A diagram is a symbolic representation of information using visualization techniques. Diagrams have been used since prehistoric times on walls of caves, but became more prevalent during the Enlightenment. Sometimes, the technique uses a three-dimensional visualization technique which then become projected onto a two-dimensional surface.

describes inter-related things of interest in a specific domain of knowledge;composed of entity types (which classify the things of interest) and specifies relationships that can exist between instances of those entity types

YAWL (Yet Another Workflow Language) is a workflow language based on workflow patterns. It is supported by a software system that includes an execution engine, a graphical editor and a worklist handler. It is available as open-source software under the LGPL license.

XPDL defines an XML schema for specifying the declarative part of workflow / business process.

NGSI-LD is an information model and API for publishing, querying and subscribing to context information. It is meant to facilitate the open exchange and sharing of structured information between different stakeholders. It is used across application domains such as smart cities, smart industry, smart agriculture, and more generally for the Internet of things, cyber-physical systems, systems of systems and digital twins.
