The ESCB  TF on the shared SDMX Tools has published the VTL Engine and Editor prototype as an Open Source Software in Github, under a EUPL license. This is a tool that can be used to develop, validate and execute VTL rules and it is developed as a Java library (that contains 100% of the VTL engine and can be used by itself) wrapped by an R package (that contains the graphical editor, the VTL Studio, and a set of R commands to interact with the engine).

The Github repository is located at: https://github.com/vpinna80/VTL

Binary versions of the tool, ready to be installed in R, will be located at: https://github.com/vpinna80/VTL/releases/

It is expected that the package will be available directly from CRAN, the official R repository soon.

Mr. Attilio Mattiocco, (IT Architect at Banca d’Italia and the Chair of the TF of Shared Tools) can be contacted for questions and feedback on the tool:  attilio.mattiocco@bancaditalia.it
