We categorify the inclusion-exclusion principle for partially ordered topological spaces and schemes to obtain spectral sequences that generalize the two spectral sequences of a stratified space and certain Vassiliev-type spectral sequences. We also obtain Euler characteristic analogs in the Grotendieck ring of varieties. The work is joint with Sean Howe.
