“…MetaEdit+ represents a class of modeling tools that gained substantial industrial adoption, and could benefit from a real-time collaborative framework such as lowkey. The two exceptions are TGRL [42] and the MONDO framework [19]. TGRL is a tool for requirements modeling in a collaborative way.…”

“…Thus, CRDT cannot efficiently accommodate models as firstclass citizens. Existing solutions either (i) focus exclusively on textual modeling and reduce collaboration to textual primitives which are well-supported by current CRDT frameworks [42]; or (ii) work on models of limited complexity and do not support proper graph semantics at the data level [20]. As a consequence, current CRDT-based techniques fall short of supporting intricate modeling scenarios, such as multi-level modeling [3].…”

The need for real-time collaborative solutions in model-driven engineering has been increasing over the past years. Conflict-free replicated data types (CRDT) provide scalable and robust replication mechanisms that align well with the requirements of real-time collaborative environments. In this paper, we propose a real-time collaborative multi-level modeling framework to support advanced modeling scenarios, built on a collection of custom CRDTs, specifically tailored for the needs of modeling environments. We demonstrate the benefits of the framework through an illustrative modeling case and compare it with other state-of-the-art modeling frameworks.

“…Cooper, 2017). There are popular extensions available in IDEs that can assist with real‐time coding to produce clean code (Saini & Mussbacher, 2021). For example, RStudio has recently adopted a vertical line in the source code editor to indicate an 80‐character line limit.…”

Dracon: An Open-Hardware Based Platform for Single-Chip Low-Cost Reconfigurable IoT Devices

et al. 2022

The development of devices for the Internet of Things (IoT) requires the rapid prototyping of different hardware configurations. In this paper, a modular hardware platform allowing to prototype, test and even implement IoT appliances on low-cost reconfigurable devices is presented. The proposed platform, named Dracon, includes a Z80-clone microprocessor, up to 64 KB of RAM, and 256 inputs/outputs (I/Os). These I/Os can be used to connect additional co-processors within the same FPGA, external co-processors, communications modules, sensors and actuators. Dracon also includes as default peripherals a UART for programming and accessing the microprocessor, a Real Time Clock, and an Interrupt Timer. The use of an 8-bit microprocessor allows the use of the internal memory of the reconfigurable device as program memory, thereby, enabling the implementation of a complete IoT device within a single low-cost chip. Indeed, results using a Spartan 7 FPGA show that it is possible to implement Dracon with only 1515 6-input LUTs while operating at a maximum frequency of 80 MHz, which results in a better trade-off in terms of area and performance than other less powerful and less versatile alternatives in the literature. Moreover, the presented platform allows the development of embedded software applications independently of the selected FPGA device, enabling rapid prototyping and implementations on devices from different manufacturers.
