Open Data

PID Metadata Dump

As part of our commitment to FAIR data principles, pid4cat will provide regular dumps of PID metadata. These dumps will:

  • Be available in multiple formats (JSON, RDF, CSV)
  • Include all non-sensitive metadata fields
  • Be licensed under CC0 1.0 Universal Public Domain Dedication
  • Include comprehensive documentation
  • Be assigned their own pid4cat identifiers

Availability

The metadata dumps will be available through:

  1. Direct download from the pid4cat website
  2. API access for programmatic retrieval
  3. Integration with metadata aggregators

Usage

The metadata dumps can be used for:

  • Research on PID usage patterns
  • Integration with discovery services
  • Network analysis of PID relationships
  • Development of value-added services

PID Graph Integration

pid4cat is designed to integrate with the broader PID Graph ecosystem. The PID Graph connects different types of persistent identifiers, creating a rich network of scientific and scholarly entities.

pid4cat contributes to this ecosystem by:

  1. Including relationships to other PIDs in its metadata
  2. Using standard relationship types
  3. Exposing metadata in machine-readable formats
  4. Supporting linked data principles

Analytics and Reporting

The open data approach enables various analytics and reporting functions:

  1. Usage statistics: Tracking resolution requests and metadata access
  2. Growth metrics: Monitoring the growth of pid4cat identifiers over time
  3. Connectivity analysis: Analyzing relationships between pid4cat identifiers and other PIDs
  4. Community impact: Assessing the impact of pid4cat on the research community

These analytics will be made available through regular reports and an interactive dashboard.
