## Use full names for data model concepts

DBnomics data model defines concepts such as _provider_, _dataset_, _time series_, _dimension_ or _observation_. Do not abbreviate those terms.

Examples:

- use `dataset_info` instead of `ds_info`
- use `dimensions` instead of `dim_dict`
- use `current_observation` instead of `current_obs`

## Handle the plural of time series

In English, a _time series_ is invariable.

In order to distinguish a single series from a list of series:

- name a single series `series`
- name a list of series `series_list`
