Delivery Context Access for Mobile Browsing

The usage of context data to facilitate adaptive applications is gaining widespread prominence. We describe an architecture for adaptive Web applications specially suited for mobile devices. This approach is based on an ongoing standardization effort within World Wide Web Consortium (W3C) for client side device context access. The specification, delivery context: interfaces (DCI) is intended to be used as an access mechanism for context consumers. We augment this approach by providing additional interfaces for context providers towards data provisioning to DCI and usage of a dynamic profile generation mechanism that relies on DCI for data serialization. This complements approaches such as utilizing user agent profiles used in server side adaptation. We also provide details of a proof-of-concept implementation for DCI along with two adaptive applications and outline our future plans for this paper
