Observation Instance – Django REST framework

Get a list of Observation objects.

### Available end points:

- `/observations/` - Will list all Results in the database
- `/observations.json` - Will return all Results in json format. This can
also be achieved by using the accept header. `application/json`
- `/observations/<object_id>/` - Returns Results object with that id

### Available Methods:

- `GET`
- `HEAD`

### Available filters:

- `title`
- `uuid`
- `keywords`
- `status`
- `result_field`
- `discoveryKeywords`
- `updateFrequency`
- `nonGeographicFlag`
- `publicationState`
- `permissions`

### How to use filters:

These filters can be used like django query filters using __ for related model relationships.

- `/observations/?uuid=d594d53df2612bbd89c2e0e770b5c1a0`
- `/observations/?status=completed`
- `/observations/?results_field__dataPath__startswith=/neodc/esacci`
- `/observations/?discoveryKeywords__name=ESACCI`
- `/observations/?nonGeographicFlag=True`

Filters can be stacked to build an 'AND' relationship. E.g.

- `/observations/?publicationState__in=published,citable&nonGeographicFlag=True`
- `/observations/?publicationState__in=published,citable&discoveryKeyword__name=NDGO0003`

    "abstract": "This dataset contains outputs from a three year ocean (Nucleus for European Modelling of the Ocean (NEMO)) model simulation over the Sri Lanka region, from 2019 to 2021. The model is at 1/60 degree resolution, based on General Bathymetric Chart of the Oceans (GEBCO) bathymetry. It is forced with Copernicus Marine Environment Monitoring Service (CMEMS), GLOBAL_MULTIYEAR_PHY_001_030-TDS, derived ocean boundary conditions and ERA5 atmosphere. The data are daily averages saved in monthly grid-t, grid-u, and grid-v files. The model configuration is named SRIL34, and was part of the X-Press Pearl Disaster Nitrogen Modelling project. The outputs were generated under the Climate Linked Atlantic Sector Science (CLASS) and the South Asian Nitrogen Hub (SANH; NE/S009019/1) projects.",
