ISO 24627-3-2021 pdf free download.Language resource management – Comprehensive Annotation Framework (ComAF)- Part 3: Diagrammatic semantic authoring (DSA).
This document specifies how to represent (not visualize) documents (instance data, not data schemas) as graphs. It does not specify how to visualize or operate on document data, but it aims at making documents easier for people to compose and comprehend by allowing for various graph-based flexible user interfaces, possibly incorporating document-visualization practices (see Introduction). In this connection, this document does not specify annotations to existing documents either, but rather it specifies a schema of documents with explicit logical structures.

3.1 hypernode
node which is a graph segment
3.2 segment
referenceable part of a DSA-based document, which is either a graph segment or a data segment (text, image, audio, video, etc.)
3.3 semantic authoring
composition of docunwnts while making their logical structures explicit
4 Specification
Figure 2 illustrates DSA, which is a metamodel (ontology) of graph documents. Each markable (referenceable) part of a DSA-based document is called a segment. Each DSA-based document itself is a segment, too.
A graph segment shall be a labelled directed graph comprising nodes and links. A node shall be a segment and a link shall be a relation between two endnodes (source and destination segments).
A node in a graph segment can be another graph segment. A node which is a graph segment is called a hypernode. So a graph segment can embed other graph segments as hypernodes, which are rarely used in concept maps. Arbitrarily large DSA-based documents can hence be made of small graph segmentswhich are hypernodes of each other.
A data segment can embed smaller data segments as constituents. For instance, a discourse can be a text/audio/video segment embedding sentence utterances as smaller text/audio/video segments, which can further embed still smaller text/audio/video segments such as phrases, and so forth.
DSA is exactly the metamodel in Figure 2, which formally specifies multimodal graph documents involving hypernodes, but does not specify how to visualize or operate on them. The diagrammatic visualizations in Annex A are not part of DSA, they are informative examples. DSA users can adopt any sorts of diagrammatic visualization as far as the logical document structures are made explicit enough to meet their purposes.ISO 24627-3 pdf download.
