When you look inside the corpse of the conversion you see

a SQL database containing 2500 items up to 2002

(This is just a short note to say that the conversion was fairly labour intensive, but it went very well.)

I should cover this in case it’s interesting to someone in the future approaching the same sort of problem.  As far as I can see, and I’m only in the very earliest stages of verifying data, the decision that was made during the change over from “anti-” to “allowed: ” seems to have been as follows

• Alignment conversion is trivial, it’s obvious how this works.
• If an item was anti a particular class make it anti the new genre the class belongs to.  If something was anti-warrior make it allowed everything except fighter and so on.
• Some items need touching up, the one that leaps to mind is “Sun, Moon and Stars”, but that was because it used a wear program to enforce it’s restriction against warriors but allowed rangers and paladins – from the conversion point of view, this is something different than anti’s.
• There will be items that have changed over the last 10 years.  Again, not a conversion issue.
