[OPEN-ILS-GENERAL] Help with Circulation Limit Sets & Groups

[Boyer, Jason A]

This is how we've got things set up in Indiana and they seem to be working well:

We don't use the groups for anything. (They're not at all related to user groups, but I'm having a hard time determining the point from a quick glance)

We have 4 entries in config.circ_limit_set: dvds, videos, games, and art. Since they're consortium-wide limits, the owning_lib is the consortium and the depth is 0.

There's an entry in config.circ_limit_set_circ_mod_map for each circ mod affected (i.e. several different dvd-related circ mods tied to the one dvd circ_limit_set)

Entries in config.circ_matrix_limit_set_map tie your limit sets to circ matrix matchpoints. This is where it may become tricky to apply them without having to canvas the whole circ matrix. We only mention circ durations in a single matrix matchpoint for each circ_modifier, so we only have 10 links between limit sets and those few circ matrix rows. (i.e. one from each dvd-related circ mod row to the dvd limit)

We have fallthrough=true on all of them; I think that's to cover the case where the first matching circ matrix row isn't connected to a limit, but $SRC/OpenILS/src/sql/Pg/100.circ_matrix.sql holds the answer to that question.

I'm sure there's much more you could do (and it would get much more complicated if you allow local control) but this is working well for us. I hope it helps!

Subject: [OPEN-ILS-GENERAL] Help with Circulation Limit Sets & Groups

Hi all,

We recently migrated from Evergreen 2.3.2 to 2.5.1, and I am having trouble separating out Circulation Limit Sets. In 2.3.2 I had Circulation Limit Sets set up for the majority of our items (books, etc.) at 999 (unlimited). I have Circulation Limit Sets for our DVDs and Magazines (5 items at a time). This should be 5 dvd's and 5 magazines max. However, for some reason the system is seeing them as the same type item (even though I edited the Circulation Limit Sets to include the correct circulation modifiers and broke up the original set "DVD, Magazine" into two separate sets). So if a patron has 5 magazines out they aren't able to check out even one DVD. We also have several other item types that are limited because of their type, and I want the system to be able to distinguish that a patron can have one item of AV equipment and one of our reusable carry bags checked out at the same time - but not two carry bags.

I am also not really clear on the impact of circulation limit groups on these policies. Are "sets" specific to items and "groups" specific to people?

I do not know for a fact that this was working in 2.3.2, as it is rare that this situation arises, but since I discovered it tonight I have had no success in clearing it up. Any advice?

Thanks!

Deana
