Abstract
Much of biodiversity information involves interactions among organisms. For Example, one species eats another, or lives together with another, or several specimens were collected together. The Darwin Core standard includes fields that allow such interactions to be represented, but does not provide vocabulary for any specific interactions.
Information models represent interactions like these as relationships, which can be thought of as one or more triples (source, property, target). The source and target are often represented by object identifiers. In a relational database, the identifiers are keys or foreign keys. For example (Pleopeltis polypodioides, livesOn, quercus virginia). That is, resurrection ferns have been found living on live oaks.
This presentation will detail the role of identifiers in representing relationships, give examples of existing vocabularies for relationship properties, and discuss ways that the TDWG community can move forward in creating and adopting these vocabularies and representing interaction information.
