In 2003, Resonant (Centre for Musical Heritage) developed Muziekbank Vlaanderen, a database for musical heritage in Flanders and Brussels. It holds descriptions of archives and collections from composers and music organizations in private and public holding institutions.
The Fédération Wallonie-Bruxelles presents a list (PDF) made by Marie Cornaz with documents and collections from the 17th century onwards in different holding institutions.

Italy
The Directorate-General of Archives of the Italian Ministry of Cultural Assets and Activity has sustained since 2009 a multi-level project aiming to give access to descriptions and digital versions of music documents. It provides scholars and musicians with a database including descriptions from Archivi di Stato, Soprintendenze archivistiche, public and private institutions and foundations.
In accordance with AMA's focus, the portal features a basic set of records according to ISAD and EAD standards: owning institution ; fund/s (or collection/s) ; creator/s (or collector/s)
If more detailed inventories are available, links are provided. A number of them still exist, but on different and often obsolete media that have to be updated and eventually transferred. Luckily, future developments aim to also include ISAD level 3 and 4 implementation.
