=== Technical ideas
Keywords can change over time for a tracker, so collecting them
should not depend on a fixed database schema.

On idea is to save them as a JSON text in a {{{keywords}}} field.
This maybe given almost directly to a webbased display system
based on javascript.
The drawback is that SQL cannot be used to query by keyword details,
but advanced database functions can be used for improving this situation
like [[https://www.sqlite.org/json1.html|SQlite' JSON1 extension]].

The same could be used for priorities and status values, as they
could also change.
