One set will take an ontology file, extract the labels for Google translation, and create RDF for those translated labels. The other set does the same for a properties file.

A utility that reads an RDF file, builds a model, sorts all of the URIs that have
|
|
labels, and associates those URIs with the labels in a supplied text file, one line
|
|
per label.
|
|
|
|
These labels are assigned the language specified on the command line, and the
|
|
resulting RDF statements are sent to standard output as N3.
|
|
|
|
On the command line provide the path to the RDF file, the path to the labels file,
|
|
and the desired language/locale. E.g.:
|
|
|
|
label_inserter.rb ../../vivo-core-1.5-annotations.rdf labels.file es_ES
