1. Introduction
The publication TIC4.0 2025.014 covers the following topics:
...
Looking ahead, the integration of technologies like automation, AI, and IoT will help create "smart yards," where predictive simulations and Digital Twins drive operational improvements. These advancements will enhance interoperability, streamline communication, and optimize resource management, positioning terminals for more agile, data-driven decision-making in the future.
2. Data Model
For the digital formatting of the semantic and Dataset we need a Data Model to structure the data and a Data Schema to define the details of the content, such as the validity of the format, the type of data (Boolean, entire, real etc.), which data is mandatory or could be omitted etc.
...
Following the semantic web standard (subject: object) the model has 3 main components: header, asset description and measurement.
...
SUBJECT creates the hierarchy tree structure (we have sub-subjects) that helps to identify the boundary of the value. The hierarchy is fixed by TIC4.0 for each kind of subject (CHE, TOS, Terminal) and can mix any type of subjects (e.g. machine.process = che.move). The subjects conform to an array defined by the (concept) metadata so various identical subjects but with different metadata (id or name or location or…) can be sent in the same message. (one message with several CHE's or one CHE with several spreaders).
The CONCEPT's metadata defines ‘what is’ and the CONCEPT‘what does’. Both are flat (no hierarchy, no arrays) and as many as necessary can be used. Additionally, two concepts can be combined with ‘and’ or ‘or’ creating a new concept which includes the condition that makes both true. For e.g. ‘hoisting_and_trolleying’ that represents the action of hoisting and trolleying at the same time (both statuses must be true).
OBSERVED PROPERTIES define the ‘magnitude’ of the CONCEPT, are flat (no hierarchy) and can be used as many times as necessary with a CONCEPT.
For each OBSERVED PROPERTY, an array created by the combination of the different POINT OF MEASUREMENTsin time (actual, estimated, etc), place (input, iinput, ioutput, output), timestamps and the different Units will give an array (a list) of VALUEs. The array could be if necessary in each message. The length will depend on the relation between the data frequency and the message frequency and also the amount of different POINT OF MEASUREMENTsthat need to be represented.
...
The Dataset is the content of the Data Model, a flat version without hierarchy or rules. The Dataset is used by humans, but machines need the Data Model and the Data Schema to translate it to a digital format.
