XASDB

XASDB stores and processes experimental X-ray absorption spectroscopy (XAS) data, enabling spectrum visualization, data processing, spectrum matching, and data sharing across XAS databases.

Key Features:

• Data Storage and Management: XASDB uses a MySQL table structure optimized for the unique nature of XAS data.
• Spectrum Visualization: Professional plotting tools present XAS spectra interactively.
• Data Processing: Tools for data normalization of raw XAS spectra are integrated in the platform.
• Spectrum Matching: XASMatch toolkit identifies the most similar spectra within the database to input spectra and ranks them with scores.
• Search and Download: Flexible searching and downloading options for spectra are provided.
• Data Sharing: An API interface facilitates sharing data with other XAS databases and users.

Scientific Applications:

• XAS Data Analysis: XASDB supports understanding of experimental X-ray absorption spectroscopy data through integrated visualization, processing, and matching capabilities.
• Standard Reference Identification: XASMatch enables identification of unknown spectra by matching against database entries containing 152 spectra of metals, oxides, and minerals standards measured at Beijing Synchrotron Radiation Facility.
• Cross-Database Integration: The API supports interoperability and data exchange with other XAS databases.

Methodology:

XASDB employs a MySQL database with a table structure designed for XAS data characteristics, integrates professional plotting tools for visualization, and incorporates XASMatch for spectrum similarity scoring and ranking.
