PICS Label Grabber

Kyle Jamieson

The PICS label grabber application searches the WWW for PICS Labels and submits them to the label bureau of your choice.  It can be used to populate a label bureau for testing, or for any other label bureau purpose.

The PICS label grabber allows the user to specify three URLs, and three numbers corresponding to the amount of searching the robot should do starting at each URL.   The robot does a breadth-first search from each URL; i.e., all URLs immediately linked to the start URL ("child" URLs) are searched before any "grandchild" URLs.  The robot does not visit a page twice.  Once the robot visits a page, all PICS labels are extracted from that page and sent to a label bureau via an HTTP PUT.
