revision
type: DatatypeProperty
range: string
description: The property "vaem:revision" is a property intended for general use as the name implies.

name
type: DatatypeProperty
range: string
description: The property "vaem:name" is intended for general use. In many cases "rdfs:label" could be used give names to resources. In the case where compliance with a specific naming rule is needed, "vaem:name" allows a resource to carry a name that is used in more specific contexts.

has viewpoint
type: ObjectProperty
sub property of: has dimension
description: The property "vaem:hasViewpoint" is used to denote how a set of resources, or an individual resource, is relevant to a context of use. The term "viewpoint" is adopted from the ISO RM-ODP specifications and its more recent use in enterprise architecture descriptions. In VAEM, the property is used as a dimension for characterizing an ontology graph. The property is an "rdf:Property" to allow both scalar and object values

ViewpointDimension
type: Class
subclass of: Domain
description: Viewpoint is used to denote how a set of resources, or an individual resource, is relevant to a context of use. The term "viewpoint" is adopted from the ISO RM-ODP specifications and its more recent use in enterprise architecture descriptions. The RM-ODP introducesd the concept of viewpoint to describe a system from a particular set of concerns. RM-ODP defines five viewpoints. Together they provide a complete description of a system: enterprise viewpoint, information viewpoint, computational viewpoint, engineering viewpoint, and technology viewpoint. In VAEM, "Viewpoint" is used as a dimension for characterizing an ontology graph. The viewpoints of an ontology may not always correpsond directly to those of a system but the idea of describing a subject area of interest from distinct viewpoints is still relevant. A viewpoint can be further distinguished by "aspects". For example the "information viewpoint" of an application can be partitioned into separate graphs for the "security", "operational" and"data retention" aspects.

has steward
type: ObjectProperty
description: A property that is used to refer to a "Steward", that is, the party or role that is responsible for maintaining an asset, in the case of VAEM, an ontology graph.

turtle file URL
type: DatatypeProperty
range: anyURI
description: The property "vaem:turtleFileURL" is used to provide a link to the location of the ontology's turtle file

has aspect
type: ObjectProperty
sub property of: has dimension
description: The property "vaem:hasAspect" is used to distinguish among sets of features of a domain or subject area. The term is borrowed from "aspect-oriented" programming, where it is used to separate concerns. An ontology may be characterized by this dimension so as to parition features that are orthogonal. For example, in a systems ontology we can distinguish aspects for "structure", "function", "behavior" and "interface". The property is an "rdf:Property" to allow both scalar and object values

Aspect Dimension
type: Class
subclass of: Domain
description: Aspect is used to distinguish among sets of features of a domain or subject area. The term is borrowed from "aspect-oriented" programming, where it is used to separate concerns. An ontology may be characterized by this dimension so as to parition features that are orthogonal. For example, in a systems ontology there may be aspects for "structure", "function", "behavior" and "interface" or "interoperability". A viewpoint can be distinguished by "aspects". For example the "information viewpoint" of an application can be partitioned into separate graphs for the "security", "operational" and"data retention" aspects.

namespace prefix
type: DatatypeProperty
range: string
description: The property "vaem:namespacePrefix" specifes a short handle or label for the URI of an Ontology. Multiple graphs can define statements for resources in the same Ontololgy namespace. For example, a foundation level graph with the base URI of "http://www.somesite.com/1.0/schema/OurOntology" may define general concepts for "OurOntology". Another graph with the base URI "http://www.somesite.com/1.0/schema/level2/OurOntology" may add more specific details to the same "OurOntology". Each of these two graphs would carry the same value for "vaem:namespacePrefix", for this example, perhaps, "ourOntology"

has discipline
type: ObjectProperty
sub property of: has dimension
description: The property "vaem:hasDiscipline" is used to indicate relevance of a set of resources, or a resource itself, to a specific discipline of work or study. Examples of disciplines in the engineering domain are electrical engineering, mechanical engineering and, in the financial domain, risk assessment, investment analysis. In VAEM, the property is used as a dimension for characterizing an ontology graph. The property is an "rdf:Property" to allow both scalar and object values

Discipline Dimension
type: Class
subclass of: Domain
description: A discipline is a specific area of work or study. Examples of disciplines in the engineering domain are electrical engineering, mechanical engineering and, in the financial domain, risk assessment, investment analysis. In VAEM, discipline is used as a dimension for characterizing an ontology graph

has identifier
type: ObjectProperty
description: The property "vaemhasIdentifier" is intended for general use as a means to specifiy a unique reference to something. This is an object property that is a sub-property of "vame:id"

specificity
type: DatatypeProperty
range: nonNegativeInteger
description: The property "vaem:specificity" is intended to specify the level of detail of an ontology. The values that can be set for this property are restriced to an integer from 1 to 5. An ontology at level 1 has concepts of more general applicability than one at level 5. By having graphs at different levels of specificity it is possible to support greater modularity for selective imports

has domain
type: ObjectProperty
sub property of: has dimension
description: The property "vaem:hasDomain" is used to specify how a set of resources, or an individual resource is grounded in a domain, that is, a subject area of interest. Examples of domains are "enterprise", "process", "organization" and "system". In VAEM, the property is used as a dimension for characterizing an ontology graph. The property is an "rdf:Property" to allow both scalar and object values

Domain Dimension
type: Class
subclass of: Domain
description: A domain is a subject area of interest. Examples of domains are "enterprise", "process", "organization" and "system". In VAEM, "Domain" is used as a dimension for characterizing an ontology graph

namespace
type: DatatypeProperty
range: anyURI
description: The property "vaem:namespace" is the onotlogy URI with which a graph is primarily associated. The intent is to allow multiple graphs to define statements for resources in the same Ontology namespace. For example, a foundation level graph with the base URI of "http://www.somesite.com/1.0/schema/OurOntology" may define general concepts for "OurOntology". Another graph with the base URI "http://www.somesite.com/1.0/schema/level2/OurOntology" may add more specific details to the same "OurOntology". Each of these two graphs would carry the same value for "vaem:namespace", that is, "http://www.somesite.com/schema/OurOntology". In other words, an ontology URI is the URI associated with the resources of a controlled namespace. On the other hand the graph URIs (the base URIs) identify the graphs that hold resources that make up an ontology

file prefix
type: DatatypeProperty
range: string
description: The property "vaem:filePrefix" is for specifying a preferred file prefix for a graph. For example a schema graph may be given the file prefix "SCHEMA" followed by an underscore "_".

reifiable by
type: ObjectProperty
description: To express how statements in a model can be reifiable, this property is used to explicitly associate a property with a user-defined sub-class of "rdf:Statement". A recommended way of using this is to declare the properties that share the same reification constructs as sub-properties of a parent property that carries the "vaem:reifiableBy" property. The parent property should be of type "rdf:Property" so that it can have both datatype and object properties as sub-properties. By this means use and transformations of a model can be understood through a fully specified metamodel. "vaem:reifiableBy" is rangeless in order to comply with OWL DL semantics. Its range would have been rdfs:Class in order to refer to "rdf:Statement" sub-classes

has dimension
