What problem does it solve?
This Skill provides a comprehensive guide and set of tools for efficiently finding, querying, and managing data within the Mu2e experiment's modern data handling stack, replacing legacy systems.
Core Features & Use Cases
- Data Discovery: Query datasets and files using the
metacat command-line tool.
- Metadata Management: Understand and work with file naming conventions, namespaces, and Data Identifiers (DIDs).
- Data Location & Access: Find file locations on dCache (tape, disk, scratch) and generate URLs for access.
- Data Movement: Prestage files from tape to disk and upload personal files to dCache.
- Use Case: A researcher needs to find all simulation files for a specific run, check their storage location, and if they are on tape, request them to be prestaged for analysis.
Quick Start
Use the finding-data-metacat skill to list all production datasets.
