+The foundation uses a knowledge graph to manage its collections. This graph is a lasagne with 3 "layers", plus one :
 
   - The central and most important layer is the **content description** of the batches of documents held by the foundation. This part is maintained by _archivists_, and is modeled in [RiC-O](https://www.ica.org/resource/records-in-contexts-conceptual-model/)
-  - The “lower” layer (conceptually speaking) is the **physical description** of the documents, including **digital media**. This part is maintained by _curator-restorers_. It is also based on RiC-O (these are Instantiations), but extended with specific metadata for media description coming notably from [ebucore](https://tech-metadata.ebu-it-tools.ch/ontologies/ebucore/index.html) and [premis](https://www.loc.gov/standards/premis/).
