The ODbL (potential future OpenStreetMap license) relies on the meaning 
of "Substantial".

The ODbL 1.0rc defines it as:
"Substantial" - Means substantial in terms of quantity or quality or a 
combination of both. The repeated and systematic Extraction or 
Re-utilisation of insubstantial parts of the Contents may amount to the 
Extraction or Re-utilisation of a Substantial part of the Contents.

On behalf of the Licensing Working Group I have started a wiki document 
to define what we as a project believe "Substantial" to be in 
OpenStreetMap's context.

The ODbL 1.0 Release Candidate is available here:
