They are similar in that they both need to get information about updates, and a way to reindex. Full text search can be a little lazier, as being 100% up-to-date isn't such a big issue. >> That said, there's a real need for cross-system indexing of different >> kinds.

Actually, it's really a many-to-many notification system that's needed. We have one that needs documenting and review (http://www.openplans.org/projects/cabochon/project-home) but while it handles notifications and events (as do several other systems), that doesn't cover reindexing the site. And then you also need a set of useful endpoints, but those can grow over time. -- Ian Bicking : [EMAIL PROTECTED] : http://blog.ianbicking.org _______________________________________________ Repoze-dev mailing list Repoze-dev@lists.repoze.org http://lists.repoze.org/listinfo/repoze-dev
