Exon is a tool used to register the items (machines, screens, lasers, 48 ports switches) you may have at home or in your hackerspace. it provides a hybrid API and stores the data in ETS/DETS tables. Last night, I released v0.0.3 which brings a few adjustments in the JSON part of the protocol and warns if you try to register two items with the same name. Feel free to write a client for it in your favourite language, I wrote a spec sheet for this purpose.
