Component Name

Description

Registry Components and SI Services: Registry

Refer to the descriptions for each component in the following rows.

Box Name: Artifact Reference and Store

This registry component The artifact reference is a store or registry that contains references to the various artifacts.   Each artifact should have a URL that can be used to physically access the file.   Each artifact reference is accompanied by a checksum or some other method to be able to verify the accessed object.

Box Name: Artifact Access

This registry component provides programmatic access to artifacts in the Artifact Reference and Store.

Box Name: Artifact Registry and Retrieve

This registry SI service provides a programmatic method for accessing artifacts within the SIinterface for interacting with the artifact reference registry.

Box Name: Transformation Governance Integration

This registry SI service provides a service that has a number of services that take as input some artifact and outputs in alternative representations.  This might include a class model in UML being transformed to an OWL ontologystate mechanisms about known artifacts that can be accessed and reviewed through governance activities.

Box Name: Validation and Compliance Suite

This registry SI service integrates with the reasoning system to validate the compliance of specific artifacts (ECCF models).

Semantic Components and SI Services: Semantic

Refer to the descriptions for each component in the following rows.

Box Name: Semantic Knowledge Store

This store semantic component provides a physical representation of semantics that have either been derived through artifact analysis, or through manual annotation.   This store could be represented by an RDF (Resource Description Framework) triple store.

Box Name: Artifact Registry and Retrieve Transformation

This semantic component provides a function that takes as input some artifact and provides output in alternative representations. This might include a class model in UML being transformed to an OWL ontology The registry and retrieve service provides a programmatic interface for interacting with the artifact reference registry.

Box Name: Automated Semantics Discovery Suite

This semantic SI service takes an as input artifacts or artifact transformations and extracts as much semantics many semantic representations as possible.   The details and amounts of the semantics will depend on artifact type, representation, and completeness. The results are then stored in the Semantic Knowledge Store.

Box Name  Name: Annotation Semantic Reasoning Platform

This semantic SI service provides description logic based functionality that uses inferencing to allow additional semantics (assertions) The annotation services provides functionality which allows additional semantics to be added to about an artifact reference in the Semantic Knowledge store, supporting capabilities such as checking ontology consistency, building classification, verifying the satisfiability of concepts, and checking entailment.

Box Name: Orchestration

The orchestration service manages the internal flow of operations which can be performed.  This includes automating the transformation and semantic discovery and the utilization of various rule systems or classification systems.

Semantic Query

This semantic SI service provides querying functionality on the semantics of an artifact reference in the Semantic Knowledge store. Different querying mechanisms may be supported, including but not limited to graph-based, rule-based, tree or directory-based, and object-based.

Box Name: Annotation

This semantic SI service provides functionality that allows additional semantics to be added about an artifact reference in the Semantic Knowledge store, and is used to augment the semantic representations which were automatically discovered.

Box Name: Data Transformation Service

This semantic SI service provides a set of transformation functions which are designed to transform data; this may include transforming data graphs into CSV, result sets into XML, or other reasonable transformations. This function may use semantics stored about artifacts to aid in the transformation function.

SI Framework Components and SI Services: Framework

Refer to the descriptions for each component in the following rows

Box Name : Governance Integration

To support governance, this service provides state mechanisms about known artifacts that can be accessed and reviewed through governance activates.

Box Name: Access Service Directory

This directory represents framework component provides the set of services that are available within an SI a Semantic Infrastructure implementation which are designed to manage artifacts and their semantic representations.   This will allow for the coordination of stores and services across the grid.

Box Name: Reasoning Framework Service Directory

This framework component provides the set of services that are available within a Semantic Infrastructure implementation that provide reasoning functionality to analyze artifacts and instance representations of associated data.

Box Name: Rule Systems System Interface

This framework component provides The rule systems provide integrations of one or more rule systems that provide to support to the SI to express Semantic Infrastructure in expressing business rules and behaviors.

Box Name: Classification Reasoners Interface

This framework component provides integrations for Classification reasoners provide integration to one or more classification tools.   These tools are systems that process semantic and dependent information and dependant to determine relationships and associations of classes and individuals which may be expressed in an artifact,  its its annotated information, or  or instance representations of associated data.

Box Name:
Expert Systems System Interface

This framework component The expert systems interface provides integration to one or more expert systems.   These systems utilize a set of known facts and domain expert definitions to determine additional semantics and functional definitions within the artifact semantic information and instance representations of associated data.

Box Name: Reasoning SI Services Framework Service Directory

This framework component provides interface support to semantic and reasoning services This directory represents the set of services that are available within an SI implementation provide reasoning functionality to analyze artifacts and instance representations of associated data.

Box Name: caGrid 2.0

Is the connectivity and secure transmission hub for communications with institutions utilized by NCI and it’s associated cancer centers, research centers, and affiliated organizations.

Box Name : Grid Application Toolbox

This is a collection of tools and libraries which are designed to make integration to the caGrid easier and more efficient.

Box Name : caGrid Enabled Applications

Any application that utilizes the grid for communications.  These apps may utilize the Grid Application Toolbox or provide their own interface to the caGrid .  Examples of these applications include the caBig Clinical Information Suite and caTissue.  This will also include infrastructure tools such as Form definition tools, query tools and code generation systems.
