## Steps to reproduce
I am testing creating an item with 18 claims corresponding to 18 datatypes in a fresh Wikibase instance. Because the datatypes in a third-party Wikibase instance do not work out-of-the-box, I installed extensions and made a few changes in LocalSettings.php.template and docker-compose.yml. My reproducible experiment is available at https://github.com/UB-Mannheim/RaiseWikibase#testing-all-datatypes.
## Expectations
All properties with any of the 18 datatypes work without problems and without any error messages.
## What happens instead
The page for the item with 18 claims looks like this:
{F34195509}
1) The property 'geoshape' with datatype 'Geographic shape': the map IS NOT RENDERED in a browser. What should be done in order to render it?
2) The property 'musical motif' with datatype 'Musical Notation': problems with Lilypond, it is not found. Well, it's simply not there. Is it not sufficient to install 'Score' extension?
3) Lexemes, forms and senses: the error messages "Formatting error: Unknown data type '%'." appeared. Is it not sufficient to install extensions 'WikibaseLexeme' and 'Form'? In principle, they seem to work, the links are clickable, but the error messages appear anyway.
4) To embed a map, I needed to install Kartographer extension. To run Kartographer, I needed JsonConfig extension. Then I need to change a tile server $wgKartographerMapServer to a non-Mediawiki one, but even this is still not enough, see [T271617](https://phabricator.wikimedia.org/T271617) and [T259868](https://phabricator.wikimedia.org/T259868).
5) There is also a debug message "[resourceloader] ResourceLoader duplicate registration warning. Another module has already been registered as wikibase.Site". It looks the same as in [T267848](https://phabricator.wikimedia.org/T267848).
## Suggestions
Documentation for Data Types needs more explanations. Right now there are no information about what kind of extensions we need for each datatype.
