The document proposes a semantic framework for modeling quotes in email conversations. It involves extending the SIOC (Semantically-Interlinked Online Communities) ontology to capture quoting patterns observed in analyzing mailing list archives. Specifically, a new "quotes" ontology is defined to represent quoted text using the "quotes:has_block" property, allowing quoted portions of messages to be explicitly linked back to the original text. This enhanced model allows quotes extracted from email threads to be represented and queried in RDF.
