Re: ISSUE-15: Past, present and future

So far no-one has come up with another interpretation. So I would like to
propose a wording for the requirement:

"It should be possible to declare that a web resource is in the past,
present or future with respect to another web resource"

How about that? Could that be something to vote on next Wednesday?

Regards,
Frans
