Federated Catalog

Discover and access data assets across the entire dataspace.

The Federated Catalog serves as a marketplace for all available data assets within the DLR Dataspace. As a federated system, it allows you to browse and search for assets not only from your organization but from all participating organizations that have shared assets with the dataspace.

Understanding the Federated Catalog

The Federated Catalog is a core component of the DLR Dataspace that aggregates asset information from all participating connectors:

  • Comprehensive view - See all available assets from every participant who has made offers
  • Real-time updates - The catalog continuously updates as new offers are created or existing ones are modified
  • Policy-aware browsing - Only see assets that your organization has permission to access based on policies

Search Functionality

The powerful search functionality helps you find exactly what you need:

  • Keyword search - Search asset names, descriptions, and metadata
  • Provider filtering - Find assets from specific organizations or connectors
  • Type filtering - Filter by file types, formats, or categories
  • Advanced filters - Filter by date added, size, and other attributes

Asset Browsing

The catalog presents assets in an easy-to-browse format with rich metadata:

  • Preview options - Quick preview of compatible file types
  • Detailed view - Click on any asset to see complete metadata and usage terms

Available Asset Types

The catalog includes various types of data assets: - CSV Dataset - JSON Data
- Images - Documents

Asset Information

Each asset in the catalog displays essential information to help you evaluate its relevance:

  • Asset name and description - Clear identification of what the asset contains
  • Provider information - Organization that owns and offers the asset
  • File type and size - Format and storage requirements
  • Created/updated dates - Timeline information for version tracking
  • Associated policy - Usage restrictions and access conditions
  • Additional metadata - Custom tags and categorization

The catalog offers sophisticated filtering capabilities to help you find relevant assets:

  • Organization filters - Find assets from specific data providers

Pro Tip

The Federated Catalog is constantly evolving as new assets are added. Check back regularly or set up notifications to stay informed about new data that might be relevant to your projects. In the future, semantic search capabilities will be added to help you find assets based on content similarity and usage patterns, making discovery even more powerful.
