Thanks @davidB - we discussed this topic during the last CDEvents WG and we plan to include it in the next milestone v0.5. We'll try to have most of the breaking changes in one milestone (v0.5). Once the v0.4 release is out (this week), this PR will have to be rebased and the version of the affected events updated.

[afrittoli]

@davidB - main is now open for v0.5 development - could you rebase your PR based on top of the updated main?
@xibz @obowersa this PR is related to #162 and cleanup/consistency work we plan for v0.5.

[davidB]

@afrittoli The PR is rebased on main.

We should rename URL to URIs

@xibz I renamed every field named url into uri. But kept viewUrl as is.

[davidB]

@xibz / @afrittoli Can you merge the PR (I'm not allowed).

Thanks @davidB - the change looks good.
Since all event versions have been bumped already and are currently in -draft this looks fine, no further updates required.
