ckanext-msl_ckan

This extension contains configurations and templates for the EPOS MSL CKAN portal. The use of this extension is depended on several other extensions as described in the requirements section. Reusable functionality has been placed within the msl_ckan_util extension.

Requirements

This extension has been developed and tested with CKAN version 2.9.*

This extension requires the following other extension to be installed and activated:

CKAN extension Plugin
ckanext-scheming scheming_datasets
ckanext-scheming scheming_groups
ckanext-scheming scheming_organizations
ckanext-msl_ckan_util msl_ckan
ckanext-msl_ckan_util msl_custom_facets
ckanext-msl_ckan_util msl_repeating_fields

TODO: Add links to extension repos

Installation

TODO: Add any additional install steps to the list below. For example installing any non-Python dependencies or adding any required config settings.

To install ckanext-msl_ckan:

  1. Activate your CKAN virtual environment, for example:

    . /usr/lib/ckan/default/bin/activate

  2. Clone the source and install it on the virtualenv

         git clone https://git.science.uu.nl/epos-msl/epos-msl.git
     cd ckanext-msl_ckan
     pip install -e .
     pip install -r requirements.txt

  3. Add msl_ckan to the ckan.plugins setting in your CKAN config file (by default the config file is located at /etc/ckan/default/ckan.ini).

  4. Restart CKAN.

SOLR changes

The SOLR schema needs to be updated to use the additional fields that are used by the schemas within msl_ckan. The currently used schema is available at /config/solr/schema.xml.

Within the solrconfig.xml make sure that the <str name="q.op"> setting is set to AND for the select request handler:

  <requestHandler name="/select" class="solr.SearchHandler">
<!-- default values for query parameters can be specified, these
     will be overridden by parameters in the request
  -->
<lst name="defaults">
  <str name="echoParams">explicit</str>
  <int name="rows">10</int>
  <str name="mm">1</str>
  <str name="q.op">AND</str> <----
  ...

Config settings

This extension includes several configuration files that are used by other extension required by this project. To make the correct links to the other extensions/plugins the following lines should be added to the ckan.ini.

Load plugins

ckan.plugins in the ckan.ini should contain the following plugins:

  msl_ckan
  scheming_datasets
  scheming_groups
  scheming_organizations 
  msl_custom_facets
  msl_repeating_fields

Make sure to keep the above order of plugin declaration in the ckan.ini. The order of plugin loading determines the order of execution of hooks and usage of templates.

general settings

the following line should be added to within the [app:main] section:

  search.facets.limit = 10000

plugin specific settings

Keep in mind that all plugin specific settings should be added within the same block of settings as the ckan.plugins section within the clan.ini!

To use the schemas as included within this extension by the scheming plugin the following lines should be added to the ckan.ini file:

  scheming.dataset_schemas = ckanext.msl_ckan:schemas/datasets/data_publication.yml ckanext.msl_ckan:schemas/datasets/labs.json
  scheming.organization_schemas = ckanext.msl_ckan:schemas/organizations/organization.json

To use the included facet configuration:

  mslfacets.dataset_config = ckanext.msl_ckan:config/facets.json

To use the included index fields configuration:

  mslindexfields.field_config = ckanext.msl_ckan:config/msl_index_fields.json

For retrieving keyword information an endpoint for the service must be defined:

  mslvocabularies.endpoint_root = http://epos.test:89/api/vocabularies (Sample url)

Adjusting settings within CKAN

Some texts and settings have to be adjusted by signing in as admin within the portal. The default username and password depend on the installation type. It is recommended to change the default credentials after installation.

Generating an API key

Go to your profile in the top bar and click on manage. Within this form click on the Regenerate API key button to make an API key that can be used for access. This API key will be used in other steps of this guide.

Add organizations

Some organizations have to be added to use the current import process. Currently these have to be added manually. Add organizations with the names: EPOS Multi-scale Laboratories Thematic Core Service and yoda repository.

Import data

Set texts

Go to the Sysadmin settings section which is linked to in the top right menu. Click on the Config tab and set the following values using the form.
