The Digital Object Identifier (DOI) and the metadata of an article are becoming increasingly important for finding articles quickly, sustainably and accurately. So far we have used the service of DataCite in the “International Journal for Research in Vocational Education and Training (IJRVET)” for this purpose. We are now a member of Crossref, use this service and have re-registered all previously registered DOIs with Crossref. The DOI itself (and our prefix) does not change, but the quality of the metadata has improved. Crossref is specialized in journal articles, while DataCite is more specialized in the registration of data sets. You will notice the difference if you use a literature management software to manage bibliographic data (such as Zotero).
