James, It looks like a lot of that phabricator issue was around Taxons ? For the Poodle to show a class of Mammal...
Seems like many of these could be answered if someone responded to https://www.wikidata.org/wiki/User:Danyaljj on their last question about if an "OR" could be used with linktype with gas:service ... where no one gave an answer to their final question comment here: https://www.wikidata.org/wiki/Wikidata:Request_a_query/Archive/2017/01#Timeout_when_finding_distance_between_two_entities I tried myself to answer that question and find either Parent Taxon OR Subclass of a Poodle, but couldn't seem to pull it off using gas:service and 1 hour of trial and error in many forms, even duplicating the program twice ... http://tinyurl.com/yb7wfpwh #defaultView:Graph PREFIX gas: <http://www.bigdata.com/rdf/gas#> SELECT ?item ?itemLabel WHERE { SERVICE gas:service { gas:program gas:gasClass "com.bigdata.rdf.graph.analytics.SSSP" ; gas:in wd:Q38904 ; gas:traversalDirection "Forward" ; gas:out ?item ; gas:out1 ?depth ; gas:maxIterations 10 ; gas:linkType wdt:P279 . } SERVICE gas:service { gas:program gas:gasClass "com.bigdata.rdf.graph.analytics.SSSP" ; gas:in wd:Q38904 ; gas:traversalDirection "Forward" ; gas:out ?item ; gas:out1 ?depth ; gas:maxIterations 10 ; gas:linkType wdt:P171 . } SERVICE wikibase:label {bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" } } On Thu, Sep 27, 2018 at 5:24 PM Stas Malyshev <smalys...@wikimedia.org> wrote: > Hi! > > > Apparently the Wikidata hierarchies were simply too complicated, too > > unpredictable, and too arbitrary and inconsistent in their design across > > different subject areas to be readily assimilated (before one even > > starts on the density of bugs and glitches that then undermine them). > > The main problem is that there is no standard way (or even defined small > number of ways) to get the hierarchy that is relevant for "depicts" from > current Wikidata data.
