Dear COL team,

I’m trying to download the ColDP Archive of THE COL CHECKLIST VERSION 2021-09-21 on this page: https://www.catalogueoflife.org/data/download. However, the actual download link https://download.catalogueoflife.org/col/monthly/2021-09-21_coldp.zip is not working and returns 404. I am able to find another data file here: https://download.catalogueoflife.org/col/. The most recent one I believe is https://download.catalogueoflife.org/col/latest_coldp.zip with a timestamp of 2021-08-27 11:00.

According to the description of ColDP file format here: https://www.catalogueoflife.org/about/colusage#data-formats. The ZIP archive is supposed to bundle the following delimited text files:

• Name
• NameRelation
• Taxon
• Synonym
• NameUsage
• Reference
• TypeMaterial
• Distribution
• VernacularName
• Media
• SpeciesInteraction
• TaxonConceptRelation
• SpeciesEstimate
• Treatments

However, In the latest_coldp.zip I downloaded, I got something different.

$zipinfo -1 latest_coldp.zip  

• NameUsage.tsv
• NameRelation.tsv
• TypeMaterial.tsv
• VernacularName.tsv
• Distribution.tsv
• Media.tsv
• SpeciesEstimate.tsv
• SpeciesInteraction.tsv
• TaxonConceptRelation.tsv
• Reference.tsv
• reference.json (<- this is new)

Some important files are missing.

• Name
• Taxon
• Synomym
• Treatments

Could you please help understand it? Thanks.

Best regards,

Tiejun CHENG, Ph.D.
