[ckan-dev] Organization hierarchy

Tue Aug 9 10:51:27 UTC 2016

Hi Stefan

Many thanks for your answer, I will start trying to implement a "before_index" and add a field to contain all the upstream organizations. In principle the organizational structure should be fixed but I am afraid how changes will affect the indexed datasets. For example if a children organization moves to other parent, one should change the contents of that field in every dataset and re-index it, maybe this already happens automatically.

In addition to the facets, I want that the organization hierarchy is shown in the breadcrumb navigation (ex. home/organizations/parent/child) and in the page of every organization if available, the children organizations and their datasets.

Best,
Lucia

Hi Lucia,

we used ckanext-hierarchy for opendata.swiss as well. All you have to do is to override the organization_tree.html template and add your customization. For the Swiss portal, we had to make sure, that the organizations are translated correctly (you can find the code here: https://github.com/ogdch/ckanext-switzerland/blob/master/ckanext/switzerland/templates/organization/snippets/organization_tree.html).

As for your problem of datasets belonging to multiple organizations: this is a rather hard problem. To enable this is CKAN core would require to rewrite a lot of code, as the authorization is connected to organization (i.e. as a member of an organization, you can edit its datasets). If this is more a display issue, I'd suggest to tweak the Solr index. The package controller interface has a method "before_index" that you can use to do this (see http://docs.ckan.org/en/latest/extensions/plugin-interfaces.html#ckan.plugins.interfaces.IPackageController.before_index). I would probably create a new field where you can save all organizations. In the end this shouldn't be hard, as it already works for groups and under the hood organizations are implemented as groups.

I'd be very interested in this kind of improvement, as this is a requirement we might encounter as well.

Best Regards Stefan

 Hi everyone,

I would like to have a hierarchical structure for my organizations so I used the extension https://github.com/datagovuk/ckanext-hierarchy. 

I plan to improve the display, that seems an easy task but if someone has already done some work I will be very grateful if it can be shared with me.

I also would like that the datasets from one organization also belong to the parent one. For example, I want that when you filter the datasets on the facets by one organization, all the datasets belonging to its children appear.

Any hints how to achieve this? One solution would be to allow datasets to belong to more than one organization, alternatively I guess one could configure the indexing for Solr.

Many thanks in advance for your help.  

Best,
Lucia
