IDOL 23.2

IDOL Core Components

This section describes the common IDOL components.

The following components form the core IDOL text indexing and processing functions. Together, they are often collectively known as IDOL Server. For more information, refer to the IDOL Server Help.

IDOL Text Processing
Service	Description
Content	Indexes, collects, manipulates and stores unstructured and semi-structured text data.
AgentStore	Indexes, collects, manipulates and stores agent and category information. Agentstore is a special configuration of the Content component.
Category	Stores predefined or customized categories in which data is organized.
Community	Stores information about users, roles, and permissions.
View	Converts documents to HTML format for viewing in a Web browser.

The following components form part of a wider IDOL infrastructure. They allow you to license, distribute, monitor, and control your IDOL components.

Infrastructure
Service	Description
License Server	Distributes and manages licenses for IDOL products and components. Refer to the License Server Help for more information.
IDOL Proxy	Routes actions to the correct components in a unified IDOL Server, and starts, restarts and stops IDOL components.
DAH	Distributed Action Handler. Distributes action requests across IDOL Servers or IDOL components. Refer to the DAH Help for more information.
DIH	Distributed Index Handler. Distributes indexing requests across IDOL Servers or IDOL Content components. Refer to the DIH Help for more information.
Controller	Monitors the IDOL services on a host machine, and communicates with Coordinator to report status information. This component is primarily used by IDOL Site Admin. Refer to the IDOL Site Admin User Guide for more information.
Coordinator	Manages status information from Controllers, and acts as a central point for viewing logs and monitoring the status of the IDOL system. This component is primarily used by IDOL Site Admin. Refer to the IDOL Site Admin User Guide for more information.

The following components allow you to automatically retrieve content and index into IDOL.

Connectors
Service	Description
CFS	Connector Framework Server. Aggregates data from IDOL connectors and indexes the data into IDOL Server. CFS can also manipulate the index content (for example, to additional fields relevant to the content), and index into other systems, such as Knowledge Graph and Vertica databases. Refer to the Connector Framework Server Help for more information.
NiFi Ingest	IDOL NiFi Ingest is an alternative to CFS. It uses Apache NiFi to allow you to easily configure and manipulate your data ingest process, from your connectors, to KeyView and other import processes (such as media analysis and Eduction), and your IDOL index. Refer to the NiFi Ingest Help for more information.
Connectors	Gather data from different sources for indexing into IDOL. The IDOL Server installer includes the File System Connector and the Web Connector. The File System Connector gathers data from system files, while the Web Connector gathers data from Web servers (internet or intranet). Refer to the Connector Administration guides for more details.

The following components perform additional operations and analysis on unstructured data. You can use many of these components with the IDOL text processing, or as part of an independent system.

Additional Services
Service	Description
Answer Server	Performs natural-language question answering, and conversations. Answer Server can answer questions from a database of facts, from a stored list of questions such as an FAQ, or by returning a relevant passage from a relevant store of unstructured data. It can also manage ongoing conversations with context, for example to run a chatbot.
QMS	Query Manipulation Server. Manages promotions, modifies queries to IDOL Server, and manipulates results from IDOL Server. Refer to the Query Manipulation Server Help for more information.
Statistics Server	Accumulates events from client applications or from a script that reads IDOL log files, then uses that data to report statistics. Refer to the Query Manipulation Server Help for more information.
Media Server	Analyzes video files and streams, images, and audio to extract information about their content. Media Server can run analysis operations such as face recognition, number plate recognition, speech-to-text, and speaker identification. Refer to the Media Server Help for more information.
Knowledge Graph	Uses connections between IDOL documents to create a set of relationships called a graph, and allows you to explore these connections in your data. Refer to the Knowledge Graph Technical Note for more information.
OGS	OmniGroupServer. Collects security information from security repositories and uses it to ensure that users can access only documents that they have permission to access. Refer to the IDOL Document Security Administration Guide and OmniGroupServer Reference for more information.
