CDR: Reference Architecture

Overview

This IC/DoD enterprise Content Discovery and Retrieval Reference Architecture (CDR RA) provide conceptual and contextual guidance to architects, engineers, and developers tasked to implement CDR specifications. The CDR Reference Architecture (RA) is the keystone artifact for the overall set of guidance artifacts. The primary content of the CDR RA is the definition of an extensible set of capabilities and components that are realized via service specifications. It also describes various architecture interaction patterns and the specific technical framework to enable robust, scalable, and repeatable implementations across varying business and mission boundaries.

The CDR RA defines two primary capabilities - content discovery and content retrieval and is comprised of six core CDR components: Search, Brokered Search, Retrieve, Describe, Deliver, and Query Management that provide these capabilities. The CDR RA describes an architecturally driven approach for guiding the IC/DoD Enterprise towards enabling content discovery and retrieval.

This specification supports Intelligence Community Directive 501(ICD 501), Discovery, Dissemination or Retrieval of Information within the Intelligence Community, which establishes policies for (1) discovery, and (2) dissemination or retrieval of intelligence and intelligence-related information collected, or analysis produced by the Intelligence Community.

This reference architecture is maintained by the IC Chief Information Officer via the Services Coordination Activity (SCA) and Content Discovery and Retrieval Integrated Product Team (CDR IPT).

Value Proposition

This CDR reference architecture defines two distinct, but inter-related capabilities: Content Discovery, and Retrieval.

  • Content Discovery provides consumers with the ability to discover the existence of potentially relevant content resources and content collections from across the IC/DoD Enterprise. Content Discovery also enables consumers to discover valuable metadata about content resources to support making them visible, accessible, understandable, and trusted.

  • Retrieval provides consumers the ability to retrieve and route specific content resources. To do so, content providers are to ensure their content is accessible to the Enterprise.

CDR: Search

Overview

This IC/DoD enterprise encoding specification defines requirements and provides guidelines for the realization of the Content Discovery and Retrieval (CDR) Search component as both a RESTful, OpenSearch [OS] web service and using the SOAP binding, hereafter termed a Search Service. This component provides a common interface and behavioral model for IC and DoD content collections, enabling content consumers to discover relevant content resources from disparate collections across the IC/DoD Enterprise. The content of this specification describes the Search Service’s behavior, interface and other aspects in detail, providing enough information for Search Service providers and consumers to create and use CDR-conformant Search services.

The Search service exposes a single Search operation that is responsible for three activities that underpin Content Discovery capabilities: search, result presentation, and results paging. A Search service’s results are resource metadata rather than actual content resources. In the context of Search, resource metadata generally refers to a subset of a resource’s available metadata, not the entire underlying record. Results normally contain information needed for a consumer to retrieve or otherwise use the referenced resource.


Value Proposition

This specification supports Intelligence Community Directive 501(ICD 501), Discovery, Dissemination or Retrieval of Information within the Intelligence Community, which establishes policies for (1) discovery, and (2) dissemination or retrieval of intelligence and intelligence-related information collected, or analysis produced by the Intelligence Community.

Compliance with this specification is measured against all aspects of the technical and documentary artifacts contained within the specification release package. This specification is maintained by the IC Chief Information Officer via the Services Coordination Activity (SCA) and Content Discovery and Retrieval Integrated Product Team (CDR IPT).

This specification is designed to fulfill a number of requirements in support of the transformational efforts of the Intelligence Community and Department of Defense Enterprise(IC/DoD). Features of this specification are to:
  • Searching through content and metadata in multiple formats as specified by the consumer, such as image files and textual documents.
  • Searching through information content that is static, dynamic, structured and unstructured.
  • Enable searching through and appropriately processing of information content and metadata at different classification levels, and with different handling caveats; information which could be located on different security domains.
  • Searching through natural language content (probably in many different languages) or highly formatted content such as geospatial or temporal content. (Data sources can be active [current, dynamically changing] or historic [static], each containing different data types).

CDR: Query Management

Overview

This IC/DoD enterprise encoding specification defines requirements and provides guidelines for the realization of the Content Discovery and Retrieval (CDR) Query Management component as a web service using both a RESTful, OpenSearch [OS] and SOAP style binding, hereafter termed the Query Management (QM) Service, as a web service using the SOAP style binding. The Query Management (QM) Component, as defined by the “IC/DoD Content Discovery and Retrieval (CDR) Specification Framework” , is a CDR Component that manages Saved Searches and may initiate search requests based on Saved Searches. It describes the external service interfaces and the internal activities that provide service behaviors so that service providers and consumers can create and use CDR-compliant Query Management Services.

This specification supports Intelligence Community Directive 501(ICD 501), Discovery, Dissemination or Retrieval of Information within the Intelligence Community, which establishes policies for (1) discovery, and (2) dissemination or retrieval of intelligence and intelligence-related information collected, or analysis produced by the Intelligence Community.

Compliance with this specification is measured against all aspects of the technical and documentary artifacts contained within the specification release package. This specification is maintained by the IC Chief Information Officer via the Services Coordination Activity (SCA) and Content Discovery and Retrieval Integrated Product Team (CDR IPT).


Value Proposition

This specification is designed to fulfill a number of requirements in support of the transformational efforts of the Intelligence Community and Department of Defense Enterprise(IC/DoD). ). The six functions listed below provide QM service consumers with a coordinated set of capabilities that support managing and using both searches and search related information. This specification mandates the generic interfaces that a QM consumer would utilize to manage and use a Saved Search:
  • Create –The Create function is used to insert a new Saved Search into the QM Collection.
  • Read – The Read function is used to retrieve a Saved Search from the QM Collection.
  • Update – The Update function is used to change a Saved Search in the QM Collection.
  • Delete – The Delete function is used to logically remove a Saved Search from the QM Collection.
  • Execute – The Execute function enables a QM consumer to execute (run) a Saved Search at the location specified by the Target Search Capability. To process an execute request, the Query Management Service retrieves the Target Search Capability (the location of the Search Service) and the Search Request from the Saved Search. This information is then used to initiate the Search. This capability SHOULD leverage the CDR Search approach to effect the execution of a Saved Search.
  • Search – The Search function enables a prospective consumer to interrogate the QM Collection on the basis of anything to be found in the Saved Search Bundle or the Saved Search Description to determine if a suitable search has already been created. Generic search terms can be used to provide functionality that provides a ‘list’ of the contents of the QM Collection. This capability SHOULD leverage the CDR Search discovery approach.

CDR: Deliver

Overview

This IC/DoD enterprise encoding specification defines requirements and provides guidelines for the realization of the Content Discovery and Retrieval (CDR) Deliver Component as a web service using both the SOAP messaging protocol and REST style binding, hereafter termed a Deliver service. This component provides a common interface and behavioral model for IC and DoD content collections, enabling content consumers to deliver relevant content resources from disparate collections across the IC/DoD Enterprise. The content of this specification describes a Deliver service’s interface and other aspects in detail, providing enough information for Deliver service providers and implementers to create CDR-compliant Deliver services.

The REST Deliver Service, as defined by the Intelligence Community/Department of Defense (IC/DoD) CDR Specification Framework, serves as a “push” mechanism to send information resources. The Deliver Service relies on mechanisms that are already well established in the internet infrastructure:
The SOAP Deliver Service exposes a Deliver function. While the function is often used in concert with delivering the results of a Content Discovery search, it may be used in general to process any compliant Deliver instructions. The Deliver function can be used in a few different patterns:
  • Deliver content provided by the entity invoking the service to a default or specified recipient(s)
  • Deliver content obtained as the result of a previous query to default or specified recipient(s)
  • Deliver based upon additionally specified criteria (e.g. time, event)
The Deliver Service facilitates the transfer of a content resource to a specified destination. In its simplest form, the Deliver Service will take a consumer-supplied payload and send it to another consumer as specified by the delivery destination and properties. The Deliver Service may include additional (interim) processing, including but not limited to compression, encryption, or conversion.

This specification supports Intelligence Community Directive 501(ICD 501), Discovery, Dissemination or Retrieval of Information within the Intelligence Community, which establishes policies for (1) discovery, and (2) dissemination or retrieval of intelligence and intelligence-related information collected, or analysis produced by the Intelligence Community.

Compliance with this specification is measured against all aspects of the technical and documentary artifacts contained within the specification release package. This specification is maintained by the IC Chief Information Officer via the Services Coordination Activity (SCA) and Content Discovery and Retrieval Integrated Product Team (CDR IPT).


Value Proposition

This specification is designed to fulfill a number of requirements in support of the transformational efforts of the Intelligence Community and Department of Defense Enterprise(IC/DoD). Features of this specification are to:
  • Enable a content resource to be delivered to a specified location which may or may not be the requesting component.
  • Provide additional processing of the content to make it suitable for delivery to its destination and delivery path to be used.
  • On behalf of the consumer, retrieve the requested content and then deliver to the specified location.
