Follow-up to the Webinar: TopBraid Suite Solution Case Study -Demo of the Netherlands Ministry of Justice Metadata Workbench
The following items are provided for download:
For recent publications on this solution (by the Ministry of Justice) see:
Solution Overview:The Netherlands Ministry of Justice (MoJ) Metadata Workbench is a new approach to the design of XML messages and generation of XML Schemas based on the UN/CEFACT Core Component Technical Specification (CCTS). This approach makes it possible to collaboratively design messages for data exchanges within and between organizations that are specific to the local context while remaining compliant with industry and enterprise standards.
The MoJ solution is a semantic, model-driven solution built on the TopBraid Suite platform. We will discuss how Semantic Web standards were key to the capabilities, flexibility and reuse provided by this data exchange solution. We will demonstrate the solution, explore the solution requirements and architecture and the use of the key capabilities of TopBraid Suite including SPARQLMotion and the TopBraid Live SDK.
The following description is extracted from the full article cited above.
Exchanging information between government parties requires a consistent, reusable and repeatable approach to specifying data exchanges as structured electronic business documents built from components. As a principal member of the Central Information Systems of the Dutch government, the MoJ is pioneering new approaches to business documents and message design with an emphasis on semantic checking, model-based generation of schemas and reuse of business components.
To bridge the conceptual world and the implementation-driven world of electronic messaging, an additional standard is needed to provide a foundation. The United Nations Centre for Trade Facilitation and Electronic Business (UN/CEFACT) “Core Component Technical Specification (CCTS)” standard was chosen. CCTS describes an electronic message in logical terms.
Using the CCTS Ontology Models, Information Analysts tailor and compose components to specify the business documents that make up the electronic messages. An Adobe Flex-based User Interface is used to construct the message exchange schemas. Ontologies are queried and updated using TopQuadrant’s TopBraid Live SDK.
Constructing a Business Document in the MoJ Metadata Workbench
From “Rich” Ontologies to “Precise” MessagesOntology models are “rich” in the sense that they capture precise semantics about subject areas of interest. Electronic messages are, by necessity, concise descriptions about situations and affairs. CCTS provided the standard to define business documents and OWL fulfilled the need for more expressive power than XML.
Within the MoJ, a program for an ontology-based approach was started in 2007, motivated by the failure of Object Models and XML Schemas to deliver a reusable component-based solution. These approaches lacked sufficient semantic consistency for transformation to message building blocks. OWL is used both for the representation of the conceptual models of legal domains, UN/CEFACT core components, and business documents (data exchange definitions).
Information Analysts use the model-driven Metadata Workbench to tailor and compose components to specify the business documents that make up the electronic messages. XML Schemas are then generated for use by the various MoJ organizations and systems. One of the deployed projects, the Criminal Law Chain, will be used for demonstrations, and to highlight insights and lessons learned. |
