Call for Papers

HoWCoM aims to bring together developers of collaborative MDE tools, and the extended modeling community, in order to enable the evaluation of these tools by hands-on experimentation. The results of the evaluations will be used to assess the features, maturity, and challenges of the domain.

Topics of interest

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

  • Real-time synchronous means of collaboration
  • Asynchronous means of collaboration
  • (In)consistency management
  • Advanced conflict visualization and resolution techniques
  • Data-level collaborative techniques
  • Domain-specific collaborative solutions
  • Informal means of collaboration
  • Semantic techniques (versioning, visualization, etc.)
  • Human factors in collaboration


We invite the following three types of submissions.

Case papers (up to 10 pages) elaborating on a collaborative case, and demonstrating its solution via a tool of choice. The description of the case should include a general challenge, and an example scenario of that challenge. Authors of the accepted papers will be invited to give a talk during the morning session, and their tools will be used during the afternoon session. The submitted cases will be used by the organizers to construct the modeling tasks of the afternoon session. Please refer to the specific instructions for case papers below.

Vision papers (5 pages) presenting innovative ideas. Authors of the accepted vision papers will be invited to give a regular talk.

Extended abstracts (1 page) presenting innovative ideas or position statements. Authors of the accepted extended abstracts will be invited for a lightning talk.

All submitted papers must adhere to the IEEE Conference format, and submitted electronically through the HoWCoM EasyChair web page. An Overleaf template is also available. All submissions will be reviewed by at least 3 members of the program committee. Authors of case papers should expect a particularly detailed feedback to allow them to leverage the opportunity the workshop provides to the fullest extent. Case papers and vision papers will be published in the MODELS Companion proceedings. Extended abstracts will not be published. All accepted papers will be available on the workshop website prior to the start of the workshop.

To be published in the proceedings, at least one author of an accepted paper must present their work at the workshop. Additionally, authors of accepted case papers commit to conduct a hands-on session for their tool during the afternoon session.

Case paper specific instructions

Case papers elaborate on a collaborative case, and demonstrate its solution via a tool of choice. The submitted cases will be used by the organizers to construct the modeling tasks of the afternoon hands-on session.

A valid submission consists of two parts: (i) the paper itself, and (ii) the specifics of the hands-on session.

The paper [10 pages + 1 page of references]

  1. Introduction
    • Bird’s eye view of the paper as a whole.
    • Roughly 1-2 paragraphs on the case, tool, and solution, respectively.
  2. Case
    • Description of the problem/application.
      • What is the context and purpose of the case?
      • What is modeled?
    • Focus on the collaborative needs: teams, views, etc.
      • Why is collaboration needed for this case?
    • What variations of the case affect collaboration?
  3. Methodology/tool
    • General description of tool.
      • Name
      • Reference, link to the tool
    • Summary of typical use(s)
      • Real-time, offline collaboration
      • Granularity of collaboration unit
    • Any features specifically interesting for this case?
  4. Solution
    • How is the domain reflected in the tool?
    • How does the tool support the required type of collaboration?
    • Optional: Link to demonstration video
      • Screencast / short video demonstrating how collaboration is facilitated with the tool to perform modeling activities on the case.
      • Maximum length of 5 minutes.
      • Note that if you do not provide a video, reviewers will only evaluate the paper, which should provide enough detail demonstrating the use of the tool for the case.
  5. Hands-on session
    • What insights do you aim to gain from these hands-on experiences?
    • Why are these insights relevant? (Market research, validation of approach, publicity, feedback from user base, etc.)
    • Are there any specific research questions you would like to answer through the participation of the community? What is the novel aspect of the problem that has not been published earlier?
  6. Conclusion
    • Summary of the case and solution
    • Future plans for the tool support
