This book constitutes the refereed proceedings of the
First International Rapid Mashup Challenge, RMC 2015, held on June 23, 2015, in
Rotterdam, The Netherlands, in conjunction with the 15th International Conference
on Web Engineering, ICWE 2015.





The 2015 edition of the challenge is the first
installment of a series of challenges that aim to engage researchers and
practitioners in a competition for the best mashup approach. The 6 thoroughly
reviewed contributions contained in this volume are extended versions of the
initial proposals that served the authors to express their interest to
participate in the challenge. The initial proposals have been used by the
challenge organizers to select participants based on the interestingness and
maturity of the proposals.
