Figure 12. Detail from the RDF graph illustrating the contents of a scholarly publication. The data schema employed aligns with the schema shown in Figure 11, tailored to accommodate semantic units. The publication’s content is encapsulated within a dedicated publication item group unit instance through various interconnected semantic units. The publication itself is denoted as an instance of journal article (IAO:0000013). The publication item group unit encompasses multiple item units related to the research activity, interconnected through the *SEMUNIT:hasLinkedSemanticUnit* property. The interconnected hierarchy extends to an investigation (OBI:0000066) instance, resulting in a data set (IAO:0000100) instance with a description (SIO:000136) instance as its part. This description, in turn, has the multicellular organism item unit describing the organism as its part, which has an instance of multicellular organism (UBERON:0000468) as its subject. The blue arrow signifies the representation of the data graph (dark blue box with shadow) by this specific item unit (bordered box in the same color). The ontological layer is constituted by the data graphs of the semantic units, while their semantic-units graphs collectively form the discursive layer. Distinct context units demarcate the reference frames of the publication, research-activity, and research-subject, delineated by is-about statements. For reasons of clarity of presentation, the associated statement units are not shown in the discursive layer.
