The Open Semantic Framework (OSF) is an integrated software stack using semantic technologies for knowledge management. It has a layered architecture that combines existing open source software with additional open source components. OSF is designed as an integrated content platform accessible via the Web, which provides needed knowledge management capabilities to enterprises. OSF is made available under the Apache 2 license.

OSF has a variety of applications from enterprise information integration to collaboration networks and open government. The system provides:

  • Data integration across all content and data types
  • Knowledge management
  • Semantic search across the enterprise
  • Distributed, differential data access and permissions, and
  • Publishing and managing your information.

OSF can integrate and manage all types of content — unstructured documents, semi-structured files, spreadsheets, and structured databases — using a variety of best-of-breed data indexing and management engines. All external content is converted to the canonical RDF data model, enabling common tools and methods for tagging and managing all content. Ontologies provide the schema and common vocabularies for integrating across diverse datasets. These capabilities can be layered over existing information assets for unprecedented levels of integration and connectivity. All information within OSF may be powerfully searched and faceted, with results datasets available for export in a variety of formats and as linked data.

The OSF stack consists of multiple layers. In the standard configuration, there is tight integration with Drupal 7 and its leading modules, enabling use of OSF with standard Drupal interfaces and constructs. All interactions with OSF occur via a robust layer of nearly 30 Web services and their associated APIs, which abstract and simplify how to interact with the stack. The OSF engines layer provides RDF and OWL management capabilities using the proven Virtuoso (RDF), Solr (search), OWL API (ontologies) and GATE (tagging and NLP) standalone applications. Besides Drupal and these engines, all remaining OSF components and Web services have been developed specifically to achieve the complete architecture of the Open Semantic Framework. OSF has been developed over six years and is now in version 3.x.

OSF features an automatic installer, a variety of command-line tools useful for managing the OSF stack and its information, extensive unit and systems test suites, and comprehensive documentation and how-to guides.
