+- **Store/State** goes in `whyis_vue/store/`
+- **Tests** mirror the source structure in `tests/`
+
+### Testing Requirements
+
+- All migrated code must have comprehensive unit tests
+- Tests should cover:
+ - Happy path scenarios
+ - Error cases
+ - Edge cases
+ - Integration with other components
+
+### API Compatibility
+
+- Maintain backward compatibility where possible
+- Use similar prop names and events as Angular directives
+- Document any breaking changes
+
+## Test Coverage
+
+- **Total Test Suites**: 39
+- **Total Tests**: 585
+- **All Passing**: Yes ✓

+
+## Build Configuration
+
+### Babel Setup
+
+- Using Babel 7 with bridge for Vue component testing
+- Configuration in `babel.config.cjs` and `.babelrc`
+- Successfully compiling Vue single-file components in tests
+
+### Dependencies
+
+Key development dependencies added/configured:
+- `babel-core@^7.0.0-bridge.0` - Babel 7 bridge for vue-jest
+- `@babel/core@^7.28.4` - Babel 7 core
+- `@babel/preset-env@^7.28.3` - Babel preset
+- `vue-jest@^3.0.7` - Vue component testing
+
+## Usage Examples
+
+### Using URL Utilities
+
+```javascript
+import { getParameterByName, decodeDataURI } from '@/utilities/url-utils';
+
+// Get query parameter
+const query = getParameterByName('q'); // from ?q=search
+
+// Decode data URI
+const result = decodeDataURI('data:text/plain;base64,SGVsbG8=');
+console.log(result.value); // 'Hello'
+```
+
+### Using Label Fetcher
+
+```javascript
+import { getLabel, getLabelSync } from '@/utilities/label-fetcher';
+
+// Async label fetch
+const label = await getLabel('http://example.org/resource/123');
+
+// Sync from cache
+const cachedLabel = getLabelSync('http://example.org/resource/123');
+```
+
+### Using Format Utilities
+
+```javascript
+import { getFormatFromFilename, isFormatSupported } from '@/utilities/formats';
+
+// Get format from filename
+const format = getFormatFromFilename('data.ttl');
+console.log(format.mimetype); // 'text/turtle'
+
+// Check if format is supported
+if (isFormatSupported('rdf')) {
+ // Handle RDF file
+}
+```
+
+### Using Vue Components
+
+```vue
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+```
+
+## Template Migrations
+
+### Completed Vue-based Templates (base_vue.html)
+
+1. **edit_instance_view_vue.html** - Edit instance form using Vue
+ - Uses `edit-instance-form.vue` component
+ - Bootstrap 5 styling
+ - Replaces Angular-based `edit_instance_view.html`
+
+2. **new_instance_view_vue.html** - New instance creation form using Vue
+ - Uses `new-instance-form.vue` component
+ - Bootstrap 5 styling
+ - Replaces Angular-based `new_instance_view.html`
+
+3. **explore_vue.html** - Knowledge graph exploration using Vue
+ - Uses `knowledge-explorer.vue` component
+ - Full-screen layout for graph visualization
+ - Replaces Angular-based `explore.html`
+
+4. **concept_view_vue.html** - Concept/class view using Vue
+ - Uses `nanopubs.vue` for commentary
+ - Bootstrap 5 card-based layout
+ - Replaces Angular-based `concept_view.html`
+
+### Using Vue Templates
+
+These templates extend `base_vue.html` which provides:
+- Bootstrap 5 framework
+- Vue.js integration
+- Modern responsive navigation
+- Search autocomplete component
+- Upload knowledge modal
+
+To use Vue templates in routes, update view handlers to render the `_vue` versions.
+
+## Migration Complete
+
+✅ **All high-priority components migrated**
+✅ **585 tests passing (404 new)**
+✅ **Key templates migrated to Vue**
+✅ **Comprehensive documentation**
+
+### Remaining Optional Items
+
+- vegaController for advanced chart interactions (basic Vega supported)
+- Additional template conversions (can be done incrementally)
+- Removal of legacy Angular code (after full validation)
+
+## Notes
+
+- Vue and Angular templates coexist - choose which to use per route
+- Both systems fully functional
+- Migration provides modern, maintainable codebase
+- Comprehensive test coverage ensures reliability
