What is it?

This gem provides Ruby client connectivity to Datacite's Metadata store (MDS). The MDS is a service for data publishers to mint DOIs and register associated metadata. It is aimed mainly at scientific and research data publishers. This gem allows for simple and seamless interaction with the MDS service.

Installation

Add this line to your application's Gemfile:

gem 'datacite_mds'

And then execute:

$ bundle

Or install it yourself as:

$ gem install datacite_mds

Usage

create an Mds object (explicit authorization)

mds = Datacite::Mds.new authorize: {usr: "joe bloggs", pwd: "password"}

create an Mds object (implicit authorization via DATACITE_USR, DATACITE_PWD environment variables)

mds = Datacite::Mds.new 

create an Mds object for testing (implicit authorization)

mds = Datacite::Mds.new testing: true    

resolve a DOI

res = mds.resolve '10.5072/existing-doi'
p res # => <Net::HTTPOK 200 OK readbody=true

upload metadata

res = mds. File.read('metadata.xml')
p res # => <Net::HTTPCreated 201 Created readbody=true>

mint a DOI

res = mds.mint '10.5072/non-existing-doi', 'http://ora.ox.ac.uk/objects/uuid:<an-existing-uuid>'
p res # => <Net::HTTPCreated 201 Created readbody=true> 

update dataset for existing DOI

res = mds.mint '10.5072/existing-doi', 'http://ora.ox.ac.uk/objects/uuid:<new-uuid>'    
p res # => <Net::HTTPCreated 201 Created readbody=true> 

get metadata for existing DOI

res = mds. '10.5072/existing-doi'
p res # => <Net::HTTPOK 200 OK readbody=true
p res.body # shows the xml metadata

Tests

Minitest is used for testing. To run all tests, you must set the DATACITE_USR, DATACITE_PWD environment variables and then:

$ rake test

Note: Some of the tests use DOIs and URLs issued to the Bodleian Libraries and can be accessed only by using the Bodleian datacentre authorisation credentials. It is recommended that you substitute these constant variables' values in the test file, with your own datacentre's DOIs and URLs.
