The dataset `.json` annotations are great for dataloading, however it would be really helpful to have more meaningful description of the entries. For example in LTA task, what is a difference between:

```auto
'interval_{start|end}_{sec|frame}'

```

and

```auto
'action_clip_{start|end}_{sec|frame}'

```

Or similarly, how are the data such as

```auto
['annotations'][idx]['noun']

```

formatted.

This is a dummy example, but most tasks have somewhat ambiguous annotations whose meaning is only accessible through trial and error and analysing benchmark codes/submissions. It would be very helpful to have these descriptions in the schema definitions.
