Research Areas

My main research areas are the following. Since software engineering is a discipline between theory and practice, we try to balance basic research with technology research and application-driven research.

Component-Based Software Engineering (CBSE) and Invasive Software Composition

Software composition integrates the following areas of software engineering: aspect-oriented development, architecture languages, view-based development, and generic programming. 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).
  • 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

Model-Driven Software Engineering and Role-Based Modeling

Megamodels and Model-driven software development (MDSD) in Technical Spaces

  • Model synchronization and round-trip engineering This technology keeps a set of models and codes consistent, so that they are called a megamodel.
  • Role-based Modeling and Metamodeling: Roles capture context-sensitive object behavior and can be applied to objects, models, and metamodels (for language engineering). Role systems automatically adapt to context changes.
  • Ontology-Driven Software Development (ODSD): ODSD couples ontologies to software models, to be able to use advanced reasoning technologies in requirements engineering or design. Dr. Katja Siegemund has worked on the employment of ontologies in requirements specification [pdf].
  • Course Model-Driven Software Development in Technical Spaces (MOST) summarizing the most modern literature in the research area. It discusses macromodels, megamodels, technical spaces and other ways to develop REAL software.

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
  • Hyper-feature models

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.

Requirements and Testing

  • Ontologies in requirements specification
  • OCL and business rules: the chair has an OCL compiler, the Dresden OCL Toolkit
  • Test automation for cyber-physical systems
  • Documentation engineering (elucidative development)

Smart Ecosystems (Software and Innovation Ecosystems)

Tool and Generator Technologies

  • Graph rewriting, in particular Edge Addition Rewrite Systems (EARS) and Exhaustive GRS (XGRS) 
  • Port-Graph Rewriting
  • Context-senstitive term rewriting based on reference attribute grammars (RACR)
  • Context-based Petri Nets
