Linked Data Fragments endpoint returns IllegalStateException
by Maciej Gawinecki 31 Mar '21

31 Mar '21

Hi, I am trying to get alternative names of given names in WikiData with the following simple query: PREFIX ps: <http://www.wikidata.org/prop/direct/> PREFIX wd: <http://www.wikidata.org/entity/> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> CONSTRUCT {?s rdfs:label ?o} WHERE { ?s ps:P31 wd:Q202444. ?s rdfs:label ?o} LIMIT 1000 Initially, the query was much more complex, but I was getting time-outs on the public WikiData SPARQL endpoint. I decided to use Linked Data Fragments to offload some filtering from the server to the client. comunica-sparql "https://query.wikidata.org/bigdata/ldf" -f query > given_names.n3 (where "query" is a file with the SPARQL query shown above). Unfortunately, the client tries to get output from the 3rd page, I am getting the following error: Could not retrieve https://query.wikidata.org/bigdata/ldf?subject=http%3A%2F%2Fwww.wikidata.or… (500: unknown error) Following the link in fact returns HTTP 500 error with Error details java.lang.IllegalStateException The link points to the 3rd page. It works if you try to go the second page: https://query.wikidata.org/bigdata/ldf?subject=http%3A%2F%2Fwww.wikidata.or… Is this a bug or a limitation of a service? With kind regards, Maciej Gawinecki

Creating new items in wikibase with a supplied ID
by Erik Paulson 28 Dec '20

28 Dec '20

Hello - The tl;dr version of this post: On a blank Wikibase instance, I want to be able to do: api.php?action=wbeditentity&*new=item&id=Q42*&data={"labels":{"en":{"language":"en","value":"Douglas Adams"}}} I do not want to do this on wikidata.org - I understand why it makes no sense in that context. But I would like to be able to do this on my own Wikibase instance. Beyond the whimsical like ensuring Doug Adams gets to be Q42, the main reason for this is data portability and identifier stability. As more hosted Wikibase providers come online and start offering services, I want to know that I have data portability if I need to change to a different provider. Anyone who queries my Wikibase needs to know the identifiers my Wikibase uses for instances and more importantly for classes, and if I change providers, those identifiers cannot change without breaking those queries. I do not think that MySQL backups are a reliable way to be able to transition between providers. I am not confident that all providers will want to offer a service where they accept a MySQL backup to load into their Wikibase backend, and there are additional challenges moving between Wikibase versions. (Though some may - I programmatically create the contents of my Wikibase so I don't care about edit history, but if one were to care about that history and other things like wikiusers I imagine the MySQL dumps would be the preferred way to migrate) One possible solution is to simply create blank items in a new Wikibase, from 1 to the maximum identifier used in my old wikibase, and then repopulate each item with the claims from my old Wikibase instance. Unfortunately this is not a reliable solution because while Wikibase guarantees that item IDs will not be reused, it does not guarantee that every ID in the sequence will be created, e.g. in rare cases Wikibase may go from Q41 to Q43 and skip/never create Q42. I think Wikibase is awesome, but it is an odd database that does not allow you to set the keys for the data you are managing :) In reading through the Wikibase Repo code, it seems like this scenario was considered though perhaps isn't fully implemented (or has been disabled?). The code in EntitySavingHelper.php looks like there are/were ways to call it by providing an ID while still asking for a new entity, though there is logic earlier in the ModifyEntity code to look for and explicitly reject the case where the API asks for 'new' and also provides an ID, so I'm not sure how this code path would get called. There is also code to ask the entityStores if they 'canCreateWithCustomId', but those all appear to just return 'false'? However, if that logic was skipped in the API handler and a bit of code reworked in ModifyEntity and EntitySavingHelper, along with ensuring that that the next available ID is kept up to date in the wb_id_counters table to always be 1 beyond the maximum ID in use, it looks like it might not be that hard to enable creating entities with specific IDs? So three questions: Would the Wikibase development team ever be open to supporting something like this, behind a flag like $wgWBRepoSettings['allowUserProvidedIds'] that defaulted to false? Are there more complicated implications from allowing a change like this that would need to be considered? I understand why the Wikidata.org repo needs this codepath fast and can't allow users to provide IDs for new entities anyway, but are there other reasons this isn't supported beyond "Wikidata doesn't need it?" Is this all moot with the eventual REST API? I see that there's a PUT envisioned, could I use that to directly create an item or property and give it an ID then, or does the ID have to already exist to replace it? Thank you all for your work on Wikibase and have a nice end of 2020! Thanks, -Erik

Lexeme's Transliteration documentation, let's improve! ; -)
by Thad Guidry 16 Dec '20

16 Dec '20

Hi Community! I've read over the last 2 weeks various previous comments, questions, concerns about how to best handle Transliterations which are different from Translations (consensus is to use Senses for Translations) But for Transliterations, it seems that a general consensus is around using Forms (as the Lemon model does) to handle this and also make querying easier I guess. I'd like to improve the documentation on the wiki pages for Lexicographical Data Model with a general page on Transliteration concerns. As I understand it, there are already Language specific pages to deal with Transliteration and Translation concerns (such as this one for Bengali <https://www.wikidata.org/wiki/Wikidata:Lexicographical_data/Documentation/L…> ) My proposal to all here listening is to have a new sub page called https://www.wikidata.org/wiki/Wikidata:Lexicographical_data/Documentation/T… to handle the general documentation effort for that, and where it would have only a few practical examples to help new users with general Forms entry of Transliterations, and taking example from this section of the Lemon model cookbook on Phonetics: https://lemon-model.net/lemon-cookbook.pdf#subsubsection.2.1.2 The proposed Transliteration page would also have a link from the main doc page in the Forms section (see my placeholder in the Form section now <https://www.wikidata.org/wiki/Wikidata:Lexicographical_data/Documentation#F…>) Thoughts?
