What EXIF Standard (Metadata) requires
Compliance with the Exchangeable image file format standard is rigorously enforced to ensure data integrity and interoperability for all digital still-camera image assets. This validation mandates strict adherence to the CIPA DC-008-2023 specification, requiring a valid Exif Version 3.0 signature for all processed files. The underlying file structure must conform to the TIFF/EP image data format described in ISO 12234-2:2001, with the TIFF header offset not exceeding a maximum of 8 bytes. Consistent byte order, whether little or big endian, must be maintained throughout the file structure to prevent data corruption. The node enforces the complete Section 4 image data structure, which includes the mandatory presence of a GPS Info IFD as specified in section 4.3 and an Interoperability IFD index to align with standards like the ISO/IEC 23000-3:2007 photo player application format. All textual metadata must use UTF-8 character encoding. Furthermore, critical photographic parameters are required, making the FNumber (aperture), ExposureTime, and PhotographicSensitivity (ISO) tags mandatory for validation. To mitigate security risks, any execution of proprietary MakerNote code is explicitly disallowed. The total metadata payload is constrained to a maximum size of 65536 bytes, with its storage and handling governed by principles analogous to those in NIST SP 800-111 for safeguarding sensitive information. This comprehensive approach ensures that image metadata is not only structurally sound per RFC 3950 but also complete, secure, and universally interpretable.
