1. Introduction

Audience: This document is targeted toward those who wish to understand how the Darwin Core terms are related to the structure of the Access to Biological Collections Data [ABCD] schema.

Before becoming a TDWG standard, the Darwin Core was instantiated and deployed in many different application profiles, all of them based on XML schema. In this document the openly developed and widely used versions of the Darwin Core ([CLASSIC], [MANIS], [OBIS], [DRAFT14], [CURATORIAL], [GEOSPATIAL]) are each compared (mapped conceptually) to the Access to Biological Collections Data [ABCD] schema. Each historical version is mapped in a separate table and can be referenced quickly from the index in Mappings section. Each element in each Darwin Core versions is mapped to the one or more xpath designations of the equivalent element(s) in the most current version of ABCD.

3. Introduction

Audience: This document is targeted toward those who wish to understand how the standard Darwin Core terms are related to previously used Darwin Core schemas.

Before becoming a TDWG standard, the Darwin Core was instantiated and deployed in many different application profiles, all of them based on XML schema. The openly developed and widely used versions of the Darwin Core ([CLASSIC], [MANIS], [OBIS], [DRAFT14], [CURATORIAL], [GEOSPATIAL]), [PALEO]) are each compared (mapped conceptually) to the current recommended Darwin Core terms [TERMS] in this document. Each historical version is mapped in a separate table and can be referenced quickly from the Mappings section below.
