Many have tried over the years to bring us web annotations. The lack of standards has been one of the key things holding these efforts back– a need we highlighted in the first of our 12 original principles back in 2013 and have been working towards ever since.
Twenty four years after Marc Andreessen first built collaborative annotation into Mosaic and tested it on a few “guinea pigs” before turning it off, annotations have finally become first-class citizens of the web.
From the W3C Web Annotation co-chairs, Rob Sanderson and Tim Cole:
“Many websites already allow comments, but current […] systems rely on unique, usually proprietary technologies chosen and provided by publishers. Notes cannot be shared easily across the Web and comments about a Web page can only be saved and viewed via a single website. Readers cannot select their own tools, choose their own service providers or bring their own communities.”
So what exactly does this mean for you?
Comment widgets may soon become a thing of the past.
The W3C standards (called Recommendations) are a key milestone towards a future in which all pages could support rich layers of conversation without requiring any action by their publishers—because that capability can be built into the browser itself and be available as a native feature, just like web search. The shared vision is that conversations will be able happen anywhere on the Web, or even on documents in native apps, and inline instead of below-the fold, in a federated, standards-based way.
