  2. Check if the property is already pending or has been rejected.
  3. Check if you can give a similar label and definition as an existing Wikipedia infobox parameter, or if it can be matched to an infobox, to or from which data can be transferred automatically. See WD:WikiProject Infoboxes for suggestions.
  4. Select the right datatype for the Property.
  5. Start writing the documentation based on the preload form below and add it in the appropriate section.

Creating the property

  1. Creation can be done after 1 week by a property creator or an administrator.

  • Necessary to show how a name was printed on a certain book (old spellings), or how a certain statement was represented on print (ex. "mid 18th to early 19th century").--Micru (talk) 14:39, 15 August 2014 (UTC)
  • Symbol support vote.svg Support I've actually just suggested the need for something similar for dates. A lot of images I was uploading for the British Library recently had dates like "Mid 17th century to early 18th century". We can express that currently as 1780 (1730-1830), but we're losing information, and somebody else with specialist knowledge might have chosen different date ranges. So it's information that it would be a good thing to have a mechanism to store. I don't know whether "Printed as" is better or worse than "in orginal source", but I think it is functionality that we should have. Jheald (talk) 16:28, 15 August 2014 (UTC)
  • Pictogram voting comment.svg Comment Similarly to (OBSOLETE) title (use P1476) (P357) we should use "By Statement" like Open Library does it. Example The duel, and other stories, "by Anton Chekhov, from the Russian by Constance Garnett". (Otherwise we would need to add a qualifier for the translator, 2nd author etc.) --Kolja21 (talk) 11:01, 20 August 2014 (UTC)
  • Pictogram voting comment.svg Comment Datatype: "Monolingual-text" might be better. --Kolja21 (talk) 16:29, 12 September 2014 (UTC)
  • Pictogram voting comment.svg Comment musicbrainz calles this an artist attribution which would be a better lable since it then would also apply to other kinds of creative works. and it, of course shouldn't be a multilingual variable since one issue of a printed book should only state a single language. if not there could be multiple modifiers.--Shisma (talk) 11:15, 25 September 2014 (UTC)
  • Pictogram voting comment.svg Comment I think {(OBSOLETE) quote (use P1683 ) (P387) can be used for this as a qualifier for date statements etc. to preserve the exact wording but still have the ability to add info to timelines etc. Filceolaire (talk) 21:43, 31 October 2014 (UTC)
  • Symbol support vote.svg Support but rename to "original wording" and add aliases "printed as", "originally printed as", "author statement". I haven't seen the term "By Statement" in cataloging practice. "Attribution" could be added as alias, but it involves more scholarly activities of trying to figure out who created a certain work, with various outcomes (eg "formerly attributed to", "mis-attributed to", "in the style of", "following", "studio of", "workshop of" etc) --Vladimir Alexiev (talk) 10:04, 25 March 2015 (UTC)

  • Symbol oppose vote.svg Oppose @Koavf: this is not properly modeled.

Assuming that sales level designations are comparable across certification authorities, you need to:

    • create items to represent the different levels, eg Double_platinum currently redirects
    • create a property "Sales level" (alias "Sales certification") that will use the different levels
    • create a property "Certified by" to be used as qualifier on "Sales level" and hold the certifying agency

lyrics derived from[edit]

Data type Item

musical works

Special values (having specialized validation schemes): Persons, Taxons
Allowed values all
Example item and value Twinkle Twinkle Little Star (Q1058356) => The Star (Q18336412)
Proposed by Mvolz (talk)

These two properties are needed for pieces of music/ songs where either the lyrics or the melody or both comes from another work. For instance, the children's songs Twinkle Twinkle Little Star (Q1058356), Baa, Baa, Black Sheep (Q552300), Altijd is Kortjakje ziek (Q18336199) and Alphabet song (Q931920) all have the same melody as Ah! vous dirais-je, Maman (Q18336185). And the melody was also the theme of several works of classical music, such as Variations on a Nursery Tune (Q7915823) and Twelve Variations on "Ah vous dirai-je, Maman" (Q2603975). The same is true for lyrics as well; it is relatively common for a song to be produced with lyrics from a previously published poem. For instance, the lyrics of Twinkle Twinkle Little Star (Q1058356) are from the poem The Star (Q18336412).Mvolz (talk) 22:45, 21 October 2014 (UTC)

Symbol support vote.svg Support Seems reasonable to me. Would the alternative would be to use based on (P144) or not express the relationship in wikidata? --Mike Linksvayer (talk) 01:05, 22 October 2014 (UTC)

  • I think based on (P144) is better for this as it also covers songs where the poem has had minor alterations so I will Symbol oppose vote.svg Oppose this. Filceolaire (talk) 21:58, 31 October 2014 (UTC)
@Filceolaire:: The problem is that based on (P144) doesn't semantically distinguish between the elements of the song it's based on (i.e. melody or lyrics, which are distinct components). I agree though that most aren't completely intact, although for the most part this involves repetition of lines as a refrain. I've changed it to "lyrics derived from"- @Mike Linksvayer:, does that sound reasonable to you? Mvolz (talk) 22:50, 2 November 2014 (UTC)
I'm afraid not. You can always use applies to part (P518) as a qualifier to based on (P144) if need be. I really don't think we need another property. Filceolaire (talk) 20:27, 3 November 2014 (UTC)
@Mvolz:, @Filceolaire: it seems useful to semantically distinguish which elements of another work a song is based on. Whether to do this with new properties or with qualifiers, I don't know. Are there general guidelines for wikidata on the use of qualifiers instead of new properties? And to make sure I understand use of applies to part (P518) as qualifier for these cases, value would be Lyrics (Q602446) or melody (Q170412)? Mike Linksvayer (talk) 17:52, 5 November 2014 (UTC)
I am actually in favour of a dedicated property for cases where a melody is reused. I would only use based on (P144) for applies to part (P518):Lyrics (Q602446). Filceolaire (talk) 19:14, 5 November 2014 (UTC)
Can you help me understand the distinction? Is it that when a melody is used, it would be incorrect to state that the work is based on the melody, but when lyrics are used, it is correct to state that the work is based on the lyrics? Or some other reason a new property is best for one, qualifier for other? Mike Linksvayer (talk) 03:58, 6 November 2014 (UTC)
Mike Linksvayer: When a new song is TTTO it usually reuses the tune without changing it so Danny Boy::TTTO:Derry Air. The tune of Danny Boy is not based on it is the actual Derry Air. Stories or songs which are based on other stories or songs will change things a lot more than that so I Symbol oppose vote.svg Oppose a lyrics derived from property.

Example item and value O Holy Night (Q7073262) => O Holy Night (Q128008)
Proposed by Sweet kate (talk)

In trying to standardize data for Wikidata:WikiProject_Music I'm realizing there needs to be a music equivalent of edition or translation of (P629) in the way Wikidata:WikiProject_Books uses that property. For instance, MusicBrainz distinguishes between the composition itself (at the work level, like O Holy Night here and an individual recorded performance of it, like the single O Holy Night (Q7073262) performed by Ladywell Primary School (Q6470821). Rather than add the composer and lyricist for every single recording of this, they should just link to the primary original composition. Sweet kate (talk) 04:35, 9 December 2014 (UTC)

  • Pictogram voting comment.svg Comment I am in support of a "recording of" property, but how exactly is release (Q2031291) being defined here? It seems to be a different usage than what MusicBrainz has. Given that the proposed analogy is to edition or translation of (P629), which apparently mixes text translations with book printings, perhaps in that sense it is appropriate to mix recordings with releases. My preference, though, would be to differentiate a derivative creative/intellectual work from a product issuing. Perhaps this is beyond the scope of this discussion, though.

Pictogram voting comment.svg Comment Might this be better as a generic property such as named as, where the name of the target item, at the time the claim was valid, would be specified. Companies change their names for example, e.g. RIM became Blackberry, but should be referred to as RIM if that was what it was called at the time. Essentially, this is how simple wikilink templates work in wikipedia, you can provide an alternative name to be displayed instead of the article name. Danrok (talk) 14:58, 4 January 2015 (UTC)

Anonymous works qualifiers[edit]

Museums and other collections have quite a few paintings for which the author is anonymous (Q4233718). To make this a bit more specific, they use qualifiers. I brought this up at Wikidata talk:WikiProject Visual arts#Anonymous works and feedback was positive. I propose to create these properties. For completeness sake I'll paste the original message.

We have anonymous (Q4233718) to be used with creator (P170). Usually we have a bit of information about this unknown author we want to include as a qualifier. The Rijksmuseum (Q190804) was so kind to share their collection manual. It's a 100+ document touching onto a lot of problems we face too, including anonymous works. I would propose to create the missing properties so we can properly qualify anonymous works. I'll list them here, between () is the Dutch original:

  • Attributed to (toegeschreven aan): object is not signed and there is a certain amount of uncertainty who the author is.
  • Workshop of (atelier van): to be used if the object was probably created by students or employees of the artist in the same workshop, possibly with help of the named artist.
  • Follower of (navolger van): unknown artists who works in the manner of the named artist.
  • Circle of (omgeving van): objects by an unknown author who lived in the same time as the named author in a similar style, possibly a follower or someone who had contact with the named artist.
  • Manner of (manier van): objects in similar style as the named author, but not necessary from the same period.
  • Forgery after (vervalsing naar): Forgeries trying to appear to be the work of the named author.
  • Possibly (mogelijk): To be used with objects with a bigger uncertainty about the author.
  • School of (School van): Unknown author with a style influenced by the known author or circle, active in the same period, but a student or follower
