[Koha] Search/List RSS feeds (trigger? add call number?)

Hi Tasha,

I can't answer all your questions, but maybe I can provide a bit of

I think that for the RSS feed on lists the date the record is added to a
list is used. Would that match with what you see?

I think adding the call number to the RSS feed might not be straight
forward, because this information would have to be taken from the items
instead of the record. As there can be many items per record and the
call numbers can vary between the different branches and locations of a
library system, the task of displaying this information in a useful and
nice way is not an easy one. Maybe filing an enhancement request on
bugzilla to discuss this more would be a good first step to discuss this

Hope this helps,

I've taken a look at opac-opensearch.tt and opac-search.pl, in order to under how date limiting is coming in to play, specifically (which dates, what comparison, what fields, etc.).  I do see reference to an 005 date "hack" for Atom, but it seems like only the RSS portions of the code are relevant.  I'd like to determine if I can only ever expect newly added records to be returned, or would/could updated records also be returned?

Therefore, what should trigger a subscriber to receive an update about their list if an item has been updated?  Is it the bib 005, or something else?  I've tried editing a few records in a list I am subscribed to, expecting to get a new email, but I didn't receive a message.  Although this last part may sound confusing, I'm leaving as is, as it may help explain context-I've added the feeds to my Microsoft Outlook, where each matching item shows up as a discrete "email" message in my RSS Feeds folder.
