Get a list of Collections objects. Collections have a 1:1 mapping with Observations.

### Available end points:

- `/observationcollections/` - Will list all Collections in the database
- `/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:

- `/observationcollections/?uuid=ab4ca8d019d148f78afba1cd20872bdd`

    "title": "NOCS (National Oceanography Centre, Southampton) Flux Datasets: marine surface meteorology, freshwater and heat fluxes.",
    "abstract": "The National Oceanography Centre Southampton (NOCS) produced a collection of Surface Flux Datasets which contains estimates of the following parameters (including uncertainty) on a 1° monthly mean grid for the global ice-free ocean:\r\n\r\n- Air temperature (at 10 m)\r\n- Specific Humidity (at 10 m)\r\n- Wind Speed (at 10 m)\r\n- Sea level pressure\r\n- Sea surface temperature (bulk)\r\n\r\n- Latent heat flux\r\n- Sensible heat flux\r\n- Net longwave radiation\r\n- Net shortwave radiation\r\n\r\nThe datasets are:\r\n\r\nNOC1.1 - National Oceanography Centre Surface Flux Climatology (version 1.1) - 1973-2005\r\nNOC1.1a - Adjusted National Oceanography Centre Surface Flux Climatology (version 1.1a) -1973-2005\r\nNOC2.0 - National Oceanography Centre Surface Flux Climatology (version 2.0) - 1973-\r\n\r\nNote that the NOC1 climatology was previously referred to as the Southampton Oceanography Centre (SOC) flux climatology and was renamed when the SOC became the NOC. The SOC climatology existed in two versions: the 'Original' set of fields and an 'Adjusted' set in which closure of the ocean heat budget was achieved using inverse analysis. These have now become:\r\n\r\nNOC1.1 - Previously the 'Original' SOC climatology including Heat flux and wind stress fields, Freshwater flux fields and Meteorological fields\r\n\r\nNOC1.1a - Previously the 'Adjusted' SOC climatology (climatological monthly fields) including Heat flux fields only.\r\n\r\nThese data can be used for many purposes, including assessing the performance of numerical models, assessing the measurements we get from satellites and understanding how the ocean and atmosphere interact in recent decades.\r\n\r\nFor background information on Heat Fluxes, please see links under Docs.\r\n\r\nFunding has been received from the Hadley Centre, UK Meteorological Office for the production and analysis of this collection of data.",
