ORCID implementation in Invenio 1.1

<!--HTML-->We present an extension to the Invenio 1.1 software for semi-automatically harvesting ORCID IDs of users and allowing them to upload publications to their respective ORCID profile. This extension was created in the context of the Join2 initiative, however, it can easily be adapted to other Invenio instances because it is only loosely coupled with Invenio itself. It opens its own local webserver to handle the additional endpoints, and calls Invenio API functions and command line programs to interact with the database. We also present a recommended workflow for successfully harvesting ORCID ID in an institution. The implementation is realised in well-documented Python 2.6 and Go and will be published as Free Software.
