Only the URL is mandatory for DOI registrations at doi.org. If only a URL has been registered for a given DOI, the resolver will redirect to the URL instead of returning the URL as JSON data.
We currently expect all DOIs to return JSON data. We need to check if there is data available and if not, fill in only the URL. In this case, the article and journal titles will not be filled in.
