Here are available various historical documents showing the development of the Documents Entities Texts system underlying Textual Communities.
1. A formal description, dating to 2010, outining the classes and properties as then conceived in an RDF implementation of the DWT (Documents Works Texts) scheme, now renamed Documents Entities Texts (DET). This is the attachment "classes-formaldesc.docx"
2. An implementation of this ontology in RDF form, as an OWL file, for part of Dante's Commedia. This is the attachment "dwt-commedia.owl", again dating to 2010.
