Tulip Chain is a DMOZ editor tool - that may also be called a bot. Unlike Robozilla (see Robozilla Exposed), it does not run automatically, but is initiated by an individual editor for a specific category or group of related categories.

It allows checking if sites within a category are working, and also provides additional inforamtion about redirects and bad links.

It will typically leave a user agent in your access logs something like TulipChain/6.02 (http://ostermiller.org/tulipchain/) Java/1.5.0_04 (http://java.sun.com/) Windows_98/4.10 RPT-HTTPClient/0.3-3
