Research Areas

Since software engineering is a discipline between theory and practice, we try to balance basic research with technology research and application-driven research.

Model-Driven Robot Software Engineering (MORSE)

MORSE is the queen discipline of systems engineering, because constructing, modeling, and programming of robots is hard. Since 2006, the chair is involved in MORSE; first with MDSD for Lego Mindstorms robots in the SuReal project, then for NAO robots in the Qualitune project, then for TurtleBots in the VICCI project, and then for KUKA LBR in the T-RoX project.

Component-Based Software Engineering (CBSE) and Snippet Composition for Models and Programs (Invasive Software Composition)

Software composition integrates the following areas of software engineering: aspect-oriented development, architecture languages, view-based development, and generic programming. The speciality of the Dresden group, Invasive Software Composition (ISC), is a technology for template and snippet composition (fragment composition). Plainly speaking, it is an advanced form of template metaprogramming (TMP), but it can do much more for you. Our group has worked on the following type-safe techniques for snippet composition and for constrution of program and model weavers:
  • With Universal grammar-based ISC for textual languages, you can produce for a given grammar a snippet composition system. With this, you can enhance any language with template programming features like in BETA or C++ and build powerful snippet metaprogramming environments. Applications are [ Safe Template Languages ] and "Component Models for Semantic Web Languages". These works describe a general framework of grammar-universal ISC, i.e., how to take a grammar and generate from it a component model and snippet composition system for its language.
  • Universal metamodel-based ISC for textual and graphical languages is the extended approach working with EMF metamodels [ Extending Grammars and Metamodels for Reuse - the Reuseware approach ] [ JOT Paper on Reuseware ]
  • Orchestration style sheets (OSS) is our newest approach for styling the parallelization and distribution of sequential programs (progressive parallelization). Style sheets are a very general form of rewriting-based aspects, controlled by attribute grammars. [First Paper on OSS]
  • Attribute-driven ISC: With attribute-driven ISC, weavers can be built for Aspect-Orientation Development (AOSD) and Aspect-Oriented Modeling (AOM). Remote Attribute Grammars describe data- and control-flow between remote parts of the syntax tree of the program. The theory was worked out by Dr. Sven Karol in his PhD thesis "Well-Formed and Scalable Invasive Software Composition" [pdf]. The corresponding demonstrator tool is the SkAT composition tool.
  • Reference-attribute grammar driven rewriting ( RACR): if analysis phase of a reference attribute grammar are interchanged with rewriting, a novel method for context-sensitive term rewriting results. The RACR toolset is managed by Christoff Bürger, now in Lund, Sweden.

Agile Business Modeling in Smart Ecosystems (Lean Startup for Software and Innovation Ecosystems)

Context- and Role-Based Modeling (Context-based Views)

During the last years, we have have learned that Model-Driven Software Engineering should be based on languages with contexts and roles (Context- and Role-based Modeling and Metamodeling). Roles capture context-sensitive object behavior in specific contexts. Role systems automatically adapt to context changes. Contexts and roles can be applied to objects, models, and metamodels (for language engineering). This is an exciting new area of MDSD!

Model-Driven Software Engineering (MDSD) in Technical Spaces

MDSD is cool because it shows complex software in simple views (models).

Megamodels and Model-driven software development (MDSD) 

Software Product Lines

Software Product Line Engineering (SPLE) maintains a configuraiton model in the problem space together with a system in the solution space (component space).
  • Feature Modeling
  • Language Families based on Feature Models and Role-based component models. This was the PhD of Christian Wende who modeled language families with feature models.
  • Hyper-feature models. Christoph Seidl developed them in his PhD.
  • Views on Feature Models. Julia Schroeter worked them out for multi-tenant cloud-based software.

Requirements, Testing, and Documentation

  • Ontologies in requirements specification (Katja Siegemund's PhD)
  • OCL and business rules: the chair has an OCL compiler, the Dresden OCL Toolkit
  • Test automation for cyber-physical systems and robots (MATE System, Georg Püschel)
  • Documentation engineering (elucidative development), PhD thesis of Dr. Andreas Bartho
  • Quality-based optimization with Multi-Quality Auto-Tuning (MQuAT) of Dr. Sebastian Götz

Analysis and Transformation Techniques

  • Graph rewriting, in particular Edge Addition Rewrite Systems (EARS) and Exhaustive GRS (XGRS) 
    • Port-Graph Rewriting (Johannes Mey)
  • Reference-attribute grammar driven rewriting (RACR): if analysis phase of a reference attribute grammar are interchanged with rewriting, a novel method for context-sensitive term rewriting results. The RACR toolset is managed by Christoff Bürger, now in Lund, Sweden
    • Bidirectional Edges in Reference-attribute grammars

Development Environments Tool and Generator Technologies

  • Context-based Petri Nets (Carl Mai, Dr Marvin Triebel)
  • Macromodels are sets of models in heterogeneous IDE that are kept consistent and are amenable for round-trip engineering (Christopher Werner)
  • QMARK is a development environment for development of energy-efficient apps (Claas Wilke)
