nyu_marcxml_export_plugin, v.3.0.2.2

An Archives Space plugin to export resource and item level records to marcxml

Scope

This plugin modifies and extends the default marcxml mapping. It also contains extra fields.

Behavior

The way to override the default functionality is to find the method/model where the functionality has been coded and copy that to the plugin and change it to implement the new requirements. This plugin also contains additional classes to extend the marcxml mapping.

Plugin Organization

• plugin_info.txt: a file that contains the plugin version and the config invocation in ArchivesSpace to add the plugin. This is used in deployment to automatically add this plugin to the ASpace config file
• build.xml: xml file for the application build
• backend:
  • plugin_init.rb: file that contains calls to the files being used in the plugin
  • model:
    • nyu_custom_model_marc21.rb: This file overrides and extends the default behavior of the marc21 model.This contains changes to the default marc mappings.
  • lib:
    • aspace_extensions.rb: extension of the marc export helper. It adds top containers to the marcxml. It uses the solr schema to grab the top containers which speeds up the function considerably. This interacts with the json models of all the data models in ASpace.
    • marc_custom_field_serialize.rb: the core of the extra plugin marc mapping functionality lives here. It references a custom class that is defined in the file below.
    • nyu_custom_tag.rb: custom class created for this pllugin. It creates data structures for the marc fields and subfields.
    • nyu_custom_serializer_marc21.rb: had to tweak the default functionality of this code since the plugin was adding extra controlfields. The default functionality had hardcoded the controlfields
  • spec:
    • export_custom_marc_spec.rb: contains tests that checked a version of the marc export. Needs to be updated to reflect current output
