Glossary

Here's A short list of vocabulary terms used throughout the ThingWorx documentation.

A

Term Definition
alert A declarative way to create an event in ThingWorx that is triggered when a defined value or limit is reached or exceeded. All properties in a Thing shape, Thing template, or Thing can have one or more alert conditions defined. Alert types are specific to the data type of the property; the following base types can be used for alerts: Boolean, Datetime, Infotable, Integer, Location, Number, and String.
alert history A comprehensive table that records all information when an alert is triggered. The data is stored until it is removed manually.
alert processing subsystem Subsystem that manages the alert history stream. See Subsystem.
alert summary Compiles data from the last reset of the server to the current state. You can view, acknowledge, and sort (by acknowledged or unacknowledged) alerts on the Alert Summary page.
AlwaysOn Proprietary binary protocol for communication between edge devices and the ThingWorx Platform.
application key Security tokens used for authentication in ThingWorx when not using a standard credentials method of authentication. They are associated with a given user and have all of the permissions granted to the user with which they are associated. Application Keys are typically used to assign permission control to remotely-connected edge-devices. Application keys are also known as: appKeys.
application log A collection of all of the messages that the ThingWorx application generates while operating. Based on your settings (such as WARN and DEBUG), this log can display system messages.
authenticator An entity that allows you to implement user authentication, such as single sign-on or certificates, outside of ThingWorx.

run time data Data represented by streams, value streams, data tables, blogs, wikis, and properties.

S

Term Definition
script log Contains all of the messages that the ThingWorx application generates while executing JavaScript services. You can use the logger.warn function to write information to the script log from the services you are running. Generally, ThingWorx will only publish errors to this log that are incurred while running a service.
security Granular security model available within the ThingWorx Platform. There are two sets of permissions, one for design time and one for run time. The design time permissions are for managing who is allowed to modify the model (create, read, update, and delete entities), while the run time permissions determine who can access data, execute services, and trigger events on a Thing (which includes Data Tables, Streams, and Users). For each permission, you can explicitly permit a User or Group to be able to do something (like edit a Thing) or explicitly deny a Group the ability to do something (e.g. the Users Group is not allowed to edit a Thing). You can apply permissions at the Group level and at the User level. An explicit denial of a privilege always overrides a privilege grant.
SecurityClaim A class common to all of the object-oriented Edge SDKs used by a ClientConfigurator to store authentication information for a ConnectedThingClient.
security log Contains all of the messages that the ThingWorx application generates regarding users. Depending on the log level, it can include login and page requests information.
service A function which a Thing can perform. A service can be defined at the Thing Shape, Thing Template, or Thing level.
SQUEAL Search, query, and analysis capability within a model. SQUEAL can be accessed from any model at /Thingworx/Squeal.
state definition A collection of style definitions that are applied using data-based rules in a mashup. Evaluating the data to specific ranges or values allows you to perform data-based formatting, such as changing the background color of cells in a grid widget.
stream A storage table that is optimized for time-series data. Writes to a stream are done asynchronously. Querying a Stream returns the entire record.
style definition A collection of HTML styling elements that can be applied to a widget. All colors, text, and line formats are managed and rendered in the mashup environment using style definition entities.
subscription An action that executes when an event occurs.
subsystem Configurable ThingWorx Platform functionality that can be adjusted for specific Platform performance requirements. See Subsystem.
system user A default user in ThingWorx that manages internal service permissions but allows external API layer permissions to be set for each user.

T

Term Definition

Thing The digital representation of physical assets and/or processes that have properties and business logic. All ThingWorx Things are based on Thing Templates.
Thing Shape An abstract definition that represents the behavior of a concrete Thing or Things. Defines properties, services, events, and subscriptions for Things that implement the Thing shape. Typically, the Thing Shape is implemented by a Thing Template, which is then the basis of actual Things.
Thing Template Provides base functionality with properties, services, events, and subscriptions that Thing instances use in their execution. ThingWorx Things are derived from Thing Templates.
ThingWorx SDK Software development kit available in several languages, including C, Java, .NET, and iOS. The terms edge application or client application may be used when referring to a custom application built on an SDK. The term edge component may be used to describe a solution that includes multiple edge components (EMS, SDKs, ADO service, OPC service, etc.)
tunnel subsystem Subsystem that handles tunneling between remote Things. See Subsystem.

U

Term Definition

user group A collection of users to provide a common level of security-access. Allows you to categorize users of the ThingWorx system. User groups can contain users and groups. All permission settings and overrides are cumulative. The ThingWorx default security policy is restrictive. When you create a new group or user, the account will not have any rights in ThingWorx until you assign them.
user management subsystem Subsystem that manages session and password hash settings. See Subsystem.

V

Term Definition
value stream processing subsystem Subsystem that manages value stream storage and retrieval. See Subsystem.
value stream A storage table for time-series information about a Thing's property values. Querying a Value Stream returns the value of the specified property.
virtual Thing A modeled Thing defined in Edge that is represented as a remote Thing in the ThingWorx Platform.
visibility A simple form of access control. If an entity is visible to members of an organizational unit, those members have access to the entity, and the underlying granular security model determines what interaction members of that organization unit have with a specific asset. Visibility can be set at the collection level, the individual entity level, or at the visibility level of the Thing Template instance.
vocabulary A collection of terms used to create tags.
