Have you thought about proposing a property, linking to a tabular data set, to store these rankings? (809kb for an item about a national football team seems very overkill.) Mahir256 (talk) 00:48, 1 December 2017 (UTC)

I don't know anything about Tabular Data :) Xaris333 (talk) 15:03, 1 December 2017 (UTC)
I strongly suggest you migrate all of this ranking information to tabular form. 1.3MB for an item about a single football team is absolutely unreasonable. I have linked to the documentation for tabular data sets in my previous comment, and there is precedent for creating properties to store tabular versions of existing properties, so I suggest that you propose such a property and move this information to respective tabular data sets for each football team once said property is created. Mahir256 (talk) 05:17, 8 December 2017 (UTC)
As I have said, I don't know anything about Tabular Data. I can't understand what is it. Xaris333 (talk) 08:51, 8 December 2017 (UTC)
@Yurik:, since you developed the documentation to which I linked earlier, and @S-1-5-7, ArthurPSmith, Pasleim, Yair rand, Jura1, ChristianKl:, as participants in the proposal of tabular population (P4179). Mahir256 (talk) 02:49, 9 December 2017 (UTC)
We could have a separate property for "tabular ranking", which would store large groups of rankings in data set files on Commons, linked to using the new property. --Yair rand (talk) 04:20, 11 December 2017 (UTC)

Sport ontologyEdit

Hi, I try to create a sports season of a sports club item (now working in 2016–17 Club Joventut Badalona season (Q41991697)), but I did not found any case (full of information, of course) to use as a reference. I see you created a lot of sports season (as 2018–19 Cypriot Second Division (Q52124857) or 1978-79 Cypriot Cup (Q28945). Some questions:

  1. Do you have (or know) any sports season of a sports club item ?
    1. If not, What should by its properties structure, in your experience
  2. For the sport season items, where should the teams results (points, goals, position, etc.) be informed ?
    1. As a qualifiers of the participants teams ?
    2. As a properties in the sports season of a sports club item ?
  3. The sport season items are related with a league or a champioship. However, an sports club can play in several leagues (National league and Champions league, for instance). What should be the ontology in this situation.

Well, any help will be appreciated. Thanks, --Amadalvarez (talk) 21:41, 28 April 2018 (UTC)

@Amadalvarez: hello! Sorry for the delay.

  1. I don't know about sports season of a sports club item.
  2. For the sport season item see 2016–17 Cypriot First Division (Q23756432) (participating team (P1923).
  3. I have not understood the last question. An example?

Xaris333 (talk) 20:05, 30 April 2018 (UTC)

@Xaris333: Thanks so much for your answer. Regarding the 3th question:

Thanks, again. Amadalvarez (talk) 07:13, 1 May 2018 (UTC)

@Xaris333: In addition to your pending answer, I have a [related] new topic to you: Under which property of "sports club (Q847017)" would you list its items of "sports season of a sports club (Q1539532)"?.
Following the example of Cypriot First Division (Q155965) and its sports season (Q27020041), the property should be has part (P527), however, the season summaries are not exactly "a part of" in the case of a club. What about history of topic (P2184) ?. I definitely do not consider sports season of league or competition (P3450) in this case. Probably we should need a new property similar to a exhibition history (P608), a kind of record of results. Thanks, Amadalvarez (talk) 19:33, 3 May 2018 (UTC)

Came here via Wikidata:Project chat#Sport ontology. First of all some queries for items that are instance of sports season of a sports club (Q1539532), of which we have ~58000:

Unfortunately there is no natural candidate property to link to the competition at which the team competed in that season, and no property to link to the club as well, as I see it. Maybe league (P118) can be broadened in scope, but new properties would be really helpful here. Once it is clear how competitions and club/team are going to be linked, everything else can be negotiated. What do both of you think? —MisterSynergy (talk) 17:32, 4 May 2018 (UTC)

Now I just give it a try and proposed:
Comments are welcomed, of course. —MisterSynergy (talk) 06:07, 5 May 2018 (UTC)

@Amadalvarez: do the proposed properties are going to solve the problem? Xaris333 (talk) 07:22, 5 May 2018 (UTC)

Following the topicEdit

Scheme for teams, season by sport, season by team

Excuse me, Xaris333 & @MisterSynergy: to show up again so late. I had to leave the topic of sports. Now, I come back. So,

  1. The two properties season of club or team (P5138) & sports competition competed at (P5249) are OK to solve some of my previous questions.
  2. I draw an entity-relations scheme from the properties descriptions and the present use. See image.
  3. Right now we can't know all the sports season of a sports club (Q1539532) from the team item. In any case, hold the list as a multivalue property (IE P527?) would be too much large for some teams. Some idea ?
  4. In the schema, there are 2 red relations. My opinion is that should be changed:
    1. The participant of (P1344) for a team points to the competitions (national league & international championships). In old teams (Barcelona, Manchester,..), it will have several hundreds entries. In addition, it is used unevenly. For instance, in Newcastle United F.C. (Q18716) it just contains the final match of Cup.
    2. The league (P118) is not a permanent information, because the teams can change each season. It is not a problem if it is used to have the "current information". However, season by season information is in the sports season of league or competition (P3450) of each sports season (Q27020041)
  5. Finally, I draw players as a participant (P710) of team season. It seems redundant with the member of sports team (P54) that this kind of item has. However, the P54 uses to have one entry by team or by national team with the whole period. The idea of P710 in the team season may hold the player results (match played, goals/points,..). What's your opinion about ?.

If you consider moving this discussion to a project space, just tell me where. Thank you so much for your help. Amadalvarez (talk) 17:56, 22 January 2019 (UTC)

Hey Amadalvarez, that’s a pretty neat scheme. Let me directly address your questions:
  • on 3: The trend in Wikidata is not to have too many inverse property pairs; they come with too many complications and inconsistencies, but they barely add any value to the situation. To make it short: you need them if you want to retrieve the list of season items in a Wikipedia article about a club, via a template or module (key problem is that you cannot use SPARQL queries in that case); if this is not a scenario for you, you can go without the inverse relation just as indicated in your scheme. It is pretty easy to retrieve the list with the query service, and the items are properly structured without an inverse relation as well. Thus, if Wikipedia does not matter in this exact situation, do not think about P527.
  • on 4.1: technically same as 3. Here, however, it appears to be more useful to have the inverse relation with P1344 as indicated in the scheme. One could add qualifiers such as ranking (P1352) and some others to the P1344 claim to indicate the final result within that season and retrieve this relatively easily from Wikipedia.
  • on 4.2: I would treat P118 completely independently from the rest. As you indicated it works with qualifiers only anyways, and if you have proper relations to sports season items (and/or team season items), you can infer all the information much more precisely from these relations as the sports season items know their league via P3450. P118 is thus redundant, yet valuable for situations where we do not have sports season items or even team season items.
  • on 5: once again this is technically similar as in 3. Whether P710 is the best pick here is debatable. In the past I considered to propose a "team member" property as a quasi-inverse property to P54, but I am not sure whether it adds enough value and whether there is enough need to have something like that. It would be valuable to retrieve squad members of a team directly from one item in Wikipedia. In cycling they use has part (P527) for that purpose right now (see e.g. Sky 2018 (Q39059584)), but to my opinion this is not very nicely modeled.
There is one thing to mention here which we did not talk about yet: the difference between teams and clubs (example: FC Barcelona (Q3091261), the club vs. FC Barcelona (open age) men's association football team, FC Barcelona (Q7156), one of the club's many teams). Although for FC Barcelona the situation seems pretty okay, there are barely any team items and we often use club items instead, but this might not be the best choice in all situations. In the club item there might be information about different teams of the club. I'm afraid there is little we can do about this right now, but in the future there may be a desire to refine this problem.
If Xaris does not complain, we can stay here for the discussion any maybe move it to another place later if this seems appropriate. There is not much more audience to expect in such a detailed discussion anyways. —MisterSynergy (talk) 20:43, 22 January 2019 (UTC)

Sport uniformEdit

Hi, here again. I see you and @Pasleim: created the first item of sport uniform. Is it the structure to use for this topic ?. I try to transform the template that build the image (football kit) that are almost commons in all WPs and is very difficult to handle this structure.

  • Do you think we have to keep the same logic of image construction created 15 years ago when the limitations were others?
  • The designs of uniforms are becoming more complex and require having their own image (especially for the "body"). If we need to have a specific image for the body, would it not be easier to have it for the entire kit, instead?
  • In addition, under the wears (P3828) of the team item, we'll have directly the image without need 3 new items with a new structure to handle.
  • for plain colors uniform, the images with common colors will be use in all teams with this combination.

I understant this require a discussion and, if you consider this is not the best place, can move it wherever you want. Thanks, Amadalvarez (talk) 05:24, 5 May 2018 (UTC)

  Info There was Wikidata:Property proposal/Home kit (football) (not done) and subsequently Wikidata:Project chat/Archive/2017/12#Football kit. —MisterSynergy (talk) 06:12, 5 May 2018 (UTC)

@Amadalvarez: as MisterSynergy said, there were discussions about sport uniform. Please read them and if you have a different idea, propose something to project chat. Xaris333 (talk) 07:24, 5 May 2018 (UTC)

Sports gapEdit

Hi Xaris333, as you are editing in the field, you might have noticed Wikidata_talk:WikiProject_Sports#A_"How?"-gap_?. In the meantime, I followed-up with Wikidata:Property proposal/Wikipedia glossary entry. In case you are interested.
--- Jura 17:40, 5 May 2018 (UTC)

I haven't understood what is going on. :) What the problem is and the solution of it. Xaris333 (talk) 13:56, 15 May 2018 (UTC)

  • I don't think we have many items about the different technical aspects of practicing a sport, such as those described in w:Glossary_of_association_football_terms. We can easily make items for many concepts in Wikidata, but it would be good to have some description of these concepts. The property proposal provides a way to link to the entries in the glossaries. (A few alternatives are discussed, some of the better ones unfortunately can't be implemented, e.g. import the glossary or use sitelinks).
    --- Jura 15:55, 15 May 2018 (UTC)
  • I rsponded to your comment there. Finally, what's your opinion about it? Do you support it or propose an alternate solution? Do you think the use case is one needing addressing?

Help with Greek descriptionsEdit

Hi :) Since you speak Greek, could you have a look at User:Mr. Ibrahem/fix descriptions/el? I think the capitalisation or grammar is wrong for some of them, but nobody has checked them yet. - Nikki (talk) 11:50, 12 November 2018 (UTC)

I have just corrected two capital letters. The other are correct. Xaris333 (talk) 16:32, 12 November 2018 (UTC)

Thanks. :) Are the descriptions in the "old description" column grammatically correct too? I didn't find any results for "στην Παναμάς" in elwiki. - Nikki (talk) 10:34, 15 November 2018 (UTC)

Done. Xaris333 (talk) 14:34, 15 November 2018 (UTC)

Undo your contributions is a list of (P360) and has list (P2354)Edit

unfortunately I had to undo your contributions. The reason can be seen in the Wikidata property example (P1855) given:

has list (P2354) 
is a list of (P360) 

According to your attitude, the claim should read:

is a list of (P360) 

this is unfortunately wrong, because then the items would have to be the president:

@Labant: Ok. Can you also add your examples to properties talk page for others users who may think as I do in the future? Xaris333 (talk) 00:29, 1 January 2019 (UTC)

good idea, see Property talk:P2354#Using inverse constraint (Q21510855) and of cause: ευτυχισμένο το νέο έτος
