• Content Enhancement: services that add semantic information to “non-semantic” pieces of content.
• Reasoning: services that are able to retrieve additional semantic information about the content based on the semantic information retrieved via content enhancement.
• Knowledge Models: services that are used to define and manipulate the data models (e.g. ontologies) that are used to store the semantic information.
• Persistence: services that store (or cache) semantic information, i.e. enhanced content, entities, facts, and make it searchable.

Apache Stanbol was initiated by the European R&D project IKS - Interactive Knowledge Stack and is currently undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC.

The Stanbol integration is leveraging Drupal's native support for RDF annotation and provides the infrastructure for:

• named entity recognition and automated tagging based on open data or custom thesauri
• HTML5 Inline Editing using Aloha Editor
• content enrichment from internal or Linked Open Data sources (linked media)
• multilingual content enhancement (even Romanian in the future).
