Abstract

Context-awareness advances have evidenced novel challenges related to context management and context-awareness usability. Most of these problems can be supported through general context attributes, i.e. properties that describe issues of the context itself, what we call meta-context. We can identify similar attributes in a variety of proposals to enhance context-aware systems. However, these attributes are usually managed internally. A common and formal model that describes the significant context attributes, their relationships and semantic axioms helps to separate the meta-context from the context model. Moreover, we propose a specific Semantic-Web-based architecture to manage the meta-context at run-time and offers related functionalities to external context-aware applications.
