Overview

Splits a Resource into multiple resources of its own class by a given delimiter in its ‘#providedLabel`. The full original resource is retained with the first value from the split label.

Examples:

splitter = SplitProvidedLabelAtDelimiter.new
concept = DPLA::MAP::Concept.new
concept.providedLabel = 'abc; 123'
concept.exactMatch = RDF::URI('http://example.org/alphabet')

results = splitter.enrich_value(concept)

results.map(&:providedLabel)
# => [['abc'], ['123']]

results.map(&:exactMatch)
# => [[#<ActiveTriple::Resource:...>], []]
