Atramhasis v0.5.0 released

A new version (0.5.0) of :pypi:`Atramhasis <atramhasis>` has been released. Atramhasis is an open-source, web-based SKOS editor. You can use it to browse SKOS vocabularies, thesauri, authority files, word lists, … Atramhasis also comes with an admin interface you can use to add the concepts and collections of your vocabularies.

This release is a major update based on the :pypi:`Skosprovider <skosprovider>` 0.6.0 line of libraries. The most visible change is with the public and admin interfaces. These have been completely overhauled to provide a more pleasing userexperience. Among other things visitors are now pointed towards popular concepts and concepts they have recently visited. Browsing an entire conceptscheme tree has been redesigned.

The admin interface now offers users an option to edit certain aspects of a conceptscheme such as the labels, notes and sources. Editing in general has been update and improved. Links between the public interface and the admin interface have been added to make switching from one to the other easier. Notes and sources can now contain certain HTML tags, allowing greater flexibility in defining concepts and collections.

A command line script was added to make it easy to import an entire conceptscheme, eg. when migrating from another system. It is now possible to import a RDF, CSV or JSON file on the command line in your Atramhasis instance. With earlier versions you had to script this yourself.

As always, bugs have been fixed, code has been rewritten and documenation has been updated. See for the full list of changes.
