feat(ontology): display description for default and existing props (DSP-1154)

[kilchenmann]

resolves DSP-1154

[kilchenmann]

The description from the default properties will be displayed as tooltipp:

@mdelez could you check the english sentences? Thanks

[gautschr]

I suggest for "Text":
"Short text such as" instead of "Small text like"

A question concerning Date/Time: The inclusion of the new GUI element which allows for a proper display of dates with lower precision than one day - is this another PR?

I will update as suggested. → done in 6fb9746

The new gui element for dates should already be implemented. So yes, how should the description look like?

[mdelez]

We should probably clarify that this is a hexadecimal value. Ex: "A hexadecimal color value"

[kilchenmann]

I am not sure if everyone understands the term "hexadecimal". Apart from that, in the GUI we have the color picker only and the hexadecimal value itself is not displayed anymore (s. DSP-1667)

[mdelez]

That's fair :)

[mdelez]

is this code still needed?

[kilchenmann]

I'm not sure if we have to reactivate it one day!?

[gautschr]

We need a kind of dd/mm/yyyy BCE/CE icon and for the short description I suggest "dd/mm/yyyy format; for historical dates"
