specimen collector’s number.
collectorName	no	http://rs.tdwg.org/dwc/terms/recordedBy	A list (concatenated and separated) of names of people, groups, or organizations responsible for recording the original Occurrence. The primary collector or observer, especially one who applies a personal identifier (recordNumber), should be listed first.
webscaledImageLink	no	http://rs.tdwg.org/dwc/terms/associatedMedia	Link to “nice” webscaled image.
latitude	no	http://rs.tdwg.org/dwc/terms/decimalLatitude	The geographic latitude (WGS84, in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are north of the Equator, negative values are south of it. Legal values lie between -90 and 90, inclusive.
longitude	no	http://rs.tdwg.org/dwc/terms/decimalLongitude	The geographic longitude (WGS84, in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are east of the Greenwich Meridian, negative values are west of it. Legal values lie between -180 and 180, inclusive.
isoCountry	no	http://rs.tdwg.org/dwc/terms/countryCode	The standard (ISO 3166-1 alpha-2) code for the country in which the specimen has been collected. Recommended best practice is to use ISO 3166-1-alpha-2 country codes.
collectionDate	no	http://purl.org/dc/terms/created	(Iso) date of the gathering event.
sourceLink	no	http://purl.org/dc/terms/publisher	URI to a web page with information about the institution/collection/owner responsible for publishing the specimen.
