compactDatasetIris method

Implementation

IriCompactionResult compactDatasetIris(
    List<RdfGraph> allGraphs, RdfDataset dataset, String? baseUri) {
  final iriCompactionInputTriples = <Triple>[];
  for (final graph in allGraphs) {
    iriCompactionInputTriples.addAll(graph.triples);
  }

  // Include graph names in prefix compaction by adding them as synthetic triples
  // This ensures graph name IRIs can also be compacted with appropriate prefixes
  for (final namedGraph in dataset.namedGraphs) {
    // Add a synthetic triple with the graph name as subject
    // This allows the IRI compaction to analyze and generate prefixes for graph names
    iriCompactionInputTriples.add(Triple(
