A utility that reads an RDF file, builds a model, sorts all of the URIs that have
|
||
|
|
display_names, and produces a file of those display_names, one per line. The idea is that this
|
||
|
|
file could be translated, and the result could be put into RDF by display_name_inserter.rb
|
||
|
|
|
||
|
|
This required the RDF.rb gem: sudo gem install rdf
|
||
|
|
|
||
|
|
On the command line provide the path to the RDF file. E.g.:
|
||
|
|
|
||
|
|
display_name_stripper.rb '../../PropertyConfig.n3'
|
||
|
