[OPEN-ILS-DOCUMENTATION] FW: [OPEN-ILS-GENERAL] Question regarding circulation policies

[June Caola-Stokoe]

Hi All,

Since participating in the Hackfest, I'm curious about this... As with the attached example,  I see many instances on the General email list that a very busy contributor generously takes the time to give a comprehensive answer to a question.  Would it be beneficial simply to add the text Launchpad to insure, if not already present, that the information resides in the documentation to perhaps become a starting point to fill it in.

... or maybe that's another action item for DIG to comb the General  list discussions to pull out items that are useful to add... or perhaps someone has already done it?

Hi Deana,

Your question touches on the issues of weighting.  Policies are made to use weights as you define them under Admin -> Server Administration -> Circulation Matchpoint Weights.  So, if you put no weight to a given variable (user groups, location, circ mod, etc...) it actually won't matter at all.  When a circulation is invoked the variables for the circulation are compared to those weights and the policies that could potentially be matched are looked at to see which is invoked.  In case of a tie the lowest value id on in the table is used, IIRC.

So, it's not so much a hierarchy as a which is the best match.  Now, you could use weights and design your policies to create your own hierarchy (as we've done where each county has its own rules).  To accomplish this our circ libraries have a very high weight so that their rules take effect.
