Other tags that are already in use

User:Emka 19:10, 10 June 2009

Yes. I use 'phone' rather than 'contact:phone' because that's what most other mappers do. This is no coincidence. It's simpler. I generally disapprove of most proposals to introduce "namespaces". While they have the feel of something nice and rational and organised, that comes at a price. Tags are supposed to be simple. We're not developing a programming language here. New mappers have to learn to type these things in and remember them. The 'contact:' prefix offers very little real benefit but makes a tag much less simple.

Yes you are right, I also don't use the contact:-prefix, but afaik it is pushed by the JOSM default preset-template. --Fabi2 04:40, 17 March 2012 (UTC)

Types of phone numbers

What do you think about tagging various types of phone numbers? Like mobile phone (or cell phone), fixed phone or sip phone for example. I thought:

  • contact:phone:fixed=1234
  • contact:phone:mobile=1234

I like it, especially mobile phones are in wide use and are often given together with a fixed phone number.--Scai 09:20, 22 September 2010 (BST)
Drowning in colon characters. How about good old simple tags like phone=* ...and maybe mobilephone=* ? -- Harry Wood 11:38, 22 September 2010 (BST)

More than one phone number

When a business has more than one phone number, what's the best way to capture this?

  • adding a contact:phone for each number
  • including all phone numbers in contact:phone

you can't add several identical tags, so probably something like contact:phone=phone1;phone2;phone3 --Richlv 19:45, 17 December 2010 (UTC)
Each business has several phone numbers...This is usually solved by a central phone number. (Wow. What a low level of problem solving). --Lulu-Ann 12:40, 21 December 2010 (UTC)


A webcam shall be a means to contact somebody? What are you planning, jumping up and down in front of the webcam, hoping to catch some attention? Lulu-Ann

I confirm. Webcams are normaly not a communication-channel--CMartin (talk) 17:37, 26 August 2014 (UTC)

additional forms of communication

i think we could add some more forms of communication:

  1. contact:skype
  2. contact:twitter
  3. contact:facebook

what's your opinion?

I agree. Gallaecio 19:52, 27 July 2011 (BST)
I certainly agree for the Facebook page. Must have. These are now often used instead of a Website home page. --Neil Dewhurst, Lyon France (talk) 08:31, 18 September 2013 (UTC)
I propose to add a social network VKontakte with key contact:vk --Cvb (talk)


Many small shop is known by owners name, I think contact:name would be the best way to tag. --BáthoryPéter 11:14, 28 July 2011 (BST)

Isn't operator=* usable? --phobie m d 21:49, 28 July 2011 (BST)

Deprecate this tag family

Stats (taginfo) and usage (editors presets) show that the old tags without the prefix "contact:" remain more popular even after two years of coexistence. After a discussion on the tagging list, I suggest to deprecate this tag serie on the wiki and recommand the old but simple keys.--Pieren 22:13, 1 May 2012 (BST)

AGREE! for the reasons given in the discussion above -- Harry Wood 01:41, 12 September 2012 (BST)
I think it is useful to maintain the namespace setaside, but NOT for general mapping use; rather as a reserved namespace to support content transformation, that is "contact:phone" as a synonym for "phone" for data conversion purposes but not for user mapping purposes. To this end, suggest creating a bot to revise instances of "contact:phone" to "phone" where "phone" is not currently in use, and to highlight where both are present for manual resolution. This would also mean retiring this page and creating a few wiki redirects. --Ceyockey (talk) 15:39, 3 April 2015 (UTC)

conact:housenumber / Bremen Schema / extended Karlsruhe Schema

I recently started to discuss to introduce the tagging-scheme contact:housenumber as the extended Karlsruhe Schema. The Discussion is here Talk:Addresses#conact:housenumber_.2F_Bremen_Schema_.2F_extended_Karlsruhe_Schema. --Cracklinrain (talk) 00:50, 20 June 2013 (UTC)
