Plant-Pollinator Interactions vocabulary quick reference guide

This document is intended to be an easy-to-read reference of the currently (as of 2022-01-06) recommended terms maintained as part of the Darwin Core standard and is maintained by the Brazilian Network on Plant-Pollinator Interactions.

This page is not part of the standard, but combines the normative term names and definitions with the non-normative comments and examples that are meant to help people to use the terms consistently. Capitalized terms, such as Occurrence, are Darwin Core classes, which are special category terms used to group sets of terms for convenience. Comprehensive metadata for current and obsolete terms in human readable form are found in the document List of PPI terms.

Additional files with just the current term names and a file with the full term history can be found in the PPI repository.
