ckanext-dcor-schemas 0.9.0

Introduces or lifts restrictions (authorization) for managing data and metadata on DCOR

This module introduces/lifts restrictions (authorization) for the management of data and meta data on DCOR. The corresponding UI elements are modified accordingly:

• Authorization (auth.py)

  • allow all logged-in users to create datasets, labs, and collections

  • do not allow deleting datasets or resources unless they are drafts

  • allow purging of deleted datasets

  • do not allow adding resources to active datasets

  • do not allow bulk_update_delete (e.g. datasets by organization admins)

  • dataset: do not allow switching to a more restrictive license

  • dataset: do not allow changing the name (slug)

  • resource: only allow changing the “description”

  • Do not allow uploading resources with the same name (ckanext-dcor_depot)

  • Allow adding resources up to 3h after creating dataset

  • Do not allow setting a resource id when uploading

• Permissions (plugin.py)

  • Allow a user A to see user B’s private dataset if the private dataset is in a group that user A is a member of.

• Validation (validate.py)

  • Do not allow setting a different resource name when uploading

  • Do not allow weird characters in resource names

  • Restrict to basic CC licenses

  • Author list “authors” is CSV

  • Parse DOI field (remove URL part)

  • Automatically generate dataset name (slug) using random characters if necessary (does not apply to admins)

  • restrict upload data extensions to .rtdc, .csv, .tsv, .pdf, .txt, .png, .jpg, .tif, .py, .ipynb

  • Force user to select a license

  • Do not allow non-admins to set the visibility of a public dataset to private

  • Configuration metadata (using dclab.dfn.config_funcs)

  • A dataset is considered to be a draft when it does not contain resources (validate.state)

  • Allow to delete draft datasets

• UI Dataset:

  • hide “add new resource” button in templates/package/resources.html

  • remove url, version, author, author_email, maintainer, maintainer_email (templates/package/snippets/package_metadata_fields.html)

  • add field authors (csv list)

  • add field doi (validator parses URLs)

  • add field references (parses arxiv, bioRxiv, DOI, links)

  • add CC license file licenses.json (only show less restrictive licenses when editing the dataset)

  • hide name (slug) editing form

  • dataset visibility is public by default

• UI Organization:

  • remove “Delete” button in bulk view

• UI Resource:

  • Resource: remove “URL” button when creating a resource (only upload makes sense) (fanstatic/dcor_schemas_data_upload.js and templates/package/snippets/resource_form.html)

  • Add metadata key sha256 (and protect it with IResourceController.before_update)

  • Do not show variables these variables (because they are redundant): [‘last modified’, ‘revision id’, ‘url type’, ‘state’, ‘on same domain’] (templates/package/resource_read.html)

  • Show DC config data via “toggle-more”

• Background jobs:

  • set the mimetype for each dataset

  • populate “dc:sec:key” metadata for each DC dataset

  • generates sha256 hash upon resource creation

Installation

Simply run

pip install ckanext-dcor_schemas

In the configuration file ckan.ini:

ckan.plugins = [...] dcor_schemas
ckan.extra_resource_fields = sha256
