This paper introduces the Web Engineering Resources Portal (shortly WEP), as a basic Reference Model and Guide for the Web Engineers. WEP provides a general classification of Web Engineering Resources under technologies, research results and tools. It consists of a Reference Model and a Resources Portal. The objective of WEP Reference Model is to provide a common basic terminology, a technical-oriented classification of WebApps, a specification of WebApps Logical and Physical Architectures, a classification of skills needed in Web Projects and a generic and adaptable Web lifecycle process model. WEP Reference Model provides the framework upon which Web Engineering resources will be classified and presented in WER-Portal. The aim of WER-Portal is to provide several and cross-referenced taxonomies of technologies, research results and tools and to facilitate Web Engineers to comprehend available resources, understand their role and appropriately use them during Development and Operation/...
