# III. Overview of Metadata Management Page

Metadata management is divided into three parts: meta-event management, event attribute management, and user feature management.

Each part can be searched and set separately. After setting, meta-events, event attributes and user features will be displayed in each analysis model with new conditions and display names.

# IV. Usage of Metadata Management

# 4.1 Basic Requirements for Meta-events, Event Attributes, User Attributes

  1. A meta-event is a set of attributes that do not have a data type and can have the same name as an event attribute or a user attribute.
  2. The name of the event attribute is globally unique and the type is consistent, i.e. any modification to any attribute is a global modification.
  3. The name of the user feature is globally unique and the type is consistent, i.e. any modification to any attribute is a global modification.
  4. Event attributes and user features are two systems, i.e. event attributes and user attributes with the same name.
  5. Names of all preset attributes preceded by '#'.
  6. The default display state for all preset attributes follows its initial settings, and the default display state for all custom events or custom attributes is 'visible'.

# 4.2 Query and Edit Meta Events

Events can be retrieved by filtering specified condition, showing all events by default:

Click 'Modify' to modify the display name, display status and comments.

The display name will affect the display name in the analysis model, and the status will affect whether it is displayed in the analysis model:

You can query all event attributes under specific events and modify event attributes.

Since events or attribute modifications are global modifications, modifying attributes here will also affect the situation under the event attribute module:

# 4.4 Query and Edit Event Attributes

Like query editing of meta-events, event attributes can be retrieved by filtering specified conditions, and all event attributes are displayed by default. In addition, the event attributes can be queried with the option of 'preset or not'.

The modification of event attributes is a global modification:

# 4.5 Query and Edit User Features

The same as query editing for meta-events, user feature retrieval can be done by filtering specified conditions, showing all user features by default. In addition, user features have the option of 'preset or not' can also be queried.

Modifications to user features are global:
