I’m using the following general markup to make this happen:
<blockquote><link rel="canonical" href="https://www.example.com/annotated_URL">
Text of the thing which was previously annotated.
Let’s give it a whirl:
This summer marks the one-year anniversary of acquiring my domain through St. Norbert’s “Domain of One’s Own” program Knight Domains. I have learned a few important lessons over the past year about what having your own domain can mean.
The first issue that I never really thought about was the security and privacy on my domain. A few months after having my domain, I realized that if you searched my name, my domain was one of the first things that popped up. I was excited about this, but I soon realized that this meant everything I blogged about was very much in the open. This meant all of my pictures and also every person I have mentioned. I made the decision to only use first names when talking about others and the things we have done together. This way, I can protect their privacy in such an open space. With social media you have some control over who can see your post based on who “friends” or “follows you”; on a domain, this is not as much of a luxury. Originally, I thought my domain would be something I only shared with close friends and family, like a social media page, but understanding how many people have the opportunity to see it really shocked me and pushed me to think about the bigger picture of security and safety for me and those around me.

Unfortunately, however, I’m noticing that if I quote multiple sources this way (at least in my Chrome browser), only the last quoted block of text transcludes the Hypothes.is annotations. Based on prior experiments using rel-canonical mark up I’ve noticed this behavior, but I suspect it’s simply the fact that the rel-canonical appears on the page and matches one original. It would be awesome if such a rel-canonical link which was nested into any number of blockquote tags would cause the annotations from the originals
Perhaps Jon Udell and friends could shed some light on this and or make some tweaks so that blockquoting multiple sources within the same page could also allow the annotations on those quoted passages to be transcluded onto them?
Separately, I’m a tad worried that any annotations now made on my original could also be mistakenly pushed back to the quoted pages because of the matching rel-canonical without anything taking into account the nested portions of the page or the blockquoted pieces. I’ll make a test on a word or phrase like “security and privacy” to see if this is the case. We’ll all notice that of course this test fails by seeing the highlight on Cassie’s original. Oh well…
So the question becomes, is there a way within the annotation spec to allow us to write simple HTML documents that blockquote portions of other texts in such a way that we can bring over the annotations of those other texts (or allow annotating them on our original page and have them pushed back to the original) within the blockquoted portions, yet still not interfere with annotating our own original document? Ideally what other HTML tags could/should this work on? Further could this be common? Generally useful? Or simply just a unique edge case with wishful thinking made from this pet example? Perhaps there’s a better way to implement it than my just having thrown in the random link on a whim? Am I misguidedly attempting to do something that already exists?
