What is the relationship between ISCN and IPFS?
The InterPlanetary File System (IPFS) is a decentralized file system protocol for storing and sharing data in a peer-to-peer network. The IPFS hash of the content can serve as the content fingerprint in an ISCN record. IPFS provides a lower-layer protocol foundation.
ISCN registers the important content metadata such as author, publication date, licenses terms, versions, and content fingerprint. It is perfect matched with decentralized file systems like IPFS so that users can search for content indexed by ISCN in a decentralized network more efficiently. ISCN is also a solution to manage versioning and licensing.
The content fingerprint is not necessary an IPFS hash, however, but can be any content address such as an Arweave content ID or even a popular web URL. An ISCN record can even not filling with any content fingerprint but with other metadata only.
