<Literal xml:lang="en" datatypeIRI="http://www.w3.org/1999/02/22-rdf-syntax-ns#PlainLiteral">The System Ontology defines Systems, Connections between systems, and Connection Points at which systems may be connected. This ontology is then specialized for multiple domains. For example:
- In electric energy:
- power systems consume, produce, store, and exchange electricity;
- power connections are where electricity flows between systems;
- power connection points are plugs, sockets, or power busses.
- In the electricity market:
- players and markets are systems;
- connections are contracts or transactions between two players, or between a player and a market;
- connection points include offers and bids.
Figure below provides an overwiew of the concepts in this ontology:

<IRI>https://w3id.org/seas/Connection</IRI>
<Literal xml:lang="en" datatypeIRI="http://www.w3.org/1999/02/22-rdf-syntax-ns#PlainLiteral">The class of connections between systems.
This class qualifies property `seas:connectedTo`.
A connection describes potential interactions between systems.
For example, a power connection between power systems describes the fact that these systems may exchange electricity.
```
<connection> seas:connectsSystem <electric_vehicle> , <electric_vehicle_service_equipment> .
<electric_vehicle> seas:connectedThrough <connection> .
<electric_vehicle_service_equipment> seas:connectedThrough <connection> .
```
Any two connected systems are connected through a connection. If:
```
<system1> a seas:System .
<system2> a seas:System .
<system1> seas:connectedTo <system2> .
```
then there exists `_:connection` such that:
```
_:connection seas:connectsSystem <system1> , <system2> .
```
A connection can connect more than two systems at the same time.
Figure below illustrates connections of systems:

<Literal xml:lang="en" datatypeIRI="http://www.w3.org/1999/02/22-rdf-syntax-ns#PlainLiteral">The class of connection points of systems, at which they may be connected to other systems.
This class qualifies properties `seas:connectsSystem` and `seas:connectedThrough`.
A connection point belongs to exactly one system.
For example, an electric vehicle service equipment may have three power connection points: two different kinds of plugs that enable to charge electric vehicles, and a three phase power bus connection point to the grid:
```
<electric_vehicle> seas:connectsAt <plug_high_voltage> , <normal_plug> , <three_phase_connection_point> .
```
Any system connected through a connection is connected at one of its connection points to the connection:
if:
```
<system> a seas:System .
<system> seas:connectedThrough <connection> .
<connection> a seas:Connection .
```
then there exists `_:connectionPoint` such that:
```
<system> seas:connectsAt _:connectionPoint .
_:connectionPoint seas:connectsSystemAt <connection> .
```
The system of a connection point that is connected through a connection is itself connected through the connection:. If:
```
<connection> a seas:Connection .
<system> a seas:System .
<connectionPoint> a seas:ConnectionPoint ;
<connectionPoint> seas:connectsSystemThrough <connection> .
```
then it is true that:
```
<connectionPoint> seas:connectionPointOf <system> .
```

<Literal xml:lang="en" datatypeIRI="http://www.w3.org/1999/02/22-rdf-syntax-ns#PlainLiteral">Links a system to a system it is connected to.
Connected systems interact in some way. The exact meaning of _interact_ is defined by sub properties of `seas:connectedTo`.
For example, for the electricity to directly flow between an electric vehicle service equipment and an electric vehicle, then they must be linked by property `seas:exchangesElectricityWith`:
```
seas:exchangesElectricityWith rdfs:subPropertyOf seas:connectedTo .
<electric_vehicle> seas:exchangesElectricityWith <electric_vehicle_service_equipment> .
```
Property `seas:connectedTo` is symmetric:
```
if x seas:connectedTo y, then it is true that y seas:connectedTo x.
```
This property can be qualified using class `seas:Connection`, which connects the two systems.
If there is a connection between several systems, then one may infer these systems are pairwise connected.</Literal>

<Literal xml:lang="en" datatypeIRI="http://www.w3.org/1999/02/22-rdf-syntax-ns#PlainLiteral">Links a system to its super system.
Properties of subsystems somehow contribute to the properties of the super system. The exact meaning of _contribute_ is defined by sub properties of `seas:subSystemOf`.
For example, if a fridge is a subsystem of a kitchen, then its consumption power contributes to the consumption power of the kitchen.
Property `seas:subSystemOf` is functional, and should be asymmetric:
```
if x seas:subSystemOf y1 and x seas:subSystemOf y2, then y1 and y2 refer to the same resource.
if x seas:subSystemOf y, then it can't be the case that y seas:subSystemOf x.
```
The asymmetric aspect of property `seas:subSystemOf` would prevents a system from being its own sub-system. Unfortunately, OWL 2 DL disallow a non-simple property (e.g., a functional property) from being asymmetric, see OWL 2 Syntax section 11.
If it was possible that both the fridge and the kitchen be sub systems of a common super system, say, the house, then the consumption power of the fridge would contribute twice to the consumption power of the house. The functional aspect of property `seas:subSystemOf` prevents this undesired effect.
Due to the open world assumption of RDF, it is not possible to model the closed set of sub systems of a system using property `seas:subSystemOf`.
