Bookmarked Web Annotation Data Model by World Wide Web Consortium (W3C)
I wasn’t aware of it, but there’s a W3C model for annotations (in JSON). It was mentioned in the book Annotation I’ve been reading in the past weeks. Not sure if this is something I have a use for, but it may be an interesting way to transform and share book notes on this site. It was suggested that Hypothes.is uses this model. There’s also a Hypothes.is API which suggests it might be possible to pull annotations from there, although I don’t suppose you could push them there as a way of publishing annotations.
The Web Annotation Data Model specification describes a structured model and format to enable annotations to be shared and reused across different hardware and software platforms. … The specification provides a specific JSON format for ease of creation and consumption of annotations based on the conceptual model …, and the vocabulary of terms that represents it. This specification was derived from the Open Annotation Community Group’s outcomes. … This document was published by the Web Annotation Working Group as a Recommendation
