In the Stack Exchange Data Explorer you can find the Moderator nominations by querying the Posts Table for posttypeid = 6, like so:
select id as [Post Link] , score , owneruserid as [User Link] , creationdate from posts where posttypeid = 6 order by score desc
As you can see I used the Post Link magic column, however that link doesn't work, in the first place because there is no title in those particular rows nor does the link bring you to the nomination post. Funny enough revisions does work.
Looking at a specific election page, for example election 8 on SO I can find the nomination posts and looking at the html, a nomination is wrapped in div with an post id:
<div style="border-bottom: 1px solid #AAA; padding-bottom: 20px;" id="post-40474659"> </div>
So for Aaron Hall I would need an url that looks like this:
where 40474659 is the postid of Aaron's nomination. What I'm missing is the
8 being the number of the election.
I did look at Magic number in Data Explorer should be documented and of course the standard Database schema documentation for the public data dump and SEDE but none of those mention the election part of nominations.
For a given moderator nomination how can I obtain the election number?
