EDTF validation levels 1-3
Valid EDTF provides validity testing against EDTF levels 1-3. You might find it most useful for tasks involving date validation and comparison. Typical usage often looks like this:
#!/usr/bin/env python from valid_edtf import isLevel1 if isLevel1(edtf_candidate): print "The date, %s, is level 1 edtf validated" % edtf_candidate
