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.

Example CSPP-compliant RDF-document

The RDF in this example is for the CETAF-ID http://herbarium.bgbm.org/object/B100068798 and it can contain the following:

Note that …

  • it first describes the very RDF resource (got to by redirect) and
  • it relates to the requested CETAF-ID by dc:subject and the rdf:Description that follows elaborates the CSPP-details and more related properties to this species data (images, other same data objects etc.)
