[Tagging] Opening hours too long for OSM

[OSMDoudou]

> opening_hours="see the web site."

If one doesn't intend to tag the opening hours, then one better uses the "website" tag [1] and not the "opening_hours" one.

But it would be a pity one doesn't document opening hours due to a technical limitation.

As to improving (thinking out loud here...), couldn't one envisage an enhancement to document opening hours with "opening_hours:jan_sep=08:00-12:00" and "opening_hours:ph::jan_sep=08:00-16:00" if the place is opened in the afternoon only on public holidays, for examples ?

Of course, data consumers must be adapted, but it doesn't break anything or doesn't require to change the technical limitation.

And maybe a more radical improvement and definitive solution would be to go towards a semantic web [2], so the data doesn't need to be in the OSM database but there is a link to query data hosted outside OSM. A bit like for "wikidata" tag. [3]
