As a compromise, one could always add a comment to every sequence with a
given property (e.g. "ogf is rational", "a(n) has period 17", "a(n) is
monotonically nondecreasing", "a(n) is an oligomorphic permutation of
N" (already commented as such!), "conjectured" (for each of many 
possible properties that are unproven), etc, etc...).

Keywords are nice for standardization, but there really could be quite
many. And with the new search capabilities, it's not too hard to take
into account all variations.

It would be easy to give a list of descriptors that people should
consider when submitting. The keyword checkboxes on the submission page
are followed just as well (sometimes yes, sometimes no).

Maybe keywords should be restricted to non-mathematical properties or
those that are relevant to management of the database.
