Broad scope

Based on this discussion last month, should we broad the scope of this property for other things than music charts? Some languages need to be adjusted. @Jheald, Jura1, Pasleim: pinging since the discussion sadly died. Sjoerd de Bruin (talk) 18:56, 17 February 2018 (UTC)

I would prefer not to broaden the scope of this one. I think its quite a specific property for quite a specific concept, and one that works well. Jheald (talk) 20:59, 17 February 2018 (UTC)

Covers, and other issues

I'm planning to import no. 1 Billboard Hot 100 rankings from the English Wikipedia list articles. Issues:

• How are covers represented? Is the data added to the item for the original song, or is a new item created for the cover version?
• How should singles containing two songs be represented?
  • Should each song have the data added separately? (Should an item exist representing the single, with another two items representing the songs?)
  • Is this different for singles with an A-side and a B-side, as opposed to two A-sides?
  • Do digital singles' B-sides qualify as actual B-sides?

Jc86035 (talk) 17:02, 18 February 2018 (UTC)

Also, why isn't point in time (P585) an allowed qualifier? Shouldn't the "chart date" be listed alongside the tracking period(s)? (Billboard has different tracking periods for sales/streaming and airplay, so this makes only allowing those three qualifiers a bit more complicated.) Jc86035 (talk) 17:05, 18 February 2018 (UTC)

Covers should have their own item. With a based on (P144) to the original. Singles should have 3 (or later in the CD age 3+) items: 1 for the single and 1 for each song. Linked to each other with has part(s) (P527)/part of (P361) (depending on what the item is about). Is it the single that's in the Billboard 100 or a song? point in time (P585) isn't a qualifier because we have start time (P580) and end time (P582) to mark the period. Mbch331 (talk) 17:21, 18 February 2018 (UTC)

@Mbch331: Which period is used, for Billboard Hot 100 specifically? Currently the radio airplay period is Monday to Sunday and the other data is from Friday to Thursday; it would make more sense to me to put the methodology information on the item for the chart than in every chart position statement. Jc86035 (talk) 06:03, 19 February 2018 (UTC)

Furthermore, for data after the inclusion of digital downloads and streaming, should there still be separate items for the single and the song; and should cover versions which are counted as the same as the original song by Billboard (i.e. Despacito (Justin Bieber) and Perfect Duet (Beyoncé)) have the data on the cover version or the original, or whichever version Billboard credits the chart position to? Jc86035 (talk) 06:12, 19 February 2018 (UTC)

If the cover is made by a different artist, then in the eyes of Wikidata they are different concepts and thus different items. The data applies to the version Billboard uses. But since you're importing from enwiki, do you have an example of a list article you are planning to use? That would make it easier to answer your questions. Mbch331 (talk) 06:41, 19 February 2018 (UTC)

@Mbch331: I'll use 1972, 1996 and 2018 as examples. 1972 for the singles with B-sides, 1996 for the double A-sides and remixes (i.e. Macarena (Q1149738)), and 2018 for the singles without physical versions and the weird crediting situation with Perfect (Q29051557). There are various points concerning the changes in methodology (tracking week, etc.) and the inclusion of non-singles, airplay, streaming, digital downloads and remixes in the English Wikipedia article. I'm not going to add reference statements straight from the lists (though some of them, e.g. 1987, do have multiple reliable secondary sources) but will add references (with URL, title, publisher, access date) in Billboard's https://www.billboard.com/charts/hot-100/1983-01-01 format. I've been trying to convert the tables into CSV.

For items like Bad Blood (Q19892111) (digital download single released as a remix of the original), does a new item need to be created for both the remix and the single, or is the remix the single, or are both of them considered the same as the original item? The current Wikidata item appears to be about the remix single. Jc86035 (talk) 08:01, 19 February 2018 (UTC)

@Mbch331: Should I put the start date and end date as both sets of dates (Monday–Sunday and Friday–Thursday), or the full range (Friday–Sunday after)? Or is it supposed to be the period that the chart was the latest chart published, or the period from the chart date to the day before the next chart date? I'll probably end up importing album chart positions first, since they're just less complicated in terms of data structure. Jc86035 (talk) 04:59, 21 February 2018 (UTC)
