This TTL Validator tool allows you to validate Turtle RDF syntax either by pasting TTL code directly or uploading a .ttl file. The tool performs comprehensive syntax checking including proper @prefix declarations, valid IRIs, correct literal formatting, proper use of semicolons and commas, and valid blank node syntax. It provides detailed error messages with line numbers, syntax highlighting, and a visual representation of the parsed structure. The validator supports all TTL features including collections, nested blank nodes, and SPARQL-style prefixes.

Frequently Asked Questions

Find Quick Answers

What is TTL (Turtle) format?
TTL (Turtle) is a syntax for expressing RDF (Resource Description Framework) data in a compact, human-readable text format. It's commonly used in semantic web applications and linked data projects.
What types of errors does this validator detect?
The validator detects syntax errors like missing prefixes, invalid IRIs, malformed literals, incorrect punctuation, unbalanced brackets, and structural issues with blank nodes and collections.
Can I validate large TTL files?
Yes, the tool can handle files up to 10MB. For optimal performance with very large files, consider splitting them into smaller chunks.
Does this tool store my TTL data?
No, all validation happens client-side in your browser. Your TTL data is never sent to any server or stored anywhere.
What validation options are available?
You can choose between standard validation (checks basic syntax) and strict mode (additional checks for best practices and common pitfalls).
