In the past year we have seen the release of a huge volume of open bibliographic citation data, thanks primarily to the efforts of the Initiative for Open Citations (I4OC, https://i4oc.org). However, the incomplete coverage of these data is one of the most important issues that the open scholarship community is currently facing. In this paper we present an approach for creating open citation data while supporting journal editors in their task of curating the reference lists contained within articles submitted to them for publication. Our contributions are twofold: (a) a basic workflow that supports editors in the management and correction of bibliographic references, and (b) a tool, called BCite, that creates open citation data compliant with an existing RDF-based citation repository: the OpenCitations Corpus.
