Abstract

Capture and access applications explore the ubiquitous computing paradigm --- that basically consists on populating the environment with computational devices and applications to transparently assist people on their activities --- to support the automatic capture of information on live experiences and generate corresponding documents that can be further stored, retrieved, visualized and extended. Due to their distributed nature, heterogeneity of involved devices and variety of provided functionalities, capture and access applications are hard to build and require software infrastructures and services that help the developer out on his task. This work investigates the building and use of capture and access applications through the development of xINCA, a component-based software infrastructure comprising the most common func-tio-na-li-ties present in such a class of applications. xINCA is an extension of INCA --- a low-level infrastructure that provides communication abstractions for capture and access applications. Complementary, INCA and xINCA provide a simplified model for the development of capture and access applications, concerning design, implementation and reuse aspects. Allied with the StRES storage model, xINCA also plays an important role on the structuring of captured information by using XML and corresponding technologies. (AU)
