• Further investigations are needed on which level of granularity we want the software contributor roles to be.
• If we decide on the few roles from codemeta we need to describe them and probably establish a hierarchy to enable future roles to be added at the correct place
• one idea would be to have only one role with the possibility to add a label, which specifies the role. This is being the case for http://vivoweb.org/ontology/core#ResearcherRole already.
