Tagging scheme to describe historic structures/areas/elements.

Why we need new historical tagging?

The historical workgroup is an initiative of the Italian OSM community to bring in the project features for the most diffused types of cultural heritage in Europe and in the world. At now (half 2009), OSM lacks of more or less 10 types of cultural evidences, more or less diffused in all the continents. This consideration has been raised after the first ArchaeoMapping Party of the OSM history: Pompei 2008 (08-12-08). In pills: OSM is used for almost all applications of cartography, and now we want to enable OSM to be used also for historic heritage knowing - conservation - turism management.

The 2 logos are from Wikimedia Commons, and are used for "Finnish road sign no. 772 a. Museum or historic building"; it's in public domain because it is a part of a decision or a statement by an authority or a public body of Finland.

Topology

The most popular question after this kind of tagging proposal is

Why have you proposed some features as "new", when we have already them? For example, for roman bridges, you have proposed 

historic = bridge
bridge_type = viaduct
culture = roman

when we could have for example 

brige = yes
highway = path
historic = yes

that could be use, avoiding to introduce "historic = bridge" into database.

Answer: We need to strongly distinguish actual and suitable features from past ad historic ones. Probably, if I query the OSM database for all "bridge = yes", mostly I don't want the historical bridges (unsuitable for cars); in the same time, if I query database for "historic = bridge", i get them without adding any other query (while in the other case I must query for "bridge = yes" + "historic = yes"). Moreover, in the proposed model, the tag bridge_type contains the ancient use destination of the bridge. For example, a bridge that was built to carry a road and now is suitable today only for pedestrian, could be tagged as "historic = bridge" + "bridge_type = viaduct" + "highway = pedestrian" + "culture = roman". For the same reason, the use of historic = yes should be reduced, because searching for a "main" tag should not give a results including historic features.

So, the main problem is that the historic=* tag is more complex that other tags, because it represents features of the past, and mostly not usable today for they original ancient purpose. For this reason, all the historic features must be excluded from simply queries, which must give only actual features.

Problem: conventions to express the historical period

So, they're really a lot of features. What can we do? A problem remains open: how to distinguish building time.

Datation with period

historic = megalith
period = neolithic

Datation with date

historic = megalith
start_date = 3100 BC

or, for a Pompeii fountain 

historic = yes
amenity = drinking_water
date = 78-08-24
