- create a data-derived entity and pull in columns for element, biological age, and lab_nr
- add extra columns:
Starting from the assumption that there is one bone for each sample, and the information from the associated paper that all bones in this dataset are from harp seals: I add extra columns, using the internal-to-this-dataset holding value of 1 fortaxon_idthat will. in conjunction to the other entities that usetaxon_id, add the information that all bones in this dataset are harp seals:
| New Column Name | Source Column |
|---|---|
| abundance | 1 |
| taxon_id | 1 |
- add join to the Example dataset mapping/AFL Radiocarbon Data mapping/Entity abundance_element on the element to fills the abundance_element_id column of this entity with the appropriate numbers for each bone from the system_id row of the Example dataset mapping/AFL Radiocarbon Data mapping/Entity abundance_element sheet. (errors for this on 2026-04-22, message sent to Roger)
- create a second join to link the various taxa information to the abundances (waiting for the first join’s errors to be solved before attempting this)
