Thanks, that would be a great topic if some of the guilt—I mean, relevant parties are going to be there. I will come with a topic or two, but the hackathon model is that folks with an idea like this stand up and say “I want to work on X”. And people who also
want to work on X collect themselves at a table. That would be a good example. </div>

FYI all, I still need to check the attendance against the metadata oddities my script finds. I’m also trying to do what I assigned myself a year ago and fix our subjects to be from the UAT, and I’m finding some issues I’d love to discuss. </div>

<div class="ms-outlook-mobile-reference-message skipProofing">Hi, I have a topic to discuss at the hackathon - related to https://github.com/ivoa/registry-housekeeping/issues/10 - it turns out that there are several registry implementations that suffer from
similar problems - i.e. XML validation fails on the returned OAI records - often due to missing namespace declarations, but there are some other issues too. This might be well-known - I have not attended the recent hackathons… Paul.
