Date ranges

[genericusername3]

Many conferences (and thus, conference proceedings) have date ranges instead of dates, and I'd like to specify the start and end date of a conference. One option would be to follow the ISO 8601 standard (or at least what Wikipedia claims it is), and use <start-date>/<end-date>, like so:

[...]
  parent:
    type: proceedings
    publisher: IEEE
    date: '2022-05-16/2022-05-19'
    title:
      value: 2022 22nd IEEE International Symposium on Cluster, Cloud and Internet
        Computing (CCGrid)
      short: 2022 22nd IEEE Int. Symp. Cluster, Cloud and Internet Comput. (CCGrid)
    location: Taormina, Italy

Could there be an option for this?

Even better of course would be to also support missing values in the end date, like '2022-05-16/19'

Or subfields?

So normally:

date: 2022-05-16

Range:

date:
  start: 2022-05-16
  end: 2022-05-19

Or since page-range exists, it could also be called date-range. But that's probably more confusing.
