by the Wikipedia definition, malachite should have more "Substance meronym of"?

https://en.wikipedia.org/wiki/Malachite

Targetting what? There is already a relation to 'copper' as the substance that composes this mineral

http://wn.mybluemix.net/synset?id=14798450-n at least?

jmccrae commented 3 years ago

Seems like it should be a hypernym link not a meronym link?

arademaker commented 3 years ago

From the wikipedia article first sentence

Malachite is a copper carbonate hydroxide mineral

I take Malachite as a kind of mineral containing copper (Cu2), carbonate (CO3), and hydroxide (OH)2. Note that carbonate is a mineral containing carbonate ion so maybe carbonate in the sentence is the ion? Hydroxide is https://en.wikipedia.org/wiki/Hydroxide and it is maybe duplicated in PWN http://wn.mybluemix.net/search?search_field=word_en&term=hydroxide.

Maybe @alexandretessarollo can add something here.

jmccrae commented 3 years ago

Yes, but the synset for 'carbonate' refers to any salt (compound) containing CO3, while the synset for 'copper' refers to the element by itself. The hypernym link would be consistent with the other modelling, e.g., compare 'lithane' and 'bauxite'.

I checked GBA Thesaurus and got this: http://resource.geolba.ac.at/mineral/427 Chemical Formula: Cu2(CO3)(OH)2; Major elements: Cu; Minor and trace elements: As, Sb, Ni, Ca, Fe, Mg; Group: Carbonates. Label according to www.ima-mineralogy.org/Minlist; www.mindat.org; www.handbookofmineralogy.org (IMA 2014)

It gave other references with extra information as well, such as https://www.mindat.org/min-2550.html (great some, tons of information). And according to this reference, it can be an ore of copper. One final reference is http://www.handbookofmineralogy.org/pdfs/Malachite.pdf.

So, to sum up: it is a mineral; is can be an ore for copper (Cu); it is a carbonate; and it should contain more meronyms. Whether to point the meronym to C, O, H or to CO3, OH (or even both options) is a matter os design decision..
