Service-Oriented Design Methodology + Tests (SODM+T)

This is the source code for the programs used to develop SODM+T, an extended version of the SODM model-driven methodology for service-oriented systems.

Unless otherwise specified, the code is under the Eclipse Public License 2.0 with secondary GPLv3 license and is copyright (C) 2008-2022 Antonio García Domínguez.

For additional information beyond this document, check the project website.

Installation

To use the SODM+T toolset, first download and run the Eclipse Installer.

Switch to Advanced Mode, and pick "Eclipse Modeling Tools" in its 2021-12 version (2022-03 is known not to work at the moment). Click on "Next".

In the "Projects" page:

  1. Click on the "+" button.
  2. Select the "Github Projects" option within "Catalog".
  3. Paste the URL of this link into the "Resource URIs" field.
  4. Click on OK.
  5. Tick the "SODM+T Models GIT" option.
  6. Click on "Next".

In the "Variables" page, you can simply click on "Next".

In the "Confirmation" page, you can also click directly on "Finish".

In the "Progress" page, trust the software sources, and click on "Finish" when done.

After some time, the new installation will start on its own: Eclipse will clone this repository and import a collection of sample models: after some time, you will be able to click on "Finish" and start using SODM+T.

Basic usage

For a full discussion, please check the PhD thesis and viva slides (both mostly in English) from the University of Cádiz's institutional repository.

Please start by opening the ws.profile/model.profile.di and wsdl.profile/model.profile.di files, to set up the WS and WSDL Papyrus profiles before opening any other models.

After this, you can study the remaining projects:

  • es.uca.b2mml.perftest has an example set of performance models, created for the SchedulerImplService in the example-isa95 project.
  • examples.adhoc.v2 has an example service process diagram that you can use to test out the algorithm with the lightweight UML-inspired notation, by right-clicking on the background of the diagram and using one of the "Wizards - Infer..." options ("Infer performance annotations" is the EOL-based graph-based incremental time limit inference algorithm and the throughput inference algorithm, "Infer time limits (old algorithm)" is the EOL-based exhaustive time limit inference algorithm, and "Infer time limits (GLPK)" uses the glpsol solver by generating constraints in an exhaustive manner as well).
  • examples.marte has an UML activity diagram which can also be used to play with the SODM+T algorithm. To represent the time limits, it uses the MARTE GQAM profile as implemented by Papyrus. In this case, you will have to right-click on the top-level activity in the diagram and select the relevant option in "Wizards". Only the incremental graph algorithm is available for MARTE.
  • examples.weaving.modisco contains a set of Java models extracted from the example-orders program with MoDisco, and a weaving model that relates the Java models to the performance requirements. You can generate ContiPerf performance tests from it by switching to the "Java" perspective, right-clicking on the ws-impl.modisco_perfreq file, and selecting "SODM+T for MoDisco - Generate Performance Tests". You can also see how they related to each other by opening the .modelink file in its weaving subfolder, using Epsilon ModeLink.
  • examples.weaving.wsdl contains a similar set of models, but rather than Java the models relate to a message catalog extracted from a WSDL file by ServiceAnalyzer, and a corresponding orders.wsdl_perfreq weaving model (with its own .modelink file for 3-way browsing).
  • keraben.processes contains a mix of models extracted from the example-isa95 project, together with their weaving models.
  • keraben.usecases contains the SODM Use Case and Extended Use Case diagrams for the above case study, which were created as part of the case study for the PhD.

Update site

This project also has a standard update site here, in case you would like to use your existing Eclipse installation:

https://agarciadom.github.io/sodmt/updates/1.0.3/

Please note that this is not a browsable link: you will need to use it from the Eclipse "Help - Install New Software..." menu.
