    Data formatEdit

    Currently, the property is set to the data type URL, even though the property discussion had advised to use IRI. In practice, this means that email addresses can only be entered in mailto: format, and all uses of the property so far are listed as constraint violations. --Daniel Mietchen (talk) 23:29, 1 August 2015 (UTC)

    I added "mailto:" to the pattern. --- Jura 10:49, 25 August 2015 (UTC)


    Currently, this property is used for a series of personal email addresses. As the property isn't meant to be used for persons, these would need to be removed. --- Jura 07:19, 28 August 2015 (UTC)

    Interestingly, the number reduces as items get deleted for lack of notability. --- Jura 06:02, 3 September 2015 (UTC)

    @Jura1: Well that's a shame, we add Twitter accounts for people but not email accounts? Thibaut120094 (talk) 15:14, 26 September 2015 (UTC)
    Twitter is for output, email addresses end up being used for spamming .. Besides, I'm not sure if people would agree to have their address listed here. --- Jura 11:43, 27 September 2015 (UTC)
    @Jura1: Can you point to information about Wikidata being only for "broadcast information"? Because it isn't applied consistently, e.g. phone number (P1329). And email addresses of officials doesn't seem productive. Dispenser (talk) 21:45, 21 May 2016 (UTC)
    Is Wikidata? I don't know. Both properties tend to attract lots of trash. If you don't maintain it, it's bound to go that way. Both properties have been made for Wikivoyage which has anything but entries about people.

    Change datatype and formattingEdit

    {{Editrequest}} I propose to:

    1. change back the data type from URL to string
    2. change the regex removing the initial "mailto:"
    3. add formatter URL (P1630) with "mailto:$1"
    4. change all data from "" to ""

    The reason is that this property can't be used correctly in it.voy as we want to show the email with a link to mailto: URI and you can't do [mailto:EMAILADDRESS EMAILADDRESS] right now. Filceolaire and Pyfisch proposed this change but the first one died. I'd like to know why they proposed to change the datatype --★ → Airon 90 15:46, 1 September 2016 (UTC)

      Comment This is a breaking change for data consumers and needs greater discussion and announcement. The first step also involves the developers and I believe it can be done after the fourth one (not truth). Matěj Suchánek (talk) 07:21, 19 May 2017 (UTC)
    @Matěj Suchánek: Ok, how can I start such discussion? I want to do this kind of work --★ → Airon 90 10:22, 22 August 2017 (UTC)

    Uses for people?Edit

    Although this property is originally intended to be used for Wikivoyage listing, PubMed and many database do include plenty of e-mail data of authors. This may be another way to identify authors (as no two people may share one same private e-mail address). I propose to remove the conflict of constraint about people. Thought?--GZWDer (talk) 20:19, 20 August 2017 (UTC)

    Of course, it is useful for people too. --Infovarius (talk) 09:04, 22 August 2017 (UTC)
    Yes but with respect of privacy: no personal emails, yes institutional emails --★ → Airon 90 10:21, 22 August 2017 (UTC)
    What anti-spam measures do you suggest? It seems fairly rare these days that people add links to email addresses and most official website indicate some preferred way of contact.
    --- Jura 07:28, 23 August 2017 (UTC)
    If available, why not adding data to the items? I think about politicians: usually they have their own official email address --★ → Airon 90 08:44, 23 August 2017 (UTC)
    I'm not contesting that people have email address, phone numbers etc.
    --- Jura 08:47, 23 August 2017 (UTC)
    @Airon90: However the email addresses listed in PubMed, like this one, are clearly researchers' personal emails. If they're allowed in PubMed, I don't think why it can not be allowed here.--GZWDer (talk) 17:34, 25 August 2017 (UTC)
    This was created for Wikivoyages' needs, not sure if they would still need it. Can you respond to my question?
    --- Jura 05:47, 6 September 2017 (UTC)
    Why can email addresses be allowed in PubMed?--GZWDer (talk) 07:40, 6 September 2017 (UTC)

    Uses for Journals or PublicationsEdit

    I would like to see the constraints broadened to allow usage of this property on Journals and Publications. Example of one for contacting editorial staff for a Scientific Journal: Thadguidry (talk) 17:09, 23 July 2018 (UTC)

    This should really be an identifier rather than a normal propertyEdit

    Who can alter this? --Liuxinyu970226 (talk) 08:28, 23 February 2019 (UTC)


    Given the personal nature of this property i'll like to add a 'citation needed' constraint. Trade (talk) 20:59, 14 May 2019 (UTC)
