create
```
public static DatasetDescription create(Query query)
```
Create a dataset description, given a query. If the query does not have a dataset description, return null.

create
```
public static DatasetDescription create(Context context)
```
Create a dataset description, given a context. If the context does not have a dataset description, return null. The context uses the key ARQConstants.sysDatasetDescription.
