mEDRA is the multilingual European Registration Agency of Digital Object Identifiers (DOI). The DOI is a standard for persistently identifying a piece of intellectual property on a digital network and associating it with metadata in a structured, extensible way.
Web services are provided for uploading files to the registry, registering files for DOIs, and retrieving metadata for files in the registry. These services are accessible using mEDRA's SOAP-based API. The mEDRA website is provided in German, English, and Italian.
