Motivation

We seem to have several properties for various aspects brought to us by @Toni 001:, but lacking one for this key element of Wolfram. Please help complete the proposal/add more samples (Add your motivation for this property here.) --- Jura 06:46, 19 October 2019 (UTC)

@GZWDer: who seem to have done some mapping for these. --- Jura 07:32, 19 October 2019 (UTC)

Compare WL and Wikidata classes

There is a correspondence between the result of EntityList[EntityClass["Element", All]] in the WL and the following SPARQL query:

select * where {
  ?item wdt:P31 wd:Q11344 . # chemical element
  ?item rdfs:label ?itemLabel . filter (lang(?itemLabel) = "en")
}

Try it!

This property will allow users to map between the two types of query to, say, compare their members. Toni 001 (talk) 09:34, 19 October 2019 (UTC)

@Jura1, Toni 001: I have made a list of all entities of all entity type that is emuneratable (some entity types, like IP addresses, are not) and have no more than 500000 entries. only a part of the list are imported to Mix'n'Match. There're 250 such types as of 2018-07-17.--GZWDer (talk) 10:38, 19 October 2019 (UTC)

EntityValue[] gives an incomplete list of entity types. There are 296 as of today. Toni 001 (talk) 11:19, 19 October 2019 (UTC)

By the way, I had looked at such a mapping some weeks ago and found that about half of the WL entity types have an exactly (or very closely) corresponding Wikidata item, so in the first round there will be about 150 values. Toni 001 (talk) 20:01, 19 October 2019 (UTC)
