specimen.xsd SamplingFeatures are feature types that are used primarily for making observations: SamplingFeature, and collections are described in samplingBase.xsd Specimen and LocatedSpecimen are described in this schema document Sampling is an OGC Standard.

An object on which measurements may be made, often ex-situ. Note that if this specimen is a "processed" version of another (e.g. by grinding, sieving, etc) then the predecessor (if known) may be recorded as a relatedSamplingFeature Material type, usually taken from a controlled vocabulary Specialised domains may choose to fix the vocabulary to be used Its value may be relatively generic (rock, pulp) or may reflect a detailed classification (calcrete, adamellite, biotite-schist). In the latter case it is wise to use the codeSpace attribute to provide a link to the classification scheme/vocabulary used. Storage location of specimen if it still exists. If destroyed in analysis, then either omit or use xlink:href to point to a suitable URN, e.g. urn:cgi:def:nil:destroyed The size of the specimen: mass, length, volume, etc Xlink attributes added to enable rich annotation, e.g. size-type Method used when retrieving specimen from host sampledFeature Time and date when the specimen was initially retrieved One or more procedures may have been applied to a specimen. May contain collection, sampling and preparation procedures Sampling location may be provided directly if not available through its association with either the sampledFeature or a relatedSamplingFeature
