Part of the Semantic Digest Protocol (SDP)
Last Updated: 2025-07-28
What It Will Do
The Semantic Digest Protocol validator will allow publishers, developers, and AI researchers to:
- ✅ Paste or upload SDT fragments
- ✅ Validate against official SDT schemas by
data-sdt-class - ✅ Check for required provenance fields (if
prov: true) - ✅ Confirm GTP term alignment
- ✅ Preview export format output (TTL, JSON-LD, Markdown)
- ✅ Detect missing or malformed
data-*attributes - ✅ Receive human-readable + machine-readable validation reports
Status: Coming Soon
This tool is under active development.
Expected launch Q3 2025.
If you’re building an SDP-compatible site, or you’d like to test your own fragments against the spec now, feel free to reach out for early access to schema files and test routines.
