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": "ESA Sea Level Climate Change Initiative (Sea_Level_cci): Collection of datasets of altimeter along-track high resolution sea level anomalies and associated trends in some coastal regions, v1.1",
    "abstract": "This dataset collection contains various along-track sea level anomaly products derived from satellite altimetry by the ESA Sea Level Climate Change Initiative project.\r\n\r\nTwo datasets containing along-track sea level anomalies derived from satellite altimetry have been derived; one containing data from the JASON satellites (JASON-1, JSON-2, and JSON-3), and the other from the RA2 instrument on ENVISAT and the Altika instrument on SARAL satellite missions.\r\n\r\nThese have been processed to produce high resolution (20 Hz, corresponding to an along-track distance of ~300m) sea level anomalies, in order to provide long-term homogeneous sea level time series as close to the coast as possible in six different coastal regions (North-East Atlantic, Mediterranean Sea, Western Africa, North Indian Ocean, South-East Asia and Australia).  \r\n\r\nThe products benefits from the spatial resolution provided by high-rate data, the Adaptive Leading Edge Subwaveform Retracker (ALES) and the post-processing strategy of the along-track (X-TRACK) algorithm, both developed for the processing of coastal altimetry data, as well as the best possible set of geophysical corrections.  \r\n\r\nAdditionally a database of coastal sea level anomalies and associated trends from Jason satellite altimetry, derived from the JASON sea level anomaly product is included.",
