This publication TIC4.0 2021.1 contains the semantic, dataset roadmap, data model and 25 definitions on the topic of Power Source and Activity. It is a very extensive publication with the aim to . This document explains the context for the application of the definitions, the semantics, dataset roadmap and the data model. To improve the readability of the document, the information included is kept at a high level. However, the reader can analyse the information in much more details by using the links in the document. The detailed information accessible through the links is extensive and give the reader a clear overview (depending on their needs from managers to developers), of the TIC4.0 standards for the cargo handling industry.
These 25 definitions are part of the ongoing work to develop a vocabulary for the cargo handling industry. The total and growing current list of definitions being worked on can be accessed on the digital platform of TIC4.0. The links are provided in the dictionary. The release combines the actual definition This publication release describes the actual definitions and includes them in the TIC4.0 templates with the general approach on how to use this in data models, schemas and JSON formats as examples.

With the definitions and language, any reality (equipment or process) in a port terminal environment can be uniquely described. The vocabulary needs to work for any equipment, process and protocol (digital or human). The typical elements that make up the port terminal activities are cargo handling equipment (any kind of machine within the terminal that performs a job or task), external vehicles (trucks, vessels, trains), terminal infrastructure (berth, yard, gate), or auxiliary elements (energy, light, refuelling…).
...
The work of TIC4.0 is to define the individual entries of the Data Set/Dictionary, focusing on a logical group or theme. In the Data Set/Dictionary the user can see the status of each entry and which entries are published and a link to the definition is provided.
To apply the words in each entry in several digital protocols, a Data Schema is needed. TIC 4.0 will propose one Data Schema for each of the most common protocols, but the Data Schema can be used for any protocol could be used. For the examples, TIC 4.0 usually uses JSON as it is very easy human readableuser friendly and easy to read.
2 Semantic
The semantic combines 6 six basic elements: HEADER, SUBJECT, CONCEPT, OBSERVED PROPERTY, POINT OF MEASUREMENT and VALUE to represent a unique reality.
HEADER identifies the message in origin, (destination), time of reference for the message and unique reference.
SUBJECT (who) is the entity that is doing or being the CONCEPT.
CONCEPT (what is-does) refers always to a particular subject (or subject-subsystem) specifying what the subject is (status) or does (action-event)
OBSERVED PROPERTY (how much) is the magnitude of the concept (status, pieces, length, volume, weight, energy, time, speed, power, duration, acceleration…) represented in the value.
POINT OF MEASUREMENT (where) defines where in place and time (past, present, future) the value representing the concept observed property of the subject is measured and represented.
VALUE is the actual measured result for a specific combination of time of measurement + subject + concept + observed property + point of measurement. The same value can be represented in several units.
The combination of a SUBJECT with multiple combinations of CONCEPTs, OBSERVED PROPERTies and POINT OF MEASUREMENTs give us a unique meaning of a VALUE.
TIC 4.0 aims to define each of these elements.
...
The Data Set is just the database that contains the well-defined by TIC 4.0 list of data (a piece of reality). We represent this data as a combination of subject+concept+observed property, indicating what possible point of measurements and units are valid.
Data: represented in a flat format
Subject: including subject and sub-subjects
Concept: represented by the concept id
Observed Property (Obs Property)
Point of Measurement (PoM)
Value: possible units to be used for the data representation
Link to the definition: hyperlink to the definition template for each component of the data.
Workflow status (status): what is the status within the TIC 4.0 workflow
Version: expressed in “year.version”
Release: date of realising in “yyyymmdd” format
Short Description: for a fast to help provide a high-level understanding of the data. This short definition description is not enough to fully understand the data.
We For this reason we have divided it the data by main subjects (CHE, TOS, Terminals…) and topics to make surfing easier. Also, the digiDigi-book has a very powerful tool to search for keywords.
The data set can be found in https://tic40.atlassian.net/l/c/FxmCAXxr
Road Map
This data set is increasing in growing size very fast quickly as the representation of the reality is complex. The data set contains not only the published data definition (status = published) but also the ones data in draft status to allow the developers to have a broad visibility and to program and prepare in advance the systemsas much visibility as possible to allow program and preparation of the systems in advance.
The Data set will always match the data model, both of them are each one is just a different representation of the same data (flat vs. structured).
2021.1 Dataset
Within the 2021.1 release TIC 4.0 has focused its effort in on two topics of the Dataset for CHE: Activity and PowerSouce. Activity represents the “status” of the CHE and the PowerSource contains the most relevant data of from any kind of powersource (engine) of the CHE.
...
For the digital formating of the semantic and data set we need a data model to structure the data and a data schema to define the details of the content like the validity of the format or the type of data (boolean, entire, real etc.), what 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 TIC 4.0 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 many subjects identical but with different metadata (id or name or location or…) can be sent in the same message. (1 message with several CHEs or one CHE with several spreaders).
The CONCEPT'smetadata defines “what is” and the CONCEPT“what does”. Both are flat (no hierarchy, no arrays) and we can use as many as necessary. Also, two concepts can be combined with “and” or “or” creating a new concept that in fact is the condition that makes both true. 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 magnitudes of the CONCEPT, are flat (no hierarchy) and can be used as many times as necessary per CONCEPT.
For each OBSERVED PROPERTies an array created by the combination of the different POINT OF MEASUREMENTs in time (actual, estimated, etc), place (input, iinput, ioutput, output), timestamps and the differents Units will give an array (a list) of VALUEs. The array could be as long as necessary per 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 MEASUREMENTs that need to be represented.
Below is one example of one message with 3 subjects (1 subject and 2 sub-subjects), 3 metadata per subject, 2 different concepts that apply to several subjects and 3 observed properties that affect all the subjects.
...
The bricks that build the data set are made by individual elements that are defined by TIC 4.0 following a template. The below is an example of the TIC4.0 conceptsconcept template.
...
Subjects
The subject definitions are referring to the TIC4.0 semantic: SUBJECT (who) is the entity that is doing or being the CONCEPT.
In this 2021.1 we use a complete set of draft definitions subjects for CHE (physical devices) that are listed in the https://tic40.atlassian.net/l/c/FxmCAXxr but only 3 are completely ready for publication.

...
The 2021.1 release includes the most relevant concepts for a CHE activity that represents the most important states, i.e. if it is “on”, “off”, “working” or “idle”. But these can be used for any subject including a process. Besides these “status” concepts a relevant set of definitions has been publish published for the PowerSource (engine) also valid for any kind of “engine” regardless of the type. We invite you to have a look at the https://tic40.atlassian.net/l/c/FxmCAXxr or if you prefer at the CHE JSON data model 2021.1 that includes the road map 2021 for any CHE.
