You could be more specific about the class of structures and the
domain of biology:
"A Perl module for reading, writing, accessing, manipulating, and
analyzing biological macromolecular 3D structures.
Goal: Provide a standard and convenient representation for molecular
biological structures (nucleic acid and proteins) as well as core
data-management and analysis features." (don't forget the period :)
>From our discussion of 2D structures in July, I think there is agreement
that the Struct module should not deal with both 2D and 3D structures.
Objects that represent a molecule's 2D structure would be handled by a
different module which could be associated with either a 1D or 3D
structure by a delegation mechanism.
Some more thoughts on the 2D vs. 3D issue:
3D structures *contain* 2D information, so a 2D structure object should
be derivable from a 3D structure object. If you believe Anfinsen, 1D
sequences contain 3D (and therefore 2D) structural information. The point
here is that there is redundancy in biological data. To be really useful,
the Bio:: modules should account for this, keeping the violations of good
software engineering principles to a minimum. Although tempting, we
should not sacrifice biological robustness for the sake of good s.e.

Put "Saccharomyces Genome Database" in place of "SGD database".
