-- **`org.cnai.model.filepath`**: Specifies the file path of the layer (string).
+- **`org.cncf.model.filepath`**: Specifies the file path of the layer (string).
 
-- **`org.cnai.model.file.metadata+json`**: Specifies the metadata of the file (string), value is the JSON string of [File Metadata Annotation Value](#File-Metadata-Annotation-Value).
+- **`org.cncf.model.file.metadata+json`**: Specifies the metadata of the file (string), value is the JSON string of [File Metadata Annotation Value](#File-Metadata-Annotation-Value).
 
-- **`org.cnai.model.file.mediatype.untested`**: Indicates whether the media type classification of files in the layer is untested (string). Valid values are `"true"` or `"false"`. When set to `"true"`, it signals that the model packager has not verified the media type classification and the type is inferred or assumed based on some heuristics.
