![API support for open data sources
• DOI files
• Interactive querying
– Supported by APIs of Crossref and Europe PMC
– Crossref API has restrictions in the type of queries that can be performed
– Europe PMC API is most flexible, but querying and retrieving citation data cannot be done using a
single API call
– Not supported by the APIs of Semantic Scholar, OCC, COCI, and Wikidata

Wish list forimproving open data sources • Expanding coverage of publications (OCC) • Opening citations (Crossref) • Opening other metadata, e.g. abstracts (Dimensions, Crossref, OCC) • Improving completeness and standardization of metadata (Crossref) • Improve APIs – Add or expand interactive querying (Crossref, Europe PMC, OCC) – Speeding up (OCC) 13
- 12. Outlook • Work togetherwith data providers to improve their APIs • Expand API support • Add support for additional data sources – Microsoft Academic – OpenAIRE – Lens.org • Add support for full-text data sources • Development of web-based version of VOSviewer 14
