Collections are a new way to explore related datasets together. Instead of navigating datasets individually, collections group them by theme and apply smart filters to show you exactly what matters.

What Are Collections?

A collection is a curated set of datasets organized around a specific use case. For example, the "One Bag Travel" collection includes:

  • Travel Bags - Carry-on compliant bags
  • Reddit Mentions - Community discussions
  • Airline Limits - Baggage restrictions

Each collection has its own landing page at /c/{collection}/ where you can see all available datasets and jump directly to the one you need.

Smart Filtering

When you view a dataset through a collection (like /d/onebag/?c=onebag), relevant filters are applied automatically:

  • Scoped to what matters: Only see bags suitable for one-bag travel, not all bags in the database
  • Filter options adapt: The filter sidebar shows only options relevant to the current collection
  • Clear all respects scope: Clearing filters resets to the collection's scoped view, not everything

Flexible Access

Collections don't lock you in:

  • Direct access still works: Visit /d/onebag/ to see all items without collection filters
  • Context preserved: Navigate between datasets and the ?c= parameter keeps your collection context
  • Back button works: Return to your collection's dataset list with one click

New Navigation

The header navigation is now collection-aware:

  • With collection context: Shows "One Bag Travel › Travel Bags | Reddit Mentions | Airline Limits"
  • Without collection: Shows all datasets across all collections
  • Active highlighting: Current dataset is highlighted in the tabs

Try It

Visit /c/onebag/ to see collections in action. Click any dataset card to explore with collection-specific filters automatically applied.

What's next? We're working on search functionality in the header to quickly find collections and datasets, plus more collection-specific features.
