TS EN 62656-5

TS EN 62656-5 is the part of the standardized product ontology register and transfer series that addresses how activities and the relations among them are represented through a tabular ontology notation. It places the “parcellized activity model” (PAM) as a specialized use of the parcellized ontology model (POM) defined in Part 1 of the IEC 62656 series.

What the activity model represents

In general technical terms, an activity model is used to describe a whole enterprise or part of one, a collection of services, or a network of interacting events and processes. The model does not treat activities as isolated items only; it also captures their connections, exchanges, and the physical or non-physical entities involved in those exchanges. A tabular ontology representation is intended to keep this information structured, reusable, and suitable for exchange in spreadsheet-based environments.

Technical focus of this part

• Uses the PAM tabular ontology representation.
• Defines a method for representing activities and relations among activities.
• Applies to enterprises, organizations, services, events, and processes that interact.
• Considers the exchange of physical and non-physical entities as part of the modeling context.
• Adapts the general POM framework to activity description.

As a result, the standard is relevant where activity information needs to be expressed in a more structured and interoperable ontology form rather than as free text. In vocabulary, data-exchange, and enterprise information-modeling contexts, keeping terms and relations in a consistent tabular structure helps support alignment across systems. TS EN 62656-5 is the part focused on activity description through this spreadsheet-oriented ontology approach.
