This document discusses three problems related to linking specimens to evidence in biological databases: 1) linking specimens to DNA barcodes, sequences, and literature citations in databases like GBIF, 2) the relationship between physical biological collections and institutions and their digital representations in databases like GBIF, and 3) making Wikipedia pages on species more structured and machine-readable similar to Bouchout declarations. Suggestions are made to map specimen identifiers to other databases, provide live updates of digitization efforts, and allow for user-editable structured data.
