Components for Development

Box name:UML Transformation

The UML transformation process takes a standard UML representation (XMI) of a model and performs analysis to determine semantics and definitions.

Box name:XML Transformation

The XML transformation process takes XML Schemas and XML instances to generate and determine semantics and definitions.

Box name:RDF/OWL Librarian

The librarian is responsible for knowing what definitions are represented in the registry. In addition, the librarian is responsible for versioning and representation of the governance process.

Box name:Transformation/Extraction Cache Controller

The cache controller is used to improve performance and interactions of the various components. Since reasoning systems may require the merging of large amounts of knowledge, the controller will prevent unnecessary fetching operations.

Box name:DIFF Tool

The DIFF tool provides a number of functional behaviors such as determining differences between two versions of semantic representations. In addition, the diff tool looks at the semantics to determine if two systems of representations may have common areas of interest.

Box name:Reasoner Controller

Manages the reasoner configurations and implementations so when called upon they are properly configured.

Box name:Reasoner Orchestration Tool

The orchestration tool provides integration between reasoners. This allows for the staging of reasoning systems to allow for concurrent or parallel processing of reasoning systems..

Box name:Reasoner Session Manager

Since users may perform interaction with the reasoning systems with specific knowledge stores and reasoner configurations, the session manager maintains the state and processes until the user or system no longer requires it.

Box name:ECCF KM API

The set of functional APIs that can be called by applications.

Box name:ECCF KM Remote Service API

The set of remote service APIs that are called by applications. These set of service calls include appropriate implementations such as SOAP and RESTful services.

Box name:ECCF KM Web Interface

The Web interface is a web application that users can use to interact with the Knowledge Manager. From this application users can upload knowledge sources for processing by the reasoners, download semantic representations of processed models and schemas, as well as perform direct queries against the knowledge stores.

Data Stores

Box name:RDBMS Store

This is information stored in traditional RDBMS stores with traditional schemas. Semantic access to these system will be performed using the open source tools.

Box name:Triple Store

The most flexible representation of semantic information is stored in a triple store. There are multiple possible physical representations including files, RDBMS triple stores, and dedicated high performance triple stores.

Open source components

Box name:Jena

Jena is a standard interface tool that allows for the access of triple store information in RDF and OWL formats. Jena is a very flexible tool with the ability to interact with the stores with various reasoners.

Box name:ARQ (SPARQL)

ARQ is an implementation of the SPARQL language. SPARQL provides a standardized query language for interacting with triple stores.

Box name:Pellet

Pellet is an OWL 2 reasoner. Pellet provides standard and reasoning services for OWL ontologies.

Box name:FaCT ++

FaCT++ is an OWL DL reasoner (partially OWL 2), is implemented in C++ and uses optimized tableaux algorithms.

Box name\:D2RQ

A tool, which works with traditional RDBMS structures and presents them using RDF semantics. This allows for SPARQL queries of RDMS data, as well as integration with reasoning systems.

Box name:Other Reasoners

The jena tool provides for integrations with alternative reasonsers, which can be determined later.
