The “Vocal” project (2015–2020) aims at developing the first mechanically verified library of efficient general-purpose data structures and algorithms. It is funded by Agence Nationale de la Recherche under its “appel à projets générique 2015”.

A first release of the library has been published in December 2018. It contains a small number of verified data structures, including resizable vectors, hash tables, priority queues, and Union-Find.

In 2019, progress was made on the definition of Gospel, a standard language for annotating OCaml programs with logical specifications, which could be understood and processed by several verification tools, including Why3 and CFML.
