Hi, David!
Gosh it's been a while....
Regarding the POI table, it's just defined in poi.c
(at "#define POI_DB_CREATE").
Adding some inline comments...:
CREATE TABLE poi (idmd5 TEXT, -- a unique ID-string
lat REAL, lon REAL, -- location
visibility REAL, -- 1=public, 0=personal
cat REAL, subcat REAL, -- index into menus
keywords TEXT, -- i.e. POI name
desc TEXT, -- description
price_range REAL, -- 1, 3, or 5
extended_open REAL, -- really a bool
creator TEXT, -- not used
bookmarked REAL, -- not used
user_rating REAL, -- not used
rating REAL, -- not used
user_comment TEXT); -- not used
Thought you might think it from the name, "idmd5" ID-string
is not an md5sum of anything; it's formed by concatenating
the textual forms of two large random numbers together,
but really it could be anything (a UUID would probably be
a better choice).
The price_range values 1, 3, and 5 correspond to
"budget", "medium", and "exclusive".
extended_open is the "extended opening hours" checkbox,
where 1=checked, 0=unchecked.
I'm not immediately sure whether any of the various
unused columns after extended_open were _ever used_
back when Marcus was developing the codebase as tangoGPS,
or if he just reserved them because he thought he might
use them for something at some point in the future....
In response to your other questions...:

No idea why the POI menu-items would be missing. The menus work
other than that--you have items for waypoints, route-finding,
route-planning, photos...?
I don't think there's any code to show/hide the "show POIs" item
or the "POIs" submenu.

It should still be in the release tarballs; it's autogenerated
when you run ./autogen.sh. There used to be a version in bzr that
basically had the contents of the README prepended to it;
that was removed mostly to let Autotools actually give us
as up-to-date a set of INSTALL instructions as it could
(and prepending our README onto INSTALL seemed redundant--
especially when the INSTALL file that Autotools generates says
"see the `README' file for instructions specific to this package"
at the top of the file).

Is that really all that needs to be changed?
Hm. While I'm looking at that... do you know if the "generator='JOSM'"
bit is actually necessary? (IIRC you just copied that verbatim
from Marcus' perl script?)

Does the above explanation change your mind any about the INSTALL file? ;)
