Re: [dxwg] How to model dct:temporal for continously evolving Datasets? (#1403)

Hi, not so familiar with semantic web, but we are trying to provide metadata for schedules and models covering different periods of time, but are sent with specific periodicity. Any recommendation how to do this with dcat.

There is two needs:
1. Define process, publication event reoccurrence - here we would like to use cron syntax - https://crontab.guru/
2. Define process publication temporal coverage in a dynamic way

Example of dynamic period definition
