Conf Researchr: A Domain-Specific Content Management System for Managing Large Conference Websites

Authors: Danny M. Groenewegen, Elmer van Chastelet, Max M. de Krieger, Daniel A. A. Pelsmaeker, and Craig Anslow

Published in: OASIcs, Volume 109, Eelco Visser Commemorative Symposium (EVCS 2023)

Abstract
Conferences are great opportunities for sharing research, debating solutions, and networking. For the organizing committee there is a considerable deal of complexity and effort required to provide attendees and organizers with ways to find and manage programs, sessions, papers, tracks, talks, and authors. Eelco Visser found an opportunity to provide an integrated solution to these problems by designing the Conf Researchr conference management system in 2014 using our own domain-specific web programming language WebDSL. In this paper, we highlight the impact Eelco had on conference management, and how Conf Researchr evolved to become the platform of choice for hosting over 900 conference and workshop editions in SIGPLAN and SIGSOFT, among other areas of computer science research.

Eating Your Own Dog Food: WebDSL Case Studies to Improve Academic Workflows

Authors: Danny M. Groenewegen, Elmer van Chastelet, Max M. de Krieger, and Daniel A. A. Pelsmaeker

Published in: OASIcs, Volume 109, Eelco Visser Commemorative Symposium (EVCS 2023)

Abstract
SDF, Stratego and Spoofax provide a platform for development of domain-specific programming languages. On this platform, the WebDSL project started out as a case study in language engineering, and grew into a reliable tool for rapid prototyping and continuous development of web applications. Our team led by Eelco Visser develops and operates several web applications to support academic workflows. EvaTool governs the process of course quality control, importing questionnaire data, and providing lecturers and education directors with a platform to discuss and agree on improvements. WebLab is an online learning management system with a focus on programming education, with support for lab work and digital exams, used by over 40 courses. Conf Researchr is a domain-specific content management system for creating and hosting integrated websites for conferences with multiple co-located events, used by all ACM SIGPLAN and SIGSOFT conferences. MyStudyPlanning is an application for composition of individual study programs by students and verification of those programs by the exam board, used by multiple faculties at the Delft University of Technology. These tools served as practical case studies for applying the research, and ensure the continued development of the underlying platform.

IceDust: Incremental and Eventual Computation of Derived Values in Persistent Object Graphs

Authors: Daco C. Harkes, Danny M. Groenewegen, and Eelco Visser

Published in: LIPIcs, Volume 56, 30th European Conference on Object-Oriented Programming (ECOOP 2016)

Abstract
Derived values are values calculated from base values. They can be expressed in object-oriented languages by means of getters calculating the derived value, and in relational or logic databases by means of (materialized) views. However, switching to a different calculation strategy (for example caching) in object-oriented programming requires invasive code changes, and the databases limit expressiveness by disallowing recursive aggregation. In this paper, we present IceDust, a data modeling language for expressing derived attribute values without committing to a calculation strategy. IceDust provides three strategies for calculating derived values in persistent object graphs: Calculate-on-Read, Calculate-on-Write, and Calculate-Eventually. We have developed a path-based abstract interpretation that provides static dependency analysis to generate code for these strategies. Benchmarks show that different strategies perform better in different scenarios. In addition we have conducted a case study that suggests that derived value calculations of systems used in practice can be expressed in IceDust.
