Resources

Generic resources are rooted in the /v1/resources/{org_label}/{project_label}/{schema_id} collection.

Each resource…

  • belongs to a project identifier by the label {project_label}
  • inside an organization identifier by the label {org_label}
  • it is validated against a schema with id {schema_id}. In case of using _ for this segment, the schema segment reads as irrelevant.
Authorization notes

When modifying resources, the caller must have resources/write permissions on the current path of the project or the ancestor paths.

When reading resources, the caller must have resources/read permissions on the current path of the project or the ancestor paths.

Please visit Authentication & authorization section to learn more about it.

Note

From Delta v1.5, remote contexts are only resolved during creates and updates. That means that when those get updated, the resources importing them must be also updated to take them into account the new version.

Indexing

All the API calls modifying a resource (creation, update, tagging, deprecation) can specify whether the resource should be indexed synchronously or in the background. This behaviour is controlled using indexing query param, which can be one of two values:

  • async - (default value) the resource will be indexed asynchronously
  • sync - the resource will be indexed synchronously and the API call won’t return until the indexing is finished

Create using POST

POST /v1/resources/{org_label}/{project_label}/{schema_id}
  {...}

The json payload:

  • If the @id value is found on the payload, this @id will be used.
  • If the @id value is not found on the payload, an @id will be generated as follows: base:{UUID}. The base is the prefix defined on the resource’s project ({project_label}).

Create using PUT

This alternative endpoint to create a resource is useful in case the json payload does not contain an @id but you want to specify one. The @id will be specified in the last segment of the endpoint URI.

PUT /v1/resources/{org_label}/{project_label}/{schema_id}/{resource_id}
  {...}

Note that if the payload contains an @id different from the {resource_id}, the request will fail.

Update

This operation overrides the payload.

In order to ensure a client does not perform any changes to a resource without having had seen the previous revision of the resource, the last revision needs to be passed as a query parameter.

PUT /v1/resources/{org_label}/{project_label}/{schema_id}/{resource_id}?rev={previous_rev}
  {...}

… where {previous_rev} is the last known revision number for the resource.

Deprecate

Locks the resource, so no further operations can be performed. It also deletes the resource from listing/querying results.

Deprecating a resource is considered to be an update as well. 

DELETE /v1/resources/{org_label}/{project_label}/{schema_id}/{resource_id}?rev={previous_rev}

… where {previous_rev} is the last known revision number for the resource.

List

There are three available endpoints to list resources in different scopes.

Within a project

GET /v1/resources/{org_label}/{project_label}?from={from}
                                             &size={size}

                                             &sort={sort}

Within an organization

This operation returns only resources from projects defined in the organisation {org_label} and where the caller has the resources/read permission.

GET /v1/resources/{org_label}?from={from}
                             &size={size}
                             &deprecated={deprecated}

                             &sort={sort}

Within all projects

This operation returns only resources from projects where the caller has the resources/read permission.

GET /v1/resources?from={from}
                 &size={size}
                 &deprecated={deprecated}

Parameter description

  • {from}: Number - is the parameter that describes the offset for the current query; defaults to 0
  • {size}: Number - is the parameter that limits the number of results; defaults to 20
  • {deprecated}: Boolean - can be used to filter the resulting resources based on their deprecation status
  • {rev}: Number - can be used to filter the resulting resources based on their revision value
  • {type}: Iri - can be used to filter the resulting resources based on their @type value. This parameter can appear multiple times, filtering further the @type value.
  • {createdBy}: Iri - can be used to filter the resulting resources based on their creator
  • {updatedBy}: Iri - can be used to filter the resulting resources based on the person which performed the last update
  • {schema}: Iri - can be used to filter the resulting resources based on the conformant schema
  • {search}: String - can be provided to select only the resources in the collection that have attribute values matching (containing) the provided string
  • {sort}: String - can be used to sort resources based on a payloads’ field. This parameter can appear multiple times to enable sorting by multiple fields. The default is done by _createdBy and @id.

Parameter description

  • {from}: Number - is the parameter that describes the offset for the current query; defaults to 0
  • {size}: Number - is the parameter that limits the number of results; defaults to 20
  • {deprecated}: Boolean - can be used to filter the resulting resources based on their deprecation status
  • {rev}: Number - can be used to filter the resulting resources based on their revision value
  • {type}: Iri - can be used to filter the resulting resources based on their @type value. This parameter can appear multiple times, filtering further the @type value.

Server Sent Events

GET /v1/resources/events                              # for all resource events in the application
GET /v1/resources/{org_label}/events                  # for resource events in the given organization
GET /v1/resources/{org_label}/{project_label}/events  # for resource events in the given project

The caller must have respectively the events/read permission on /, {org_label} and {org_label}/{project_label}.

  • {org_label}: String - the selected organization for which the events are going to be filtered
  • {project_label}: String - the selected project for which the events are going to be filtered
  • Last-Event-Id: String - optional HTTP Header that identifies the last consumed resource event. It can be used for cases when a client does not want to retrieve the whole event stream, but to start after a specific event.

The server sent events response contains a series of resource events, represented in the following way

data:{payload}
event:{type}
id:{id}

where…

  • {payload}: Json - is the actual payload of the current resource
  • {type}: String - is a type identifier for the current resource. Possible types are related to core resource types (Resouce, Schema, Resolver) and available plugin types
  • {id}: String - is the identifier of the resource event. It can be used in the Last-Event-Id query parameter
