In the context of the BMBF-funded project ROSI (Reference Implementation for Open Scientometric Indicators), visualisations are being developed and their impact on researchers investigated. For this purpose, only data from open data sources will be collected via persistent identifiers of persons, documents or organisations. Furthermore, a reference implementation based on VIVO will be developed in which various indicators with data from open sources such as Crossref Event Data or Wikidata will be visualized. Interviews and workshops with researchers will be conducted to gather their requirements concerning scientometric data. Findings from the interviews and workshops will be incorporated into the reference implementation in an iterative process. The selection of the indicators, the data aggregation levels and data visualisation types will be addressed. A Registry of Scientometric Data Sources is created as a by-product in which APIs with data relevant for the purposes of scientometrics are captured and made findable. This poster describes the project and presents the current status of the project results. https://tib.eu/rosi-project
