Wir sollten mal darüber nachdenken, ob das so sein muss. Wäre doch prima, wenn sich das kombinieren ließe... Und selbst wenn nicht: Per Klick Fakten aus den Quality-Daten zu importieren sollte nicht schwer zu machen sein. Auch ein schöndes Projekt für 'nen Studie... -- Daniel Kinzler Senior Software Developer Wikimedia Deutschland Gesellschaft zur Förderung Freien Wissens e.V.

API JSON format for warnings
by Markus Krötzsch 09 Sep '15

09 Sep '15

Hi, I am wondering how errors and warnings are reported through the API, and which errors and warnings are possible. There is some documentation on Wikidata errors [1], but I could not find documentation on how the warning messages are communicated in JSON. I have seen structures like this: { "warnings" : {"wbeditentity": {"messages": [{"name":"wikibase-self-conflict-patched", "parameters":[], "html": { "*":"Your edit was patched into the latest version, overriding some of your own intermediate changes."} }] } } } I don't know how to provoke more warnings, or multiple warnings in one request, so I found it hard to guess how this pattern generalises. Some questions: * What is the purpose of the map with the "*" key? Which other keys but "*" could this map have? * The key "wbeditentity" points to a list. Is this supposed to encode multiple warnings of this type? * I guess the "name" is a message name, and "parameters" are message "arguments" (as they are called in action="query") for the message? * Is this the JSON pattern used in all warnings or can there also be other responses from wbeditentity? * Is this the JSON pattern used for warnings in all Wikibase actions or can there also be other responses from other actions? * Is there a list of relevant warning codes anywhere? * Is there a list of relevant error codes anywhere? The docs in [1] point to paraminfo (e.g., http://www.wikidata.org/w/api.php?action=paraminfo&modules=wbeditentity) but there are no errors mentioned there. Thanks, Markus [1] https://www.mediawiki.org/wiki/Wikibase/API#Errors

How fast should I edit? (as user/as bot)
by Markus Krötzsch 09 Sep '15

09 Sep '15

Hi, Users without a bot flag will quickly receive an error when trying to make too many edits in a row [1]. I noticed that I am getting this even when editing at a rate of 0.5 edits/second. What is permissible there? I would like to use this as a default throttling in WDTK. Moreover, when editing as a bot, this limit does not apply. Is there a recommended edit rate for bots? Of course there is the dispatch statistics, but I guess it is better to avoid pushing this to a high value before stopping. Thanks, Markus [1] "[failed-save] As an anti-spam measure, you are limited from performing this action too many times in a short space of time, and you have exceeded this limit. Please try again in a few minutes." -- Markus Kroetzsch Faculty of Computer Science Technische Universität Dresden +49 351 463 38486 http://korrekt.org/

how is the datetime value with precision of one year stored
by Raul Kern 03 Sep '15

03 Sep '15

I run into this datetime problem in et.wiki, with displaying wikidata population date in city infobox. For example in article https://et.wikipedia.org/wiki/Vilnius the wikidata population date "2014" becomes "30.11.2013". And when I modify the wikidata module to take the precision into account then "2013" is displayed as date. It could be something I'm overlooking in wikidata module https://et.wikipedia.org/wiki/Moodul:WikidataDev or in city infobox template https://et.wikipedia.org/wiki/Mall:Linn. No problems with population dates were the precision is one day. -- Raul

how is the datetime value with precision of one year stored
by Raul Kern 01 Sep '15

01 Sep '15

Hi, how is the datetime value with precision of one year stored? For example for birt date in https://www.wikidata.org/wiki/Q299687 fine grain value for "1700" is "1.01.1700" But for population date field in https://www.wikidata.org/wiki/Q216 the fine grain value for "2014" is "30.11.2013" Which is kind of unexpected. -- Raul
