3.12.6 Note
This document identifies properties that are considered essential for adaptation of content in the mobile Web. Its intended use is to define a baseline vocabulary for implementations of the Device Description Repository (DDR). The vocabulary makes reference to the UWA ontology for the Web delivery context [UWA-Ontology].
The vocabulary defined in this document is not intended to represent an exhaustive set of properties for content adaptation. DDR Implementations that require additional properties are free to make use of additional vocabularies. The process of creating a new vocabulary can be modelled on the process described in this document. Implementors are encouraged to make use of the UWA ontology. Where necessary, the ontology can be extended.
Implementors of DDR solutions that are intended to support content adaptation for mobile Web-enabled devices should, at a minimum, support the DDR Core Vocabulary as defined in this document.
This document is maintained by the MWI DDWG and arrangements will be made to assign a maintainer after the closure of the DDWG.
A public questionnaire was launched to request proposals for inclusion in the core vocabulary, with the following data being obtained for each proposal:
Description: A brief description of the proposed property.
Type: The data type associated with the property.
Justification: An argument put forward to justify the property being part of the core vocabulary. This should explain why the proposed property is essential for basic adaptation of typical Web content, in the context of mobile Web-enabled devices.
Measurement: A explanation of how this property is evaluated, suggesting where appropriate the units of measurement.
This is a list of the properties in the DDR Core Vocabulary. Data types are as defined in [XSD-Part2].
Bindings to the UWA Ontology will be finalized in a later version of the document, those suggested here are for discussion.
Note:
Unlike the UWA Ontology, properties of the Core Vocabulary are not bound to particular aspects of the Delivery Context. Use of the term "display" in several property names is intended to refer to any aspect that can display content, or the Delivery Context as a whole, and is not intended specifically to refer to the aspect of "display" or "screen".
