GDPRtEXT uses the ELI ontology to define various sections within the GDPR such
as Chapter, Section, Article, Point, and SubPoint. These are defined using
`eli:LegalResourceSubdivision`. The connection between these subdivisions is
defined using properties extended from `eli:has_part` and `eli:is_part_of`.
```

The concepts within GDPR are expressed using `skos:Concept`. They are related
to the text within the GDPR where they are defined or mentioned using
`rdfs:isDefinedBy` property. 
```
    &lt;owl:Class rdf:about=&quot;http://purl.org/adaptcentre/openscience/ontologies/GDPRtEXT#Consent&quot;&gt;
        &lt;rdfs:subClassOf rdf:resource=&quot;http://www.w3.org/2004/02/skos/core#Concept&quot;/&gt;
        &lt;rdfs:comment xml:lang=&quot;en&quot;&gt;Consent in the context of the GDPR refers to ...&lt;/rdfs:comment&gt;
        &lt;rdfs:isDefinedBy rdf:resource=&quot;http://purl.org/adaptcentre/openscience/resources/GDPRtEXT#article4-11&quot;/&gt;
        &lt;rdfs:isDefinedBy rdf:resource=&quot;http://purl.org/adaptcentre/openscience/resources/GDPRtEXT#article6-1&quot;/&gt;
        &lt;rdfs:isDefinedBy rdf:resource=&quot;http://purl.org/adaptcentre/openscience/resources/GDPRtEXT#recital32&quot;/&gt;
        &lt;rdfs:isDefinedBy rdf:resource=&quot;http://purl.org/adaptcentre/openscience/resources/GDPRtEXT#recital40&quot;/&gt;
        &lt;rdfs:label&gt;Consent&lt;/rdfs:label&gt;
    &lt;/owl:Class&gt;
```

The connection between different concepts is
represented using the property [involves](#involves) defined by GDPRtEXT.
```
    &lt;owl:Class rdf:about=&quot;http://purl.org/adaptcentre/openscience/ontologies/GDPRtEXT#DataMinimisation&quot;&gt;
        &lt;rdfs:subClassOf rdf:resource=&quot;http://purl.org/adaptcentre/openscience/ontologies/GDPRtEXT#Principle&quot;/&gt;
        &lt;involves rdf:resource=&quot;http://purl.org/adaptcentre/openscience/ontologies/GDPRtEXT#AccurateCollection&quot;/&gt;
        &lt;involves rdf:resource=&quot;http://purl.org/adaptcentre/openscience/ontologies/GDPRtEXT#ExplicitPurpose&quot;/&gt;
        &lt;involves rdf:resource=&quot;http://purl.org/adaptcentre/openscience/ontologies/GDPRtEXT#PersonalData&quot;/&gt;
        &lt;involves rdf:resource=&quot;http://purl.org/adaptcentre/openscience/ontologies/GDPRtEXT#Processing&quot;/&gt;
        &lt;involves rdf:resource=&quot;http://purl.org/adaptcentre/openscience/ontologies/GDPRtEXT#SpecifiedPurpose&quot;/&gt;
        &lt;rdfs:comment xml:lang=&quot;en&quot;&gt;The principle of data minimisation states that personal data must be adequate, relevant and limited to what is necessary in relation to the purposes for which they are processed.&lt;/rdfs:comment&gt;
        &lt;rdfs:isDefinedBy rdf:resource=&quot;http://purl.org/adaptcentre/openscience/resources/GDPRtEXT#article5-1-c&quot;/&gt;
        &lt;rdfs:isDefinedBy rdf:resource=&quot;http://purl.org/adaptcentre/openscience/resources/GDPRtEXT#recital39&quot;/&gt;
        &lt;rdfs:label&gt;Principle of Data Minimisation&lt;/rdfs:label&gt;
    &lt;/owl:Class&gt;
```

The hierarchy of `skos:Concept` within GDPRtEXT is used to reflect the relation
of concepts in two different ways. One is to represent subclasses as narrower
types of the concept, such as [data](#Data) and [personal data](#PersonalData).
The other is to use subclasses to group related concepts together, as is the 
case with [obligation](#Obligation) and [DPO obligation](#DPOObligation) and
[monitor compliance](#MonitorCompliance) where 'monitor compliance' is also
an [activity](#Activity) as well as refers to [compliance](#Compliance).

There are over 200+ concepts defined within this ontology referring to the GDPR.
These were modelled through a reading of the GDPR text and using terms and 
concepts referred to within the text. The terms are not meant to be instantiated,
though in some cases, such as for personal data, it may be beneficial.
The aim of the ontology is to provide a way to refer to these concepts and use
them in other additional work.

The following diagrams (displayed in two parts for clarity) were generated using
Protege and display the classes in GDPRtEXT modeled from an analysis of the GDPR.
