Crawl interfaces, suggested

Initial Crawl-window

To crawl most pages elegantly and easily, you need five information elements:

1. Somewhere to start. Which place do you want your crawler to start. You don’t have to specify the domain, we pick the domain name  from the page you’re visiting.
2. Which links to follow. This is not necessarily the pages you want to crawl. Typically these pages have lists of pages you want to crawl.
3. Which links not to follow. To not make the crawler go wild, you set some boundaries. Often a page has several URLs.
4. Which links to crawl. These are the actual pages you’re looking for.
5. Which links not to crawl.

A simple illustration on the above rules. Forage Fetch doesn’t have all these features yet, but they’re suggested as enhancements.

Selecting which rule type to add

To ensure you’re adding valid rules, it’s a good ting to test first.

Next tasks will be to make a clickable prototype in HTML/CSS and read up on HTML5 local storage/web storage.

All comments on the idea are welcome! Here’s what we’ve blogged about Forage so far.
