Hi Blakem,
Appreciate your thoughts and agree with your perception:

Not to disappoint you, but I haven't considered prolog for this task, as the entire system is written in perl.
What this means that it gives us an opportunity to mimic prolog/logical programming via perl modules and operator overloading.

First we list some "Truths" about our world, then we attempt to derive the truthfulness of other relationships, based on the principals of logical reasoning.
I defintely liked your verbal derivation of the problem. What I have mentioned is just a simple ranking problem. Your idea could be applied in general and we can prepare a complex data set to come up with the complicated query.
More pointers in this direction, if you have done some research, would be definitely helpful.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
