CVS Access

The following Eclipse Team Project Set (.psf) will give you access to the higgins.owl source file:

Description

Note: The properties of the Context container itself are attached to special object called ContextObject within the instance data and also described in the ontology.

Classes

1. Attribute
   • 0..N source
   • 0..N timeSpan
   • 0..1 lastModified
   • 0..1 syncConflict
   • 0..1 lastVerifiedFromSource
   • 0..1 lastVerifyAttempt
2. ComplexAttribute (subclass of Attribute)
   • 1..N complexValue
3. ContextObject
   • 0..N hasContextRelationships
4. ContextRelationship
   • 0..N contextURI
5. SimpleAttribute (subclass of Attribute)
   • 1..N simpleValue
6. DigitalSubject (see Digital Subject)
   • 1..1 uniqueIdentifier
   • 0..N timeSpan
   • 0..N attribute
   • 0..N relationship
7. SubjectRelationship
   • 1..1 contextURI
   • 1..1 subjectCUID
8. TimeSpan
   • 0..1 validFrom --if not present, assume validFrom is the beginning of time
   • 0..1 validTo --if not present, assume validTo is the end of time

Subclasses of SimpleAttribute

1. Base64BinarySimpleAttribute
2. NormalizedStringSimpleAttribute
3. StringSimpleAttribute
4. IntegerSimpleAttribute

...we need to create all the rest here (Date*, NonNegativeInteger*, etc. for each of the XML Schema literal types used by OWL)

DataType (literal valued) Properties

1. contextURI - domain(ContextRelationship, SubjectRelationship), range("anyURI")
2. identifier - domain(AttributeStatement), range(xsd:normalizedString)
3. lastModified - domain(AttributeMetadata), range(xsd:dateTime)
4. lastVerifiedFromSource - domain(Attribute), range(xsd:dateTime)
5. lastVerifyAttempt - domain(Attribute), range(xsd:dateTime)
6. simpleMetadata
7. simpleValue - domain(SimpleAttribute)
8. subjectCUID - domain(SubjectRelationship), range(xsd:normalizedString)
9. syncConflict - domain(AttributeMetadata), range(xsd:boolean)
10. uniqueIdentifier - domain(DigitalSubject), range(xsd:normalizedString). Uniquely identifies a DigitalSubject within a context
11. validFrom - domain(TimeSpan), range(xsd:date)
12. validTo - domain(TimeSpan), range(xsd:date)

Sub-Properties of simpleValue

1. base64BinarySimpleValue - domain(Base64SimpleAttribute), range(xsd:base64Binary)
2. integerSimpleValue - domain(IntegerSimpleAttribute), range(xsd:integer)
3. normalizedStringSimpleValue - domain(NormalizedStringSimpleAttribute), range(xsd:normalizedString)
4. stringSimpleValue - domain(StringSimpleAttribute), range(xsd:string)

Object (object valued) Properties

1. attribute - domain(DigitalSubject), range(Attribute)
2. complexValue - domain(ComplexAttribute)
3. contextRelationship - domain(ContextObject), range(ContextRelationship)
4. relationship - domain(DigitalSubject), range(SubjectRelationship)
5. source - domain(Attribute), range(SubjectRelationship). The value is a SubjectRelationship that indicates the authoritative source of the value of this Attribute
6. timeSpan - domain(DigitalSubject, Attribute), range(TimeSpan)
