translation: QS ---> wikibase-edit JSON

[rwst]

QuickStatements commands can be translated to JSON that is fed to the wd ee --batch (or create-entity) commaand by the user. Some commands may need an automated SPARQL query before translation. Still, such a tool would be valuable, if not for the reason that QS needs to be fixed, and no one wants to fix PHP.

could you provide a sample of the QS JSON, with annotation of how it should be interpreted if there is anything non-trivial? (I have not worked with QS much, so I do need some guidance)

It is not JSON but a simple command language made for the purpose, please see https://www.wikidata.org/wiki/Help:QuickStatements#Command_sequence_syntax

This is exactly what I'm looking for! I'm developing a WikiCite (a Wikidata project) plugin for the reference management software Zotero, and I would like to provide a way of creating new Wikidata entities from Zotero items. Right now there is this QuickStatements translator that translates a Zotero item into QuickStatements commands. Having a way to translate these QS commands into wikibase-edit JSON, as suggested in this issue, would be ideal.

This PHP file, from QuickStatements source code, takes care of converting QS commands into MediaWiki API actions. I wonder if it may be useful to create the JS tool proposed.

I started experimenting in a separate repo https://github.com/maxlath/quickstatements-to-wikibase-edit :

• how practical would this approach be for your respective use-cases?
• note the missing features section: those are due to those features being currently missing in wikibase-edit

Amazing! This is exactly what I was looking for. I installed it through npm and tried it with a simple set of QS commands returned by Zotero's QuickStatements export translator:

CREATE
LAST	P31	Q13442814
LAST	Len	\"Test article\"
LAST	Den	\"journal article\"
LAST	P1476	en:\"Test article\"
LAST	P407	Q1860

However, convert.js is failing at line 34 with edit.claims is undefined. I guess this is because you are still experimenting with it.

I couldn't debug it because I may not have time to implement this new feature immediately, but I have already posted an issue in my plugin's repository to keep track of this and use it as soon as possible.

Thanks!!

@diegodlh could you provide a sample of the input that fails to be converted?

I finally found the time to look into this more closely today. I submitted a PR that seems to fix it.

With this fix, and other time-value-related fixes, I'm using this package in Cita and it seems to work like a charm to convert QuickStatements commands for basic publications (journal articles, etc) into a JSON that wikibase-edit can understand.

Thank you!!
