Conference Description

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.

Topics of interest include:

  • Innovative applications of declarative languages.
  • Declarative domain-specific languages and applications.
  • Practical applications of theoretical results.
  • New language developments and their impact on applications.
  • Declarative languages and Software Engineering.
  • Evaluation of implementation techniques on practical applications.
  • Practical experiences and industrial applications.
  • Novel uses of declarative languages in the classroom.
  • Practical extensions such as constraint-based, probabilistic, and reactive languages.

PADL'12 welcomes new ideas and approaches pertaining to applications and implementation of declarative languages, and is not limited to the scope of the past thirteen PADL symposia (past proceedings can be found in Springer Verlag LNCS, numbers 1551, 1753, 1990, 2257, 2562, 3057, 3350, 3819, 4354, 4902, 5418, 5937 and 6539).

In this occasion PADL is co-located, as traditionally, with ACM POPL, which will be held immediately following PADL, January 25-27. The symposium will be held in Philadelphia, Pennsylvania, USA. Previous PADLs were held in Austin, Texas (2011), Madrid, Spain (2010), Savannah, Georgia, USA (2009), San Francisco, California, USA (2008), Nice, France (2007), Charleston (2006), Long Beach (2005), Dallas (2004), New Orleans (2003), Portland (2002), Las Vegas (2001), Boston (2000), and San Antonio (1999).

Submission Guidelines

Authors should submit an electronic copy of the full paper in PDF using the Springer LNCS format. The submission will be done through EasyChair conference system. If electronic submission is impossible, please contact the program chairs for information on how to submit hard copies.

All submissions must be original work written in English. Submissions must be unpublished and not submitted for publication elsewhere. Work that already appeared in unpublished or informally published workshops proceedings may be submitted.

Each submission must include on its first page the paper title; authors, affiliations and contact emails; abstract; and three to four keywords. The keywords will be used to assist us in selecting appropriate reviewers for the paper.

PADL'12 will accept both technical and application papers:

Technical Papers

Technical papers must describe original, previously unpublished research results. Technical papers must not exceed 15 pages in Springer LNCS format.

Application Papers

Application papers are a mechanism to present important practical applications of declarative languages that occur in industry or in areas of research other than Computer Science. Application papers will be published in the Springer-Verlag conference proceedings, and will be presented in a separate session. Application papers are expected to describe complex and/or real-world applications that rely on an innovative use of declarative languages. Application descriptions, engineering solutions and real-world experiences (both positive and negative) are solicited. The limit for application papers is 6 pages in Springer LNCS format.

newLNCS Proceedings

The proceedings of PADL'12 appear as volume number 7149 of Springer Verlag's LNCS series.

The proceedings are also available online.
