mod_aggregation

Synopsis

The Aggregation module plays a small but useful part in the lifecycle of information passing through the Web. It allows news aggregators, such as those covered in Chapter 2, to display the sources of their items. These services gather items from many other sources and group them by subject. mod_aggregation lets you know where they originated.

This, of course, works over generations: as long as the mod_aggregation elements are respected, a Meerkat feed that uses a Snewp item from a Moreover feed that is itself an aggregation (for example) still has the original source credited. As long as the mod_aggregation elements are left in place, the information is preserved. There isn’t, as yet, any feature for describing an aggregation history, however; you only know about the primary source. You also can’t necessarily trust the contents of the element either, but this is more a social issue than a technological one.
