Slovakia is a blank area on our map....

Dear Daniel, I just realise that we have the Czech places on FactGrid, but not the localities of Slovakia. I have not checked whether the Wikikdata set would be good source - but I fear you will soon need these. --Olaf Simons (talk) 11:56, 2 May 2024 (CEST)

Dear Olaf, I will soon work on the localities. Will think about it. --Daniel Baránek (talk) 11:58, 2 May 2024 (CEST)

As inhabited places they should all have a P2-Q8 statement, simple but useful in order to get quick datasets of a country. If you want to specify the status you can do this with P560-Q#. --Olaf Simons (talk) 12:36, 2 May 2024 (CEST)

P131 Statements

...you should also have an P131-Item to represent your research Project on FactGrid. This is a good example: Item:Q11305. You can eventually use that to select all items you have been working on. --Olaf Simons (talk) 15:16, 2 May 2024 (CEST)

Thanks for the hint. --Daniel Baránek (talk) 15:24, 2 May 2024 (CEST)

I also created a project space which you can access through the project space menus. The other projects will give you ideas - but it seems you have not arrived without any ideas of your own. User:David Löblich has created a project on the Jewish History of Saxony-Anhalt and User:Michael Wermke, professor in Jena, is thinking of a project on Jewish schools in Germany, in which he wants to explore the networks of their teachers. --Olaf Simons (talk) 22:48, 2 May 2024 (CEST)

• FactGrid:The Jewish History of Bohemia

Great, thanks, I will write more about my projects little bit later. --Daniel Baránek (talk) 22:56, 2 May 2024 (CEST)

Thanks on my side, I did not realise that there were so many places without geocoordinates! I should have asked SPARQL.. --Olaf Simons (talk) 23:01, 2 May 2024 (CEST)

Just to let you know: I have upgraded you to Admin, so that you can run regular Quickstatements inputs etc. with greater ease. (Most of us are Admins here.) --Olaf Simons (talk) 08:01, 3 May 2024 (CEST)

Small thing: In German, English, French and Spanish we start all Labels with capital letters (with the exception of name components like "von Goethe" or company names that are explicitly formulated in lowercase letters. (the advantage is in regular searches the alphabetical order) --Olaf Simons (talk) 08:18, 3 May 2024 (CEST)

Houses

Dear Daniel, if you want to locate people in houses, please take a look at User:Laurenz Stapf's work on Leipzig to synchronise the data models. He again took a look at User:Bruno Belhoste's work on Paris. It is cool to create these data! --Olaf Simons (talk) 07:00, 7 May 2024 (CEST)

Thanks. I have created FactGrid:Buildings data model and invited both of them to comment it. --Daniel Baránek (talk) 12:46, 7 May 2024 (CEST)

Dear Daniel Item:Q923611 the P2-Residential building is only on your houses. All the others stated: Property:P2-Item:Q16200 to marke the entire ground that belongs to an address. --Olaf Simons (talk) 23:42, 9 May 2024 (CEST)

Well, this could be easily solved by Q701396:P3:Q16200, because every residential building is a real estate. --Daniel Baránek (talk) 23:49, 9 May 2024 (CEST)

Theoretically you are right. Do a wdt:P2/wdt:P3* (Instance of or Sub-property) search and you have it. The problem is that the evolving ontologies are precarious on both sides of the coin: People do not get the complete ontologies right. They create more and more precise items that are subclasses of something or other and assume they get a perfect ontology up to the top, but fail. They get things tat lead up to different top terms as they think that this or that should be on top of the ontology. In the end it becomes increasingly difficult to ask the right question in the mix of approaches within the pseudo categorical systems they created. (Graph databases are not very transparent here - I say this as a am a huge fan of graph databases.) The other problem is: the Query Service breaks sooner or later. It does not crawl through the ontology on bigger datasets. 30.000 items with just one unified P2-Q-value are easy to grab - you still get the whole city of Paris on the map. The same with a complex hierarchy of things and you get a time out. Wikidata does not provide good models of entire cities - as complex and large as User:Bruno Belhoste's Paris on FactGrid. We went to the technical limits and learned. (Besides: It does not make sense to have your data on extra models). --Olaf Simons (talk) 00:14, 10 May 2024 (CEST)

Thanks for clarifying. So, should I use P560, or is there any better property? --Daniel Baránek (talk) 07:57, 10 May 2024 (CEST)

P560 is a good property to state the status of an object. A project in Karlsruhe is about to use it for the various German "Denkmalschutz" categories of buildings. If you have registers explaining what these things are, that's a good property to replicate and source the the status assignments. --Olaf Simons (talk) 08:43, 10 May 2024 (CEST)

Territorial entities

are usually countries, regions, provinces... --Olaf Simons (talk) 00:01, 10 May 2024 (CEST)

Human settlements

(comprising several houses/ addresses) should all be P2-Q8.

Use Property:P560 to assign a status like "Swiss Canton" or "(German) Kreisstadt" --Olaf Simons (talk) 00:01, 10 May 2024 (CEST)

Thanks, now I know. I will remodel it. --Daniel Baránek (talk) 00:06, 10 May 2024 (CEST)
