MLT-Telos: Implementation and Examples

This directory contains the up-to-date implementation and examples for MLT-Telos, the implementation of MLT* on top of O-Telos in ConceptBase. The source code for MLT-Telos and the examples are a supplement to the paper

Manfred A. Jeusfeld, João Paulo A. Almeida, Victorio A. Carvalho, Claudenir M. Fonseca, Bernd Neumayr:
Deductive reconstruction of MLT* for multi-level modeling.
Original paper appeared in ACM/IEEE 23rd International Conference on Model Driven Engineering Languages and Systems (MODELS '20 Companion), 
Workshop MULTI 2020, Virtual Event, Canada, DOI 10.1145/3417990.3421410.

Changelog

The source models (*.sml, *.sml.txt,*.cbs) in this directory (incl. subdirectories) and their derivates (*.gel,*.png) are provided under a CC BY-SA 4.0 license: Attribution-ShareAlike 4.0 International. You need ConceptBase 8.1 released July 2020 or later to test the implementation. Download it from http://conceptbase.cc.

The sources of MLT-Telos can be found in the SOURCES directory. The sources can be loaded into a ConceptBase server to configure it for MLT-Telos. Self-contained graph files with examples of MLT-Telos can be found in the GELs directory. The directory also contains the MLT-Telos source code for the examples (see als the paper above). They are really short. The GEL files are self-contained, i.e. they contain all necessary definitions like the deductive rules and constraints specifying MLT-Telos.

Examples from the MULTI 2020 paper

In the following, we list the example graph files that are used in out paper as figures. The links behind the images point to the graph files, which can directly start the ConceptBase graph editor, if you have installed and configured it appropriately, see http://conceptbase.sourceforge.net/CB-Download.html and http://conceptbase.sourceforge.net/CB-Mime.html.
