Figure 5. Identifier overlap between Wikidata (WD), OTT, and GloBI.

Figure 5

This Venn Diagram shows the number of overlapping external identifiers that can be found in one of three databases. Only 207,958 external IDs can be found in all three. These consisted of 22,637 WoRMS links, 71,980 NCBI links, 103,300 GBIF links and 10,040 IF links. Over two million IDs are only known to one of the three databases. OTT contains more than half of the external IDs in Wikidata and in GloBI, but neither contain half of the external IDs in OTT. Mapping Wikidata to GloBI matched 65.2% of the external IDs in GloBI.
