Hi,
We have an open issue [1] on whether to support “union” types on columns. For example, should we enable metadata to contain:
"datatype": [ "integer", { "base": "string", "format": "(NE|NP|SUPP)" } ]
to enable a column to contain either integers or the special strings “NE”, “NP” or “SUPP”. We have one really well documented example of why this would be useful [2] but would be happier with introducing this additional complexity if we had more examples where this would be useful.
We need to make a decision before the next round of document releases (early June).
Please tell us what you think either here on the list or on the Github issue.
Thanks,
Jeni
