Changed for APIs in 26.4, Sub Labels
In addition to the schemas described in Changed APIs in 26.4.0 (Schemas) these are the changes related to the property sub_labels.
Property sub_labels
Adding sub_labels introduces multi-dimensional, nested metadata sets into workloads.
Instead of a flat list of tags, workloads can now support groups of nested label collections.
vens_get
This schema update aligns the VEN retrieval API with multi-dimensional metadata tracking by introducing a sub_labels property for workloads associated with a VEN.
{
"properties": {
"workloads": {
"items": {
"properties": {
"sub_labels": {
"description": "List of sub-label sets associated with this workload",
"type": [
"array",
"null"
],
"items": {
"description": "A sub-label set associated with this workload",
"type": "array",
"items": {
"type": "object",
"required": [
"href",
"key",
"value"
],
"properties": {
"href": {
"description": "The URI of the label.",
"type": "string"
},
"key": {
"description": "Key of the label",
"type": "string"
},
"value": {
"description": "Value of the label",
"type": "string"
}
}
}
}
}
}
}
}
}
}Nullable Array of Arrays Structure: The sub_labels property is typed as ["array", "null"], making it optional or nullable.
Inline Key-Value Pair Definition: Each item within the nested array is an object representing an individual label instance. The schema enforces a strict object structure requiring three fields:
href: The unique URI/API path of the label (string).
key: The dimension or category of the label (string).
value: The specific assignment name of the label (string).
workloads_get
This update refines the workload retrieval data model (workloads_get) by standardizing label metadata and officially supporting nested sub-labels.
It introduces a new sub-labels array and fixes a documentation bug in the existing core labels object.
{
"properties": {
"sub_labels": {
"description": "List of sub-label sets associated with this workload",
"type": "array",
"items": {
"description": "A sub-label set associated with this workload",
"type": "array",
"items": {
"type": "object",
"required": [
"href",
"key",
"value"
],
"properties": {
"href": {
"description": "The URI of the label.",
"type": "string"
},
"key": {
"description": "Key of the label",
"type": "string"
},
"value": {
"description": "Value of the label",
"type": "string"
}
}
}
}
},
"labels": {
"items": {
"properties": {
"href": {
"description": {
"__old": "The URI of the VEN that manages this workload. This replaces the 'agent' field of this object.",
"__new": "The URI of the label."
}
}
}
}
}
}
}The schema fixes an incorrect legacy description.
The href inside the core labels block was erroneously documented as pointing to a VEN/Agent management URI, but it actually references the label's own URI. Correcting the documentation block prevents confusion for developers when integrating with the core labels object array.
workloads_post
This update introduces support for nested metadata during workload creation (workloads_post) by adding a new property, sub_labels, to the request payload configuration.
{
"properties": {
"sub_labels": {
"description": "List of sub-label sets associated with the workload",
"type": "array",
"items": {
"$ref": "labels.schema.json"
}
}
}
}Addition of a Sub-Label Array: The schema introduces a new property named sub_labels
Structural Reference ($ref): The creation payload defines this field as an "array" whose items reference an existing core schema file: labels.schema.json.
This allows API clients to assign a structured collection or list of nested sub-label sets directly when a new workload is provisioned.
workloads_with_ven_interface_put
This update introduces support for updating nested metadata on workloads paired with VEN network interfaces (workloads_with_ven_interfaces_put) by adding the sub_labels property to the update payload.
{
"properties": {
"sub_labels": {
"description": "List of sub-label sets associated with the workload",
"type": "array",
"items": {
"$ref": "labels.schema.json"
}
}
}
}workloads_with_ven_put
This update introduces support for modifying nested metadata on standard VEN-managed workloads (workloads_with_ven_put) by adding the sub_labels property to the update payload.
Consistent with the other write/update endpoints (workloads_post and workloads_with_ven_interfaces_put), this array references the core external schema file: labels.schema.json.
{
"properties": {
"sub_labels": {
"description": "List of sub-label sets associated with the workload",
"type": "array",
"items": {
"$ref": "labels.schema.json"
}
}
}
}workloads_without_ven_put
This update introduces support for modifying nested metadata on unmanaged or agentless workloads (workloads_without_ven_put) by adding the sub_labels property to the update payload.
This allows API clients to update, append to, or overwrite a structured collection of sub-label sets on workloads without a Virtual Enforcement Node installed (e.g., third-party appliances, legacy systems, or static network targets).
{
"properties": {
"sub_labels": {
"description": "List of sub-label sets associated with the workload",
"type": "array",
"items": {
"$ref": "labels.schema.json"
}
}
}
}
