In the spirit of release early and release often, here is the first workable version of a biodiversity knowledge graph that I've been working on for Australian animals (for some background on knowledge graphs see Towards a biodiversity knowledge graph now in RIO). The core of this knowledge graph is a classification of animals from the Atlas of Living Australia (ALA) combined with data on taxonomic names and publications from the Australian

Following on from my previous post bemoaning the lack of links between biodiversity data sets, it's worth looking at different ways we can build these links. Specifically, data can be tightly or loosely coupled. Tight coupling Tight coupling uses identifiers. A good example is bibliographic citation, where we state that one reference cites another by linking DOIs.
