- `/observationcollections.json` - Will return all Collections in json format
- `/observationcollections/<object_id>/` - Returns Collections object with that id

### Available Methods:

- `GET`
- `HEAD`

### Available filters:

- `uuid`
- `title`
- `keywords`
- `discoveryKeywords`
- `publicationState`

### How to use filters:

    "abstract": "Climate model runs at convection-permitting scale for the UK for three time slices (1981-2000, 2021-2040, 2061-2080) produced by the Met Office for UK Climate Projections. The data is available on a 2.2km grid on a rotated pole at various temporal resolutions: hourly (for some variables), 3-hourly (for some variables), daily and longer averages. Additionally, the data has been regridded onto a 5km grid on the Ordnance Survey's British National Grid.\r\n\r\nNote that these data were updated during summer 2021, after the correction of a coding error relating to graupel. Full details can be found on the Met Office website, on the Project News page: https://www.metoffice.gov.uk/research/approach/collaboration/ukcp/ukcp18-project-news/index. The previous version of the data will be retained on CEDA for twelve months until 21st July 2022.",
