Datacite Ruby Client

This is a Ruby client for interfacing with the DataCite REST API. https://support.datacite.org/docs/api

Installation

Add this line to your application's Gemfile:

gem 'datacite'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install datacite

Usage

Initialize the client

client = Datacite::Client.new(username: "foo",
                              password: "bar",
                              host: "api.test.datacite.org")

Create a Draft DOI

result = client.register_doi(prefix: '10.0001', suffix: 'bc123df4567')

result.either(
  -> response { response },
  -> response { raise("Something went wrong", response.status) }
)

Auto-generated DOI's

result = client.autogenerate_doi(prefix: '10.0001')

result.either(
  -> response { response.doi },
  -> response { raise("Something went wrong", response.status) }
)

Update DOI's

# See https://support.datacite.org/reference/dois-2#put_dois-id for the attributes
attributes = {
  relatedIdentifiers: [
    {
      relatedIdentifier: "https://doi.org/10.xxxx/xxxxx",
      relatedIdentifierType: "DOI",
      relationType: "References",
      resourceTypeGeneral: "Dataset"
    }
  ]
}
result = client.update(id: '10.0001/bc123df4567', attributes: attributes)

result.either(
  -> response { response.doi },
  -> response { raise("Something went wrong", response.status) }
)

Determine if a DOI exists

result = client.exists?(id: '10.0001/bc123df4567')

result.either(
  -> response { response },
  -> response { raise("Something went wrong", response.status) }
)

Get metadata for a DOI

result = client.metadata(id: '10.0001/bc123df4567')

result.either(
  -> response { response },
  -> response { raise("Something went wrong", response.status) }
)

Working with Cocina

Validating

This gem provides a method for mapping and validating a Cocina::Models::DRO object to a DataCite request based on the DataCite JSON Schema (v4.6), without sending any data to the DataCite API:

cocina_object = Cocina::Models::DRO.new(...)
validator = Datacite::Validators::CocinaValidator.new(cocina_object:)
puts validator.errors.join(', ') unless validator.valid?

NOTE: A Datacite request payload can be validated without first translating from Cocina if you build the request manually or use your own metadata mapping library, e.g.:

datacite_attributes = { ... }
validator = Datacite::Validators::AttributesValidator.new(attributes: datacite_attributes)
puts validator.errors.join(', ') unless validator.valid?

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
