The core, normative sections of this document are generated automatically
from the ontology itself.
This is the second public Working Draft of a possible future W3C
Recommendation.
The purpose of the Delivery Context Ontology is to provide a formal model
for the delivery context which other specifications can reference
normatively. It is anticipated that work at W3C and in other standards
organisations will reference the ontology when needing formal definitions
associated with the delivery context.
Publication as a Working Draft does not imply endorsement by the W3C
Membership. This is a draft document and may be updated, replaced or
obsoleted by other documents at any time. It is inappropriate to cite this
document as other than work in progress.
1 Introduction
The Delivery
Context Ontology provides a formal model of the characteristics of the
environment in which devices interact with the Web. The delivery context
includes the characteristics of the device, the software used to access the
Web and the network providing the connection among others.
The delivery context is an important source of information that can be
used to adapt
materials from the Web to make them useable on a wide range of different
devices with different capabilities.
1.1 Definition of the Ontology
The ontology is formally specified in OWL[OWL]. The
core, normative sections of this document are generated automatically from
the ontology itself.
The ontology conforms to the OWL-DL
expressivity. This allows it to be used within appropriately written
reasoning systems.
1.1.1 Disjoint Classes
The ontology contains a large number of disjoint classes. OWL-DL requires
explicit definition of each disjoint relationship between classes. The number
of such definitions becomes unmanageably large in ontololgies with a large
number of classes.
Fortunately, there is an alternative mechanism for ensuring that classes
are considered disjoint, without requiring the use of explicit statements.
The mechanism relies on each class including a property that has a unique
value. In this ontology, the property used is called
deliveryContextEntityName. Each class derived from DeliveryContextEntity
includes this property. Each class has a unique value for this property. The
mechanism is referenced in the OWL Guide[OWL] in the
discussion on disjoint classes.
An illustration of the technique appears in [OWL-Test] in the section on Positive
Entailment Test.
| Editorial note: Rhys |
16/8/2007 |
| The initial set of properties
for the ontology were modelled on those in UAProf version 2.
Subsequent discussion has enriched the set of properties currently
defined. A number of groups are in the process of creating sets of
properties for inclusion in the ontology. As a result it is likely
that the properties will change. It's likely that the structure of
the ontology will change in the light of new properties being
added. Readers should not assume that this version represents any
concensus about the content or the structure of the ontology. It
does, however, represent a starting point for discussion. It also
illustrates a number of basic features that such an ontology needs to
provide. It seems likely that the overall structure and approach is
likely to prove appropriate. |
1.2 Reading the Specification
1.2.1.1 Normative and Informative Parts
The normative and informative parts of this specification are identified
by use of labels within various sections. Generally, everything in the
specification is considered to be normative, apart from the examples.
1.2.1.2 Normative Language for Conformance
Requirements
Individual conformance requirements or testable statements are identified
by the use of specific key words. In particular, the key words must,
must not, required, shall, shall not,
should, should not, recommended, may, and
optional in this specification are to be interpreted as described in
[IETF RFC 2119].
1.3 Documentation Conventions
This section describes the structure and layout of the sections that
document the ontology. The delivery context is essentially hierarchical. The
hierarchy is defined in 38 The Paths to the
Characteristics. Despite the hierarchical nature of the delivery
context, every individual property has an unique name.
Properties are associated with classes within the ontology. Each top level
class is documented in its own chapter. Subclasses are documented within the
chapter for their superclass. Cross references within this document link
properties, classes and examples of their use.
1.3.1 Reading the Property Tables
Each class in the ontology is associated with a set of properties. These
properties are defined in tables in the appropriate section of the
specification. Each row in a table defines a single property in terms of a
number of fields. The fields used in these tables are described as
follows:
- Name
This field contains the formal name of the property within the
class.
- Type
This field contains the type of the property. Datatype
properties have types that are not themselves classes.
Examples include xsd:int, xsd:boolean,
xsd:string and xsd:float. Object
properties have types that are classes. Usually these classes
are themselves defined in the ontology.
- Description
This field contains a description of the property.
- Occurs
This field defines the cardinality of the property. The number of
occurences of the property within the class is shown as an expression.
For example, the expression ≥ 0 and ≤ 1 indicates that
a property is optional. It's cardinality is 0 or 1. Similarly, the
expression =1 indicates that a property always occurs
exactly once.
- Value(s)
This field holds values that apply across every instance of a
class.
Some property values are fixed for every instance of a class. Where
this is the case, the value shown in the Value(s) field is prefixed by
the phrase Class Value:. For example, every instance of the
class Meters, which represents a
physical length in meters, has a unitName property with the value
"meter".
Some properties can hold values from a specific, predefined set.
Where this is the case, the value shown in the Value(s) field is
prefixed by the phrase One of:. For example, the Orientation class, which represents the
orientation of features such as displays or cameras, has an orientationValue
property which can take only the values 0,
90, 180 or 270.
- Alternate Names
This field defines the alternative names for the property.
Alternative names might be useful in different programming environments
for consistency with conventions.
1.3.2 Reading the Example Tables
Examples are given for specific classes in the specification. The
associated tables contain one or more example classes, complete with values
for each of their properties. The fields used in these tables are described
as follows:
- Example Instance
This field contains the identification of the instance that
provides the example.
- Property Name
This field contains the formal name of the property whose value is
shown as part of the example.
- Type
This field contains the type of the property in the example.
Datatype properties have types that are not themselves
classes. Examples include xsd:int,
xsd:boolean, xsd:string and
xsd:float. Object properties have types
that are classes. Usually these classes are themselves defined in the
ontology.
- Value(s)
This field contains the value(s) of the property. Where a property
has a cardinality of >1, multiple values may be shown in the
example.
