41. Taxonomic database challenge: Standardizing organisms and communities The problem: Integration of data potentially representing different times, places, investigators and taxonomic standards. The traditional solution: A standard list of organisms / communities.

42. Standardized taxon lists fail to allow dataset integration The reasons include: Taxonomic concepts are not defined (just lists),Taxonomic concepts are not defined (just lists), Relationships among concepts are not definedRelationships among concepts are not defined The user cannot reconstruct the database as viewed at an arbitrary time in the past,The user cannot reconstruct the database as viewed at an arbitrary time in the past, Multiple party perspectives on taxonomic concepts and names cannot be supported or reconciled.Multiple party perspectives on taxonomic concepts and names cannot be supported or reconciled.
