20th International Workshop on OCL and Textual Modeling
June 26, 2020, Bergen, Norway

Co-located with
STAF 2020 - Software Technologies: Applications and Foundations

Modeling started out with UML and its precursors as a graphical notation.
Such visual representations enable direct intuitive capturing of reality,
but they have weaknesses: for example, detailed visual representations
bear the risk of becoming overcrowded faster than textual models and some
of the visual features lack the level of precision required to create
complete and unambiguous specifications. These weaknesses of 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.

## Topics of interest

Topics of interest include (but are not limited to):

- Mappings between textual modeling languages and other languages/formalisms
- Mathematical models and/or formal semantics for textual modeling languages
- 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
- Libraries, templates and patterns for textual modeling languages
- Tools that support textual modeling languages (e.g., verification of
OCL formulae, runtime monitoring of invariants)
- Model-driven security using textual modeling languages
- 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
- Innovative textual modeling tools
- Comparison, evaluation and integration of modeling languages
- Correlation between modeling languages and modeling tasks

We particularly encourage submissions describing:
1. Applications and industrial case studies of textual modeling, with
a focus on both strengths and shortcomings.
2. Test suites and benchmark collections for evaluating textual
modeling tools.
3. Evolution and perspectives of textual modeling languages, such as
its compatibility and integration with other languages.

## Submissions

Four types of submissions will be considered:

* Presentation only submission (not included in the workshop
proceedings), e.g., for already published work. Authors should
submit a short (1 page) abstract of their presentation.
* Short papers (between 5 and 7 pages) describing new ideas or
position papers.
* Tool papers (between 5 and 7 pages) describing tools supporting
textual modeling tools
* Full papers (between 10 and 14 pages).

All submissions should follow the Springer LNCS format guidelines
( and should be
uploaded to EasyChair (

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 CEUR (
