hsv5 VS ssv

I've pondered exactly that. After a previous HN thread, I tried my hand at writing a specification that was minimal as possible but followed HTML5. For example many end tags are optional like `tr` and `td` end tags. Though I pulled in RDFa for richer data types.

Here's the GitHub repo for what I like to call HSV5: https://github.com/elcritch/hsv5/blob/main/README.md ;)

And an example of the smallest _valid_ HTML table format:

Somewhat related, I was toying around with what an html5 based csv alternative could look like and called it hsv5 partly as a play on json5 and hdf5.

So far it's just a python library, but I'm planning on adding editor plugins at least for vim, vscode and maybe emacs, libraries for additional languages, and maybe some cli commands for it.

One distinction from the OP is the delimiters also include a tab (for fields) or newline (for records) by default (but not in "compact" mode). That has the benefit that the files are at least readable with editors and pagers that aren't aware of the format.
