list_products

List products (datasets) in Source Cooperative with hybrid S3 + API approach. DEFAULT: Uses S3 direct scan (fast, includes ALL products with file counts). Set include_unpublished=False for published-only with rich metadata from API. Args: account_id: Filter by specific account. REQUIRED for S3 mode (default). If None with include_unpublished=False, lists published from all accounts. featured_only: Only return featured/curated products (API mode only). include_unpublished: If True (default), scan S3 for ALL products including unpublished. If False, use API for published products with rich metadata. include_file_count: Count files in each product (default True, only in S3 mode). Returns: S3 mode (default): Basic info (product_id, s3_prefix, file_count) - fast! API mode: Rich metadata (product_id, title, description, dates) - slower Performance: - S3 mode (default): ~240ms, includes unpublished products + file counts - API mode (include_unpublished=False): ~500ms, rich metadata, published only Examples: >>> # ALL products with file counts (DEFAULT - fast!) >>> await list_products(account_id="youssef-harby") [ {"product_id": "exiobase-3", "source": "s3", "file_count": 1000, ...}, {"product_id": "egms-copernicus", "source": "s3", "file_count": 53, ...}, ... ] >>> # Published products with rich metadata (API mode) >>> await list_products(account_id="youssef-harby", include_unpublished=False) [{"product_id": "egms-copernicus", "title": "...", "description": "...", ...}] >>> # Fast mode without file counts >>> await list_products(account_id="youssef-harby", include_file_count=False) [{"product_id": "exiobase-3", "source": "s3", ...}] >>> # Featured products only (requires API mode) >>> await list_products(featured_only=True, include_unpublished=False) [{"product_id": "gov-data", "featured": 1, ...}]

get_product_details

Get comprehensive metadata for a specific product. Always includes README content if found in the product root directory. Args: account_id: Account ID (e.g., "harvard-lil") product_id: Product ID (e.g., "gov-data") Returns: Full product metadata including account info, storage config, roles, tags Always includes 'readme' field with content and metadata (if README exists) Example: >>> await get_product_details("harvard-lil", "gov-data") { "title": "Archive of data.gov", "description": "...", "account": {"name": "Harvard Library Innovation Lab", ...}, "readme": { "found": true, "content": "# Archive of data.gov...", "size": 5344, "path": "harvard-lil/gov-data/README.md" }, ... }

list_product_files

List all files in a product with full S3 paths ready for analysis. Optionally show a hierarchical tree visualization (optimized for LLM tokens). Args: account_id: Account ID product_id: Product ID prefix: Optional prefix to filter files (subdirectory path) max_files: Maximum files to return (default 1000) show_tree: If True, return tree visualization only (more token-efficient, default True) Returns: Dict with either files list OR tree visualization (not both to save tokens) Example (List mode - detailed metadata): >>> result = await list_product_files("harvard-lil", "gov-data", "metadata/") >>> print(result["files"][0]) { "key": "harvard-lil/gov-data/metadata/metadata.jsonl.zip", "s3_uri": "s3://us-west-2.opendata.source.coop/harvard-lil/gov-data/metadata/metadata.jsonl.zip", "http_url": "https://data.source.coop/harvard-lil/gov-data/metadata/metadata.jsonl.zip", "size": 1012127330, "last_modified": "2025-02-06T16:20:22+00:00" } Example (Tree mode - token optimized): >>> result = await list_product_files("harvard-lil", "gov-data", show_tree=True) >>> print(result["tree"]) s3://us-west-2.opendata.source.coop/harvard-lil/gov-data/ ├── README.md (5.2 KB) → s3://...README.md ├── metadata/ │ └── metadata.jsonl.zip (965.4 MB) → s3://...metadata.jsonl.zip └── data/ └── datasets.parquet (128.5 MB) → s3://...datasets.parquet Example (Partitioned data - smart summarization): >>> result = await list_product_files("account", "product", show_tree=True) >>> print(result["tree"]) s3://us-west-2.opendata.source.coop/account/product/ ├── year={1995,1996,...,2007 (13 total)}/ [partitioned] │ └── format={ixi,pxp}/ [partitioned] │ └── matrix={F_impacts,F_satellite,Y,Z}/ [partitioned] │ └── data.parquet (5.1 MB) Note: Shows first,second,...,last (total) for >10 values; lists all for ≤10 Tree mode saves ~70% tokens + smart partition detection saves 96%+ more

get_file_metadata

Get metadata for a specific file without downloading it. Uses obstore's head operation for efficient metadata retrieval. Args: path: S3 URI (s3://...) or relative path (account_id/product_id/file) Returns: File metadata: size, content-type, last-modified, etag, URLs Example: >>> await get_file_metadata("harvard-lil/gov-data/README.md") { "key": "harvard-lil/gov-data/README.md", "content_type": "binary/octet-stream", "content_length": 5344, "last_modified": "2025-02-06T16:29:24+00:00", ... }

search

Search for products across ALL accounts with smart fuzzy matching. Handles typos, partial matches, and incomplete words using 60% similarity threshold. **Hybrid Search** - Automatically searches across: - All 94+ organizations - ALL products (published + unpublished) - All fields: title, description, product_id Published products: Full metadata (title, description, product_id) Unpublished products: product_id only (no title/description available) Args: query: Search keyword (supports typos and partial matches) Returns: **Top 5** matching accounts or products (sorted by relevance score) Performance: ~5-8s (parallel 2-level S3 scan + top 5 API enrichment) Performance breakdown: - S3 parallel listing: ~2.4s (94 accounts + 354 products) - Fuzzy matching: <1s (in-memory processing) - API enrichment: ~2-5s (only top 5 results) **11x faster** than sequential approach (was ~27s) **Uses 2-level delimiter listing** (not full recursive scan) Examples: >>> # Exact match >>> results = await search("climate") >>> # Fuzzy match (handles typos) >>> results = await search("climte") # Finds "climate" >>> results = await search("exiopase") # Finds "exiobase-3" (includes unpublished!) >>> # Partial match >>> results = await search("geo") # Finds "geospatial", "geocoding", etc. >>> # Result formats >>> print(results[0]) # Account match { "type": "account", "account_id": "harvard-lil", "match_string": "harvard-lil", "search_score": 9.5, "similarity": 0.95, "matched_fields": ["account_id"] } >>> print(results[1]) # Product match { "type": "product", "account_id": "youssef-harby", "product_id": "exiobase-3", "match_string": "youssef-harby/exiobase-3", "title": "", # Empty for unpublished products "description": "", # Empty for unpublished products "search_score": 8.2, "similarity": 0.82, "matched_fields": ["product_id"] }
