Hi Pierre,
I can only repeat what the others wrote already, but with different words :)
Even in the "northern countries" internet access can be a problem if you
are in a rural area and have to use your mobile phone to connect to the
internet. JOSM does everything it can to support that.
JOSM caches background tiles (i.e. imagery), but only for the zoom
levels you used before. I have a workflow with Mapserver
(http://mapserver.org/) to calculate tiles from other zoom levels, but
that is complicated and nothing for a plugin.
The OSM data itself is vector data and you need to download some data to
be able to edit it anyway, so you have everything you need to work
offline. JOSM has different styles to render that data (Edit -
Preferences - Map Settings - Map Paint Styles). Is it a certain
rendering style you are looking for? Or do you want to see an area that
is too large to download the data upfront?
To implement a rendering engine like your smartphone app in JOSM is not
feasible. But you can connect to one with WMS or TMS if you find one
that runs on your local machine. Can someone recommend a local service
that does that?
Regards,
Holger

Hi Dirk
What I suggest is that JOSM adapt to different operational
context out of our northern countries with high speed internet. To
navigate with OSM in JOSM should be as easier as smarthpone offline
applications for people that need to work offline because of bad /
expensive access to internet networks. My experience with
smarthpones applications is that they are reliable, they provide
fluidity. JOSM Caching is surely not as easy and reliable as these
offline maps. And badly, moving in an area with no internet
connection, you realize that your setups are not ok and you have no
background imagery.
I agree that Obf is not a standard. The best would be that one
standard emerge for offline vector files. In the meantime, what can
we do to adapt to all the countries / areas without high internet
inexpensive bandwith?

Re: Offline OSM vector file plugin to edit in the field - OBF vector

Smarthphones did provide us access to all of Haiti on OSMAnnd or
Maps.Me. Our team was able to store tracks and waypoints on our
phones. We did also use Mapillary and ODK tools. But at the end of
the day, we could not edit the data in JOSM, bringing in these
various infos to compare with the OSM map as a background. This,
even if I tried previously to cache OSM tiles for the area, I did
not have access to these tiles while in the field with no internet
access. A cache could be a solution. A better solution is to Add an
Offline OSM Vector map plugin to JOSM. This would be a great
enhancement for OSM contributors that experience difficulty to
access data online.
I don't understand what you request at all.
- JOSM has tile caches which usually are small, but you can increase
size - JOSM is an vector map editor - its main task is to display
vector data - JOSM can load stored offline data files in XML and also
PBF format
Everything already there.
