Title:
Automating UI Generation by Model Composition

Abstract:
Automated user-interface generation environments have been criticized for
their failure to deliver rich and powerful interactive applications. To
specify more powerful systems, designers need multiple, specialized
modeling notations. The model composition problem is concerned with
automatically deriving powerful, correct, and efficient user interfaces
from multiple models specified in different notations. Solutions balance
the advantages of separating code generation into specialized code
generators with deep, model-specific knowledge against the correctness
and efficiency obstacles that result from such separation. We present a
solution that maximizes the advantages of separating code generation.
In our approach, highly specialized, model-specific code generators
synthesize run-time modules from individual models. We address the
correctness and efficiency obstacles by formalizing composition
mechanisms that code generators may assume and that are guaranteed by a
run-time infrastructure. The mechanisms operate to support run-time
module composition as conjunctions in the sense defined by Zave and Jackson.
