DSW is based on a model derived from a community discussion about the relationships among the main Darwin Core classes. DSW creates a new class to accommodate an important aspect of its model that is not currently part of Darwin Core: a class of Tokens, which are forms of evidence. DSW uses Web Ontology Language (OWL) to make assertions about the classes in its model and to define object properties that are used to link instances of those classes.

Description
Version 0.4 to 1.0 fixed reversed dsw:locates and dsw:locatedAt. Added labels. Changed comments and descriptions to conform to DC and DwC precedent. Added subClassOf relations to RO hasEvidence and isEvidenceFor. Specified preferred direction for inverse object property pairs., Changes from version 0.2.1 to version 0.3: removal of all functional and inverse function properties of object property terms, use of dwctype classes, deprecation of terms replaced by dwciri: terms, removal of references to TDWG Ontology., Changes from version 0.3 to 0.4 change DwC class namespace from dwctype: to dwc: to follow class proposal, removed references to TDWG TaxonConcept ontology; deprecated terms that now have equivalent terms in Darwin Core., Change from version 1.0 to 1.0.1 Add CC0 license., Version 0.4 to 1.0 fixed reversed dsw:locates and dsw:locatedAt.

A goal in the creation of DSW was to facilitate consistent markup of biodiversity data so that RDF graphs created by different providers could be easily merged. Accordingly, DSW provides a mechanism for testing whether its terms are being used in a manner consistent with its model. Two transitive object properties enable the creation of simple SPARQL queries that can be used to discover new information about linked resources whose metadata are generated by different providers.
