MInAS ancient DNA MIxS extension

Specifications of the Ancient DNA extension of the Minimum Information about any Ancient Sequence (MInAS) standard project, generated using LinkML (https://linkml.io/linkml/). This file is released by the MInAS project for use by anyone handling ancient DNA data or information about biological sequences. This file is also used as an authoritative 'source of truth' to generate downstream artifacts of the extension, available here: https://github.com/MIxS-MInAS/extension-ancient/blob/main/src/mixs/schema/ancient.yml.

This reference documentation site is an automated rendering of the specifications of the mixs-minas schema, generated using LinkML (https://linkml.io/linkml/)

This page only includes MInAS metadata terms from the 'ancient' extension as well as the controlled vocabulary (enumerations) and categories (subsets) - it does not include the full standard.
