Here are some selected testimonials from clients on Structured Dynamics' recent services.

Healthdirect Australia

Healthdirect is a Council of Australian Governments initiative and as such is a dynamic, demanding and high profile health information provider subject to the highest government standards.

Structured Dynamics proved an excellent partner able to challenge preconceived ideas while establishing a fantastic grounding for semantic enablement of our content platforms using their deep knowledge and thought leadership in content management, semantic organisation and search. I have no hesitation in recommending their services.

-- Bruce Haefele, Chief Architect, Healthdirect Australia

United Way of Winnipeg

Many thanks. We had the privilege of showcasing a site and system that is really quite remarkable. What a pleasure. Please be assured that in every conversation, we brag about you guys.

I enjoyed hearing very positive feedback from many – including senior officials in the Winnipeg Regional Health Authority, Federal Government, University of Winnipeg, Royal Bank, Assinboine Credit Union, Chamber of Commerce . . . from a number of non profits . . . And from the head of Pathways (Toronto) and a woman who heads a Foundation in Vancouver.

-- Connie Walker, Vice President, United Way of Winnipeg

Volkswagen UK (Tribal DDB)

StructWSF provided a great solution to a complex problem that otherwise could have taken months, if not years to solve.

For a project that had great business expectations combined with huge uncertainty, it was one of the key ingredients to a successful delivery.

-- William Greenly, Volkswagen UK Technical Lead @ Tribal DDB

City of Winnipeg

I wanted to thank you for your dedication and hard work that you have put into the NPI. Clearly without your skills we would not have the great site that is shaping up. I have found working with you a real opportunity for learning – not only the technical work that you do, but also how you work so well with people.

I am also thrilled that we will be continuing on with Structured Dynamics for the next few months while we attempt to catch up with all the great work you have done in building the site.

-- Kelly Goldsmith, NPI Coordinator, City of Winnipeg

Other SD Resources

These are projects or initiatives that have been created or co-created by Structured Dynamics.

Sandboxes & Demos

UMBEL Web Services UMBEL Web Services
This site provides access to about a dozen UMBEL reference subject concept Web services in areas such as lookups, concept explorer, subject concept details, and SPARQL endpoints. The demo also provides API descriptions and access. See also the UMBEL ontology below.

Technologies & Open Source Software

Open Semantic Framework (OSF) Open Semantic Framework
The Open Semantic Framework is Structured Dynamics' flagship open source initiative, with many individual constituent projects. OSF is platform-independent software for accessing and exposing structured RDF data, with generic tools driven by underlying data structures. OSF may be placed over virtually any existing datastore with Web access.

OSF was a layered design built around a Web-oriented architecture, with these layers (from bottom up):
  • OSF engines layer — third-party, open-source tools for indexing and searching the RDF data and OWL ontologies
  • OSF Web Services layer — about 30 RESTful Web services that provide the abstract access point to manipulate all information in the system, including basic create, read, update and delete operations
  • The middleware layer — APIs and facilities for enabling connections with enterprise middleware such as security access and version control
  • The OSF for Drupal layer — the standard content management layer based on Drupal that provides the user interface and extension conventions for the framework, and
  • OSF management tools — a variety of command-line tools such as ontology management, data loading and conversion, system and integration testing, etc, useful for ongoing maintenance of an OSF instance.

Ontologies & Vocabularies

UMBEL Subject Concept Ontology UMBEL
UMBEL (Upper Mapping and Binding Exchange Layer) is a lightweight vocabulary of 35,000 subjects and the conceptual relationships between them. The UMBEL backbone is also a reference structure for more specific vocabularies for interrelating and connecting more specific domains, and can act as binding or attachment points for any Web content or data. It is based on SKOS and derived from the Cyc knowledge base.
irON irON
irON (the instance record and Object Notation) is a abstract notation and associated vocabulary for specifying RDF triples and schema in non-RDF forms. Its purpose is to allow users and tools in non-RDF formats to stage interoperable datasets with RDF using either JSON, XML or CSV formats.
Cycorp Bibliographic Ontology
The Bibliographic Ontology (BIBO) provides main concepts and properties for describing citations and bibliographic references (i.e., quotes, books, articles, etc) on the semantic Web. It can be used as a citation ontology, a document classification ontology, or a way to describe any kind of document in RDF.
Music Ontology Music Ontology
The Music Ontology is an attempt to link all the information about musical artists, albums and tracks together, from MusicBrainz to MySpace. The goal is to express all relations between musical information in order to help people find anything about music and musicians. It is based around the concept of machine readable information provided by any web site or web service on the Web.

Documentation & Methodologies

OSF Technical Knowledge Base OSF Technical Knowledge Base
OSF Technical Knowledge Base is the generic technical wiki providing documentation for the software and related systems associated with the various Open Semantic Framework open source software projects. Its nearly 400 technical articles, many figures, organization and infrastructure provide a complete, open source knowledge base that itself can be downloaded and modifed for local use (including branding and proprietary modifications). OSF Wiki documentation relates to all parts of the open semantic framework (OSF).
Open SEAS (Semantic Enterprise Adoption and Solutions) is an open source methodology, complete with documentation, compliant with MIKE2.0 (Method for an Integrated Knowledge Environment) for helping enterprises to transition into semantic technologies and applications.
