Digital Collections

The Ohio State University Libraries digital object repository based on Fedora/Hydra/Sufia.

Prerequisites

The following dependencies must be installed to run this application.

Ruby 2.3.1 with Bundler
Redis, a key-value store
ImageMagick with JPEG-2000 support
FITS 0.8.x (0.8.5 is known to be good)
LibreOffice
Ghostscript (may be required if not bundled with LibreOffice)
Handle.Net Software 8.1.1
PhantomJS >= 1.8.1 (only needed for feature tests)

While not required, macOS users may find the Homebrew package manager helpful to manage dependency installation.

Note that this project should run on GNU/Linux, macOS, or other Unix-like operating systems. It has not been tested on Microsoft Windows.

Ruby

First, you'll need a working Ruby installation. You can install this via your operating system's package manager, but we recommend using a dedicated Ruby version manager such as chruby, RVM, or rbenv.

We recommend Ruby 2.3.1.

Characterization

Download a copy of FITS (see above to pick a known working version) and unpack it somewhere on your machine.
Mark fits.sh as executable: chmod a+x fits.sh
Run fits.sh -h from the command line and see a help message to ensure FITS is properly installed

Derivatives

Install LibreOffice. If which soffice returns a path, you're done. Otherwise, add the full path to soffice to the .env file (see below). On macOS, soffice is inside LibreOffice.app. Your path may look like //LibreOffice.app/Contents/MacOS/

You may also require ghostscript if it does not come with your compiled version LibreOffice. brew install ghostscript should resolve the dependency on a Mac.

Handle System

Download a copy of the Handle.Net Software (see above to pick a known working version) and unpack it somewhere on your machine.

Tests

To run RSpec feature tests, you will need PhantomJS >= 1.8.1. On macOS, install via Homebrew:

$ brew install phantomjs

For other platforms, see the PhantomJS download page

Production

When deploying to production, be sure to install Monit on any server used to run Sidekiq workers. You will need to create a monitored service for Sidekiq (see config/monit.example) and allow the Rails user to execute monit via sudo without a password. For example:

rails ALL=(ALL) NOPASSWD: /usr/bin/monit
Defaults:rails !requiretty

Production installations should also set the paths for the minter state file, derivatives directory, and uploads directory to appropraite locations with environment variables:

MINTER_STATEFILE="/path/to/minter-state"
DERIVATIVES_PATH="/path/to/derivatives"
UPLOAD_PATH="/path/to/uploads"

These paths should be shared between all production hosts, for example an NFS share available to a front-end server and back-end Sidekiq host.

Installation

Change to the project directory, be sure the correct version of Ruby is in use, and install all gem dependencies:

$ cd purple
$ ruby -v
$ bundle install

Create the development SQLite database and load the schema:

$ bundle exec rake db:migrate

Create a .env file to hold environment variables for this application. This file will be loaded each time the server is started. See .env.example for details.

$ cp .env.example .env

Specifically, you should set:

FITS_PATH - the full file system path to fits.sh
LIBREOFFICE_PATH - the full path to soffice (if needed)
HDL_HOME - path to directory containing the Handle.Net software

Next, you will need to start Solr and Fedora manually to download and configure their dependencies. Run each of the commands below, wait for the service to start, then use Ctrl-C to close the program.

$ solr_wrapper -d solr/config/ --collection_name hydra-development
$ fcrepo_wrapper -p 8984

Subdirectory installation

If you are planning to run the application in a subdirectory, (i.e. at http://example.com/myapp/) set the RAILS_RELATIVE_URL_ROOT environment variable to the relative path. (ex: RAILS_RELATIVE_URL_ROOT='/myapp')

Use

Start Redis, Solr, Fedora, and Sidekiq using a single foreman command:

$ bundle exec foreman start

Then, in a separate terminal window, start the Rails development server:

$ bundle exec rails server

You can now navigate to the application at http://localhost:3000. You can also access Solr at http://localhost:8983/ and Fedora at http://localhost:8984/.

Creating initial admin user and role

An administrative user needs to be created to access all the features of DC. First, visit http://localhost:3000/users/sign_in and create an account. Next, open a Rails console to set up admin access:

$ bundle exec rails c
> u = User.find_by_user_key("your_user@example.com")
> u.admin = true
> u.save

Development

Tests are run using RSpec:

$ bundle exec rspec  #to run all tests
$ bundle exec rspec spec/path/to/my_spec.rb  #run a single spec file

Before committing, be sure your code matches the project style guide using rubocop.

$ bundle exec rubocop

Dependencies added to the project should comply with certain license requirements. Specifically, including or linking against GPL licensed code should be avoided. Check the licenses of installed dependencies using license_finder:

$ bundle exec license_finder --decisions-file=.dependency_decisions.yml
