…sium tutorial Phase 1 (documentation only - no code changes): - Added "Why Path 1 and Path 2?" explanation with clear diagrams - Added full relationship map showing Agent and IdentifiedConcept paths - Added Eric's query pattern analysis from open-context-py - Documented all 4 query functions with path requirements and summary table - Added local parquet file access instructions for faster development Key improvements: - Users now understand the property graph structure before seeing queries - Clear distinction between geographic paths vs agent/concept paths - Explains INNER JOIN implications (both paths required) - Documents reverse query pattern (geo → samples) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
… parquet_cesium tutorial
Implemented Eric Kansa's combined query function that unifies Path 1 and Path 2
with richer sample metadata. This complements the existing separate path queries
by providing a comprehensive view of all samples at a location.
New features:
- Added get_samples_at_geo_cord_location_via_sample_event() function
- Combines Path 1 (direct event location) and Path 2 (via site) using UNION
- Returns enriched metadata: sample_pid, sample_label, sample_description,
thumbnail_url, alternate_identifiers, event_label, site_label, site_pid
- Uses LEFT JOIN for sites in Path 1 (optional), INNER JOIN in Path 2 (required)
- Orders results by thumbnail availability for better visual browsing
- Added selectedSamplesCombined reactive cell with loading state management
- Added new display section "Combined Samples at Location" with documentation
- Added combinedLoading flag to track query state
Architecture:
- Preserves existing get_samples_1() and get_samples_2() functions unchanged
- Adds parallel implementation for comparison and exploration
- Maintains consistent pattern with existing loading indicators and error handling
This enables users to see both simple (Path 1/Path 2 separate) and comprehensive
(combined with rich metadata) views of samples at clicked locations.

- Set initial camera view to Italy bounding box (6.6-18.8°E, 36.6-47.1°N) - Configure Home button to reset to Italy instead of global view - Use postRender event listener to apply camera after first render - Prevents resize/tab visibility issues with early camera positioning This provides a more useful default view for the OpenContext dataset, which is heavily concentrated in Mediterranean archaeological sites. Also update .gitignore to exclude Quarto intermediate files (*.quarto_ipynb). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
- Center on PKAP Survey Area coordinates (34.987406°N, 33.708047°E) - Use 0.3° padding around point for better context - Update Home button to reset to PKAP instead of Italy - Add OpenContext source URL in comment for reference PKAP (Palaepaphos-Kouklia Archaeological Project) is a better demonstration site as it showcases the multi-location survey pattern with 15,446 events across 544 different geographic coordinates within the survey area. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
MAJOR FEATURE: Geographic locations now color-coded by semantic role Query Changes: - Add CTE to classify GeospatialCoordLocations by usage type - Join with edges to determine sample_location vs site_location usage - Return location_type field: 'sample_location_only', 'site_location_only', 'both' Visualization Changes: - Blue (3px): sample_location_only - precise field collection points (Path 1) - Purple (6px): site_location_only - administrative site markers (Path 2) - Orange (5px): both - dual-purpose locations (~10k geos) Implementation Details: - Use Cesium.Color.fromCssColorString() for hex colors (#2E86AB, #A23B72, #F18F01) - Conditional styling per point based on location_type - Updated Data tab table header to show location_type column Documentation Updates: - Changed "Future Enhancement" to "✅ IMPLEMENTED" - Added color legend with emoji indicators - Updated SQL example to use 'nodes' table (not 'pqg') - Documented performance impact (minimal) - Listed future enhancements (UI filters, Site Explorer Mode) Benefits: - Makes Path 1 vs Path 2 distinction visually concrete - Users can SEE semantic difference between precise and administrative locations - Transforms visualization into pedagogical tool for understanding iSamples model 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
