Analysis Layer (CIM)

The goal of the analysis layer metamodels is the definition of a language to describe the high-level features of Context Aware Applications (CAAs) for Ubiquitous Computing Environments (UCEs) defined in [1]. The key concepts of the analysis layer are: the entity, the space and the task.
The relationship among them defines the following paradigm to build analysis layer models.

A CAA for UCE is defined by a set of entities that perform tasks within a space

Therefore, 3 metamodels were defined:

  • The Social metamodel (SoMM) to describe the relationship among entities in terms of social instances (roles, individuals, etc.)
  • The Space metamodel (SpMM) to define the relationship among physical or vitual spaces.
  • The Task metamodel (TaMM) to define how entity characteristics are related to tasks and spaces

The relationship among the models conforming these metamodels is depicted in Figure 2.
