[Wikidata-l] Changes to the API for Wikidata
by John Erling Blad 07 Sep '12

07 Sep '12

Please note that this is a breaking change for bots! It is decided that the module wbsetitem will change from the present "short form" in the json structure to a "long form". Exactly how the long form will be is still a bit open, but it will be closer to the json output format. The changes also makes it possible to use a key-less format as the language and site id will be available inside the long form. The following short form will be WRONG in the future { "labels":{ "de":"Foo", "en":"Bar" } } This long form will be RIGHT in the future { "labels":{ "de":{"value":"Foo","language":"de"}, "en":{"value":"Bar","language":"en"} } } And also this will be RIGHT { "labels":[ {"value":"Foo","language":"de"}, {"value":"Bar","language":"en"} ] } New modules may use a long form if they support json input, but that for the future. In some cases it seems necessary to add flags for what to do with individual fields, but perhaps we can avoid it. (Typically for adding/removing aliases, but it could also be necessary for other fields.) There are also a new "clear" URL argument that will clear the content of an item and make it possible to rebuild it from scratch. Default behavior is NOT to clear the content, but to incrementally build on the existing item. Also note that use of [no]usekeys in the URL is not supported anymore.

[Wikidata-l] next Wikidata office hours
by Lydia Pintscher 06 Sep '12

06 Sep '12

Heya folks :) The next Wikidata office hours are coming up. You're invited to come and ask your questions - technical or non-technical. Some of the things to talk about are for example the things listed in the "This needs your input" box on http://meta.wikimedia.org/wiki/Wikidata but other topics are welcome as well. Unlike previous Wikidata office hours we'll be doing this one in #wikimedia-office. English: 5 Sept. at 8:00 UTC (http://www.timeanddate.com/worldclock/fixedtime.html?hour=08&min=00&sec=0&d…) German: 6. Sept. at 16:00 UTC (http://www.timeanddate.com/worldclock/fixedtime.html?hour=16&min=00&sec=0&d…) Hope to see many of you there.

Re: [Wikidata-l] Wikidata, ISO and chembox

Hello John McClure thanks a lot for the explanations, unfortunately I have some open questions left. You wrote: "Why is the topic map standard at http://www.topicmaps.org/standards/ [8] an unofficial topic map standard?" Links can be found to working technical committee reports, which are generally re-titled as "standards" once voted and accepted by ISO. These TC reports vary little from what is published by the ISO community as a "standard". So this is a standard by the ISO and thus I think it is at least SOME standard and so one probably shouldnt call it non-standard even if one is not happy with this standard, no? "ISO/IEC 19788-1:2011 is information-technology-neutral" means that information elements defined by the standard for learning resources can be represented using a concrete implementation syntax such as provided by the RDF or by Topic Maps or by SMW syntax or by JSON or by a variety of others. For instance, a data element defined by 19788 might be "Learning Resource" which has an attribute called "Minimum Education Level". OK I think I understand now. You mean ISO/IEC 19788-1:2011 is probably a version of ISO/IEC 19788 since 2011 is probably the year 2011 and not a different (newer) kind of specification. Information-technology-neutral means that it is a specification that is neutral with regard to the specific infromation-technological implementation, but not neutral with regard to the aspect of information-technology per se. Where do you have this information from? You had just written that "To my knowledge ISO has not published, nor is intending to publish, instances of topic maps representing the content of their numerous publications, using either their (ISO's) standard for Topic Maps (ISO/IEC 13250), or any other ISO or non-ISO standard. Forgive me if I ever gave that impression." but using a concrete syntax which "can be represented using a concrete implementation syntax such as provided by the RDF or by Topic Maps or by SMW syntax or by JSON or by a variety of others." is ALMOST as good as directly publishing a machine readable standard! and as it seems by looking at this secret paper: N2448 - `summary of voting on ISOIEC NP 18343, Learning environment profile for automated contents. at http://isotc.iso.org/livelink/livelink/open/jtc1sc36 it seems that they may have now plans to concretely publish a standard. I was not talking about the rdf ontology like in the XML serialization <rdf:RDF but about the rdf graph data model this: <rdf:RDF xmlns:iso="http://iso.org/19788/" xmlns:dc="dublin core"> <iso:LearningResource rdf:about="LR12345"> <dc:title>Lithium</dc:title> <iso:minEducLevel>12th grade</iso:minEducLevel> </iso:LearningResource> </rdf:RDF> is already a serialized format which you would probably (I am not overly familiar with XML) phrase in the RDF graph model as (Lithium(dc:title) ----minEducLevel(iso:minEducLevel)--> 12th grade(literal))-----Learningresource(iso:LearningResource) ---> LR12345 (rdf:about, literal) (Lithium(dc:title) ----minEducLevel(iso:minEducLevel)--> 12th grade(literal))-----rdfXMLsource(rdf:xmlns)---->(iso="http://iso.org/19788/") (Lithium(dc:title) ----minEducLevel(iso:minEducLevel)--> 12th grade(literal))-----rdfXMLsource(rdf:xmlns)---->(dc=dublincore) where I put the "URI" (which is here given by the link to the respective ontologies) or the term literal in brackets. Do you agree? I may then look at your topic map formulation.

I was talking about the ISO contents. I also wrote a reply to Luca Martinelli, but apparently this got lost in transmission/moderation.??? (i am not an official wikidata list member what ever the criteria for being such a member are) I just try to warn wikidata people that is I GOT THE IMPRESSION THAT THE ISO WANTS TO PUBLISH THEIR OWN MACHINE READABLE STANDARD AND THAT CONFLICTS WITH WIKIDATA MAY ARISE IN THAT PROCESS WHICH COULD EG RESULT IN LAW SUITS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! (IN WHICH THE ISO WILL CLEARLY HAVE A FAR BETTER POSITION OR IN OTHER WORDS WIKIDATA WOULD BE SQUASHED IN SUCH A PROCESS) SO WIKIDATA SHOULD TRY TO CLEAR THE CONFLICTS OR AT LEAST GET AN OVERVIEW ABOUT WHAT COULD HAPPEN AND EVENTUALLY LOOK FOR STRONG SUPPORTERS. I DONT KNOW HOWEVER HOW MUCH THIS IS POSSIBLE AT ALL. Nadja

Mr. Denny Vandrecic, many thanks for your detailed answer. Let me try to explain the open questions "I am not a lawyer, but I want to point out that there is a distinction between Copyright and other IP protection. Whereas a text about the classification of hammers may (and usually is) copyrighted, the mere fact that a hammer is a tool can not be copyrighted." -One would hope so, but there are so many strange things which are under IP protection that I wouldnt count on that and let a lawyer have a look on that. "Also, we need to make a distinction between the IP for the data model of Wikidata and the content of Wikidata." -John McClure was talking about the underlying basic data model and I just replied to his ISO topic map comment. I havent looked much at your Wikidata data model sofar. If you export RDF and ISO topic maps then this discussion is for moment rather not important. -Regarding the discussion about the ISO - I was talking about their content classification scheme. That is if the wikidata classification (like a hammer is a tool etc.) is built up (or in other words the wikidata ontology) then one may accidentally or on purpose use the ISO classifications. And it would at least make sense to refer to them since a lot of industrial applications use ISO standards. "Just as the MediaWiki developers do not decide on the content of Wikipedia, the Wikidata developers do not decide on the content of Wikidata. I hope the distinction makes sense." - I understand this however at some point it seems the wikidata project has to think about these issues moreover eventually your data model could be influenced by ISO choices, but as said I havent looked into that yet

Forgive me if I ever gave that impression. You provided a nice link to unofficial topic map standards, thank you. Here's others: http://www.garshol.priv.no/download/tmlinks.html." thanks for the link. Why is the topic map standard at http://www.topicmaps.org/standards/ an unofficial topic map standard? They talk about that it is ISO 13250 standard. You had drawn my attention to the ISO, thanks for that however the impression that they might have some standards is from their website: http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnu… where they write amongst others: "The primary purpose of ISO/IEC 19788 is to specify metadata elements and their attributes for the description of learning resources. This includes the rules governing the identification of data elements and the specification of their attributes." since this thing costs 162 CHF i can't check what those guys are really doing there, however it would be strange to define metadata which is not for automated processing. In particular they write a little later: "ISO/IEC 19788-1:2011 is information-technology-neutral and defines a set of common approaches, i.e. methodologies and constructs, which apply to the development of the subsequent parts of ISO/IEC 19788." would they write this if ISO/IEC 19788 was information-technology-neutral as well? moreover there exists also a N2448 Summary of voting on ISOIEC NP 18343, Learning environment profile for automated contents which is password protected at the webpage: http://isotc.iso.org/livelink/livelink/open/jtc1sc36 but where the word AUTOMATED appears explicitly. but of course it would be nicer to have someone who knows explicitly what exactly they are having in mind there at ISO.

Luca Martinelli wrote: If I got it right, someone expressed his/her doubts about using ISO standards in classifying data on Wikidata because of [this point may be challenged, but this is what I understood] potential ISO copyright issues. Now, the points are: a) Is my guess correct? If no, what is the point this discussion is about? b) Is there anyone who could answer this doubt, whatever it is? your guess is correct. I was having doubts. As I pointed out here earlier in this thread it seems that the ISO plans to publish some (automated) metadata. If they are going to recast their database into a giant ontology then they probably want to sell this, since selling the information of standards is part of their business model. If wikidata would built up a similar ontology this business model wouldnt work anymore and so my fear is that there could already be an Armada of lawyers waiting to jump in.
