[Tagging] Date formatting proposal
I'm posting here a link to a proposal for date formatting that I just added to the start_date wiki page: http://wiki.openstreetmap.org/wiki/Key:start_date The motivator was the discovery of many tag values of unfeasible heterogeneity in start_date. Taginfo reports 18313 usages (2814 distinct), of which these are examples of values other than simple 4-digit years[1]: 1986-08-21 29/09/2006 05/01/2005 2002-12-31 03/12/2004 2001-07-12 20101012 Nov␣2007 1.1.2012 1966␣restauriert 0200-12-29 0085-12-12 4.12.10 Spring␣2010 -2000 08.2010 18.␣jahrh. 0008-09-16 2009-09-10␣09:00:00␣+0200 1966-08-XX 19th␣century February␣2000 2007-XX-XX 1700-talet 1960s c.␣1903 1758;␣1909 12.␣April␣2008 1869-19?? Early␣18th␣century 1984;1988;1986;1985;1989;1989;1986 Summer␣of␣2009 13/07/2006;␣05/01/2005 circa␣1820 5/1923␣-␣10/1926 623AD Late␣11th␣to␣early␣12th␣century -3 1878 1959-09-01;1960-08-19;1960-08-31;2006-10-26 XVème 3100␣BC ... and my favourite: octobre So it's clear there's a demand for: exact dates; general approximations; approximations to the month, season, century; before date and after date; early period and late period, maybe also mid period; date ranges; multiple values; BC and AD. We can probably ignore: exact times. They should go in their own time tags, if anyone wants them. In my own historic photo tagging I have found numerous captions that date pictures with varying degrees of precision using similar non-standard means. I then turn these into a date tag, trying to capture as much of that vague richness as possible. The proposed scheme is similar to what I have been using and parsing successfully. Comments welcome!

[Tagging] landuse for arboretum
i'm currently doing the boundaries for the Pine Hollow Arboretum south of Albany NY. none of the current landuse/natural tags seem quite appropriate. landuse=forest and natural= wood are closest, but i'd hesitate to use either without a subtype tag indicating that it's specifically an arboretum (denoting a site where trees in a natural setting, not necessarily local to the site, may be viewed.) an arboretum sort of sits in the middle between the two classifications, it's managed in a limited way in that there are intentional plantings of interesting trees, but the management is limited in that dead trees may not be cleared, etc. i'm using landuse=forest for now, but would like to invite discussion of which main tag is really appropriate and what subtype tag might be used. richard ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Wouldn't it be covered by leisure=garden? ie Place where flowers and other plants are grown in a decorative and structured manner or for scientific purposes. Its just it specifically focuses on trees, as opposed to flowers or other plants. Maybe with a subtag to specify it is an arboretum? There is a proposal for extra tags for garden types: http://wiki.openstreetmap.org/wiki/Proposed_features/Garden_specification Though I do think that landuse=forest vs natural=wood is a mess. Better to just use one tag for any area covered by trees, then use extra tags for whether it is 'natural' or managed, what it is used for, and what types of trees etc. ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Please follow up either here or on the Discussion page on the wiki. IMHO the right answer is ISO8601: http://en.wikipedia.org/wiki/ISO_8601 It can be as precise as we need, from a year only, down to a fraction of a second. My suggestion would be to use it as follows: 2010 (Year only) 2010-11 (Year/month) 2010-11-11 (Year/month/day) 2010-11-11T08 (Year/month/day/hour) 2010-11-11T08:57 (Year/month/day/hour/minute) The key points when specifying the use of ISO8601 would be to use the human-readable form (with dashes for date separators, and colons for time separators, and T between date and time), to include leading zeroes for date or time parts 10, and to stipulate that the time is the local time in the region occupied by the node, way or area.
