There's a slow-burning discussion on taxonomic concepts on Github that I am half participating in. As seems inevitable in any discussion of taxonomy, there's a lot of floundering about given that there's lots of jargon - much of it used in different ways by different people - and people are coming at the problem from different perspectives. In one sense, taxonomy is pretty straightforward.

Donald Hobern drew my attention to nice the way iNaturalist displays taxonomic splits: In this example, observations identified as Rhipidura fuliginosa are being split into Rhipidura fuliginosa and Rhipidura albiscapa . This immediately reminds me of the idea which keeps circulating around, namely using version control tools to manage taxonomic classification.

Just a quick not to make a link between David Shorthouse's post about taxonomic consensus and distributed version control (Taxonomic Consensus as Software Creation), and Galen Charlton's article in The Code4Lib Journal (Distributed Version Control and Library Metadata). Some interesting food for thought here. Both mention Git.
