Hmm.. I seem to remember Harvest being an old cache project that the Squid folks picked up on. HTTP Caching and Cataloging the same problem? Perhaps I am thinking of something different, or perhaps the harvest project had more goals than just caching. One problem with other cataloging/indexing tools is that they are, at best, designed to index URLs. This is al find and good, but we want to catalog object and their attributes, this is very Zope and Python specific. htDIG for example, will index all the documents on your site, but will it tell you the last document a certain Zope user modifed was? Will it give you a list of the 10 most recent news items (how can it know what are 'news items' without a meta_type?)? Also, with ZClasses, you can create your own objects and therefore they can have their own attributes. Let's say you made a car object, and it had a manufacturer attribute, someone elses cataloging package wouldn't be able to allow you to search for a certain care made by Ford before a certain year, becaause all of thesse attributes are specific to your application. These are the kinds of problems our Catalog is designed to solve (in addition to good old fasioned free-text searching). -Michel

Seems catalog in solving the same problem.
