- `/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`

    "abstract": "The Land Cover CCI has generated a number of data products as part of its Climate Data Research Package.  These consist of: \r\n\r\n- A new time series of consistent global LC maps at 300 m spatial resolution on an annual basis from 1992 to 2015;\r\n- 1 user tool for sub-setting, re-projecting and re-sampling the products in a way which is suitable to each climate model.\r\n- The full archive of AVHRR HRPT 1 km surface reflectance 7-day composites from 1992 to 1999;\r\n- The full archive of MERIS surface reflectance 7-day composites from 2003 to 2011 (300 m and 1 km resolution);\r\n- A PROBA-V 1 km time series of surface reflectance 7-day composites from mid March 2014 to end 2015;\r\n- 1 static map of open water bodies including ENVISAT ASAR data;\r\n-  3 global land surface seasonality products characterizing the vegetation greenness, the snow and the burned areas dynamics.\r\n\r\nIn the context of the CCI Open Data portal, a subset of these data products are held within the CEDA archive.   \r\n\r\nThe complete set of data products are available from the CCI Landcover team via their portal at: http://maps.elie.ucl.ac.be/CCI/viewer/",
