Introduce "_formats": "year"

[UlrikeS91]

@olinux, could we create a new "custom" format for year? At the moment, we us a regular expression (([0-9]{4})) for the property "year" in the copyright schema because draft-07 doesn't have this as a regular format (only date and/or time).

This would mean some changes to the generator as well ;)

This can be postponed to a later point. But good to keep open for now.

@olinux it would be good to receive your input here.

This topic got revived. There are several fields where it would be an advantage to give a bit more flexibility in what is provided than just datetime or date.

My suggestion would be to keep a list of the following for date/datetime/time:

• yyyy
• MM/yyyy
• dd/MM/yyyy
• dd/MM/yyyy HH:mm (?)
• dd/MM/yyyy HH:mm:ss (?)
• dd/MM/yyyy HH:mm:ss.SSS
• HH:mm (?)
• HH:mm:ss (?)
• HH:mm:ss.SSS
