OpenAnnotation

OpenAnnotation is an open standard that enables people to add comments, highlights, or notes to digital content like web pages, PDFs, or images. It creates a consistent way to create, share, and manage annotations across different platforms and tools. For example, researchers can highlight text and add comments on the same document, regardless of the software used. OpenAnnotation promotes collaboration by making it easier to discuss, annotate, and analyze digital resources in a standard, interoperable way.
