Define "in_subset"

[only1chunts]

The linkML attribute of "in-subset" is used to represent the GSC-MIXS "Sections". The section is defined as:

The grouping of a metadata term into a specific category. The current sections are;

• Investigation ; terms that relate to the project and linking it to other electronic resources.
• Nucleic acid sequence source ; terms that are about where and how the DNA sample was created.
• Sequencing ; terms that relate to how the DNA sample was processed for sequencing.
• Environment ; terms that relate to the environment from which the sample/DNA was obtained.

It should be noted that the sections are currently under review and there is a strong chance that the 4 sections listed above will change in v7, see issue #772 .
