Photo Metadata Editor

Purpose & User Intent: The Photo Metadata Editor targets photographers, archivists, stock libraries, and digital asset teams needing accurate, consistent metadata for image assets. It solves fragmented EXIF, IPTC, and XMP data by offering a centralized, non-destructive workflow to view and modify fields such as Title, Description, Creator, Keywords, Copyright, GPS, CreationDate, and License. Use cases include catalog ingestion, rights management, and batch tagging.
Core Logic & Features: The tool parses embedded metadata from input images, validates formats, and presents editable fields in grouped panels. Required features: import images; support EXIF/IPTC/XMP; non-destructive preview; batch edits; re-embed or export sidecar files. Optional features: metadata templates, duplicate detection, and API-ready export. Edits maintain data integrity and produce explicit change history.
Inputs & Outputs: Inputs include image files such as JPEG, TIFF and common RAW derivatives and export options. Outputs are updated images with embedded metadata or metadata files such as XMP or CSV/JSON. Validation covers date formats, keyword length, GPS ranges, and field-specific constraints. The tool preserves original binary data and offers an edit log for auditing.
Algorithms & Calculations: Reads metadata sections, normalizes values such as dates and keywords, applies templates when configured, and checks required fields. It resolves conflicts, ensures compatibility with EXIF/IPTC/XMP schemas, and outputs metadata ready for re-embedding or sidecar export.
Error & Edge Cases: Handles missing metadata gracefully, flags invalid dates or GPS data, reports unsupported schemas, and returns actionable error codes for export failures or write permissions.
Industry/Region & Localization: Follows standard metadata schemas EXIF 2.31, IPTC IIM, XMP. Date formats use ISO 8601; language tags support basic localization. Rights-related fields may require jurisdiction-specific notes.
Assumptions & Exclusions: Assumes input files are readable and metadata blocks accessible. Excludes editing non-metadata bits of files, marketing language, and UI-specific guidance.
