Research and Development

Data Lineage (Provenance)

  • Tracks data origins and transformations to ensure transparency, integrity, and traceability.
  • Key for error detection, regulatory compliance, and decision-making trustworthiness.
  • Challenges: Scalability, privacy, and cross-platform alignment.

Harmonization of Data from Heterogeneous Sources

  • Standardizes and integrates data from diverse formats and systems.
  • Uses ETL, data cleaning, and semantic integration.
  • Challenges: Managing quality, metadata consistency, and structural differences.

Use of Metadata to Automate Data Management

  • Automates data discovery, quality management, and governance using metadata.
  • Key for indexing, policy enforcement, and consistency monitoring.
  • Challenges: Ensuring metadata consistency and managing scale.

Rich Descriptions of Sensing Devices and Actuators

  • Provides detailed specs on sensors and actuators (e.g., type, range, precision).
  • Crucial for understanding device impact on data accuracy and system performance.
  • Challenges: Keeping descriptions up-to-date and ensuring interoperability.

Usage of Sensing Devices and Actuators by Instruments

  • Focuses on how sensors and actuators interact with instruments for data collection and control.
  • Key for integration, data flow, calibration, and maintenance.
  • Challenges: Interoperability, accuracy, and real-time performance.
