Remaining metadata for VOEventRegExt

[Matthew Graham]

Hi,

In a final attempt to get VOEventRegExt - the registry extension spec for VOEvent infrastructure -, we need to figure out what the minimum amount of metadata we want to collect in a registry record related to publishing and querying events is. Does a reference URL suffice or is there more that you would want to see when doing resource discovery to help you figure out whether this is the one you want to use?

	Cheers,
