This protocol is for the research about the availability of Open Citations from Open Journals in Crossref. The goal is to find out how many papers from DOAJ journals are available on Crossref, whether their metadata is available and the origin of their references' DOIs. Our research involves the articles from Open Access journals in DOAJ and their data on Crossref. We scouted the availability of these articles’ reference lists, the presence of IDs such as DOIs and the entities responsible for their specification. This analysis was carried using DOAJ article metadata dump, then modified and enriched thought Crossref’s APIs DOI requests. The data will be further analysed to verify the distribution of the provenance of the articles' DOIs.
