Declarative languages build on sound theoretical bases to provide attractive frameworks for application development. These languages have been successfully applied to many different real-world situations, ranging from data base management to active networks to software engineering to decision support systems.

New developments in theory and implementation have opened up new application areas. At the same time, applications of declarative languages to novel problems raise numerous interesting research issues. Well-known questions include designing for scalability, language extensions for application deployment, and programming environments. Thus, applications drive the progress in the theory and implementation of declarative systems, and benefit from this progress as well.

PADL is a forum for researchers and practitioners to present original work emphasizing novel applications and implementation techniques for all forms of declarative concepts, including, functional, logic, constraints, etc.

PADL'14 welcomes new ideas and approaches pertaining to applications and implementation of declarative languages, and is not limited to the scope of the past fifteen PADL symposia

In this occasion PADL is co-located, as traditionally, with ACM POPL, which will be held immediately following PADL, January 20-21. The symposium will be held at the US Grant Hotel in San Diego, CA, USA.
