The INFRA-ART Spectral Library is an open-access resource, implemented according to the FAIR principles.
The INFRA-ART Spectral Library is managed by domain experts within the National Institute for Research and Development in Optoelectronics (INOE 2000).
The INFRA-ART Spectral Library was designed as a digital support tool for heritage research professionals working with spectroscopic techniques. The database covers spectral data on heritage-related materials.
The library currently contains over 1,000 different materials.
The database includes a broad range of art-related materials commonly found in works of art, categorized into fourteen distinct classes. For full details, please refer to the Data Types and Metrics section.
New samples are periodically added to the database as new reference materials become available.
Currently, the database includes only reference materials. However, mockup samples are planed to be included in the future.
The library integrates several types of spectroscopic data, including:
For full details on the equipment used and the experimental conditions for data acquisition and processing, please refer to our Experimental setup page.
The largest spectral collections are ATR-FTIR and XRF data, each with over 900 spectra. These datasets make up the majority of the library, followed by smaller collections like Raman and SWIR spectra.
Yes, we plan to integrate new data types such as LIBS (Laser-Induced Breakdown Spectroscopy) and FORS (Fiber Optic Reflectance Spectroscopy) in the future.
Access to the data and services on this website is open and free of charge to all users.
Currently, spectral data files are not available for direct download.
External users can request access to the data files by submitting a File Access Request Form. For more information, please refer to our Data Access Policy.
Yes, the INFRA-ART Spectral Library follows the FAIR Guiding Principles, supporting cross-disciplinary research and enabling the reliable reuse of data for research, innovation, and educational purposes.
The data is licensed under the Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0) license. This means you can share and adapt the data for non-commercial purposes; provide appropriate attribution and not suggest that the licensor endorses you. For commercial use, you must seek separate authorization. Please refer to our Terms of Use for further details.
No, the data cannot be used for commercial purposes without prior written permission from the INFRA-ART project coordinator and a legal agreement. Please refer to our Data Access Policy for further details.
Yes, the metadata associated with the datasets in the INFRA-ART Spectral Library is licensed under the Creative Commons Zero (CC0) license, allowing free usage, sharing, and modification without restrictions. However, we encourage proper attribution when using the metadata.
The spectral data is typically provided in open, widely used formats such as .CSV (Comma-Separated Values) and .TXT (Text File).
If you require the data in a different format, please contact us at infraart@inoe.ro. We will evaluate your request and, if feasible, provide the data in the requested format.
Except for XRF, which is available as raw data, all other data types are processed as detailed in the Experimental setup.
If you use data from the INFRA-ART Spectral Library in your publications or presentations, please cite the following reference:
The reference materials included in the INFRA-ART Spectral Library are carefully selected for their quality. They are sourced from reputable manufacturers and suppliers, ensuring their authenticity and suitability for research purposes.
The INFRA-ART Spectral Library undergoes rigorous curation by domain experts to ensure the data's quality, transparency, and usability. For more information, please refer to our Data Curation Policy.
If you identify any errors or discrepancies in the data, please notify us at infraart@inoe.ro and we will make reasonable efforts to correct them.
Currently, only authorized data curators from the National Institute for Research and Development in Optoelectronics (INOE 2000) can deposit data into the repository. External users are not permitted to submit data at this time.
No, users granted access to the data are not permitted to share, redistribute, or re-upload the data to third parties without explicit permission from the INFRA-ART project coordinator.
