| 27 | * Defines the contract for reading and exposing normalized metadata from a |
| 28 | * Composer `composer.json` file. |
| 29 | * |
| 30 | * This interface provides convenient accessors for commonly used package |
| 31 | * metadata, including identification, descriptive attributes, licensing, |
| 32 | * authorship, support channels, funding declarations, autoload mappings, |
| 33 | * configuration entries, scripts, and additional package-specific sections. |
| 34 | * |
| 35 | * Implementations of this interface MUST read data from a Composer-compatible |
| 36 | * source and SHALL expose that data through stable, predictable, typed accessors. |
| 37 | * When a given field is optional in Composer metadata and not declared by the |
| 38 | * package, implementations SHOULD return an appropriate empty value, nullable |
| 39 | * value, or default representation as described by each method contract. |
| 40 | * |
| 41 | * Returned values SHOULD preserve the semantic meaning of the underlying |
| 42 | * `composer.json` document. Implementations MAY normalize values for |
| 43 | * interoperability and developer convenience, provided that such normalization |
| 44 | * does not materially alter the intended meaning of the original metadata. |
| 45 | * |
| 46 | * The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", |
| 47 | * "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this |
| 48 | * interface are to be interpreted as described in RFC 2119. |
