Free text, should be a unique ID\n    - `data_table`: ID for the data table being described. Free text, should be a unique ID.\n    - `data_column`: Column name. Free text, should be a unique ID.\n    - `data_type`: Type of the data in that column. Control vocabulary.

Free text, should be a unique ID\n    - `data_table`: ID for the data table being described. Free text, should be a unique ID.

Either a column_name or variable_name to cover wide and long tables\n    - `data_product`: ID for the dataset being described. Free text, should be a unique ID\n    - `data_table`: ID for the data table being described. Free text, should be a unique ID. Could be NA, suggesting meta applies to entire product\n    - `provided_variable`: variable name from the original dataset, often column header matching `data_column` in `data_meta`\n    - `variable`: common vocabulary that is being mapped to this should reference some external URI\n\nvariable_location|data_product|data_table|provided_variable|variable\n----------------|------------|------------|-----------------|--------\ncolumn_name|ISCN3|layer|13c (‰)|13c\ncolumn_name|ISCN3|layer|14c (‰)|14c\ncolumn_name|ISCN3|layer|14c_sigma (‰)|14c\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fesipfed%2Fsoi_harmonization","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fesipfed%2Fsoi_harmonization","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fesipfed%2Fsoi_harmonization/lists"}
