Hi Simon,

Thanks for that. It's not strictly necessary that the registration template appear in the specification document, although it is thought to be helpful by some.

For the registry correction, as you're the editor of the document, I'm assuming this is something that represents that community as a whole. 

IANA, could you please update the description of the "intervalMetBy" entry in the Link Relations registry to:

"""
refers to a resource associated with a time interval whose end coincides with the beginning of the time interval associated with the context resource
"""

?

Kind regards,
