Hi:

I just published a new post today ‘Robust compute for RDF queries:
Managing fault tolerance in Elixir with supervision trees’.

https://medium.com/@tonyhammond/robust-compute-for-rdf-queries-eb2ad665ef12

The post briefly reviews the process model of Erlang (and Elixir) and
introduces the following abstractions in Elixir: GenServer,
Supervisor, and DynamicSupervisor.

It then develops a demo Elixir application that can be used to query
DBpedia for random resources and save the results into GenServer
processes. It goes on to show how processes can be created under OTP
supervision trees both statically and dynamically and how they are
automatically recreated when they error.

It is this support for fault tolerance and distributed compute that
makes Elxir such a fascinating candidate for semantic web
applications.
