Motivatie

[edit]

Catalog for collectors with stable identifiers for information about stamps, coins and postcards. They have identifiers for every published work, but also they do have identifiers for valuable terms in that concept, for example in the coin catalog they do have identifers for publishers, values, shapes, countries, materials, designers, medallists and head of states. This proposal focuses on these concepts, we could create another property for the items that has an url with 'item' (2½ cents (Q4634011) -> 178501 ). On a page for a coin they publish year, designer, weight, title, value and so on. That information is collected by a community of collectors. Pages are available in four languages. In certain languages background information is available Hannolans (talk) 15:54, 19 January 2022 (UTC)[reply]
