Allow personalization of SDDI CKAN via config variables

[BWibo]

Feature description

Currently, on a few settings, e.g. the about text are expose via configuration variables.

Other important customizations are not accessible via variables, e.g.:

• Default groups and organizations
• Background image (see below)
• Text below intro text (see below)

Suggested solution

Expose these options as config variables. This has to be done in the ckanext-grouphierarchy-sddi:

• Default groups and organizations: Path to groups_orga.json. This might require to have separate files for main categories + topics and organizations, hence two different config parameters. The default value should point to the SDDI default config files.
  • It should be possible to specify the config files path as a) URL to an external file somewhere on the web, b) as file path inside the ckan container. The file needs to be structured like this.
  • Is a similar mechanism possible for the icons of groups, topics usw.?
• Background image (see below): Path to background.jpg
• Text below intro text (see below): Text to be show.
