clue

If a hyper link on target page is extracted and stored into a property, the operator of MetaStudio can determine if a clue should be created at the same time along which another target page can be navigated to. If it is, the property's attribute clue should be set. It asks DataScraper to make use of this address to create a new clue.

If a property's attribute clue is set, MetaStudio will automatically create a Info clue on the Clue Editor work board. In phase of Define clue extraction rules a theme name should be provided to this clue. The name can be same or different from that of current theme. The former means new created clues belong to current theme. The latter means they belong to another theme with a different data schema.

If the property's attribute clue is unset, the auto-created Info clue will be deleted automatically from the Clue Editor work board.

If a property's attribute clue is set, its attribute url will be set accordingly.
