This is likely to be covered by plugin hooks: #860 for the metadata and after investigating in #1042 it looks like the existing prepare_jinja2_environment hook may already be enough to load templates from the database.

Potential problem: the existing metadata.json format looks like this:

{ "title": "Custom title for your index page", "description": "Some description text can go here", "license": "ODbL", "license_url": "https://opendatacommons.org/licenses/odbl/", "databases": { "database1": { "source": "Alternative source", "source_url": "http://example.com/", "tables": { "example_table": { "description_html": "Custom <em>table</em> description", "license": "CC BY 3.0 US", "license_url": "https://creativecommons.org/licenses/by/3.0/us/" } } } } }

This doesn't make sense for metadata that is bundled with a specific database - there's no point in having the databases key, instead the content of database1 in the above example should be at the top level. This also means that if you rename the *.db file you won't have to edit its metadata at the same time.

Calling such an embedded file metadata.json when the shape is different could be confusing. Maybe call it database-metadata.json instead.

This would be a great feature to have!

One point of complexity: datasette can be used to bundle multiple .db files into a single "app".

I think that's OK. We could require that the datasette_files table is present in the first database file passed on the command-line. Or we could even construct a search path and consult multiple versions of the table spread across multiple files.

That said... any configuration that corresponds to a specific table should live in the same database file as that table.

Ditto for general metadata: if we have license/source information for a specific table or database that information should be able to live in the same .db file as the data.
