The Profiles.md documentation was outdated and did not accurately
reflect the significant improvements and new features added in v2, as
well as containing an inaccuracy regarding server-side aggregate
support. This PR updates the document to provide an accurate and
comprehensive profile of current functionality.
## Changes Made
- **Overview**: Updated to highlight v2 improvements and clarified OPC
UA specification version to 1.05.07
- **Server Features**: Added three new Additional Features sections
documenting:
- Alias Names (OPC UA Part 17) with wildcard search
- WoT Connectivity (OPC 10100-1) for IoT asset integration
- Model Change Tracking for address space change notifications
- Added reference to fluent API and dependency injection patterns for
feature configuration
- **Client Enhancements**: Expanded Client Profiles section with new
capabilities:
- Streaming Subscriptions integrated into subscription management
(IAsyncEnumerable-based API)
- Model Change Tracking (address space invalidation)
- File System Operations (System.IO-style async client)
- Alarms and Conditions (full subscription support)
- **Security Profiles**: Significantly expanded security policy
documentation to include v2.0 additions:
- Modern ECC Curves: Curve25519 and Curve448 with AEAD ciphers
- AES-GCM and ChaCha20-Poly1305 variants for traditional ECC curves
- RSA Diffie-Hellman key agreement policies
- Updated platform requirements to reflect modern cipher support needs
- **GDS Expansion**: Added Authorization Service and Key Credential
Service to GDS section for token and credential issuance
- **Restructuring**: Removed "Currently Not Supported (Server)" section
to provide clearer distinction between fully implemented features and
those with limited coverage, and integrated streaming subscriptions as a
subscription management capability rather than a separate profile
- **Documentation**: Added 8 new entries to Related Documentation
linking to comprehensive guides for all v2 features
- **Aggregate Correction**: Corrected the inaccurate claim that
server-side aggregates are not implemented. Server-side aggregates
(Average, Total, Minimum, Maximum, and more) are fully implemented via
streaming fallback and provider push-down. Removed "Aggregates Server
Facet" from the "Currently Not Supported" section.
