NLA Accession Reports plugin

Introduces extra Accession reports, including:

• Valuations Required
• Valuations Completed
• Workplan Development

And adds a 'Download as CSV' button to Accession browse and search screens.

Installing it

To install, just activate the plugin in your config/config.rb file by including an entry such as:

 # If you have other plugins loaded, just add 'nla_accession_reports' to
 # the list
 AppConfig[:plugins] = ['local', 'other_plugins', 'nla_accession_reports']

And then clone the nla_accession_reports repository into your ArchivesSpace plugins directory. For example:

 cd /path/to/your/archivesspace/plugins
 git clone https://github.com/hudmol/nla_accession_reports.git nla_accession_reports
