Managed objects

A managed object is an object that represents the identity-related data managed by IDM. Managed objects are stored in the IDM repository. All managed objects are JSON-based data structures.

Managed object schema

IDM provides a default schema for typical managed object types, such as users and roles, but does not control the structure of objects that you store in the repository. You can modify or extend the schema for the default object types, and you can set up a new managed object type for any item that can be collected in a data set.

The _rev property of a managed object is reserved for internal use, and is not explicitly part of its schema. This property specifies the revision of the object in the repository. This is the same value that is exposed as the object’s ETag through the REST API. The content of this attribute is not defined. No consumer should make any assumptions of its content beyond equivalence comparison. This attribute may be provided by the underlying data store.

Schema validation is performed by the policy service and can be configured according to the requirements of your deployment.

Properties can be defined to be strictly derived from other properties within the object. This allows computed and composite values to be created in the object. Such properties are named virtual properties. The value of a virtual property is computed only when that property is retrieved.

Data consistency

Single-object operations are consistent within the scope of the operation performed, limited by the capabilities of the underlying data store. Bulk operations have no consistency guarantees. IDM does not expose any transactional semantics in the managed object access API.

For information on conditional header access through the REST API, see Conditional Operations.

Managed object triggers

Triggers are user-definable functions that validate or modify object or property state.

State triggers

Managed objects are resource-oriented. A set of triggers is defined to intercept the supported request methods on managed objects. Such triggers are intended to perform authorization, redact, or modify objects before the action is performed. The object being operated on is in scope for each trigger, meaning that the object is retrieved by the data store before the trigger is fired.

If retrieval of the object fails, the failure occurs before any trigger is called. Triggers are executed before any optimistic concurrency mechanisms are invoked. The reason for this is to prevent a potential attacker from getting information about an object (including its presence in the data store) before authorization is applied.

onCreate: Called upon a request to create a new object. Throwing an exception causes the create to fail.
postCreate: Called after the creation of a new object is complete.
onRead: Called upon a request to retrieve a whole object or portion of an object. Throwing an exception causes the object to not be included in the result. This method is also called when lists of objects are retrieved via requests to its container object; in this case, only the requested properties are included in the object. Allows for uniform access control for retrieval of objects, regardless of the method in which they were requested.
onUpdate: Called upon a request to store an object. The oldObject and newObject variables are in-scope for the trigger. The oldObject represents a complete object, as retrieved from the data store. The trigger can elect to change newObject properties. If, as a result of the trigger, the values of the oldObject and newObject are identical (that is, update is reverted), the update ends prematurely, but successfully. Throwing an exception causes the update to fail.
postUpdate: Called after an update request is complete.
onDelete: Called upon a request to delete an object. Throwing an exception causes the deletion to fail.
postDelete: Called after an object is deleted.
onSync: Called when a managed object is changed, and the change triggers an implicit synchronization operation. The implicit synchronization operation is triggered by calling the sync service, which attempts to go through all the configured managed-system mappings. The sync service returns either a response or an error. For both the response and the error, the script that is referenced by the onSync hook is called.

You can use this hook to inject business logic when the sync service either fails or succeeds to synchronize all applicable mappings. For an example of how the onSync hook is used to revert partial successful synchronization operations, see Synchronization Failure Compensation.

Object storage triggers

An object-scoped trigger applies to an entire object. Unless otherwise specified, the object itself is in scope for the trigger.

onValidate: Validates an object prior to its storage in the data store. If an exception is thrown, the validation fails and the object is not stored.
onStore: Called just prior to when an object is stored in the data store. Typically used to transform an object just prior to its storage (for example, encryption).

Property storage triggers

A property-scoped trigger applies to a specific property within an object. Only the property itself is in scope for the trigger. No other properties in the object should be accessed during execution of the trigger. Unless otherwise specified, the order of execution of property-scoped triggers is intentionally left undefined.

onValidate: Validates a given property value after its retrieval from and prior to its storage in the data store. If an exception is thrown, the validation fails and the property is not stored.

onRetrieve: Called on all requests that return a single object: read, create, update, patch, and delete.

onRetrieve is called on queries only if executeOnRetrieve is set to true in the query request parameters. If executeOnRetrieve is not passed, or if it is false, the query returns previously persisted values of the requested fields. This behavior avoids performance problems when executing the script on all results of a query.
onStore: Called before an object is stored in the data store. Typically used to transform a given property before its object is stored.

Storage trigger sequences

Triggers are executed in the following order:

Object Retrieval Sequence

Retrieve the raw object from the data store
The executeOnRetrieve boolean is used to check whether property values should be recalculated. The sequence continues if the boolean is set to true.
Call object onRetrieve trigger
Per-property within the object, call property onRetrieve trigger

Object Storage Sequence

Per-property within the object:
- Call property onValidate trigger
- Call object onValidate trigger
Per-property trigger within the object:
- Call property onStore trigger
- Call object onStore trigger
- Store the object with any resulting changes to the data store

Managed object encryption

Sensitive object properties can be encrypted prior to storage, typically through the property onStore trigger. The trigger has access to configuration data, which can include arbitrary attributes that you define, such as a symmetric encryption key. Such attributes can be decrypted during retrieval from the data store through the property onRetrieve trigger.

Managed object configuration

Configuration of managed objects is provided through an array of managed object configuration objects.

{
  "objects": [ managed-object-config object, ... ]
}

objects: array of managed-object-config objects, required

description

string, optional

A brief description of the property.

encryption

property-encryption object, optional

Specifies the configuration for encryption of the property in the repository. If omitted or null, the property is not encrypted.

isPersonal

boolean, true/false

Designed to highlight personally identifying information. By default, isPersonal is set to true for userName and postalAddress.

isProtected

boolean, true/false

Specifies whether reauthentication is required if the value of this property changes.

isVirtual

boolean, true/false

Specifies whether the property takes a static value, or whether its value is calculated dynamically as the result of a script.

The most recently calculated value of a virtual property is persisted by default. The persistence of virtual property values allows IDM to compare the new value of the property against the last calculated value, and therefore to detect change events during synchronization.

Virtual property values are not persisted by default if you are using an explicit mapping.

items

property-configuration object, optional

For array type properties, defines the elements in the array. items can include the following sub-properties:

id

urn, optional

The URN of the property, for example, urn:jsonschema:org:forgerock:openidm:managed:api:Role:members:items.

properties

property configuration object, optional

A list of properties, and their configuration, that make up this items array. For example, for a relationship type property:

"properties" : {
    "_ref" : {
        "description" : "References a relationship from a managed object",
        "type" : "string"
    },
    "_refProperties" : {
        "description" : "Supports metadata within the relationship",
        ...
    }
}

resourceCollection

property configuration object, optional

The collection of resources (objects) on which this relationship is based (for example, managed/user objects).

reversePropertyName

string, optional

For relationship type properties, specifies the corresponding property name in the case of a reverse relationship. For example, a roles property might have a reversePropertyName of members.

reverseRelationship

boolean, true or false.

For relationship type properties, specifies whether the relationship exists in both directions.

title

string, optional

The title of array items, as displayed in the UI, for example Role Members Items.

type

string, optional

The array type, for example relationship.

validate

boolean, true/false

For reverse relationships, specifies whether the relationship should be validated.

onRetrieve

script object, optional

A script object to trigger once a property is retrieved from the repository. That property may be one of two related variables: property and propertyName. The property that was retrieved is provided in the root scope as the propertyName variable; its value is provided as the property variable. If an exception is thrown, then object retrieval fails.

onStore

script object, optional

A script object to trigger when a property is about to be stored in the repository. That property may be one of two related variables: property and propertyName. The property that was retrieved is provided in the root scope as the propertyName variable; its value is provided as the property variable. If an exception is thrown, then object storage fails.

onValidate

script object, optional

A script object to trigger when the property requires validation. The value of the property to be validated is provided in the root scope as the property property. If an exception is thrown, validation fails.

pattern

string, optional

Any specific pattern to which the value of the property must adhere. For example, a property whose value is a date might require a specific date format. Patterns specified here must follow regular expression syntax.

policies

policy object, optional

Any policy validation that must be applied to the property.

required

boolean, true/false

Specifies whether the property must be supplied when an object of this type is created.

returnByDefault

boolean, true/false

For virtual properties, specifies whether the property will be returned in the results of a query on an object of this type if it is not explicitly requested. Virtual attributes are not returned by default.

scope

string, optional

Specifies whether the property should be filtered from HTTP/external calls. The value can be either "public" or "private". "private" indicates that the property should be filtered, "public" indicates no filtering. If no value is set, the property is assumed to be public and thus not filtered.

searchable

boolean, true/false

Specifies whether this property can be used in a search query on the managed object. A searchable property is visible in the End User UI. False by default.

secureHash

property-hash object, optional

Specifies the configuration for hashing of the property value in the repository. If omitted or null, the property is not hashed.

title

A human-readable string, used to display the property in the UI.

type

data type, required

The data type for the property value; can be String, Array, Boolean, Number, Object, or Resource Collection.

usageDescription

string, optional

Designed to help end users understand the sensitivity of a property such as a telephone number.

userEditable

The alias of the key in the IDM cryptography service keystore used to encrypt the property.

Property Hash Object

{
    "algorithm" : string,
    "type" : string
}

algorithm: string, required

The algorithm that should be used to hash the value.

For a list of supported hash algorithms, see Salted Hash Algorithms.
type: string, optional

The type of hashing. Currently only salted hash is supported. If this property is omitted or null, the default "salted-hash" is used.

Custom managed objects

Managed objects are inherently fully user definable and customizable. Like all objects, managed objects can maintain relationships to each other in the form of links. Managed objects are intended for use as targets and sources for synchronization operations to represent domain objects, and to build up virtual identities. The name managed objects comes from the intention that IDM stores and manages these objects, as opposed to system objects that are present in external systems.

IDM can synchronize and map directly between external systems (system objects), without storing intermediate managed objects. Managed objects are appropriate, however, as a way to cache the data—for example, when mapping to multiple target systems, or when decoupling the availability of systems—to more fully report and audit on all object changes during reconciliation, and to build up views that are different from the original source, such as transformed and combined or virtual views. Managed objects can also be allowed to act as an authoritative source if no other appropriate source is available.

Other object types exist for other settings that should be available to a script, such as configuration or look-up tables that do not need audit logging.

Set up a managed object type

To set up a managed object, you define the object in your project’s managed object configuration. This simple example adds a foobar object declaration after the user object type:

{
    "objects": [
        {
            "name": "user"
        },
        {
            "name": "foobar"
        }
    ]
}

Manipulate managed objects declaratively

By mapping an object to another object, either an external system object or another internal managed object, you automatically tie the object life cycle and property settings to the other object. For more information, see Resource mapping.

Manipulate managed objects programmatically

You can address managed objects as resources using URLs or URIs with the managed/ prefix. This works whether you address the managed object internally as a script running in IDM or externally through the REST interface.

You can use all resource API functions in script objects for create, read, update, delete operations, and also for arbitrary queries on the object set, but not currently for arbitrary actions. For more information, see Scripting.

IDM supports concurrency through a multi version concurrency control (MVCC) mechanism. Each time an object changes, IDM assigns it a new revision.

Objects can be arbitrarily complex as long as they use supported types, such as maps, lists, numbers, strings, and booleans as defined in JSON.

Create objects

The following script example creates an object type.

openidm.create("managed/foobar", "myidentifier", mymap)

Update objects

The following script example updates an object type.

var expectedRev = origMap._rev
openidm.update("managed/foobar/myidentifier", expectedRev, mymap)

The MVCC mechanism requires that expectedRev be set to the expected revision of the object to update. You obtain the revision from the object’s _rev property. If something else changes the object concurrently, IDM rejects the update, and you must either retry or inspect the concurrent modification.

Patch objects

You can partially update a managed or system object using the patch method, which changes only the specified properties of the object.

The following script example updates an object type.

openidm.patch("managed/foobar/myidentifier", rev, value)

The patch method supports a revision of "null", which effectively disables the MVCC mechanism, that is, changes are applied, regardless of revision. In the REST interface, this matches the If-Match: "*" condition supported by patch. Alternatively, you can omit the "If-Match: *" header.

For managed objects, the API supports patch by query, so the caller does not need to know the identifier of the object to change.

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--header "Content-Type: application/json" \
--request POST \
--data '[
  {
    "operation": "replace",
    "field": "/password",
    "value": "Passw0rd"
  }
]' \
"http://localhost:8080/openidm/managed/user?_action=patch&_queryFilter=userName+eq+'DDOE'"

Delete objects

The following script example deletes an object type.

var expectedRev = origMap._rev
openidm.delete("managed/foobar/myidentifier", expectedRev)

The MVCC mechanism requires that expectedRev be set to the expected revision of the object to update. You obtain the revision from the object’s _rev property. If something else changes the object concurrently, IDM rejects deletion, and you must either retry or inspect the concurrent modification.

Read objects

The following script example reads an object type.

val = openidm.read("managed/foobar/myidentifier")

Query object sets

You can query managed objects using common query filter syntax. The following script example queries managed user objects whose userName is smith.

var qry = {
    "_queryFilter" : "/userName eq \"smith\""
};
val = openidm.query("managed/user", qry);

For more information, see Define and call data queries.

Access managed objects through the REST API

IDM exposes all managed object functionality through the REST API unless you configure a policy to prevent such access. In addition to the common REST functionality of create, read, update, delete, patch, and query, the REST API also supports patch by query. For more information, see the REST API reference.

IDM requires authentication to access the REST API. The authentication configuration is specified in your project’s conf/authentication.json file. The default authorization filter script is openidm/bin/defaults/script/router-authz.js. For more information, see Authorization and roles.
