DOI (Digital Object Identifier)

Introduction

  1. a DOI for each number within the OJ series and for each linguistic version, the DOI suffix is based either on logical references to the publication or on the catalogue number; it is not excluded to have two identifiers according to the dissemination context;
  2. a DOI for an identified document the title of which appears in the table of contents for each linguistic version.

The DOI suffix has to be based on information which is available at the moment of publication and which is not dependent from any kind of deep analysis.
