Exporting Entities using OSF for Drupal (Screencast)

This screencast will introduce you to the OSF for Drupal features that let you export Drupal Entities in one of the following supported serializations:

  • RDF+XML (RDF in XML)
  • RDF+N3 (RDF in N3)
  • structJSON (Internal OSF RDF serialization in JSON)
  • structXML (Internal OSF RDF serialization in XML)
  • ironJSON (irON serialization in JSON)
  • commON (CSV serialization to be used in spreadsheet applications)

I will show you how you can use OSF for Drupal to export entire datasets of Entities, or how to export Entities individually. You will see how you can configure Drupal such that different users roles get access to these functionalities.

I will also briefly discuss how you can create new converters to support more data formats.

Finally, I will show you how Drupal can be used as a linked data platform with a feature that makes every Drupal Entities dereferencable on the Web1. You will see how you can use cURL to export the Entities‘ descriptions using their URI in one of the 6 supported serialization formats.

Configuring and Using OSF Ontology (Screencast)

This screencast will quickly introduce you to ontologies, and will explain you what are their rules in the Open Semantic Framework (OSF).
