GitHub for Semantic Models
Collaborate on semantic web patterns, share ontologies, and build the next generation of linked data applications.
Why Semantic Models Matter
Universal Data Language
Create semantic models that work across systems, languages, and organizations. Define once, use everywhere.
Collaborative Modeling
Work together on ontologies and vocabularies. Fork, merge, and version your semantic models just like code.
Discover & Reuse
Find existing patterns and models. Why reinvent the wheel when you can build on proven foundations?
How Pletka Works
Create or Import
Start from scratch or import existing RDF schemas, OWL ontologies, or SKOS vocabularies.
Collaborate
Invite team members, review changes, and iterate on your models with full version control.
Publish & Share
Make your models discoverable. Generate documentation, APIs, and export to standard formats.
Integrate
Use our APIs to integrate semantic models directly into your applications and workflows.
