1) I'm not sure what you mean by 'class data'. Every SPOPS class stores its configuration in a hashref accessible with $class->CONFIG, and the values in that hashref can be any normal Perl scalar (hashref, arrayref, etc.)

If you mean 'instance data', then that's a different matter. Serializing hashrefs and arrayrefs to a database is nontrivial, although the SPOPS::LDAP implementation does this fairly well.

2) You can define one or more classes in 'code class' whose methods get read into the generated class at initialization.

3) If you've downloaded the SPOPS source, check out the 'eg/' directory for a number of examples (see the README file there for pointers). The documentation (also web accessible) has a number of examples scattered throughout as well.

Also, feel free to post questions to the openinteract-help mailing list (that's where SPOPS is supported).
