What is the UnExoticA Tune Information List (UTIL)?

The UnExoticA Tune Information List (UTIL) contains useful facts and enlightening trivia about all the music files in ExoticA's UnExoticA Amiga music collection.

The UTIL is obviously inspired by the HVSC STIL and is structured very similarly to it, but since HVSC .sid files have a file header containing the facts and most Amiga music formats don't, this is where the structure has to be different.

The UTIL contains an MD5 checksum of every file in UnExoticA and is the whole database is sorted by the MD5.

What is the format of UTIL?

To better present the information contained in UTIL and to make it easier for programs and scripts to process and maintain the list of entries in it, UTIL has a strict format that is outlined below.

As you can see, UTIL is a so-called flat text-file, which is readable by humans. But it is formatted in a way that machines (programs) can parse it, too.

In summary, UTIL is more or less like a flat database.


Conventions used in the format description of UTIL

The current standard header for each UTIL entry consists of the following fields: -

    MD5: 
  XPATH: 
 XTITLE: 
  XCOMP: 
  XYEAR: 
XFORMAT: 
   XRIP: 

It then proceeds to follow the original HVSC UTIL block layout.


Description of the UTIL block

In general, UTIL entries are built up of one or more "blocks", depending on how many subtunes a given music file has and how many of those have information attached to them.

The general format of a UTIL block is:

   NAME: Name field
 AUTHOR: Author field
  TITLE: Title field [from Album]
 ARTIST: Artist field
COMMENT: Comment field.

Or for tunes that contain multiple covers:

    MD5: 
COMMENT: *Optional* tune-global comment goes here.
  XPATH: 
 XTITLE: 
  XCOMP: 
  XYEAR: 
XFORMAT: 
   XRIP: 
   NAME: Name field
 AUTHOR: Author field
  TITLE: Title field [from Album] (TIMESTAMP)
 ARTIST: Artist field
COMMENT: Comment field.
  TITLE: Title field [from Album] (TIMESTAMP)
 ARTIST: Artist field
COMMENT: Comment field.
.
.
.

There can be as many covers listed within a UTIL block for tunes that cover more than one piece of music as needed - there is no maximum limit.

Please, see the UTIL field descriptions below for details about the individual fields found in a UTIL block.

All of the fields in the UTIL block are optional, but at least one field must be present. Eg. if only a comment is provided for a tune that has no subtunes, the following entry is perfectly fine:

    MD5: 00000000000000000000000000000000
COMMENT: This should be some relevant comment here.

However, if more than one field is present, they must be in the order as outlined above (NAME first, then AUTHOR, TITLE, ARTIST, and COMMENT).

Description of the complete UTIL entries

Each UTIL entry comprises of one or more UTIL blocks:

FOR MUSIC FILES CONTAINING ONLY A SINGLE TUNE
    MD5: 00000000000000000000000000000000
{UTIL block}
FOR MUSIC FILES CONTAINING MORE THAN ONE TUNE
    MD5: 00000000000000000000000000000000
COMMENT: *Optional* file-global comment goes here.
(#1)
{UTIL block}
(#2)
{UTIL block}
(#3)
{UTIL block}
.
.
.
etc.

Of course, UTIL entries need to be provided only for those tunes that need it, so the following is perfectly fine, too:

    MD5: 00000000000000000000000000000000
COMMENT: *Optional* file-global comment goes here.
(#8)
{UTIL block}
(#11)
{UTIL block}

However, the UTIL blocks for the subtunes must be sorted by ascending order of the tune numbers of the subtunes.
