Mikel on aggregators September 19, 2003 Mikel Maron: There are many unsolved and half-solved problems in aggregation software. And at least there's no one place to find the consensus, or pros and cons on each issue. Examples.. : auto-discovery formats : methods for publishing blogrolls and subscription lists, and interchanging them among aggregation tools : aggregation subscription methods : methods of passing “read articles” among multiple aggregators : rpc api’s for aggregators : update frequency, and methods of update notification : authentication : standards for handling weblog comment aggregation and many many more.
