Call for Participation
2nd workshop on
Relationships and Associations in Object-Oriented Languages RAOOL'09
co-located with ECOOP'09



Relationships and roles are important concepts used in many areas of
computer science (e.g., conceptual modeling, database systems,ontology)
but are not "first-class" constructs in modern programming languages. In
current object-oriented languages, programmers are forced to implement
relationships or roles "by hand" (using pointers and collections)
leading to a disconnect between models and implementations. This
disconnect causes numerous problems across the software engineering life
cycle: most importantly, implementations become cumbersome because
relationships are represented by several code fragments, scattered
throughout the application code, resulting in code fragility. Since
current mainstream languages lack appropriate support for heap querying,
programmers are further burdened with crafting code to query
relationships and check their consistency. As software systems grow and
become increasingly complex this disconnect causes problems not only for
implementers but also for code maintainers.

In response, a growing number of researchers in the software community
are investigating adding first-class support for relationships and heap
queries to current programming languages. Interest in first-class
support for such constructs is not limited to programming language
research. Program analysis, for instance, could benefit from the
decreased use of pointers and transparent persistence could benefit from
explicit queries.

In this workshop, we plan to gather researchers in the programming
language community who are working on relationship-based systems to
share their research and to discuss the future of relationship-based
constructs in programming languages. We are interested in input from
members of the programming language community but also in input from
members of related areas (e.g. databases, model-driven development) and
domains (e.g., program analysis, orthogonal persistence, type systems)
who are using relationships. Some particular areas of interest are:

- relationship-based programming languages
- using libraries/frameworks to support relationships
- first-class queries
- database integration
- serialization or persistence using relationships
- system and framework design using relationships
- understanding or visualizing programs
- ownership and related techniques
- dynamic analysis of relationship usage
