Introduction
This document contains definitions of terms and acronyms found in the documentation for the
Metasys system products and serves as a convenient reference.

A
Active Directory Federated Systems (ADFS)
Active Directory Federated Systems. ADFS is an add-on, licensed feature to add support for
Metasys using Active Directory Federation Services (ADFS), a single sign-on solution developed
by Microsoft®. ADFS can then, in turn, be used to provide 2-factor authentication for access to
Metasys.
Active Directory Service
A network operating technology that enables Information Technology (IT) administrators to
manage enterprise-wide information from a central repository. This information includes data
center policy compliance and identity management (user logon accounts), which are used for both
Microsoft® Windows® Operating System (OS) authentication (logon to the Windows OS) as well as
network resource authentication (logon to enterprise-wide secured applications, such as email).
Active Directory Service Domain/Domain Controller
A collection of domain controllers that serve as a security boundary for network resources.
A domain controller provides the Active Directory service to network users and computers;
stores directory data; and manages user and domain interactions including the logon process,
authentication, and directory searches.
Active Directory Service Schema
The formal definition of all object and attribute data that can be stored in the directory. For
example, user is an object type with attribute data of name, first name, last name, e-mail, and so
on. The schema is made up of object classes and attributes. The base (or default) schema contains
a rich set of object classes and attributes to meet the needs of most organizations, and is modeled
after the International Standards Organization (ISO) X.500 standard for directory services.
Active Directory Service—Service Account
A logon account assigned to an application to enable the application to perform privileged actions
within Active Directory service. The Metasys system requires one or more Service Accounts to be
assigned to allow the system to perform directory queries and request Active Directory service
authentication. Only one Service Account is allowed per domain.
Active Directory Service User Account
A logon account assigned to a user account that is created, stored, and maintained only within
Active Directory service. This user account provides access to Active Directory service Network
Resources. The account may also provide access to the Metasys system when added and privileged
using the Metasys Security Administration system.
Application and Data Server, (ADS)
Application and Data Server, (ADS). A Metasys server that allows you to expand beyond the site
management capabilities, number of connections limitations, and historical data storage limits of
Network Automation Engines (NAEs), Network Integration Engines (NIEs), Network Control Engines
(NCEs), SNE series network engines, and SNC series network engines. An ADS uses a free version
of Microsoft® SQL Server® software to manage historical data on a computer that does not have a
server-class OS. For a more robust system, an extended ADS is available (ADX).

Application and Data Server, Lite version, (ADS-Lite)
Application and Data Server, Lite version. A lower-capacity Metasys server that is available for
purchase in Europe, Latin America, and Asia. The ADS-Lite products offer the same functionality as
the standard ADS, but can serve as the Site Director for only the smaller-capacity network engines
(NCE25/NIE29, NAE35/NIE39, NAE45/NIE49, and SNE110L0).
Advanced Graphics Application (AGA)
An enhanced graphics programming package that provides dynamic capabilities such as animation,
color changes, and flashing for the Metasys system. Dynamic graphics can be defined in Microsoft
Visio® Professional 2003 software using the Advanced Graphics add-on application and Graphics
Example stencil. Graphic files are converted to Scalable Vector Graphics (SVG) and imported into
the User Graphics Tool. You can access a second graphics viewer, the Adobe® SVG Viewer, from
within the existing user interface to view the advanced graphics.
      Note: AGA is no longer supported at Metasys Release 11.0.
Advanced Graphics Symbol Library (AGSL)
A collection of predefined dynamic graphics that can be defined in Microsoft Visio Professional 2003
software using the Advanced Graphics application and converted to Scalable Vector Graphics (SVG).
SVG files then can be imported into the User Graphics Tool and viewed in the Site Management
Portal User Interface (UI).
ADX
Extended Application and Data Server. A Metasys server that allows you to expand beyond the site
management capabilities, number of connections limitations, and historical data storage limits
of NAEs, NIEs, and ADSs. An ADX uses a full version of Microsoft SQL Server software to manage
historical data on a computer with a server-class OS.
Alarm Manager
A feature in the Metasys UI that provides a view of all alarms in the Metasys system. From this view,
you can take certain actions, such as sorting, acknowledging, and discarding alarms.
Application Programming Interface (API)
Metasys Monitoring and Commanding Application Programming Interface (API). This API enables
reading, writing, and commanding of one or more Metasys objects or properties to provide a
secure way to bi-directionally integrate with third-party applications. At Release 11.0, this API is
enhanced to optimize its integration with Johnson Controls Enterprise Management (JEM). This
ensures a robust and cyber-secure integration between Metasys and JEM.
Archive
