[Evergreen-general] Setting Up a New Classification Scheme

[Jason Boyer]

Hi Jennifer, there isn’t an interface to manage this yet and while the Angular client’s auto-grid feature will allow you to see the table, you’re not able to add or edit any entries. One reason there’s no interface for it is that one of the required fields is the name of a database procedure to perform the necessary normalization for sorting.

These are the steps you’d need to take to add a new classification scheme today:

Look at the existing call number classification normalization functions to see if one of them is applicable to the new scheme: asset.label_normalizer_generic, asset.label_normalizer_dewey, and asset.label_normalizer_lc. If none of these normalizers will work for the new scheme a new normalizing function will need to be written. (We’ll assume you have to put together an asset.label_normalizer_nlm for now)

Insert a new row into asset.call_number_class:
name                         | normalizer                 | field
National Library of Medicine | asset.label_normalizer_nlm | 060ab,(other fields / subfields)

Then the opensrf.settings service (at least?) may need to be restarted. I’m not entirely certain about the extent of that.

And then it’s time to test because I’ve not actually done this myself but I don’t believe classification schemes are hard-coded anywhere. :)

I've looked through the official docs and the Evergreen wiki but I haven't been able to find anything that talks about how the classifications schemes are set up or what would be needed to set up a new one.
