	abstract = {Model repositories play a central role in the model driven development of complex software-
		intensive systems by offering means to persist and manipulate models obtained from 
		heterogeneous languages and tools. Complex models can be assembled by interconnecting model 
		fragments by hard links, i.e., regular references, where the target end points to external 
		resources using storage-specific identifiers. This approach, in certain application scenarios, 
		may prove to be a too rigid and error prone way of interlinking models. As a flexible 
		alternative, we propose to combine derived features with advanced incremental model queries as 
		means for soft interlinking of model elements residing in different model resources. These soft 
		links can be calculated on-demand with graceful handling for temporarily unresolved references. 
		In the background, the links are maintained efficiently and flexibly by using incremental model 
		query evaluation. The approach is applicable to modeling environments or even property graphs 
		for representing query results as first-class relations, which also allows the chaining of soft 
		links that is useful for modular applications. The approach is evaluated using the Eclipse 
		Modeling Framework (EMF) and EMF-IncQuery in two complex industrial case studies. The first 
		case study is motivated by a knowledge management project from the financial domain, involving 
		a complex interlinked structure of concept and business process models. The second case study 
		is set in the avionics domain with strict traceability requirements enforced by certification 
		standards (DO-178b). It consists of multiple domain models describing the allocation scenario 
		of software functions to hardware components.},

	abstract = {Model-driven tools frequently rely on advanced technologies to support model queries, view maintenance, design rule validation, model transformations or design space exploration. Some of these features are initiated explicitly by domain engineers (batch execution) while others are executed automatically when certain trigger events are detected (live execution). Unfortunately, their integration into a complex industrial modeling environment is difficult due to hidden interference and unspecified interaction between different features. In this paper, we present a reactive, event-driven model transformation platform over EMF models, which captures tool features as model queries and transformations, and provides a systematic, well-founded integration between a variety of such tool features. Viatra 3 offers a family of internal DSLs (i.e. dedicated libraries) to specify advanced tool features built on top of existing languages like EMF-IncQuery and Xtend. Its main innovation is a source incremental execution scheme built on the reactive programming paradigm ssupported by an event-driven virtual machine.},

	abstract = {Design space exploration (DSE) aims at searching through 
		various models representing different design candidates to 
		support activities like configuration design of critical 
		systems or automated maintenance of IT systems. In model-
		driven engineering, DSE is applied to find instance models 
		that are (i) reachable from an initial model with a sequence 
		of transformation rules and (ii) satisfy a set of structural 
		and numerical constraints. Since exhaustive exploration of 
		the design space is infeasible for large models, the 
		traversal is often guided by hints, derived by system 
		analysis, to prioritize the next states to traverse 
		(selection criteria) and to avoid searching unpromising 
		states (cut-off criteria). In this paper, we define an 
		exploration approach where selection and cut-off criteria are 
		defined using dependency analysis and algebraic abstraction 
		of transformation rules. Additionally, we apply different 
		state encoding techniques to identify recurring states and 
		reduce the number of visited states. Finally, we illustrate 
		our approach on a cloud infrastructure configuration problem 
		and provide detailed evaluation on both synthetic and real 
		applications. This evaluation includes (i) the comparison of 
		several exploration techniques, (ii) performance measurements 
		on multiple state encoding techniques and (iii) comparing two 
		implementation architectures of our design space exploration 
		framework.},
