Add Public Copy Notes to MARC export when items requested

[Jason Stephenson]

We've had a request to add public copy notes to the 852 subfield z when items are exported via MARC export.

We'll also probably want to add these to the marcxml-full SuperCat and UnAPI exports as well.

[Jason Stephenson (jstephenson)]

I have pushed a branch to the working repository for this feature: user/dyrcona/lp2045440-marc-export-public-copy-notes (https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/dyrcona/lp2045440-marc-export-public-copy-notes).

If we decide to add this to SuperCat/UnAPI, then that should be done under the Aegis of another bug. That's my opinion as of today and is subject to change depending on community feedback.

I am removing the pullrequest tag for now. I want to also add public copy tags to the code. I'll do so in an additional commit.

[Jason Stephenson (jstephenson)]

The branch now has two commits and was rebased on main.

The first commit adds public copy notes to the marc_export program as described above.

The second commit adds public copy tags. The copy tags are distinguishable from copy notes, because the copy tags have the tag type label prepended to them in the 852 subfield z.

There are release notes and tips on testing this new feature in the commit messages.

I am taking this one back. I've been asked to add the note titles to 852$z as well as the note values.

This came up after our first time using it in production.

[Jason Stephenson (jstephenson)]

The code has been modified to add the asset.copy_note titles to the public note entries in subfield z. If the title is not empty it gets added in the same way as the copy tag type, i.e. prepended to the value with a colon and a space, ": ".

The branch was also rebased on the latest master and force pushed to the working repository.

I'm taking this one back to investigate a potential bug with pulling out the notes that have empty titles. They don't seem to be showing up.

I'll double check the extraction of copy tags as well because they use similar logic.

[Jason Stephenson (jstephenson)]

We have determined that the issue reported in comment #6 has nothing to do with empty titles. marc_export grabs those just fine with this branch applied.

It turns out that the issue has to do with our procedures for updating changed records with the discovery layer. We send a file every 10 minutes of updated bib ids, i.e. those that have been edited, had circulations, etc. The discovery then uses SuperCat to retrieve the updated record with item information. SuperCat does not match marc_export when export items in the 852. Several fields are missing.

I plan to add copy tags and copy notes to SuperCat item export as a part of this bug's branch.

I will open another bug for other "missing" 852 fields.

[Jason Stephenson (jstephenson)]

Well, I discovered that Evergeen does send copy notes in the SuperCat feed when items are requested. It looks like the discovery layer needs to be modified to read them. (I also erroneously thought that SuperCat sends the information in a 852 tag, but it adds its own XML to the end of the MARC. I guess I had forgotten about the different format.)

SuperCat does not send copy tags, and if we decide that is important, I'll open a new bug for that.

It also looks like some of the other "missing" information isn't missing, either. The discovery layer just needs code to be able to read it and put it in its own copy of the MARC 852.

I am satisfied that the code for this feature is working as intended. I'll remove the assignment and add the pullrequest tag.

Sorry for the noise/confusion. I'll blame it on the impending holidays and seasonal colds. :)

[Jason Stephenson (jstephenson)]

I have taken this bug back and removed the pullrequest tag for now. We're having internal discussions about changing the order that notes and tags are exported and adding the copy tag url field to the 852$u.

[Jason Stephenson (jstephenson)]

The sum of the feature consists of the top 3 commits in user/dyrcona/lp2045440-marc-export-public-copy-notes working branch (https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/dyrcona/lp2045440-marc-export-public-copy-notes). The branch has been rebased on main as of the time of this comment.

CW MARS has been using this in production for a couple or weeks now with no ill effects.
