You might have a look at Droids (http://incubator.apache.org/droids/) or Nutch (http://lucene.apache.org/nutch) and their communities. They are much more focused on crawling (not to say there aren't people here who crawl, just saying those projects are (mostly) about crawling)

Hi...

Sorry that this is a bit off track. Ok, maybe way off track!

But I don't have anyone to bounce this off of..

I'm working on a crawling project, crawling a college website, to extract course/class information. I've built a quick test app in python to crawl the site. I crawl at the top level, and work my way down to getting the required course/class schedule. The app works. I can consistently run it and extract
the information.

My issue is now that I have a "basic" app that works, i need to figure out how I guarantee that I'm correctly crawling the site. How do I know when I've got an error at a given node/branch, so that the app knows that it's
not going to fetch the underlying branch/nodes of the tree..

How do I know when I have a complete "tree"!

I'm looking for someone, or some group/prof that I can talk to about these
issues. My goal is to eventually look at using nutch/lucene if at all
applicable.

Any pointers, or people, or papers, etc... would be helpful.

Thanks
