2. tagging scheme

The basic strategy is create a tag library consisting of representative entries for each tag entity. The library (or database) serves as the definitive representation of a COMPOSER/ARTIST. When new files are synchronized to the library, a matching entry is sought within the existing entries. If a match is found the tags of each audio file are updated to match the representation in the database. If a match can’t be found, the entity is added to the database.

An audio file can be characterized by a number of tag fields

2.1. Composer

A COMPOSER composes a piece of music. Classical music generally differs from most genres of popular music in that the performer (ARTIST) is not the same person(s) as the COMPOSER. Example entry:

"Isaac Albéniz": {
    "nationality": "Spanish",
    "period": "Classical/Spanish Folk",
    "full_name": "Isaac Albéniz",
    "abbreviated": "Albéniz",
    "sort": "Albéniz, Isaac",
    "borndied": "1860-1909",
    "permutations": [
        "Albéniz, Isaac",
        "Isaac Albéniz",
        "Albeniz, arr. Christopher Parkening",
        "Albéniz",
        "Albéniz, Isaac (1860-1909)"
    ]
}

2.1.1. Field summary

A few of the notable fields, along with their tag file mappings, are

2.1.1.1. full_name ==> COMPOSER

The name to display

2.1.1.2. nationality ==> COMPOSER_NATIONALITY

Where the composer was born and/or lived during their active years.

2.1.1.3. period ==> COMPOSER_PERIOD

A description of the primary sub-genre associated with the composer.

2.1.1.4. borndied ==> COMPOSER_DATES

The vital dates of the composer’s life.

2.2. Artist

ARTIST performs the music of the audio file and generally presents more of a challenge than does the COMPOSERs.

Often a piece will list multiple performers. For example:
