SVN URLs Migration Report

Executive Summary

This report analyzes 34 legacy SVN repository URLs found across 5 wiki pages that reference viatra.inf.mit.bme.hu/svn. These URLs point to old code repositories that were used before the migration to Git/GitHub and Eclipse infrastructure.

Status: The SVN server is still responding (HTTP 200) but the repositories are outdated. Most code has been migrated to GitHub and Eclipse infrastructure.

Affected Files and URL Count

File SVN URLs Primary Content
A-Benchmark-Evaluation-of-Metrics-for-Graph-Query-Performance-Prediction.md 13 Train Benchmark code and models
Benchmarking-query-technologies-in-EMF-based-model-validation-scenarios.md 9 Train Benchmark validation scenarios
Model-driven-framework-for-Design-Space-Exploration.md 4 DSE framework code
Incremental-Pattern-Matching-for-the-Efficient-Computation-of-Transitive-Closure.md 4 Pattern matching and ITC algorithms
VIATRA2-GRaTS-Stochastic-Graph-Transformation-System.md 4 Stochastic simulation code

Total: 34 SVN URLs across 5 files

URL Categories by Repository

1. IncQuery Repository (23 references)

Path pattern: https://viatra.inf.mit.bme.hu/svn/incquery/trunk/

Most references point to Train Benchmark implementations:

  • /examples/code/trainBenchmark/ - Various benchmark implementations
  • /examples/models/trainBenchmark/ - Instance models
  • /runtime/ - ITC implementation

Current Location:

2. Stochastic Simulation (3 references)

Path pattern: https://viatra.inf.mit.bme.hu/svn/stochsim/trunk/

Stochastic graph transformation tools and plugins.

Current Location:

3. Transformations Repository (3 references)

Path pattern: https://viatra.inf.mit.bme.hu/svn/transformations/collab/trunk/

Collaborative transformation examples and stochastic GT.

Current Location: Likely integrated into main VIATRA repository

4. DSE Repository (1 reference)

Path pattern: https://viatra.inf.mit.bme.hu/svn/dse/trunk/

Design Space Exploration framework.

Current Location: Part of VIATRA DSE module

5. Experimental Repository (3 references)

Path pattern: https://viatra.inf.mit.bme.hu/svn/experimental/trunk/

DSE extensions and experimental features.

Current Location: Unclear - likely deprecated or merged

6. Core Repository (1 reference)

Path pattern: https://viatra.inf.mit.bme.hu/svn/core/branches/

Current Location: Integrated into VIATRA framework

Migration Status

✅ Successfully Migrated

⚠️ Archived/Historical

❓ Unclear Status

  • Experimental extensions
  • Some transformation examples
  • Specific benchmark configurations

Recommendations

Immediate Actions

  1. Do NOT remove SVN URLs yet - They serve as historical documentation
  2. Add migration notes - Include notes about where code has moved
  3. Verify Train Benchmark - Most affected pages relate to this benchmark

Future Actions

  1. Contact maintainers - Verify correct migration paths for unclear repositories
  2. Update with GitHub links - Add parallel GitHub/Eclipse links where available
  3. Archive notice - Add notices that SVN links are historical references

Sample Migration Note

For affected pages, consider adding a note like:

> **Note:** The SVN repositories referenced below are historical. Current development has moved to:
> - VIATRA Framework: https://eclipse.org/viatra
> - Train Benchmark: https://github.com/FTSRG/trainbenchmark
> - Examples: https://github.com/viatra/
