Welcome to Wikidata, SM5POR!

Wikidata is a free knowledge base that you can edit! It can be read and edited by humans and machines alike and you can go to any item page now and add to this ever-growing database!

Need some help getting started? Here are some pages you can familiarize yourself with:

  • Introduction – An introduction to the project.
  • Wikidata tours – Interactive tutorials to show you how Wikidata works.
  • Community portal – The portal for community members.
  • User options – including the 'Babel' extension, to set your language preferences.
  • Contents – The main help page for editing and using the site.
  • Project chat – Discussions about the project.
  • Tools – A collection of user-developed tools to allow for easier completion of some tasks.

Please remember to sign your messages on talk pages by typing four tildes (~~~~); this will automatically insert your username and the date.

If you have any questions, don't hesitate to ask on Project chat. If you want to try out editing, you can use the sandbox to try. Once again, welcome, and I hope you quickly feel comfortable here, and become an active editor for Wikidata.

Best regards! ArthurPSmith (talk) 18:19, 8 September 2020 (UTC)

What does this constraint mean?Edit

As I understand allowed-entity-types constraint (Q52004125), the qualifier value should be an entity type that the property may be used on: item, property, lexeme, etc. But as main value (Q54828448) isn't an entity type. What is this constraint supposed to do? Thanks, Swpb (talk) 14:42, 7 March 2022 (UTC)

@Swpb: Oops, thanks for notifying me! I must have slept while editing... I meant to say "Wikibase item", but I just undid that change now, and will defer setting the correct values until I know which ones apply. Property seems unlikely, but perhaps some Lexeme, Form or Sense might use it? --SM5POR (talk) 19:40, 8 March 2022 (UTC)
Ah, ok! I think Wikibase item would be the only acceptable entity type for criterion used (P1013). Swpb (talk) 19:45, 8 March 2022 (UTC)
@Swpb: The reason I'm considering also the lexeme/form/sense domain is that criterion used (P1013) has as qualifier (Q54828449) as its (only) permitted property scope. There are several properties that can be used with lexemes just as well as with regular items, and criterion used (P1013) is such a generic qualifier that it might well be used with some of those, such as statistical or demographic ones, say a map showing where a particular word is commonly used or whatever.
At the very least, I should investigate current usage of criterion used (P1013) before interfering with possibly quite reasonable use. If there is currently no conflicting use, I may still want to leave my considerations above in a note just in case someone may try it in the future.
The lexeme domain is still very much under development, and I have a number of ideas that I'd like to discuss within the lexicographic project, such as moving certain properties (say, female form of label (P2521) or other cases requiring massive use of language of work or name (P407) as qualifiers) out of the item domain and into the lexeme/sense domain only. --SM5POR (talk) 09:24, 9 March 2022 (UTC)

You did something to this property that is messing it up on Commons. It's meant to be used as part of the "depicts", as you can tell because P462 is an instance of Wikidata property used as "depicts" (P180) qualifier on Commons (Q70564278), but now it says it can't be used because of constraints not allowing it. I'll assume you were trying to do something constructive, so a remedy by you is better than a revert by me. Senator2029 13:35, 8 March 2022 (UTC)

@Senator2029: Thank you for alerting me to the problem. I was unaware of the depicts (P180) relationship; could you please point to an example of such usage? I have undone my changes and will not reinstate them until I understand their implications. --SM5POR (talk) 19:44, 8 March 2022 (UTC)
Thank you. Also, I had the opportunity to browse through your contributions and user page. You do good work—most of it complicated—but necessary for Wikidata to be reliable as a repository of facts. Laying the groundwork for other editors to follow will be appreciated by all who use Wikidata, now and in the future. Senator2029 20:57, 15 March 2022 (UTC)
@Senator2029: Thank you, it's good to get confirmation that I'm on the right track. But during the two years since I first learned about Wikidata, I have become overwhelmed by the magnitude of the effort. I have plenty of ideas to explore, but I'm acting alone, cooperating with others on a rare few issues only, lacking the sustained teamwork that might make the job easier. Do you have any suggestions for how to find or create a team? The WikiProjects I have joined don't seem to function as teams. --SM5POR (talk) 05:46, 16 March 2022 (UTC)

Hi Sm5por,

TomTom POI files are called .asc or .ov2. The itenary is always called .itn. Wonne-Kietz Connewitz (talk) 19:08, 11 December 2022 (UTC)

@Wonne-Kietz Connewitz: Hi, thank you for contributing! I had to go back in my history log to see what I had been doing with that item... I now recall fixing some problem with the file format family (Q26085352) properties that led me to go through the GPSBabel (Q1486544) file formats. The filename extensions you mention could be added using file extension (P1195), but that property also recommends adding the corresponding MIME type (P1163) codes. You don't happen to know what those type codes are? SM5POR (talk) 21:22, 11 December 2022 (UTC)



In a message on WD:LD, you made a digression and said « maybe 50,000 instances of term (Q1969448) » and then talking about moving them to the Lexeme namespace. Out of curiosity, I did a SPARQL query: https://w.wiki/6DC3 but only found 1911 results, almost none could be deleted as item : only 149 are not linked to a wikimedia page: https://w.wiki/6DC4 so we could copy them but not moving them.

Is there something I misunderstand? If we could move some data to Lexemes, I would be glad to help.

Cheers, VIGNERON (talk) 20:04, 10 January 2023 (UTC)

@VIGNERON: I may have misremembered some of my statistics, but try wdt:P31/wdt:P279* and you'll get something like 20,000 hits, and lots more if you expand the class from term (Q1969448) to word or phrase (Q115372263) (I think you should use SELECT DISTINCT and filter away lexemes to avoid duplicates and only get items from Q-space).
I'm aware of the problem with other Wikimedia pages currently requiring Q-items in Wikidata, but I have a suggestion for that too (it will require revising WMF/Wikidata standard policy and probably some phabricator tickets): Allow redirection from Q-space to L-space, or even link Wikipedia etc directly to L-space.
It's obviously not something we can decide alone, but I believe this is a means for WMF to move forward in the long run; every word of every language simply doesn't belong in Q-space in addition to having a lexeme in L-space. SM5POR (talk) 20:57, 10 January 2023 (UTC)
