We don't have to use TAR.

  "fileCatalog": {
     "a/fileA.txt": "cwjisj449...",

        "ref": "dijoi3j....",
        "mode": ["executable", ....],

flat structure:

{
   "fileCatalog": {
     "a.txt": "ddhash...", // file
     "b.txt/": "dddsa...", // directory
   }
}

Default is a hash.

If we need additional attributes, like 'executable', 'mime-type'?, then we use an object instead of string. For example:

{
   "fileCatalog": {
     "a.txt": "ddhash...", // file
     "b.txt/": {
        "ref": "dddsa...", 
        "attributes": ["executable", "read-only"],
     }
   }
}

Extension for the format:

Data inside the object:

{
   "fileCatalog": {
     "a.txt": "ddhash...", // file
     "b.txt/": {
        "data": {
           "a": { "data": "...base64......." }
        },
        "attributes": ["executable", "read-only"],
     }
   }
}

Full path

{
   "fileCatalog": {
     "a.txt": "ddhash...", // file
     "c/d/r/b.txt/": {
        "data": {
           "a": { "data": "...base64......." }
        },
        "attributes": ["executable", "read-only"],
     }
   }
}

Different hash formats:

{
   "defaultHashFormat": "cdt0",
   "fileCatalog": {
     "a.txt": "sha256:ddhash...", // file
     "c/d/r/b.txt/": {
        "data": {
           "a": { "data": "...base64......." }
        },
        "attributes": ["executable", "read-only"],
     }
   }
}
