Hi everyone,
I'd like to share an open-source extension framework we've developed for AtoM 2.8 - 2.10 that may be useful to the community.

Demo/developemnt site: https://psis.theahg.co.za/index.php/

What is it?
The AtoM AHG Framework adds Laravel Query Builder integration while maintaining full Symfony compatibility. It provides a modular plugin ecosystem specifically designed for GLAM institutions (Galleries, Libraries, Archives, Museumsand Digital Asset Management).

Key Features: 

🏛️ Multi-Sector Support

 - Sector-specific templates and controlled vocabularies
- Switch between display modes per sector

🔒 Security & Compliance 
 - 5-level security classification (Public → Top Secret)
 - Privacy compliance for 6 jurisdictions (POPIA, GDPR, PIPEDA, CCPA, NDPA, Kenya DPA)
 - Heritage asset accounting (GRAP 103, FRS 102, IPSAS 45, and 7 more standards)
 - Comprehensive audit trails

🎬 Enhanced Media 
 - 3D model viewer (GLB/GLTF) with AR support
 - Audio player with waveform visualization and snippet creation  

 - Speech-to-text transcription (Whisper, 90+ languages)
 - IIIF integration with OpenSeadragon and Mirador
 - Automatic metadata extraction (EXIF, IPTC, XMP)
 - TIFF to PDF/A merge tool 

🔬 Research & Access 

 - Researcher registration and approval workflows 

 - Reading room booking system 

 - Access request management  

 - Embargo system with propagation to children 

🛠️ Utilities

 - Barcode generation and scanning 

 - Data migration tool (import from Vernon CMS, ArchivesSpace, PastPerfect, DB/TextWorks)
