GROM requires the following:

• Bundler

gem 'grom'

This gem's main function is taking an ntriple data stream and deserialising it into linked Grom::Node objects.

file = File.read('people_members_current.nt')
data_stream = StringIO.new(file)

objects = Grom::Reader.new(data_stream).objects #=> [<#Grom::Node ...>, <#Grom::Node ...>, ...]

Note that ntriple data streams cannot contain a predicate named 'type', as this word is reserved for RDF types.

To clone the repository and set up the dependencies, run the following:
