@bad-example.com I want to experiment with constellation but I don't think I fully understand what a backlink is or the syntax of the `source` param. In this example, it's returning 16 likes on a post right? What is the `:subject.uri` for?

right! the “source” locates the actual like link from all the way *into* the like itself here’s a like: pdsls.dev/at://did:plc... :subject.uri says to look at the subject in that record content, and the uri inside that, to find the link

for likes it’s kind of obvious which link you probably mean, but even in that example there’s a separate “via” link in the like record so the “record path” after the : specifies exactly which source of link you want

it’s clearer with backlinks from app.bsky.feed.post records: you have links for quote-posting, replying (two links for each reply!), tagging, website links, hashtags, … the record path lets you filter to the specific type

Ah I see. I think that would have been more obvious if I knew the bsky lexicons better. Thanks for your help!
