 # About
-PD12M was built and curated with [Source.Plus] (htts://source.plus) with the aim of resolving many of the data quality issues that arise in web-scraped training data: the presence of copyrighted material, low quality images and captions, violent or nsfw content, PII, decaying dataset quality via broken links, etc.

 PD12M consists of entirely public domain and CC0 licensed images, with automated recaptioning of image data, and quality and safety filtering. Images in PD12M are also hosted on dedicated cloud storage, separate from the original image hosts, to avoid placing an undue burden on those hosts or impacting services for regular users. This also ensures the dataset remains wholly intact over its lifetime.

-- `s3_key`: The S3 file key of the image.
 - `caption`: A caption for the image.
-- `md5_hash`: The MD5 hash of the image file.
-- `mime_type`: The MIME type of the image file.
 - `width`: The width of the image in pixels.
