- Abstract
- The Chronometric Age Vocabulary is a standard for transmitting information about chronometric ages - the processes and results of an assay or other analysis used to determine the age of a MaterialSample. This document lists all terms in namespaces currently used in the vocabulary.

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.

Term version IRI |

Label |
Chronometric Age |
Definition |
An approximation of a temporal position (in the sense conveyed by https://www.w3.org/TR/owl-time/#time:TemporalPosition) that is supported via evidence. |
Notes |
The age of a specimen and how this age is known, whether by a dating assay, a relative association with dated material, or legacy collections information. |
Examples |
`An age range associated with a specimen derived from an AMS dating assay applied to an oyster shell in the same stratum`; `An age range associated with a specimen derived from a ceramics analysis based on other materials found in the same stratum`; `A maximum age associated with a specimen derived from K-Ar dating applied to a proximal volcanic tuff found stratigraphically below the specimen`; `An age range of a specimen based on its biostratigraphic context`; `An age of a specimen based on what is reported in legacy collections data`. |

Label |
Material Dated Relationship |
Definition |
The relationship of the materialDated to the subject of the ChronometricAge record, from which the ChronometricAge of the subject is inferred. |
Notes |
Recommended best practice is to use a controlled vocabulary. |
Examples |
`sameAs` (cases where the subject material was completely destructively subsampled to get the ChronometricAge), `subsampleOf` (cases where part of the original specimen was extracted as the material used to determine the ChronometricAge), `inContextWith` (cases where the ChronometricAge is inferred from materialDated, such as sediments or cultural objects, in related temporal context),`stratigraphicallyCorrelatedWith` (cases where the ChronometricAge is inferred from materialDated in a stratigraphically correlated context) |

Label |
Verbatim Chronometric Age |
Definition |
The verbatim age for a specimen, whether reported by a dating assay, associated references, or legacy information. |
Notes |
For example, this could be the radiocarbon age as given in an AMS dating report. This could also be simply what is reported as the age of a specimen in legacy collections data. |
Examples |
`27 BC to 14 AD`, `stratigraphically pre-1104` |
