Classes
| Class | Description |
|---|---|
| AttributeSpecification | An attribute is conceptually a thing, but it requires no dedicated identifier (id). Instead, it is linked to a Thing via its attributes slot and declares a predicate on the nature of the relationship. |
| Identifier | An identifier is a label that uniquely identifies an item in a particular context. Some identifiers are globally unique. All identifiers are unique within their individual scope. |
| ComputedIdentifier | An identifier that has been derived from information on the identified entity. |
| Checksum | A Checksum is a value that allows to check the integrity of the contents of a file. Even small changes to the content of the file will change its checksum. This class allows the results of a variety of checksum and cryptographic message digest algorithms to be represented. |
| IssuedIdentifier | An identifier that was issued by a particular agent with a notation that has no (or an undefined) relation to the nature of the identified entity. |
| DOI | Digital Object Identifier (DOI; ISO 26324), an identifier system governed by the DOI Foundation, where individual identifiers are issued by one of several registration agencies. |
| Relationship | An association class for characterizing the relation between two things with the role(s) the object had with respect to the subject. A relationship is always between two things only, but can be annotated with multiple roles (for example, a person having both an author role with respect to a dataset, and also being the person who is legally responsible contact for it). |
| Statement | An RDF statement that links a predicate (a Property) with an object (a Thing) to the subject to form a triple. A Statement is used to qualify a relation to a Thing referenced by its identifier. For specifying a qualified relation to an attribute that has no dedicated identifier, use an AttributeSpecification. |
| Thing | The most basic, identifiable item. In addition to the slots that are common between a Thing and an AttributeSpecification (see ThingMixin), two additional slots are provided. The id slot takes the required identifier for a Thing. The relation slot allows for the inline specification of other Thing instances. Such a relation is unqualified (and symmetric), and should be further characterized via a Statement (see characterized_by). From a schema perspective, the relation slots allows for building self-contained, structured documents (e.g., a JSON object) with arbitrarily complex information on a Thing. |
| Activity | An activity is something that occurs over a period of time and acts upon or with entities; it may include consuming, processing, transforming, modifying, relocating, using, or generating entities. |
| Agent | Something that bears some form of responsibility for an activity taking place, for the existence of an entity, or for another agent's activity. |
| SoftwareAgent | Running software. |
| Entity | A physical, digital, conceptual, or other kind of thing with some fixed aspects; entities may be real or imaginary. |
| Publication | A document that is the output of a publishing process. This can printed or electronic work offered for distribution, and may have been made available by a publisher. |
| InstantaneousEvent | A moment of a transition from one particular state of the world to another. |
| Location | A location can be an identifiable geographic place (ISO 19112), but it can also be a non-geographic place such as a directory, row, or column. As such, there are numerous ways in which location can be expressed, such as by a coordinate, address, landmark, and so forth. |
| Property | An RDF property, a Thing used to define a predicate, for example in a Statement. |
| Role | A role is the function of a resource or agent with respect to a subject, in the context of resource attribution or relationships. |
| ValueSpecification | A Thing that is a value of some kind. This class can be used to describe an outcome of a measurement, a factual value or constant, or other qualitative or quantitative information with an associated identifier. If no identifier is available, an AttributeSpecification can be used within the context of an associated Thing (attributes). |
| ThingMixin | Mix-in with the common interface of Thing and AttributeSpecification. This interface enables type specifications (rdf:type) for things and attributes via a type designator slot to indicate specialized schema classes for validation where a slot's range is too generic. A thing or attribute can be further describe with statements on qualified relations to other things (characterized_by), or inline attributes (attributes). A set of mappings slots enables the alignment for arbitrary external schemas and terminologies. |
| ValueSpecificationMixin | Mix-in for a (structured) value specification. Two slots are provided to define a (literal) value (value) and its type (range). |
