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 give the reader a clear overview (from managers to developers) of the standards.
...
The semantic combines 6 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 “yyymmdd” format
Short Description: for a fast understanding of the data. This short definition is not enough to fully understand the data.
...
The Data set will always match the data model, both of them are just a different representation of the same data (flat vs structured).
2021.1 Dataset
Within 20202021.1 realise TIC 4.0 has focus its effort in 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 any kind of powersource (engine) of the CHE.
...
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 (ie: 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 CONCEPTsmetadata 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. ie “hoisting_and_trolleying” that represents the action of hoisting at trolleying at the same time (both status must be true).
OBSERVED PROPERTies defines the magnitudes of the CONCEPT, is flat (no hierarchy) and we can be used as many 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 needs to be represented.

2021.1 DataModel example
Based on the 20202021.1 Data Set road map an extensive Json example has been complete with all possible data that can be used following the standards. This JSON will be extended as soon as would be required to represent new subjects, concepts or observed properties.
...
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 exmpale of the TIC4.0 concepts.
...
Subjects
The subject definitons definitions are refering referring to the TIC4.0 semantic: SUBJECT (who) is the entity that is doing or being the CONCEPT.
Introduction 2020In this 2021.1 we use a complete set of draft definitions subjects for CHE (ToDo)physical devices) that are listed in the https://tic40.atlassian.net/l/c/FxmCAXxr but only 3 are completely ready for publication.

Concepts
Introduction 2020.1 subjects (ToDo)The 2021.1 release includes the most relevant concepts for a CHE activity that represents the most important states as it is the “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 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.
