Wikidata is a free knowledge base that you can edit! It can be read and edited by humans and machines alike and you can go to any item page now and add to this ever-growing database!
Need some help getting started? Here are some pages you can familiarize yourself with:
- Introduction – An introduction to the project.
- Wikidata tours – Interactive tutorials to show you how Wikidata works.
- Community portal – The portal for community members.
- User options – including the 'Babel' extension, to set your language preferences.
- Contents – The main help page for editing and using the site.
- Project chat – Discussions about the project.
- Tools – A collection of user-developed tools to allow for easier completion of some tasks.

Hallo Scoid d!
Kannst Du bitte imported from Wikimedia project (P143) nicht als eigenständige Eigenschaft bei Objekten verwenden, sondern nur in der Sektion Fundstellen. Danke Dir. --Plagiat (talk) 18:43, 1 December 2016 (UTC)

Item to be deleteEdit
Definition of alternative ingredients in Material (P:18)Edit
Is it possible to define in material P186 an alternative ingredients/ substitute? An example might be a table, which could be either made out of wood or metal or something different? best regards, --Scoid d (talk) 14:42, 2 September 2017 (UTC)
- We need a qualifier for "typical" parts and materials from "possible" and "compatible". d1g (talk) 06:13, 3 September 2017 (UTC)
- Other useful values might be "original/traditional", and "regional" (to be paired with "valid in place"). These would be very helpful for clothing and textiles which are often traditionally wool, silk, etc. but are now frequently synthetics or blends, or where different fibers are used in different places. - PKM (talk) 18:59, 4 September 2017 (UTC)
Definition of percentage of one of many ingredients in a mixtureEdit
How I can define e.g. "90% acetic acid" as one ingredient of other materials in a mixture, whose amounts are defined by percentages of the whole receipe altogether? In this example liquid cold glue from Brunner (Q37473980) I describe that 2 % of the total amount of the mixture of the material used (P186) is DL-lactic acid (Q161249). But how can I say, that the DL-lactic acid (Q161249) itself is a 2% solution, beside other solutions of different percentages of which the material is consisting of? --Scoid d (talk) 11:35, 17 September 2017 (UTC)
- I am sorry, but the difference between proportion (P1107) (e.g. used in steel (Q11427)) and quantity (P1114) is not clear to me and doubt, that it might solve my explanations for ingredients in a recipe. --Scoid d
- The value for proportion (P1107) should be a fraction between 0 and 1
- The value of quantity (P1114) is most usually an integer. Jheald (talk) 10:34, 18 September 2017 (UTC)
- I don't think you can use proportion (P1107) to specify the concentration, because if you have a statement like
- to specify the amount that goes into the mixture, then you can't also use P1107 to specify the strength of the DL-lactic acid (Q161249).
- We might need a new additional property here like "concentration", maybe also "molarity".
- An alternative would be to create a new item for "90% acetic acid", as itself a mixture; but that wouldn't extend well beyond the most very common concentrations of reagents. Jheald (talk) 10:44, 18 September 2017 (UTC)
- (ec) A further possibility, I suppose, would be to 'extract out' the water, so instead of saying 2% of a 2% solution, say 0.04% of the chemical plus 0.196% water. But that seems to me to be not great. Jheald (talk) 10:55, 18 September 2017 (UTC)
- Quantity = number of instances (an integer), proportion = relative amount. Curiously "percentage" is allowed with quantity, instead of with proportion. But indeed it is not possible to have qualifiers to qualifiers (2nd degree qualifiers). - Brya (talk) 10:51, 18 September 2017 (UTC)
Is somebody willing to formulate an appropriate proposal? I am eager to see more concise data flowing in, but without a new property this stops me feeding more data. --Scoid d (talk) 18:49, 19 September 2017 (UTC)
I see that in Q27131913 and other places you have modeled events as point in time (P585) statement with event itself as qualifier. This does not look to be correct - the property should be significant event (P793) (or other as applicable of course) and point in time (P585) should be the qualifier. Could you please fix it? Thanks in advance. Laboramus (talk) 04:59, 1 January 2018 (UTC)
