[Introduction](#introduction)\n2. [Package Contents](#package-contents)\n3. [JSON Schema for Spectral Datasets](#schema)\n4. [License](#license)\n\n## Introduction\nThis is the data repository for the RAW to ACES Utility or `rawtoaces` (https://github.com/AcademySoftwareFoundation/rawtoaces), a software package that converts digital camera RAW files to ACES container files containing image data encoded according to the Academy Color Encoding Specification (ACES) as specified in [SMPTE 2065-1](http://ieeexplore.ieee.org/document/7289895/). The output image complies with the ACES Container specification [(SMPTE S2065-4)](http://ieeexplore.ieee.org/document/7290441).\n\n## Package Contents\n\nThe repository contains the following:\n\n* [`data/camera/`](./data/camera) - camera spectral sensitivities\n* [`data/illuminant/`](./data/illuminant) - light source spectral power distribution\n* [`data/cmf/`](./data/cmf) - color matching functions (CIE-1931)\n* [`data/training/`](./data/training) - 190 training patch dataset\n\t\n## JSON Schema for Spectral Datasets\n\nThe schema takes its roots in [IES TM-27-14](http://www.techstreet.com/standards/ies-tm-27-14?product_id=1881073) but implements support for multiple spectral datasets while adopting [JSON](http://www.json.org/) over [XML](https://www.w3.org/TR/REC-xml/) for the simplicity of its grammar.\n\n`rawtoaces` expects the spectral dataset to have the following shape: **(380, 780, 5)**, i.e. starting from 380nm and ending at 780nm with a 5nm interval/bin size.\n\nThe attributes are defined as follows:\n\n- `header`\n    - `schema_version`\n        - **description**: *Required*, schema version of the current document.\n        - **type**: `\"string\"`\n    - `comments`\n        - **description**: *Optional*, additional information for the spectral dataset.\n        - **type**: `[\"string\", \"null\"]`\n    - `description`\n        - **description**: *Required*, description of the spectral dataset.\n        - **type**: `\"string\"`\n    - `document_creation_date`\n        -
