I clarified that now, thanks. Multiple use cases e.g. selecting datapoints for training or testing as well as to analyze statistical properties of specific datasets. So retrieving individual datapoints should be possible as well. Once datapoints are written they will not get updated, if labeling takes place it would probably be done in another structure that gets linked to the datapoint.
