Library Metadata & Ratings

Phase: P1-S9

Phlix implements a comprehensive rating and metadata system that supports numerical ratings, smart collection rules, fuzzy title matching, and multi-language metadata fallback.

Numerical Ratings

Rating Scale

Ratings use a 0-10 scale internally, displayed in the UI as stars or numeric values depending on context.

Internal Value	Star Display	Numeric Display
0	No stars	0.0
1-2	★☆☆☆☆	1-2
3-4	★★☆☆☆	3-4
5-6	★★★☆☆	5-6
7-8	★★★★☆	7-8
9-10	★★★★★	9-10

Rating Storage

Ratings are stored in the media_items table:

• rating — Community rating (float 0.0-10.0)
• user_rating — Per-user personal rating (int 1-10, nullable)

Sorting & Filtering

Sort by Rating

GET /api/v1/media?sort=rating&order=desc&limit=50
GET /api/v1/media?sort=rating&order=asc&limit=50

Parameters:

• sort=rating — Sort by community rating
• order=asc|desc — Sort direction (default: desc)

Filter by Minimum Rating

GET /api/v1/media?min_rating=7.5

This returns only items with a community rating >= 7.5.

Smart Collection Rules

Smart collections use flexible rule-based filtering:

Rule Types

Rule	Field	Example
Genre	genres[]	genres[]=Action&genres[]=Sci-Fi
Decade	yearFrom, yearTo	yearFrom=1980&yearTo=1989
Rating Threshold	min_rating	min_rating=8.0
Year Range	yearFrom, yearTo	yearFrom=2010

Example: High-Rated 80s Action Movies

GET /api/v1/media?genres[]=Action&genres[]=Sci-Fi&yearFrom=1980&yearTo=1989&min_rating=7.0

Rule Combination

Rules are combined with AND logic. Use multiple genre filters for OR behavior within genres.

Fuzzy Title Matching

Phlix uses Levenshtein distance for fuzzy title matching to handle typos and variations:

How It Works

1. Query text is normalized (lowercase, punctuation removed)
2. Levenshtein distance computed against all titles in library
3. Items with distance <= 3 (or 20% of title length, whichever is smaller) are included
4. Results sorted by relevance (smallest distance first)

Example Matches

Query	Title	Distance	Match
taron	"Tarzan"	2	✅
batmann	"Batman"	2	✅
x-men 92	"X-Men '92"	3	✅
star trek ds9	"Star Trek: Deep Space Nine"	5	❌

API Usage

GET /api/v1/media?search=tarzan&fuzzy=true

Multi-Language Metadata Fallback

Phlix supports a fallback chain for metadata in multiple languages:

Fallback Priority

1. Primary Language — User's preferred language (from profile settings)
2. Secondary Language — Backup language (configurable)
3. English — Always available as final fallback
4. Original Title — If no translation exists

Configuration

{
  "metadata": {
    "primaryLanguage": "en",
    "fallbackLanguages": ["es", "fr", "de"],
    "useOriginalTitle": true
  }
}

Fallback Behavior

Primary	Secondary	Tertiary	Available
English	Spanish	French	English
Spanish	English	French	Spanish
German	English	French	English
Japanese	English	French	Original (Japanese)
