Recently I’ve been looking into blog/content aggregation for a variety of purposes:
- gathering a single person’s output across heterogeneous systems
- taking a single post and repurposing in multiple outputs in a single internal system
The former requires one to externally reference (but to probably mirror for convenience) the content, but the latter of course can be accomplished simply by extending the data model to assign m:n relations for posts:outputs.
Another alternative for the latter is to use Trackback (example) although the pinging interface is pretty limited, allowing only a 252 character excerpt, and without Author, posting (not ping) date, etc…
