 For development, `webdataset` supports data streaming and does not need any local data (depending on your internet connection).
 Code for data loading via webdataset is provided in the [GitHub repository](https://github.com/DLR-MF-DAS/SSL4EO-S12-v1.1).
 
+## Metadata

+The `sample_id` is similar to the v1 dataset. `S2_time_{i}` is shared between S2L1C, S2L2A, S2RGB, and NDVI. LULC is augmented with the cloud and ice/snow mask from this timestamp.
