A proposal for standardizing TSV files

Thank you. I read the W3C recommendation, as well as the referenced
documents. I drafted a comparison here:
I think the standards are trying to do something a bit different, and are
actually pretty complementary. tsvx is designed to facilitate compatibility
between applications for internal data analysis and BI work. It is a
prescriptive standard. It says how files ought to be escaped and formatted.
The W3C CSV for the Web group appears to be doing exactly what name implies
-- provide descriptive metadata for public redistribution of datasets on
the web, especially for use on the semantic web. It is a descriptive
standard designed to work with all essentially all tabular data files. A
tsvx file could certainly be described with the W3C metadata if the
intention were external distribution.
Just to give the types of use cases I have internally:
- I have pipelines where I might have a dozen TSV files generated by
scripts working on data from MySQL, Vertica, and spreadsheets, all feeding
back to create reports. Before I switched to tsvx, scripts were brittle to
fairly modest format changes (e.g. adding a column), and had a bunch of
unnecessary logic parsing data types.
- Each time I import something into a tool I didn't create, I need to
click through a dialog letting it know what the delimiter is, and in
LibreOffice, reformat column types.
Adding W3C metadata files would add overhead for this type of work, rather
than reducing it, and would only provide benefit at the stage of the final
