Support RDF Import and Provide JSON Schema Import Example

[ayudhien]

First of all, thank you for the amazing work on Living Textbook! I really appreciate the flexibility to export data in multiple formats such as Concept/Instance, Learning Path, RDF (JSON-LD), Simple Linked Nodes, and Relations.

Currently, the app allows importing data only as JSON. I’d like to suggest two improvements:

1. Support RDF Import

• Since RDF export is already available (e.g., JSON-LD), it would be very useful to also allow RDF import.
• This would make it easier to round-trip data between Living Textbook and other RDF-based tools.
• Suggested formats for import:
  • JSON-LD (matching the export format)
  • Optionally, Turtle (.ttl) or RDF/XML

2. Provide JSON Schema or Example for Import

• It would be helpful to include either:
  • A formal JSON Schema definition for the accepted JSON import format, or
  • A complete example file showing the required structure and fields.
• This will make it easier for users to prepare valid import files or convert external data.

Potential Benefits

• Simplifies integration with semantic web and knowledge graph tools.
• Encourages contributions and broader use of Living Textbook in linked data workflows.

Would you consider adding RDF import support and sharing the JSON schema or an example in the documentation?
Thank you!
