ER Demo and Posters
--------------------
The ER Demo and Posters track of ER 2021 offers a vibrant and popular platform for presenting and discussing novel research that addresses any topic related to conceptual modeling and also showcasing prototypes or fully-developed tools systems for developing, communicating, and implementing conceptual models.  Examples for related topics can be found at the conference website: https://www.er2021.org/topics.html.
** Tool Demonstrations (Demos for short) should present innovative software prototypes or full-fledged systems for developing, communicating, and implementing conceptual models. The tools may originate from research initiatives or from the industry. 
** Posters should present visionary ideas and/or innovative research projects for which at least some preliminary results are available. We accept works in a relatively early stage, not necessarily including a complete validation.

Author Guidelines 
------------------
The ER Demo and Posters allows for the following types of submissions:
• Tool Demonstrations regard the exhibition of innovative software prototypes or full-fledged systems for developing, communicating, and implementing conceptual models. The tools may originate from research initiatives or from the industry. Submissions should include a short description including the significance to the conceptual modeling field, the maturity of the work, and if available, a link to a web page or screencast. Demo papers should be of 5-6 pages.
• Posters should present visionary ideas and/or innovative research projects for which at least some preliminary results are available. We accept works in a relatively early stage. Submissions should include a short description including the significance to the conceptual modeling field and the maturity of the work and if available, a link to a web page. Poster papers should be of 5-6 pages.
The papers must adhere to Springer’s LNCS submission formatting guidelines (for details see http://www.springer.de/comp/lncs/authors.html). Manuscripts not submitted in the LNCS style or exceeding the page limit will not be reviewed and hence, they will be automatically rejected. Springer has provided a LaTeX template in Overleaf for your convenience.
A paper submitted to ER Demo and Posters must not be under review in any other conference or journal during the time it is being considered for ER Demo and Posters. The submissions are due in PDF format through the ER 2021 submission system hosted by EasyChair at https://easychair.org/conferences/?conf=er2021 by selecting the ER 2021 Posters and Demos track.
