Rich Media TWG
Background
Back in the ancient days of 2008, in Adobe’s Supplement to the ISO 32000 specification (Base Version: 1.7 Extension Level: 3), Adobe introduced not one but two Annotation types for embedding 3D content, one of which also promised to allow audio and video content better than prior multimedia annotations. That multi-purpose annotation was the RichMedia annotation.
This annotation has not yet seen wide adoption. Starting in 2021 the Rich Media Technical Working Group has made it their task to develop guidance and best-practices for implementing rich media in PDF.
Objective
Specific areas in which we plan to invest:
- Embedding 3D models in PDF/A-4 documents
- Examining the audio and video capabilities of RichMedia annotations
- Guidance on configuration and use, including ECMAScript
- Describing and documenting implicit assumptions
- Research and develop new proposals related to animation and other future rich media capabilities for the next generation of PDF (an outcome from the Symposium on Advancing the PDF Imaging Model)
