Collection of common properties for use in schemas
This schema provides a collection of common properties for use in other
schemas. It can be imported directly into other linkml schemas, or
any of its individual property definitions can be used by their
URI as vocabulary components or definitions (e.g., dlprops:name
identified by this URI).
Class definitions are only included insofar as they define ranges for particular property slots.
Slot names use the plural form whenever they are directly declared as
"multivalued" in this schema, otherwise the singular form is used for
the slot name. The slot_uri always uses the singular form.
Every property declared here is mapped to standard/established vocabularies.
The schema definition is available as

Classes
| Class | Description |
|---|---|
| Annotation | A tag/value pair with the semantics of OWL Annotation. |
| AttributeSpecification | An attribute is conceptually a thing, but it requires no dedicated identifier (pid). Instead, it is linked to a Thing via its attributes slot and declares a predicate on the nature of the relationship. |
| 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 pid 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. |
| Property | An RDF property, a Thing used to define a predicate, for example in a Statement. |
| 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). |
