Products

Structured Dynamics' growing product portfolio is geared to power the semantic enterprise. It leverages existing assets with interoperable technologies and linked data. Our products and applications enable users to discover, connect, communicate, and share knowledge in new and innovative ways. We share your vision to get information to interoperate, regardless of legacy or form.

Open Semantic Framework

SD's flagship product is the Open Semantic Framework. OSF is a complete and integrated software stack that combines external open source components with specific enhancements developed by Structured Dynamics (see features list). OSF is a complete foundation to bring semantic technology capabilities to the enterprise. OSF has a variety of potential applications from enterprise information integration to collaboration networks and open government.

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 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.

Modern IT architectures are evolving to become Web-based and layered. They are Web-based because the designs are proven, simple, scalable and accessible. They are layered to prevent "lock-in" to particular vendors or standards and to allow incorporation of new innovations, including open source.

The basic architecture of the Open Semantic Framework pivots around the OSF Web Services; there are now nearly 30 providing a wealth of functionality. Full CRUD under user permissions and security is provided to all digital objects in the stack. This OSF access layer provides a means to access best-of-breed data management and indexing engines through uniform RESTful Web services. These access services both: 1) abstract away the complexity of the individual engines, while 2) enabling combined capabilities orchestrated by OSF not available from the engines alone.

This intermediate OSF Web Services layer may also be accessed directly via API or command line or utilities like cURL, suitable for interfacing with standard content management systems (CMSs), or via a dedicated suite of connectors and modules that leverage the open source Drupal CMS. These connectors and modules, also part of the standard OSF stack and called OSF for Drupal, natively enable Drupal's existing 10,000 modules and ecosystem of developers and capabilities to access OSF using familiar Drupal methods.

This basic architecture from user interface to engines is quite simple in design:

Simple OSF Stack

In this design, OSF is the meat in the sandwich that links a proven content management system, Drupal, with proven semantic technology engines such as Virtuoso, GATE, OWL API 2, and Solr. What had heretofore been unconnected capabilities are now integrated via the OSF glue.

The premise of the entire stack is based on the RDF data model. RDF provides the ready means for integrating existing structured data assets in any format, with semi-structured data like XML and HTML, and unstructured documents or text. The OSF framework is made operational via ontologies that capture the domain or knowledge space, matched with internal ontologies that guide OSF operations and data display. This design approach is known as ODapps, for ontology-driven applications.

The OSF stack is supported by complete documentation, automated installation routines, comprehensive unit and end-to-end tests, and workflows and use case studies to ease adoption. SD is available to provide experienced support, training and development services.
