Pull request overview
Updates OBIS-specific Darwin Core guidance to capture how “Genus sp.” / “Genus spp.” identifications should be represented using DwC terms (per DwC examples and dataset review feedback).
Changes:
- Adds guidance to record “sp.” / “spp.” in
verbatimTaxonRankwhen present in the source record. - Clarifies that
taxonRankshould remaingenusandscientificNameshould contain only the genus for these informal identifications. - Mentions preserving the original identification in
verbatimIdentification.

| **In case of low confidence identifications**, and the scientific name contains qualifiers such as _cf._, _?_ or _aff._, then this name should go in `identificationQualifier`, and `scientificName` should contain the name of the lowest possible taxon rank that refers to the most accurate identification. E.g. if the specimen was accurately identified down to genus level, but not species level, then the scientificName should contain the name of the genus, the scientificNameID should contain the LSID the genus and the `identificationQualifier` should contain the low confidence species name combined with _?_ or other qualifiers. The table below shows a few examples: | ||

| **For identifications such as _Genus sp._ or _Genus spp._**, the abbreviation (e.g. _sp._, _spp._) may be recorded in [`verbatimTaxonRank`](http://rs.tdwg.org/dwc/terms/verbatimTaxonRank) if it appears in the original record. As these are not formal taxon ranks, `taxonRank` should be set to `genus`, and `scientificName` should contain only the genus name. If needed, the full original identification can be preserved in `verbatimIdentification`. |
