There's another way... more below...

Ah, but it is very closely related to what we're doing... and with
minimal effort, we can transform it into an RDFa issue.

I don't think that it is a stretch to say that we would all be delighted
if Twitter started publishing all of their pages in XHTML+RDFa. They're
already publishing in XHTML.

The data that they're publishing in Twannotations (I've tried to use
that phrase for the past two days and it still sounds awkward), is
effectively RDF/EAV/Triples.

The goal isn't to get them to buy into a new JSON encoding of RDF... I
doubt that approach would work. The goal is to try to get them to
express their data in a way that is easily transformed into XHTML+RDFa
while simultaneously not creating a great deal of work for them. The
only thing that is required of them is the adoption of CURIEs for
properties and some very minor code on their front-end to transform the

The key isn't to try to get them to see the world according to our
eyes... it's to establish a known, deterministic transformation
mechanism to turn Twannotations into XHTML+RDFa. This would enable:

* Twitter to publish XHTML+RDFa, and therefore real-time semantics, for
  any user's timeline.
* Anybody that uses Twitter to transform Twannotations into (X)HTML+RDFa
  using the same mechanism.

All Twitter needs to state is:

1. The prefix mappings that developers can use in property values.
2. The algorithm for mapping Twannotations to HTML+RDFa.

Both #1 and #2 are trivial to specify and they don't require Twitter to
change /anything/ about their software platform (other than state that
CURIEs will be interpreted in a certain way).
