adding 'format' property to StringProperty?

[lzehl]

Idea: a StringProperty is a user-defined key-value pair that assumes a string. It would be great if a user could define in addition the format of the string value he/she provided.

Example:

• name: applicationDate
• value: 2022-09-13T20:20:39+00:00
• format: datetime

@apdavison @Peyman-N @UlrikeS91 what do you think?

I support this!

@UlrikeS91 @apdavison @Peyman-N if we implement this should 'format' be optional or required?

[UlrikeS91]

If it was required, we would need a "format" that represents the absence of it when there is just a string value used that doesn't follow a specific format.
So, I would lean towards optional to avoid that.

optional

@UlrikeS91 and @apdavison thanks. optional it is. Another question:
a) Do we define a StringFormat schema that format links to? That schema should have the properties label and regex.
b) Should we define this as controlledTerm and predefine there the most popular string formats?
c) Leave this as string (which might end up in a mess).
