SubjectPredicateObject
umbel:hasCharacteristic skos:definition The property umbel:hasCharacteristic is used to assert the relation between a Reference Concept and external properties that may be used in external ontologies to characterize, describe, or provide attributes for data records associated with that concept. It is via this property or its inverse, umbel:isCharacteristicOf, that external data characterizations may be incorporated and modeled within a domain ontology based on the UMBEL vocabulary.
umbel:hasMapping skos:definition This property is used to reify a umbel:isAbout or a umbel:isRelatedTo property to a mapping percentage value, some quantitative metric value, or a qualitative descriptor characterizing the linkage degree or overlap between the two classes, predicates, individuals or datatypes. This value might be calculated from some external utility.
umbel:isAbout skos:definition The property umbel:isAbout is used to assert the relation between a named entity (individual) and a Reference Concept class. umbel:isAbout relates the named entity (individual) to the class through the basis of its subject matter. The relation acknowledges that the scope of the class can not be determined solely by the aggregation or extent of its associated individual entity members, and that the nature of the Reference Concept class may not alone bound or define the individual entity. This property is therefore used to create a topical assertion between an individual and a Reference Concept.
umbel:isCharacteristicOf skos:definition The property umbel:isCharacteristicOf is used to assert the relation between a property and a Reference Concept (or its punned individual) to which it applies. Such properties may be used in external ontologies to characterize, describe, or provide attributes for data records associated with that concept. It is via this property or its inverse, umbel:hasCharacteristic, that external data characterizations may be incorporated and modeled within a domain ontology based on the UMBEL vocabulary.
umbel:isLike skos:definition The property umbel:isLike is used to assert an associative link between similar individuals who may or may not be identical, but are believed to be so. This property is not intended as a general expression of similarity, but rather the likely but uncertain same identity of the two resources being related. This property can and should be changed if the certainty of the sameness of identity is subsequently determined. In general, we may not be able to assert that two individuals are the same based solely on current information on hand. However, there may be quite reasonable bases or methods that the two individuals are likely the same without being one hundred percent sure. umbel:isLike has the semantics of likely identity, but where there is some uncertainty that the two resources indeed refer to the exact same individual with the same identity. Such uncertainty can arise when, for example, common names may be used for different individuals (e.g., John Smith). It is appropriate to use this property when there is strong belief the two resources refer to the same individual with the same identity, but that association can not be asserted at the present time with certitude.
umbel:isRelatedTo skos:definition Check the definition of umbel:isAbout for the definition of this property; isRelatedTo is the inverse property of isAbout.
umbel:relatesToAbstraction skos:definition This predicate relates an external entity to the SuperType (ST) shown. It indicates there is a relationship to the ST of a verifiable nature, but which is undetermined as to strength or a full rdf:type relationship
umbel:relatesToActivity skos:definition This predicate relates an external entity to the SuperType (ST) shown. It indicates there is a relationship to the ST of a verifiable nature, but which is undetermined as to strength or a full rdf:type relationship
http://umbel.org/umbel skos:definition UMBEL (Upper Mapping and Binding Exchange Layer) vocabulary provides a general vocabulary (the UMBEL "vocabulary") of classes and predicates for describing domain ontologies, with the specific aim of promoting interoperability with external datasets and domains.
