Text, as the Hypothesis annotation client understands it, is HTML, or PDF transformed to HTML. In either case, it’s what you read in a browser, and what you select when you make an annotation.
What’s the equivalent for audio and video? It’s complicated because although browsers enable us to select passages of text, the standard media players built into browsers don’t enable us to select segments of audio and video.
It’s trivial to isolate a quote in a written document. Click to set your cursor to the beginning, then sweep to the end. Now annotation can happen. The browser fires a selection event; the annotation client springs into action; the user attaches stuff to the selection; the annotation server saves that stuff; the annotation client later recalls it and anchors it to the selection.
But selection in audio and video isn’t like selection in text. Nor is it like selection in images, which we easily and naturally crop. Selection of audio and video happens in the temporal domain. If you’ve ever edited audio or video you’ll appreciate what that means. Setting a cursor and sweeping a selection isn’t enough. You can’t know that you got the right intro and outro by looking at the selection. You have to play the selection to make sure it captures what you intended. And since it probably isn’t exactly right, you’ll need to make adjustments that you’ll then want to check, ideally without replaying the whole clip.
Jon Udell has been playing around with media fragments to create some new functionality in Hypothes.is. The nice part is that he’s created an awesome little web service for quickly and easily editing media fragments online for audio and video (including YouTube videos) which he’s also open sourced on GitHub.
I suspect that media fragments experimenters like Aaron Parecki, Marty McGuire, Kevin Marks, and Tantek Çelik will appreciate what he’s doing and will want to play as well as possibly extend it. I’ve already added some of the outline to the IndieWeb wiki page for media fragments (and a link to fragmentions) which has some of their prior work.
I too look forward to a day where web browsers have some of this standardized and built in as core functionality.
Highlights, Quotes, & Marginalia
Open web annotation of audio and video
This selection tool has nothing intrinsically to do with annotation. It’s job is to make your job easier when you are constructing a link to an audio or video segment.
(If I were Virginia Eubanks I might want to capture the pull quote myself, and display it on my book page for visitors who aren’t seeing it through the Hypothesis lens.)
Of course, how would she know that the annotation exists? Here’s another example of where adding webmentions to Hypothesis for notifications could be useful, particularly when they’re more widely supported. I’ve outlined some of the details here in the past: http://boffosocko.com/2016/04/07/webmentions-for-improving-annotation-and-preventing-bullying-on-the-web/
