Rich semantics supports detailed information organization for the contents of documents, across documents, and even across resources in different modalities. In its strongest form, rich semantics provides highly-structured direct representations. This workshop welcomes papers on new directions for frameworks using such rich information organization. Rich semantics goes beyond simple models for linked data such as those using RDF-based triples and beyond ad hoc ontologies. Rather, rich semantic frameworks may include complex entities, dynamic models, schemas, systems, and descriptive programs.
