+| Attribute  | Type | Description  | Examples  |
+|---|---|---|---|
+| `code.column` | int | The column number in `code.filepath` best representing the operation. It SHOULD point within the code unit named in `code.function`. | `16` |
+| `code.filepath` | string | The source code file name that identifies the code unit as uniquely as possible (preferably an absolute file path). | `/usr/local/MyApplication/content_root/app/index.php` |
+| `code.function` | string | The method or function name, or equivalent (usually rightmost part of the code unit's name). | `serveRequest` |
+| `code.lineno` | int | The line number in `code.filepath` best representing the operation. It SHOULD point within the code unit named in `code.function`. | `42` |
+| `code.namespace` | string | The "namespace" within which `code.function` is defined. Usually the qualified class or module name, such that `code.namespace` + some separator + `code.function` form a unique identifier for the code unit. | `com.example.MyHttpService` |
