@inproceedings {aghaee2013live, title = {Live Mashup Tools: Challenges and Opportunities}, year = {2013}, month = {May}, address = {San Francisco, CA, USA}, abstract = {Live programming is a programming style in which the repetitive task of compiling and running the software being programmed is managed automatically. This style can be a helpful practice in End-User Development (EUD) where the non-professional end-users are to be supported through techniques and tools that empower them to create or modify software artifacts. Mashups {\textemdash} a form of lightweight Web applications composing reusable content and functionalities available on the Web {\textemdash} are a popular target for EUD activities on the Web. EUD for mashups is enabled by intuitive composition environments, called mashup tools. In this paper, we introduce live mashup tools, a new class of mashup tools based on the live programming style. We give a comprehensive definition and classification of live mashup tools, giving examples of how well existing tools fit in this category and discuss open research challenges and opportunities.}, keywords = {live programming, NaturalMash, Web mashups}, doi = {10.1109/LIVE.2013.6617338}, author = {Saeed Aghaee and Cesare Pautasso} }
