Module: Export::Coldp::Files::Name

Defined in:
lib/export/coldp/files/name.rb

Overview

The names table includes

  • All name strings, even if hanging (= not attached to OTUs/Taxa)

  • It contains strings that may be invalid OR valid

Future considerations

- see bottom, should we parameterize a CSV row add, is it performat?, it
would let us DRY all csv << , but it's also not dry to parameterize.
Probably OK as is.

TODO:

- [ ] refactor ref additions so that they happen at the aggregate level
- [ ] resolve the `.length` issue, what the heck is that needed for

Class Method Summary collapse

Class Method Details

.add_combinations(otu, csv, project_members, reference_csv) ⇒ Object

TODO: we probably have an issue where self is not included as a relationship and we need to inject it into the data?

.original_combination_names(otu) ⇒ Object

Valid original combinations are:

- species or genus group names
- valid names
- names with original combinations set
- names where cached != original_combination, i.e. it needs re-ification

As a test these should parse correctly in the Biodiversity wrapper as of 4/8/2025.
