Commits: ecae27abb750013db702f675fc380c8c23cd9160; fec5f3488fcca5b80572d1793923467bf2efc7d8; a83f53af7b19a9c23d33fa95e8c4aeb932510e23. - bids-specification: Metadata Schema Flexibility and Validation for SpectrometerFrequency and ResonantNucleus. Introduced flexible types (single value or array) and validation rules to improve data schema consistency and support multi-nuclei setups. Commits: 5dbd969aa36aff102215e7af17df133a9ba8893a; b0332610034c0e45717fd565b8103da8f1cfe720; afe97c388cdc3f83f1be109de4bbef8184c1d3f1; 0b45139ff4d2c220b42a741fe7a0c5916bef6e1b. - bids-website: BIDS Documentation Enhancements: Update supported modalities and DOI abbreviation. Updated documentation to reflect newly supported modalities (ASL, NIRS, motion, MRS) and refined DOI abbreviation in the BIDS reference. Commit: 79bb5c6df1763702a6e755092252f1aa8a52551d. Major bugs fixed (implied as part of documentation and reference updates): - Eliminated duplicate optional fields in dataset descriptions and corrected citation references in the introduction material. - Implemented stricter schema rules for frequency and nucleus fields to prevent inconsistent multi-nuclei entries. Overall impact and accomplishments - Improved data discoverability and accuracy for public archives through streamlined metadata and keyword optimization. - Strengthened data integrity and scalability by enabling multi-valued metadata fields for spectrometry-related data and validating against min/max constraints. - Enhanced user guidance and standards adoption by keeping documentation in sync with current modalities and reference conventions across both the specification and website. Technologies/skills demonstrated - Documentation best practices (Markdown) and citation management. - JSON/YAML schema design and validation (SpectrometerFrequency, ResonantNucleus). - Cross-repo collaboration and release-ready documentation updates. - Familiarity with BIDS modalities and reference conventions.
