Files Metadata about js-ipfs-unixfs-engine

[whyrusleeping]

we encode that information in the unixfs protobuf and store it in the data segment of the merkledag node: https://github.com/ipfs/go-ipfs/blob/master/unixfs/format.go

Where is this metadata schema used throughout the files api routines https://github.com/ipfs/go-ipfs/blob/master/unixfs/format.go#L17?

One more question. When we have a directory, we use the Links file on the MerkleDAG.proto to point to the files and not the data field on the unixFS proto, right?

Another one: Why do symlinks have on their data field the name of the file they are symlinking (just that) and why is that name appended by \u0018\b?

I've found what is the actual problem, although a symlink has data, namely the file name which it is symlinking, it is saying that its filesize is 0, although the alg to calculate the filesize is the sum of block sizes + the length of its own data https://github.com/ipfs/go-ipfs/blob/master/unixfs/format.go#L172-L174 . So, this looks like a bug, or we remove that data from the symlink (which so far, I didn't understand why it is useful), or we make its length right. Thoughts?
