# WSI test data
WSI test slides for the [opentile](https://github.com/imi-bigpicture/opentile), [wsidicomizer](https://github.com/imi-bigpicture/wsidicomizer) and [wsidicom](https://github.com/imi-bigpicture/wsidicom) test suites, mirrored here for fast, reliable CI downloads. Each slide folder holds a self-contained `metadata.json`; the root `index.json` is the aggregate. Each slide's original source, license, credit and attribution are in its `metadata.json`.
