A quality model for web components

Web components improve Internet applications, empowering end-user development with encapsulation and interoperability. Public repositories contain a variety of web components implementing GUI elements, system components for mashup development and wrappers of popular web services. The distribution of this technology through public repositories has fostered a growing interest in quality metrics for web components, highlighting the absence of unified approach. This paper presents a reference model and evaluation framework for measuring the quality of web components. Preliminary results of an experimentation framework provide insights for comparing standard metrics with custom metrics based on curated user-perceived quality and data extracted from public repositories.
