The Web Annotation Data Model is the [[W3C]] recommendation from February 2017. [[Hypothes.is]] wrote a blog post about the official standard being finalized.

Annotations are typically used to convey information about a resource or associations between resources. Simple examples include a comment or tag on a single web page or image, or a blog post about a news article.

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. Common use cases can be modeled in a manner that is simple and convenient, while at the same time enabling more complex requirements, including linking arbitrary content to a particular data point or to segments of timed multimedia resources.

The specification provides a specific JSON format for ease of creation and consumption of annotations based on the conceptual model that accommodates these use cases, and the vocabulary of terms that represents it.
