Audience: This document is an introduction to the Darwin Core - standard and is meant to provide the background, reasons, and basic - information about sharing (either as a publisher or user of) biodiversity - information. Further details on specific aspects of the standard and its use - can be found in the pages shown in the Table of Contents in the upper left of - every page or in the References section of this - page.
- -What is the Darwin Core?
- -The Darwin Core is body of standards. It includes a glossary of terms (in - other contexts these might be called properties, elements, fields, columns, - attributes, or concepts) intended to facilitate the sharing of information - about biological diversity by providing reference definitions, examples, and - commentaries. The Darwin Core is primarily based on taxa, their occurrence in - nature as documented by observations, specimens, samples, and related - information. Included are documents describing how these terms are managed, - how the set of terms can be extended for new purposes, and how the terms can - be used. The normative document for the terms [RDF-NORMATIVE] is written in the Resource - Description Framework (RDF) and is the definitive resource to understand the - term definitions and their relationships to each other. The Simple Darwin - Core [SIMPLEDWC] is a - specification for one particular way to use the terms - to share data about - taxa and their occurrences in a simply structured way - and is probably what - is meant if someone suggests to "format your data according to the Darwin - Core".
- -Motivation: The Darwin Core standard was originally conceived to - facilitate the discovery, retrieval, and integration of information about - modern biological specimens, their spatiotemporal occurrence, and their - supporting evidence housed in collections (physical or digital). The Darwin - Core today is broader in scope and more versatile. It is meant to provide a - stable standard reference for sharing information on biological diversity. As - a glossary of terms, the Darwin Core is meant to provide stable semantic - definitions with the goal of being maximally reusable in a variety of - contexts.
- -Rationale: The Darwin Core is based on the standards developed by - the Dublin Core Metadata Initiative [DCMI] and can be viewed as an extension of the - Dublin Core for biodiversity information. The purpose of these terms is to - facilitate data sharing by providing a well-defined standard core vocabulary - in a flexible framework to minimize the barriers to adoption and to maximize - reusability. The terms described in this standard are a part of a larger set - of vocabularies and technical specifications under development [TDWG-DEV] and maintained by - Biodiversity Information Standards (TDWG) [TDWG-STANDARDS].
- -Guiding principles: Each term has a definition and commentaries - that are meant to promote the consistent use of the terms across applications - and disciplines. Evolving commentaries that discuss, refine, expand, or - translate the definitions and examples are referred to through links in the - Comments attribute of each term. This means of documentation allows - the standard to adapt to new purposes without disrupting existing - applications. There is meant to be a clear separation between the terms - defined in this standard and the applications that make use of them. For - example, though the data types and constraints are not provided in the term - definitions, recommendations are made about how to restrict the values where - appropriate.
- -Content: The standard consists of a vocabulary of terms - (properties, elements, fields, concepts) [TERMS], the policy governing the maintenance of these - terms [NAMESPACEPOLICY], the - decisions that resulted in changes to terms [DECISIONS], the complete history of - terms including detailed attributes [HISTORY], a Generic Darwin Core XML - schema [TERMSXMLSCHEMA] from which - other schemas can be constructed, a Simple Darwin Core XML schema - [SIMPLEXMLSCHEMA] as a complete - schema ready for use, a schema to allow Darwin Core data transfer in text - files [TEXTSCHEMA], and associated - reference schemas for the construction of more structured content. These - pages also describe mappings between the current standard and pre-standard - historical versions [VERSIONS], including mappings - [DWCTOABCD] to concepts in - the Access to Biological Collections Data standard [ABCD].
- -Extension: Though the Darwin Core is insufficient for the needs of - all biological disciplines, it can be adapted to serve new purposes. Darwin - Core can be extended by adding new terms to share additional information. To - do so you should be familiar with the recommendations and procedures defined - in the Darwin Core Namespace Policy [NAMESPACEPOLICY]. Basically, before - proposing a new term, consider the existing terms in this and other - compatible standards to determine if the new concept can be accommodated by a - simple revision of the description and comments for an existing term, without - losing the existing meaning of that term.
- -Participation: To receive notification of activity or participate - in discussions about Darwin Core, join the tdwg-content mailing list - [TDWG-CONTENT] and - watch the Darwin Core Project [DWC-PROJECT]. For discussion or commentary - on the definition of recommended terms, consult the link inside the - Comment section in the listing for the term in the Quick Reference - Guide [TERMS] or search for the relevant - content in the auxiliaryDarwin Core Documentation [DWC-WIKI].
- -To make a formal request for a change to or addition of a term to the - Darwin Core, read and follow the recommendations in the Darwin Core - Namespace Policy [NAMESPACEPOLICY]. For those who wish to - construct and submit as a standard any application profile, such as an XML - schema, that extends the capabilities of the Darwin Core, adding new terms to - the Darwin Core vocabulary that don't already exist in a compatible - vocabulary will be a prerequisite. Consult the appropriate guideline, such as - the XML Guide [XMLGUIDE], - for information about the construction of a new application profile. The - rules of submission of proposed standards can be found in the Biodiversity - Information Standards (TDWG) process document [PROCESS].
