ckanext-saerischema

This is a CKAN plugin to implement additional metadata fields (schema) specifically for SAERI.

It displays the fields for entering metadata on the dataset create/update page and displays the (non-empty) fields on the dataset display page. Some of the SAERI fields re-use existing CKAN metadata fields (eg. Description which is renamed to Abstract, Tags which is renamed to Keywords, Topic Category becomes a CKAN group which is displayed as Theme) and the rest are additional.

One unique feature is that the bounding box which the user enters into the four fields (east, west, north, south) is converted into a GeoJSON format and stored in the CKAN extra ‘spatial’ field which allows the user to search for datasets by specifying an area on a map. The Spatial Reference System is used to determine whether the coordinates are lat,long degrees or metres in a UTM projection. At the moment only certain SRS are supported: * “WGS84”, “UTM 21S WGS84” (becomes epsg:32721) * “UTM 28S WGS84” (becomes epsg:32728) * “World Mercator WGS84 Datum” (becomes epsg:3395) * “TM CM 60W” (becomes epsg:6703) * “Montserrat 1958 British West Indies Grid” (becomes epsg:2004).

There is a mapping between the metadata field called ‘topic_category’ and the CKAN concept of Groups. Groups are used to group together all datasets which share a common theme, eg. Biota, and so is synonymous with topic category. (However, normally, ckan datasets can be a member of multiple groups but SAERI topic category is only a single selection). The schema plugin uses the SAERI extra metadata field ‘topic_category’ to force the dataset to be a member of the corresponding ckan group automatically. The groups must already exist! (see Installation and tools directory). If the user manually adds a dataset to multiple other groups this will be allowed but if the dataset metadata is subsequently updated then the group membership will be reset to the topic_category group only.
