OCL 2015 Ottawa

15th International Workshop on
OCL and Textual Modeling

co-located with
Models 2015 Ottawa

Call for OCL Workshop Papers

Modeling started out with UML and its precursors as a graphical notation. Such visual representations enable direct intuitive capturing of reality, but some of their features are difficult to formalize and lack the level of precision required to create complete and unambiguous specifications. Limitations of the graphical notations encouraged the development of text-based modeling languages that either integrate with or replace graphical notations for modeling. Typical examples of such languages are OCL, textual MOF, Epsilon, and Alloy. Textual modeling languages have their roots in formal language paradigms like logic, programming and databases.

The goal of this workshop is to create a forum where researchers and practitioners interested in building models using OCL or other kinds of textual languages can directly interact, report advances, share results, identify tools for language development, and discuss appropriate standards. In particular, the workshop will encourage discussions for achieving synergy from different modeling language concepts and modeling language use. The close interaction will enable researchers and practitioners to identify common interests and options for potential cooperation.

Plain text version of the CFP

Topics of interest include (but are not limited to)

  • Mappings between textual modeling languages and other languages/formalisms
  • Algorithms, evaluation strategies and optimizations in the context of textual modeling languages for
    • validation, verification, and testing,
    • model transformation and code generation,
    • meta-modeling and DSLs, and
    • query and constraint specifications
  • Alternative graphical/textual notations for textual modeling languages
  • Evolution, transformation and simplification of textual modeling expressions
  • Libraries, templates and patterns for textual modeling languages
  • Tools that support textual modeling languages (e.g., verification of OCL formulae, runtime monitoring of invariants)
  • Complexity results for textual modeling languages
  • Quality models and benchmarks for comparing and evaluating textual modeling tools and algorithms
  • Successful applications of textual modeling languages
  • Case studies on industrial applications of textual modeling languages
  • Experience reports
    • usage of textual modeling languages and tools in complex domains,
    • usability of textual modeling languages and tools for end-users
  • Empirical studies about the benefits and drawbacks of textual modeling languages
  • Innovative textual modeling tools
  • Comparison, evaluation and integration of modeling languages
  • Correlation between modeling languages and modeling tasks
This year, we particularly encourage submissions describing tools that support - in a very broad sense - textual modeling languages (if you have implemented OCL.js to run OCL in a web browser, this is the right workshop to present your work) as well as textual model transformations.


The workshop will be organized as a part of MODELS 2015 Conference in Ottawa, Canada. It continues the series of OCL workshops held at UML/MODELS conferences: York (2000), Toronto (2001), San Francisco (2003), Lisbon (2004), Montego Bay (2005), Genova (2006), Nashville (2007), Toulouse (2008), Denver (2009), Oslo (2010), Zurich (2011, at the TOOLs conference), 2012 in Innsbruck, 2013 in Miami, and 2014 in Valencia, Spain. Similar to its predecessors, the workshop addresses both people from academia and industry. The aim is to provide a forum for addressing integration of OCL and other textual modeling languages, as well as tools for textual modeling, and for disseminating good practice and discussing the new requirements for textual modeling.

Workshop Format

The workshop will include short (about 15 min) presentations, parallel sessions of working groups, and sum-up discussions.


Three types of papers will be considered:
  • short papers (between 6 and 8 pages) describing ideas,
  • tool papers (between 6 and 8 pages), and
  • full papers (between 12 and 16 pages)
in LNCS format. Submissions should be uploaded to EasyChair (https://easychair.org/conferences/?conf=ocl20150). The program committee will review the submissions (minimum 2 reviews per paper, usually 3 reviews) and select papers according to their relevance and interest for discussions that will take place at the workshop. Accepted papers will be published online in a pre-conference edition of CEUR (http://www.ceur-ws.org).
