Hi Jeremy and Max, 1. Does the wikidata design not entail template/parser calls which can be inspected by editing the page and seeing *all* data passed for storage to/by the wikidata engine? Are you saying that wikidata's data entry interface is to be the only method to be available to *humanly* see what data is being stored? 2. About "page type" - where is this discussed? I look in the RDF info for Wikidata and all I see is w:Berlin s:Population Berlin:Statement1 . Berlin:Statement1 rdf:type o:Statement . <snip/> I see NO w:Berlin rdf:type some-type-as-asserted-by-jeremy-and-max. Would you please provide a link or pointer to documentation about these "types"?

Thanks for the link. So Max's original question was whether a "content-type'd page" containing (json-? xml-? rdf-?) -encoded data, can have markup conforming to schema.org ontologies? Seems that if xml/rdf is a "supported content type" then an opening does exist for such to be implemented however only by individual wikipedia sites; because it seems clear that wikidata will not process such rdf/xml in order to create wikidata statements that can be displayed within infoboxes. It does raise the question of whether wikidata defines a content type for its json markup, that is, json markup that conforms to its SNAKs ontology? Is there a list of the content types somewhere? I looked but could not find one in ContentHandler.php. thanks - john On 14.09.2012 11:00, Jeremy Baron wrote: &lt;jmcclure(a)hypergrove.com&gt; wrote: these "types"? https://www.mediawiki.org/wiki/ContentHandler _______________________________________________ list https://lists.wikimedia.org/mailman/listinfo/wikidata-l

Your response doesn't direct me to a list of content types ("supported formats"). But you know I'd suggest the answer to your question wrt schema.org, is found in the published RDF [1]: w:Berlin s:Population Berlin:Statement1 . Berlin:Statement1 rdf:type o:Statement . Note that we introduced two new properties, s:Population (s: like statement) and v:Population (v: like value) instead of the original p:Population property (mind the namespaces). The original property, in the p: namespace, is a datatype property that connects items directly with an integer value (i.e. the domain is item). The s: property, on the other hand, is an object property connecting the item with the statement about it." [1] [1] https://meta.wikimedia.org/wiki/Wikidata/Development/RDF#Statements_with_qu… The problem is this: "s:Population" is not published that I can find. So is the question will "s:Population" be mapped to some schema.org/Population rdf:Property definition, if there were such a thing defined at schema.org? But looking at schema.org, "population" is usually defined as a p:Population kind-of-thing, not an s:Population kind-of-thing. In wikidata, p:Population is an rdf:Datatype, s:Population an rdf:Property. Schema.org's population is a datatype, not a class in an ontology, so they're not fitting together. But as I've said, it's a problem that s:Population is not defined. Is "s:Population" not closer to a collection, a bag, that has restricted content that is, a "bag of statements" (see quotation above), than it is to a functional definition of "Population" as something more like a "group of living individuals", "alive" as per some specified context? Where does THIS concept of "population" fit with <rdf:Property rdf:about=wikidata/s:Population/> ? Hard to avoid that s:Population basically is just short-hand for "Population Statements". Using shorthand certainly has precedence, being that q:Qualifier is short-hand for a category, an owl:Class, and thus "q:Draft" is (very acceptable) short-hand for "Draft Things"... So we need a crisp definition of s:Population please!

The content *model* Wikidata uses is the one with Statements and Snaks, described by the Wikidata data model spec. The content *format* used for serialization is JSON. The mapping from the internal model to JSON is currently not formally described, the internal JSON serialization is an implementation detail. The external JSON serialization as used by the web API is similar to, but not necessarily the same as the serialization used to represent Wikidata items internally. The JSON form used in the API is documented to some extend on the Extension:Wikibase page on mediawiki.org, but it's still subject to change. -- daniel -- Daniel Kinzler, Softwarearchitekt Wikimedia Deutschland e.V. | Eisenacher Straße 2 | 10777 Berlin http://wikimedia.de | Tel.
