+# SchemaOrg Verifiable Credentials
+
+This folder contains verifiable credential schemas based on [Schema.org](https://schema.org/) vocabulary, providing standardized representations for various types of digital content and creative works.
+
+## Overview
+
+The SchemaOrg schemas extend the W3C Verifiable Credentials standard with Schema.org vocabulary, enabling rich, semantic representation of digital content while maintaining interoperability with existing Schema.org implementations. These schemas are designed for use in decentralized identity systems and digital content management.

+
+## Implementation Guidelines
+
+### 1. Choose the Right Schema
+- Use the most specific schema for your content type
+- Extend base schemas for custom requirements
+- Consider content relationships and hierarchies
+
+### 2. Provide Required Fields
+- Always include `id` and `schema:name`
+- Use stable, resolvable URIs for identifiers
+- Ensure names are descriptive and meaningful
+
+### 3. Add Rich Metadata
+- Include descriptive information in `schema:description`
+- Add relevant keywords and tags
+- Specify authors, creators, and publishers
+
+### 4. Handle Permissions
+- Use `schema:hasDigitalDocumentPermission` for access control
+- Specify clear permission types and scopes
+- Include audit trails for sensitive content
+
+### 5. Consider Accessibility
+- Add accessibility features and summaries
+- Include alternative formats where possible
+- Specify access modes and requirements
+
+## Contributing
+
+### Adding New Schemas
+1. Create a new folder in `draftSchemas/`
+2. Include `schema.json`, `context.json`, and `README.md`
+3. Follow the existing schema structure and patterns
+4. Update this README with schema documentation
+
+### Schema Requirements
