Sample structure for sharing file information.

# Base file

secure hash of file
file name?  I don't think it should be part of this, as the set of bytes could have any name.
metadata, e.g. code, language

```
{
	'id': 'uuid',
	'hash': 'sha256:xxxx',
	xxxmetadata
}
```

# Links to file from FS

hostname + path
link to base file

How are these versioned?  Are they?

```
{
	'hash': 'sha256:xxx',
	'hostname': 'server.example.com',
	'fqpath': '/some/set/directories/and/filename.ext'
}
```

# Links to file in archive

link to base file
archive hash
name/handle in archive

This is an immutable "fact", treat it differently?

```
{
	'filehash': 'sha256:xxx',
	'archivehash': 'sha256:xxx',
	'archivepath': 'archive/path/to/file.ext'
}
```

# Links to file in torrent

torrent hash
name of file in torrent if multi file torrent

Note: that if the file is in an archive in a torrent, these change be chained.

```
{
	'filehash': 'sha256:xxx',
	'magnet_link': 'magent:xxx',
	'fqpath': 'archive/path/to/file.ext'
}
