ETAPS is an umbrella venue for several established conferences and workshops. This year we have three contributions to ETAPS:
= Our paper Intermodeling, queries, and Kleisli categories will be presented at FASE'12
= Yingfei and Zinovy were in the PC of the BX'12 Workshop, which is striving to be a visible point on the map. The next edition, BX'13, is already accepted to be affiliated with ETAPS'13. The program of BX'12 is here

We have released ECC fixer 0.1. This is a preliminary release mainly served as supplementary material for paper Generating Range Fixes for Software Configuration.

Based on our survey, solving configuration errors and activating inactive features are two main challenges faced by today's configurator users. This paper proposes a new concept, range fixes, to assist users dealing with the two challenges. A technical report version of the paper can be found here.

This tutorial (attached) introduces domain concept modeling using Clafer. The tutorial explains concept modeling using well-known document and slide structuring metaphors, easy to understand examples, and then it introduces Clafer a bit more precisely. The tutorial also contains an exercise: modeling of the concept Book and a reference solution. We recommend working with the tutorial in the following way:

We have been working very intensively on Clafer in the last couple of months.
The Clafer translator got updated to version 0.1, which brought a few extensions to the language and changes to syntax. If you play with the online translator, you will notice that the translator can output models in several new formats:

• XML format with intermediate representation (IR) of the model. IR allows to combine the Clafer translator with other tools that further process Clafer models.

This paper summarizes our findings in our online survey about configuration challenges.

We have conducted an online survey about what challenges are faced by the users of modern configuration tools. The result was published here as a technical report.

The website got updated with two online tools. You can try them without having to download and compile source code. CDL to Clafer translator takes an eCos' variability model specified in the CDL language and outputs corresponding Clafer model. We believe the Clafer model is easier to read and comprehend. It is also analyzable by SAT/SMT solvers.
