Observation Instance
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`

The fields have been under permanent grassland management for more than 20 years with a species composition of >99% perennial ryegrass (Lolium perenne) and < 0.5% clover (Trifolium repens). The soil type is an imperfectly drained Eutric Cambisol (FAO classification) with a pH of 5.1 (in H2O), a clay fraction of 20-26% (Clayey Loam to Sandy Loam) and a soil organic carbon content of 4% (0-10 cm depth). The grassland is grazed by cows, ewes and lambs at different stocking densities and has been cut for silage in some years. The instrumentation sits on the boundary between two fields, labelled north and south, although the fenceline runs down from the NW to SE.", "keywords": "Easter Bush, CEH", "publicationState":
