Mineral list





  • This page aims to organize a consensus view of the properties that describe minerals. Please be bold and add your suggestions below!

Rules of this page:

  • Feel free to add new property for discussion in the tables. Set the "Creation level" to Proposal
  • Please use the talk page to discuss about properties creation or use. If you want to discuss a property, create a new section on the talk page and set the "Creation level" to 'discussion and link the property in the table with the section.

Wikidata data structure

[[|thumb|upright=2|Overview of a Wikidata statement]]

  • Wikipedia articles are items on Wikidata. They are stored as a number which has a Q in front of it. Quartz for example is Q43010.
  • An item can have many statements.
  • A statement consists of a property and a value.
  • The value can have different data formats.
  • String: Quartz has the IMA-number "1967 s.p.". This string is not translated into other languages because it is the same in every language.
  • Value: Quartz has a density of "2.65". A value can be used for calculation and it gets translated into other number systems (e.g. different comma used in language "2,65")
  • Item: Quartz is a mineral. Mineral has its own Q-number and is therefore an item. Using items for statements reduces the amount of translating one has to do.
  • Multi-lingual string: A multilingual string has to be translated. These are descriptions that don't exist as items.
  • Qualifiers: Every value can have a qualifier. The density of Quartz for example should have the qualifiers at what temperature and pressure these measurements where made.
