What is the protocol to go forward on this? Should we hold a RFC on-wiki to let people choose among the possible solutions above?

We have this problem in https://dissem.in/ . This project is set up on Translatewiki, the code is hosted on GitHub and uses Travis for CI. We use Django's localization system which is based on gettext. We compile messages in the CI to check that they are valid. Sometimes translators add incorrect translations
(such as translations not reusing the same variables as the msgid, or in a different format). This breaks our build as any incorrect translation will stop the entire compilation process. It is not clear if and how it would be possible to configure the translation compilation process to ignore invalid messages.

Any help with finishing the migration is welcome of course, I am currently busy with dissemin but I will try to come back to this at some point.

@Samwalton9 yes that is due to me starting the migration… and not completing it yet!

I have updated the Wikibase data model docs, which incorrectly mentioned precisions of hours, minutes and seconds. I assume that they were there because they were part of an earlier design?

Useful solution from Nikki: add in your common.css:

I have pinged a few interface admins on wiki to enable this.

Oh can they? Sorry I had no idea! Thanks, I will try to enable it myself.

I currently use my own custom hacky script to create properties, but having something stable and usable by anyone would be highly beneficial.

@Lucas_Werkmeister_WMDE thank you very much for that!

I have taken the liberty to remove "Cloud Services" as a subscriber to this ticket as I do not think every toollabs user wants to receive notifications about this.

As explained in T164152 I am happy to mentor anyone for this.

@Daniel_Mietchen regarding https://twitter.com/EvoMRI/status/1055785761574813696 (I do not read Twitter notifications - but happily interact on open platforms such as Mastodon):

The search interface can also be used for that thanks to the haswbstatement command. That only gets you one id per query, so it might not be suited for all tools. I don't know if the lag is lower in this interface.
Retrieving items by identifiers is quite crucial in many tools so it would be useful to have a solid interface for that instead of relying on SPARQL (which feels indeed like using a sledgehammer to crack a nut).

@Gehel my service has been quite unstable for some time, but I haven't found the time yet to find out exactly where the problem is coming from - it could be SPARQL, the Wikidata API, redis or the webservice itself. I will add a few more metrics to understand what is going on and report back here.

@Criscod yes that would be a great idea.

Thanks for the ping Lydia! On the top of my mind, the only uses of SPARQL in the tools I maintain are in the openrefine-wikidata interface:

• queries to retrieve the list of subclasses of a given class - lag is not critical at all for this as the ontology is assumed to be stable. (These results are cached on my side for 24 hours, for any root class.)
• queries to retrieve items by external identifiers or sitelinks - lag can be more of an issue for this but I would not consider it critical. (These results are not cached.)

What matters much more for this tool is getting quick results and as little downtime as possible - lag is not really a concern.

Just to let you know that the problem with the ".0" will be solved in the next version of OpenRefine.
In the meantime, you can solve the issue by transforming your column with the following expression: value.toString().replace(".0",""). Hope it helps!

Woooohooooo!!!!

So I had the opportunity to annoy a lot of people by shouting OpenRefine repeatedly in their ears over the past 48 hours.

Awesome! \o/ Actually OpenRefine could potentially help you already at that stage to do the matching - let me know if you want a quick demo :)

I would be happy to help I have a tshirt with an OpenRefine logo (the blue diamond)

I have left some ideas here:

I will be available to help with OpenRefine. It is exactly designed for this workflow indeed so I hope it will be a match :)
For reconciliation help, have you seen this page?
https://github.com/OpenRefine/OpenRefine/wiki/Reconciliation

I would be interested in helping with this - I can guide you through the uploading process with OpenRefine.
If you want to prepare for this, I feel free to download OpenRefine have a look at tutorials, like these:

• https://www.wikidata.org/wiki/Wikidata:Tools/OpenRefine/Editing/Tutorials/Basic_editing
• https://www.wikidata.org/wiki/Wikidata:Tools/OpenRefine/Editing/Tutorials/Video

The videos at http://openrefine.org/ are also useful to get an idea of what OpenRefine does (with no reference to Wikidata).

Some of the OpenRefine edits were not tagged during development but all edits done with a released version should be. Some of the OpenRefine batches are uploaded via QuickStatements, in which case they are tagged as such. (The main benefits of using QS with OpenRefine is to run batches in the background or to have a statement matching rules when updating existing claims).

Sure, happy to help any time! (Online or at the Wiki TechStorm)

I think this ticket can be closed given that we cannot figure out what it is supposed to be about.

I was thinking of the opposite: consider the violations related to the revision R of the item I to be the violations of the statements of I with respect to the state of Wikidata just before R+1 was saved.

@Lydia_Pintscher yes indeed! For instance the aggregation at batch-level would probably not be meaningful for inverse constraints (unless there is a way to detect all the violations added and solved by an edit, not just on the item where the edit was made). But isn't this a problem that you have anyway, even when storing only the latest violations? For instance, if I add a "subclass of (P279)" statement between two items, don't you need to recompute type violations for all items which are instances of some transitive subclass of the new subclass? I am not sure how this invalidation is done at the moment.

@Lydia_Pintscher personally here is what I would concretely implement in the EditGroups tool. For each edit that is part of an edit group:

• fetch the constraints violations before and after the edit (this fetching would happen as the edit is retrieved, so in near real-time)
• compute the difference of constraints violations of each type (for instance, 1 new "value type constraint" violation and 2 less "statement required constraint" violation)
• aggregate these statistics at a batch level and expose them in batch views (for instance, this batch added 342 new "value type constraint" violations and solved 764 "statement required constraint" violations)

Together with the number of reverted edits in a batch (which the tool already aggregates), this could potentially make it easier to spot problematic batches.

This ticket is fantastic news.

@martin.monperrus see my first comment in this thread.

@martin.monperrus Let me emphasize that this is a significant change that should get community approval first. There has already been a lot of discussion about similar changes to the DOI template on the English Wikipedia and there is clearly a consensus against this IMHO.

@aborrero thanks for the ping. I do not recognize the shape of the queries as coming from this tool though. The openrefine-wikidata tool should do relatively few SPARQL queries, whose results are cached in redis. How did you determine that this tool is the source of the problem?

@Lydia_Pintscher @Ladsgroup any idea how I could be notified of any new automatic edit summaries, such as the wbeditentity-create-item that this change introduced? For any such summary, I need to add it to EditGroups, especially if the new auto summary replaces a highly-used existing one, as in this case. Otherwise, this breaks the tagging of batches.

I think reworking this implementation would be very welcome because at the moment it is not pretty, to say it politely.
But I am not convinced by the alternative either. Why would Reference inherit from BaseClaim? A reference is not a claim. What would the getSnakType method mean when called on a Reference?

It might be worth giving the bot author some control over this feature:

• there should be some opt-in / opt-out mechanism
• there should be some control over what constitutes a batch. Some users might want to create multiple logical batches during the same run of a bot, or share the same batch id across consecutive runs of the same python script (for instance if it is called by a bash script…

Etalab (who runs the open data portal of the French government) have released a statement (in French) concerning the attribution requirement of their "licence ouverte", confirming that it only applies to the first re-user.

@Chicocvenancio I agree with Yury - it makes it significantly harder to deploy Django projects.

This would be very useful for T197588. It would make a lot of sense for Wikibase Quality Constraints in particular.

One other approach to this problem would be to consider that these manifest files are not expected to be necessarily hosted by the Wikibase instance itself - these configuration files could be user-contributed and hosted anywhere (or derived automatically from the Wikibase Registry). The downside is that this requires more work from the community (users need to maintain these manifest files themselves) but it could be necessary if we want to include things like URLs of external tools like QuickStatements.

A sample of what such a manifest could look like is here:
https://gist.github.com/despens/d6ae4110c4e97944ddba29f23d78899f
It could be served at a predictable location for each wikibase instance - such as, for instance,
https://www.wikidata.org/manifest-v0.1.json
or something similar

Just noting that this prevents us from adding examples on lexeme-related properties, such as https://www.wikidata.org/wiki/Property:P5244.

Thanks for adding me in the loop! @RazShuty, do you mean any of this?

• migrate the existing reconciliation service (https://tools.wmflabs.org/openrefine-wikidata/) to work on any Wikibase install
• create a Wikibase extension that already provides a reconciliation API natively, without having to create a wrapper like I did

*anything else?

I have observed this bug multiple times now (also using Firefox).

@Spinster @DarTar That's in 20 minutes in Sala de Projectes! QC/0011

After discussion with @Tpt, for now we are just going to change Wikidata-Toolkit's behaviour to use 0 in the After parameter as well… but that's just because it's really hard to shift the default now.

Oh I meant 10:30, fixing that now

@bcampbell that would be nice! but only if it's not too much effort :)

As a lower hanging fruit, we can also "run OAbot on Wikidata", which would basically mean importing the ids to publication items. @Tpt and I started making a distributed game for that but I think a lot of these could be fully automated. That's a good hackathon-style project if anybody is interested.

When running software on localhost, the client needs to have OAuth consumer credentials, which are supposed to be private. If I apply for an OAuth consumer for OpenRefine, I cannot put the credentials in OpenRefine's source code, because it would allow anyone to reuse them for any other application. So every user would need to go through the OAuth registration themselves (and then OAuth login).

Note to self: for this we would need to rethink Wikidata authentication in OpenRefine, migrating it to OAuth. This would include adding OAuth support in Wikidata-Toolkit. This has not been done yet because OAuth is not suited for open source software that is run directly by the user on their own machine.

As soon as this is supported by the Wikibase API, then it makes sense to build support for this directly in Wikidata-Toolkit. This is something that would be massively useful for many people.

I won't work on this for the next 2 weeks, the floor is yours!

@Nemo_bis that's probably because the edits were cached and generated by an earlier version
