1 Introduction
This document contains all versions of terms in the Chronometric Age vocabulary (http://rs.tdwg.org/version/chrono/2021-02-21). The vocabulary uses the namespace abbreviation chrono:
. Earlier term versions using the zooarchnet:
namespace are deprecated and should no longer be used. These deprecated terms can be found at http://rs.tdwg.org/chrono/zooarchnet/.
For a simplified list that contains only the currently recommended terms, see the Chronometric Age Quick Reference Guide (https://tdwg.github.io/chrono/terms/).
1.1 Status of the content of this document
In Section 4, the values of the Term IRI
, and Definition
are normative. The values of Term Name
are non-normative, although one can expect that the namespace abbreviation prefix is one commonly used for the term namespace. Label
and the values of all other properties (such as Notes
and Examples
) are non-normative.
1.2 RFC 2119 key words
The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in RFC 2119.
2 Use of Terms
The terms in this standard are meant to provide stable definitions that can be used in a variety of contexts, but were envisioned principally to function together as an extension to Darwin Core, where each core record may be annotated by one or more chronometric ages.
