CoPaMo – International Workshop on Collaborative and Participatory Modeling

Co-located with ACM/IEEE MODELS’25 (https://conf.researchr.org/home/models-2025)

October 5-7, 2025

Grand Rapids, MI, USA / Online

We cordially invite you to submit papers to the second edition of the International Workshop on Collaborative and Participatory Modeling (CoPaMo).

Collaboration has become a particularly important topic in model-driven and model-based engineering due to the increasing complexity of systems, which requires a coordinated interplay between diverse stakeholders. However, collaborative modeling cannot be restricted to purely technical concerns and requires support for efficient communication and reducing the threshold to stakeholder participation. Complementary to the technical focus of collaborative modeling, participatory modeling focuses on organizing stakeholders into a purposeful process during which models can be elicited. The synergies between collaborative and participatory modeling are clear and it is high time to investigate them in detail.

This workshop aims to unearth the visceral synergies between collaborative and participatory modeling in a full-day format, entertaining technical presentations, a keynote, and a participatory discussion session.

# Format: online-first hybrid

To ease the logistics of participation, this year’s edition will follow an online-first hybrid format. That is, authors of accepted papers will have the choice to present their works remotely. MODELS will offer separate in-person and online registrations. CoPaMo 2025 welcomes online participants.

# Topics of interest
The topics of interest include, but are not limited to:

- Technical facets of collaborative modeling
- Real-time and conflict-free collaboration, consistency in collaborative MDE/MBE, conflict - management;
- Version control systems and techniques for asynchronous collaboration;
- Multi-paradigm, multi-view, and multi-level aspects of collaboration.
- Organizational and human facets of participatory modeling
- Methods for designing participatory modeling sessions: tools, languages, and facilitation techniques;
- Involving domain experts without modeling experience;
- Use cases and preconditions of participatory modeling: when is participatory modeling suitable?
- Synergies between collaborative and participatory modeling; mixed collaboration models.

# Paper format
We solicit the following types of papers.
- Full research papers (up to 10 pages) reporting on novel scientific contributions,
- Short papers (5 pages), reporting on works in progress, preliminary results, new ideas; and collaborative tools and frameworks.

The page limits include references and appendices.

# Important Dates

July 10, 2025 - Paper submission deadline.
July 31, 2025 - Author notification.
August 7, 2025 - Camera-ready deadline.

# Submission and proceedings

Submit your paper on EasyChair: https://easychair.org/conferences/?conf=copamo2025.
Accepted papers will be published in the MODELS Companion proceedings by IEEE, and on the workshop’s website.
