Abstract

Developing Web content for mobile devices is more challenging than developing for the desktop Web. Compared to desktop Web clients, mobile Web devices come in a much wider range of shapes, sizes and capabilities. The mobile Web developer relies upon accurate device descriptions in order to dynamically adapt content to suit the client.

Furthermore, there are different situations where it is needed to group different kind of devices to create categories, families, hierarchies or clusters of devices. There are in the market different propietary solutions for structuring devices, that rely on propietary mechanisms, which makes it hard to portate different groupings and device structures between different device description solutions.

The MWI-DDWG is charterted to the simplification and standardization of issues around device description for content adaptation. As a result it is needed to define standard and portable mechanisms for describing device structures and groupings. This Note is devoted to different technical approaches for solving those issues. Additionally, this Note defines an standard API that can be used in the development of applications that exploit device structure information for adaptation or other purposes.

This Note should be read in conjunction with:

  • the Delivery Context Ontology [DDWG-Ontology] document.
  • the DDR-API W3C Recommendation
