Specification: unixfs-v2

Status: Prescriptive - Draft

The following schema is used to represent files and directories in pure IPLD Data Model. It differ substantially from UnixFSv1 which is built exclusively on dag-pb and is currently integrated into IPFS.

This schema makes use of two existing data structures, HAMT and FBL.

type Symlink struct {
	target String
}

type DirEnt struct {
	attribs optional Attribs
	content AnyFile
}

type AnyFile union {
	| "f" FBL
	| "d" &HAMT
	| "l" Symlink
} representation keyed

type Attribs struct {
	# we'll discuss this in the next section;
	# for now, it's enough to reserve the position where it's used.
}
