8Enormous quantities of biodiversity data are being made available online, but much of this 9data remains isolated in their own silos. One approach to breaking these silos is to map local, 10 often database-specific identifiers to shared global identifiers. This mapping can then be used 11to construct a knowledge graph, where entities such as taxa, publications, people, places, 12 specimens, sequences, and institutions are all part of a single, shared knowledge space. Moti-13 vated by the 2018 GBIF Ebbe Nielsen Challenge I explore the feasibility of constructing a 14 "biodiversity knowledge graph" for the Australian fauna. These steps involved in constructing 15 the graph are described, and examples its application are discussed. A web interface to the 16 knowledge graph (called "Ozymandias") is available at https://ozymandias-17 demo.herokuapp.com. 18 19
