\r\n    Maybe even get people to help out?\r\n\r\nUpdate 2016-01-26 - since the original post there have been some improvements at both Wikidata and Schema.org:\r\n\r\n * Wikidata: mappings (exact, super/sub) from properties and (perhaps to a lesser extent in that the notion isn't so built-in) types to schema.org can be expressed within Wikidata.\r\n * Wikidata now has a SPARQL endpoint at https://query.wikidata.org which is the most natural way of retrieving data; other explorations such as JSON dumps below are less important now.\r\n * Schema.org has updated its extension mechanism and is encouraging both hosted and external extensions.\r\n * D3-compatible RDFS JSON-LD is published from schema.org and can be used for visualization; this would also be a good model for getting an overview of Wikidata. See http://bl.ocks.org/danbri/1c121ea8bd2189cf411c for example visualization. \r\n * Various notes towards using Wikidata as an extension language for Schema.org are explored towards the end of this issue, as are SPARQL queries for extracting Wikidata's structure and property metadata for use in mappings.\r\n \r\n\r\n"},"comment":{"url":"https://api.github.com/repos/schemaorg/schemaorg/issues/comments/174311358","html_url":"https://github.com/schemaorg/schemaorg/issues/280#issuecomment-174311358","issue_url":"https://api.github.com/repos/schemaorg/schemaorg/issues/280","id":174311358,"user":{"login":"ppKrauss","id":1651447,"avatar_url":"https://avatars.githubusercontent.com/u/1651447?v=3","gravatar_id":"","url":"https://api.github.com/users/ppKrauss","html_url":"https://github.com/ppKrauss","followers_url":"https://api.github.com/users/ppKrauss/followers","following_url":"https://api.github.com/users/ppKrauss/following{/other_user}","gists_url":"https://api.github.com/users/ppKrauss/gists{/gist_id}","starred_url":"https://api.github.com/users/ppKrauss/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ppKrauss/subscriptions","organizations_url":"https://api.github.com/users/ppKrauss/orgs","repos_url":"https://api.github.com/users/ppKrauss/repos","events_url":"https://api.github.com/users/ppKrauss/events{/privacy}","received_events_url":"https://api.github.com/users/ppKrauss/received_events","type":"User","site_admin":false},"created_at":"2016-01-24T15:54:46Z","updated_at":"2016-01-24T15:54:46Z","body":"Hi @nemobis, thanks, can you express your ideia in a [query at Wikidata](https://query.wikidata.org/)? A query that demonstrate to us that an external concept (ex. SchemaOrg's [author](http://schema.org/author)) is equivalent to a Wikidata item? (Q482980 in this ex.)... The problem is how to define each external concept in a generic SPARQL query.\r\n\r\nAbout *equivalence operator* have two meanings here, in this issue (#280), \r\n\r\n* express the Wikidata links into the  [SchemaOrg formal specification](https://github.com/schemaorg/schemaorg/blob/sdo-deimos/data/schema.rdfa). See [elf-pavlik's  comments](#issuecomment-75584818) (`owl:equivalentClass` or `rdfs:subClassOf` for classes and `owl:equivalentProperty` or `rdfs:subPropertyOf` for properties);\r\n\r\n* express queries in SPARQL, algorithms for the \"concept matching automation\". See [danbri's query](#issuecomment-174094917) (`extequiv` or `extsuper` or `extsub`), and your suggestion of use [P1709](https://www.wikidata.org/wiki/Property:P1709).\r\n\r\nAbout my use of the term \"consensual\", is not about the *equivalence operator*, is about our \"human understanding\" and a community agreement (consensus) about understanding of each one (me, you and any other here discussing). Do you agree with my *concept matching*, at 1-4 listed pairs?\r\n\r\n------\r\nPS: as soon as there are more Wikidata items in the [handmade sample set](https://docs.google.com/spreadsheets/d/1KeTSrVjSHRfVRwSgg6-LN0pu6nVre7cspUrkf_gfMm8/), the greater the difficulty of check or reaching consensus... So, we need to start with good consensus before to close the sample set. An homologated  sample set is fundamental to test and discuss any kind of algorithm here.\r\n"}}
