Some system records that store configuration information can be
modified by the user.
The next three topics describe how
you can configure the following system records, all of which are user-created
except for the GCR:
- Property Description
Record (PDR) for a standard attribute. PDRs are used to define the format
and behavior of standard attributes and managed attributes.
- Dimension Description
Record (DDR) for a managed attribute. DDRs are used to define managed
attributes and thus, among other characteristics, enable the creation of
hierarchical attribute values.
-
Global Configuration Record (GCR), used to control various
aspects of the global configuration. The GCR is automatically created when the
data domain is created, but it can be changed afterwards by the user.
In addition, other configurable system record types exist. They are also
described in this guide:
- Managed Attribute Value
Description Records (MAVDR) for a user-created managed attribute value. For
operations to create managed attribute values, see
Operations for Managed Attribute Values.
- Collection Description
Record (CDR) for a collection. For the operations to create and modify
collections, see
Collection operations.
- Filter Rule Description
Record (FRDR) for a filter rule. For the operations to create and modify
filter rules, see
Filter rule operations.
- Precedence Rule
Description Record (PRDR) for a precedence rule. For the operations to
create and modify precedence rules, see
Using Precedence Rules.
- Entity Description Record
(EDR) for an entity. For the operations to create and modify filter rules,
see
Working with Entities.
- Group Description Record
(GDR) for the configuration of an attribute group. For the
updateGroupConfigs operation to update the config, see
Updating the group configuration.
- Group Membership
Description Record (GMDR) for the membership of an attribute group. For the
operations to create and modify the attribute group membership rules, see
Using Attribute Groups.
To avoid naming collisions with customer-created records and attributes,
the keys for system records use reserved prefixes, such as
mdex-property.
