Generating adaptable user interface in SPLE: using delta-oriented programming and interaction flow modeling language

We explore the possibility of including Delta-Oriented Programming (DOP) and Abstract User Interface (AUI) model during product generation in Software Product Line Engineering (SPLE). Previous work showed that DOP is applicable in a SPLE for Web applications albeit User Interface (UI) elements in derived product are still manually created without UI modeling. AUI model is proven to be successful for modeling UI elements for products in SPLE as it can model generic UI elements while still encouraging customization. Therefore, we pick an existing AUI modeling language called Interaction Flow Modeling Language (IFML) to create model of UI elements in a SPLE. We also suggest a new SPLE design that follows DOP and the proposed UI modeling language to generate adaptable UI given product configuration. The process of designing UI for each feature in the product line is based on reference implementation process used in previous work. We hope that the suggested process can solve the current DOP practices limitation in generating UI elements for products in SPLE.
