The practice of syndicating and then aggregating content into one stream is a useful one as more and more services crop up that allow us to do things that translate well into syndication formats.
There are two questions initially to be resolved:
- how can chronological microformats at the distributed sources be best used to feed into lifestreams (i.e. via hAtom, hCalendar)?
- how should lifestreams themselves be best marked up (using a combination of hAtom and hCalendar or one or the other)?
In Jeremy's Real-World example (and subsequent derivatives) a combination has been used. Is this the best path forward? Are there other ideas, especially for semantically linking to the types of services that appear in one's stream?
