[Tagging] historic tagging - graves, tombs

2011-02-01 Thread M∡rtin Koppenhoefer
How do you tag single (historic) burial places? I am currently looking
for a tagging scheme to structure these kind of places, but am unsure
about the wording.

My suggestions would be
* historic=grave
or
* historic=tomb

for the main tag. Subtags would then be

grave=pyramid
grave=mausoleum
grave=tumulus
grave=dolmen
grave=war_grave
grave=crypt
and others that you maybe name

and maybe also
grave=cenotaph

http://en.wikipedia.org/wiki/Mausoleum
http://en.wikipedia.org/wiki/Tumulus
http://en.wikipedia.org/wiki/Dolmen
http://en.wikipedia.org/wiki/War_grave
http://en.wikipedia.org/wiki/Crypt
http://en.wikipedia.org/wiki/Cenotaph

This could be combined with historic:civilization for better description.

What do you say about the wording? Would tomb or grave be suited better?

[Tagging] historic tagging, obelisks

2011-02-01 Thread M∡rtin Koppenhoefer
To tag obelisks I suggest

man_made=obelisk

an alternative could be

historic=obelisk

but some obelisks are actually not old, so historic might not yet be
an appropriate tag for them. In combination with historic:civilization
and historic:period they could still be clearly distinguished.
http://en.wikipedia.org/wiki/Obelisk

example for a not so old Obelisk:

Are there any objections? Otherwise I'll set up a proposal.

A grave tends to be a hole dug in the ground to bury one or more bodies, 
a tomb is more of a structure, so they are not mutually exclusive.


I would group pyramid, mausoleum, tumulus, dolmen and crypt as a tomb

grave=cenotaph doesn't feel right to me, usually there is not an actual 
burial there, it is more of a monument. 
historic=monument,monument=cenotaph seems better to me.


I am interested because I am working on a project for the Imperial War 
Museum improving the data held for memorials including war memorials, 
cenotaphs, grave memorials, street shrines, rolls of honour, church 
memorials such as windows etc. We are working on the memorials for 
1914-19 war at present. Most of these are historic=memorial to me, but 
historic=grave is interesting.

I see. I think that's the one I am after. I have addional complexity
as in some tumuli there is several graves (not sure if they are
graves, they are not dug into the earth but constructed chambers),
with separate entrances, and known under different names (one for the
tumulus and one for each burial place).

yes, it's not a place where actually a dead body was put, it is like
an "empty grave", though with similar appearance to a real grave. I
don't need this at the moment, so I suggest to keep it out from
grave/tomb (or better document your suggestion in monument).

OK, according to your comment I should better suggest historic=tomb to
tag bigger structures, right? For single graves we could have
historic=grave which would mark the actual place where a person is
buried. For bigger structures (collections=field of tombs/graves,
distinct part of a cemetary) there could be another tag (maybe what
you are after if tagging memorials like 1914-19). I also need this for
the whole structure (in my case it's several Etruscan necropoli). Not
sure if tagging these places like a cemetary would be appropriate. I
remember from Cairo Egypt that people were actually living inside the
ancient necropolis, so tagging them like an actual cemetary would be
confusing.

My (admittedly shallow) understanding was that there was some debate
about whether all tumuluses and dolmens were in fact tombs. This is an
instance where I think a flatter structure might be safer:

historic=tumulus
historic=dolmen
historic=stone_circle
historic=cromlich
historic=standing_stones

Having "pyramid" a subtag under "tomb" just feels wrong, also.

Definitely tomb rather than grave, in any case.

Definitely historic=obelisk, I think. It doesn't really matter if it's
*old*, it's still *historical*.

As that Wikipedia article says, its just a particular style/shape of 
monument or memorial.
So I think it would be best tagged as historic=monument or 
historic=memorial, plus a subtag for obelisk.

Maybe something like monument:style=obelisk ?

There's quite a few other monument/memorial styles that would be useful 
to tag, eg statue, fountain, spire etc.

I am not an expert either, but according to my knowledge tumuli and
dolmen are necessarily kind of tombs (if you can cite some text that
states the opposite I would indeed be interested). Maybe the
exceptions that didn't serve as burial place aren't to be considered
tumulus?

> historic=tumulus
> historic=dolmen
> historic=stone_circle
> historic=cromlich
> historic=standing_stones


the thing is that I expect the number of different burial structures
used in OSM to raise with the time, and having a general tag for these
kind of things and then subtag might ease the work with the data. On
the other hand I agree: if there are structures that are considered to
be dolmen or tumuli but are not intended for burial purposes this
systematics would not work.


> Having "pyramid" a subtag under "tomb" just feels wrong, also.

This because not all pyramids are used as burial places, or because
even the ones that were won't be called tomb? In the first case, you
simply wouldn't tag all pyramids as tombs, but the ones where a burial
took place (or was intended when they were built).


> Definitely tomb rather than grave, in any case.

This could be a way, but I am not yet convinced. Churches, temples and
towers are also monuments, but we don't tag them currently as subtypes
of monument. Indeed the tag historic=monument is very vague and
therefor not very useful IMHO.

Can you expand on the difference between memorial and monument? AFAIK
a monument states that an object is "monumental" = big, bigger then
human scale. Memorial is instead referring to a structure errected to
remind about someone/something. In OSM they are exclusive (you cannot
use both). I have the feeling that these 2 tags are broken by design,
but they are very useful, because beeing so generic you can use them
for lots of stuff ;-)

Maybe it would be better to use them as flags? Describe the features
with some tags, and add monument=yes (for monumental stuff) or
memorial=yes (for stuff to remind about something). It could also be
memorial=first_world_war (or memorial:topic=first_world_war)

such a long period of time that traditions changed over the period, but 
a tumulus was usually built for a single burial then often extended or 
reused for later burials, sometimes more than a thousand years later. 
Very rarely do the remains still survive, so usually the most you can 
say about a tumulus is that it exists in a specific place, not who or 
how many people were buried there or when. The style and shape gives 
information about the a final date it was last modified, but only to 
perhaps a 500 year and not much about when it was first used.

For single graves we could have

Yes, but in some cases multiple people are buried together, such as a 
family plot, and mass graves deserve a specific tag too. I would add 
some inscription info (probably not the full inscription we have a 255 
char limit I think). I add would add UKNIWM_ref=* for the UK National 
Inventory of War Memorials ref, so all other details could be looked up 
from there, though a more general ref might be better.

For bigger structures (collections=field of tombs/graves,
distinct part of a cemetary) there could be another tag (maybe what
you are after if tagging memorials like 1914-19).
Many of the memorials I'm interested in are not at the actual site of a

not all of them. A Las Vegas Obelisk is hardly to be called "historical".

usually you can already see this from the name (I will mainly tag
egyptian ones, so there will be no doubt). For columns I'd say that an
obelisk usually has 4 sides, while a column is round. I can't tell you
what a pillar is (wikipedia says it's a column), my first guesses were
that they stand for piers or pilasters, but they seem to be a kind of
column. An obelisk definitely has to be open above (not load bearing),
and probably not carrying a statue or something other then a "crest"
(not sure if this is the right term, it should mean vertical end,
probably ornamental / decorative). Of course these are later
additions, and egyptian originals simply ended in a point directed
towards the sky.

I think both monument and memorial are (usually) for structures in 
memory of something.
The difference is more about the relative importance - ie if its the 
most important one in the country, and famous etc, then its a monument. 
If its just for a fairly local event or single person, then its a memorial.
So not so much about the physical size, though monuments are usually 
bigger than memorials.

Then use extra tags to specify what it is in memory of

a tag for the relative importance/significance, eg is it just a village 
memorial, or is it of national importance.

we could have something like step_count for steps, i.e. tagging a
value (e.g. grave_count) for the amount of people buried including
"mass" and "several" for rough estimates.

would you have a need to tag places as both, memorial and grave the
same time? This would maybe speak against historic=grave.

I won't give it a dedicated place-tag actually, the ones in Cairo are
probably better described with place=suburb (according OSM-meaning as
"named part of the city" not as "suburban area") for the inhabited
place, and a different tag (from the historic-range) for the
historical structure. The necropolis I am mapping are not inhabited
and have never been to my knowledge --- hm, maybe place=necropolis is
not bad ;-), places do cover more then inhabited places in OSM (think
of islands, localities, etc.). Currently I was more thinking about
something like historic=archaeological_site, site_type=necropolis.

The page http://wiki.openstreetmap.org/wiki/Tag:historic%3Darchaeological_site
lists also
site_type=tumulus
field=yes
for places with several tumuli, but this doesn't completely cover the
necropolis I a mapping, as there are not only tumuli. necropolis would
be more generic and could be refined with mapping the distinct
features present inside the area.

think about the Eiffel tower in Paris. It is (IMHO) clearly a

While this sounds reasonable, it would still make mapping hard. E.g.
in Rome there is a lot of obelisks, and they are very easy to identify
;-), but tagging their original purpose or what they should remind of
might be disputed or hard to find out. For the obelisks that didn't
remain at their original site (like most of them) it might also be
confusing, and there might be 2 topics (the original intention and the
one of who moved it). Generally spoken, an obelisk (like a column) can
be read as a "phallus" and has the connotation of power and centre ---
similar to the stake in original cultures. It is used to mark a place
as important (connecting the earth with the sky, nature with the gods,
...). The topic can be expanded to a whole book (books expanding on
the meaning of this do indeed exist).

But I do think that you are right: they will in most cases be
monuments (historic=monument). This would IMHO support the idea to map
them with a tag that is not "historic" itself, i.e. man_made=obelisk
(pro: follows the man_made=tower logics) or building=obelisk (pro: is
already rendered ;-) ). Or use memorial:type=obelisk in conjunction.

yes, at least we could _recommend_ to not use true or 1 any more in

I see people classifying the Eiffel Tower as a monument on the web, but
in the branch of English I use, it isn't a monument, for the reasons
you give above.

Calling the Eiffel Tower a monument is an example of how English
changes. And people here are trying to capture English terms for things.

An obelisk is something you really want to map. I think the most striking thing
about them is how they stand out in the surroundings.

No key is really spot-on, well maybe landmark but that is used on seamaps to
mark prominent features on the horizon.

So how to tag prominent features on the streets and squares. I think that there
should be some general tag for all free standing columns and some special tag to
separate the obelisk.

My suggestion is man_made=column

There is alot in common between the columns and other prominent monuments and
such, like statues, fountains and different kinds of modern sculpture.
maybe man_made=sculpture is an even more general tag?

[Tagging] Feature Proposal - RFC - Site Relation

2011-02-01 Thread Josh Doe
The Relation:type=site proposal [1] has been around for over two
years, and I think it is a very useful relation, so I'd like to help
it get approved. Milliams is the original creator of the draft, though
I've cleaned up the proposal page and added some to the discussion,
and I'd like to bring your attention to it to get additional comments.

Please visit the proposal page [1] and add your comments to the
discussion. I've been using this relation for schools and playgrounds,
and I believe it is a needed addition to our tagging arsenal.

Thanks!
-Josh

Do you mean the documentation is vague? Then let's fix it.

My thinking in wanting columns, obelisks, memorials, monuments etc
grouped under "historic" is because they're thematically related. Who
is likely to want to see them on a map? Probably a tourist or someone
with a particular interest in history.

Dumping things under man_made=* isn't helpful because virtually
everything we map would be either man_made=* or natural=*. We need to
build smaller sets of things that work together.

Btw your Las Vegas example is clearly an exception. I certainly
wouldn't use the same tag for a real, historical obelisk and some sort
of advertising feature.

Re: [Tagging] [OSM-dev] capitals; normalizing true, yes and 1

2011-02-01 Thread Daniel Sabo
I would prefer we normalize in the actual database instead of coming up with a 
ton of transformations needed to convert the data to something meaningful. Bots 
tend to have unintended consequences though, so if you want to do it yourself I 
would just use XAPI to pull the data in to JOSM and change it by hand.

In this specific case it seems safe to convert capital=true -> capital=yes, but 
the other values I'm less sure what they were intending.
