Allinson Flex - A Flexible Machine-readable Metadata Modeling Implementation

This library implements the M3 specifications found in Houndstooth for Hyrax and other Samvera repository systems. It is able to read an M3 schema along with a profile YAML file and provides a graphical interface for editing the classes, contexts, mappings and properties found with in. It then provides hooks to the various pieces of Hyrax and similar Rails based systems to in order to assign contexts to Admin Sets, create and modify works and have all the properties of that work defined dynamically by users during run time. Work Types must exists in code (there is a work type generator), but all properties within can be edited dynamically by the library and are stored as data.

Overview/intro to flex graphic Note that Flexible Metadata for FileSets and Collections is currently not supported.

Installing

Install Generator

Add this line to your application's Gemfile:

gem 'allinson_flex', git: 'https://github.com/samvera-labs/allinson_flex.git'

And then execute:

$ bundle install
$ rails generate allinson_flex:install
$ rails db:migrate

AllinsonFlex uses webpacker and React JS (via the react-rails gem).

Please run the following if they are not already installed in your application. Note: If running a docker container, these need to be installed outside of the container in order to find the github ssh links.

$ rails webpacker:install
$ rails webpacker:install:react
$ rails generate react:install

Add to app/assets/stylesheets/application.css

 *= require allinson_flex/application

and to app/assets/javascripts/application.js

//= require allinson_flex/application

Set up profiles and classes

Open the app in a browser and navigate to the Hyrax Dashboard > Metadata Profiles and click Import Profile. You can select the example profile in config/metadata_profile/hyrax.yaml

Create work types

The work type installer can run over existing work models or generate new ones.

Add or modify all existing work types, based on Hyrax curation concerns or Dynamic Shemas:

$ rails generate allinson_flex:works

To run the generator against specific models, pass the command a model_name argument like:

$ rails generate allinson_flex:works Image

You can pass it multiple arguments for mulitple models, like:

$ rails generate allinson_flex:works Image Book GenericWork

Accept the overwrite when requested:

Overwrite /app/samvera/hyrax-webapp/app/views/hyrax/base/_attribute_rows.html.erb? (enter "h" for help) [Ynaqdhm]

You must restart rails after generating work classes.

Dedication

From the beginning of the Samvera community to her sudden passing in 2020, Julie Allinson (@geekscruff) was a strong presence in the Samvera community. Always ready to lend a hand or to share knowledge, she embodied so much of what makes this community work. This effort, the last big project she was involved in, was the culmination not just of her time as a developer but the combination of her work as a metadata specialist. It was the evolution of dog biscuits, her work in the m3 group and several other projects she had lead or been involved in. She was an incredible bright star and we name this gem in remembrance of her.
