Gordon,
First, "Patron Matrix" is not typical Evergreen terminology. That looks
like something that is specific to Evergreen Indiana.
That said, if you want to figure out if a patron can borrow an item,
there is an API call that you can make via OpenSRF:
open-ils.circ.checkout.permit. This call determines if a checkout is
permitted and is part of the two-stage checkout process. (Note that the
two-stage checkout process has mostly been replaced with a single call
to open-ils.circ.checkout.full.)
If you're trying to test if a patron can place a hold or not, placing
the hold is the only way to do that.
There are a few database functions that test various aspects of the hold
and circulation rules, but these are not exposed in any public API.
That said, I'm not sure exactly what you are trying to do, so I am just
guessing. If you can provide more information about what you wish to
achieve, then we might be able to come up with more/better answers for you.
Also, you may want to consider moving this conversation to the
development mailing list.
HtH,
Jason

Hi,
I am a project manager so not particularly technical. We are looking
into how we can enforce the rules of the Patron Matrix
(https://evergreenindiana.org/wp-content/uploads/2015/05/Patron-Matrix.pdf
<https://evergreenindiana.org/wp-content/uploads/2015/05/Patron-Matrix.pdf>)
in our application. Could someone point me in the right direction in
terms of API documentation / strategies to implement blocks as per the
Patron Matrix? I am finding the documentation hard to navigate (possibly
due to not being very technical?).
All responses hugely appreciated
Kind regards,
Gordon
