Resolvers

Resolvers are rooted in the /v1/resolvers/{org_label}/{project_label} collection and are used in the following scenarios:

  • Bring the content of the owl:imports predicate for schema resources. The value is the @id of the resource. E.g.: You can define owl imports on a schema, as follows "owl:imports": "http://example.com/myid". The resolver will try to find a resource with "@id": "http://example.com/myid" and if found, will bring the payload into the original resource.
  • Bring the content of the @context links. The value is the @id of the resource. E.g.: A resource might define the context as follows: "@context": "http://example.com/id". The resolver will try to find a resource with "@id": "http://example.com/id" and if found, will bring the payload into the original resource.

Each resolver belongs to a project identifier by the label {project_label} inside an organization identifier by the label {org_label}.

Authorization notes

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

When reading resolvers, 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.

Resolver types

There are several types of resolvers, which perform resolution in different scopes.

InProject resolver

The scope of the resolution is the current project where the resource resides. In other words:

  • Schema A can import schema B using the owl:imports as long as schema B is located on the same project as schema A.
  • Resource A can reference to a remote context existing in resource B as long as resource B is located on the same project as resource A.

This resolver gets automatically created when the project is created and has the highest priority for resolution. It should not be modified.

InProject resolver payload

{
    "@id": "https://bluebrain.github.io/nexus/vocabulary/defaultInProject",
    "@type": "InProject",
    "priority": {priority},
}

where {priority} is a numeric value (from 0 - 1000) which defines the resolution priority when attempting to find the resource with a particular @id.

CrossProject resolver

The scope of the resolution is the collections of projects P defined on the resolver. CrossProject resolution also defines a identity policy I (via the identities or the useCurrentCaller fields) to enforce ACLs. In other words:

  • Schema A can import schema B using the owl:imports as long as schema B is located in some of the projects from the collection P and as long I have resources/read permissions on the schema B project.
  • Resource A can reference to a remote context existing in resource B as long as resource B is located in some of the projects from the collection P and as long as I have resources/read permissions on the schema B project.

CrossProject resolver payload

{
  "@id": "{someId}",
  "@type": ["Resolver", "CrossProject"],
  "priority": {priority}
  "resourceTypes": ["{resourceType}", ...],
  "projects": ["{project}", ... ],
  "identities": [ {identity}, {...} ],
  "useCurrentCaller": {useCurrentCaller},
}

where…

  • {someId}: Iri - the @id value for this resolver.
  • {priority}: Number - value (from 0 - 1000) which defines the resolution priority when attempting to find the resource. All resolvers must have a different priority in a same project
  • {resourceType}: Iri - resolves only the resources with @type containing {resourceType}. This field is optional. with a particular @id.
  • {project}: String - the user friendly reference to the project from where the resolution process will attempt to find the @id’s. It follows the format {organization}/{project}.
  • {identity}: Json object - the identity against which to enforce ACLs during resolution process. Can’t be defined if useCurrentCaller is set to true
  • {useCurrentCaller}: Boolean - the resolution process will use the caller and its identitites to enforce acls. Can’t be true when _identity_ is defined.

Indexing

All the API calls modifying a resolver (creation, update, tagging, deprecation) can specify whether the resolver 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 resolver will be indexed asynchronously
  • sync - the resolver will be indexed synchronously and the API call won’t return until the indexing is finished

Create using POST

POST /v1/resolvers/{org_label}/{project_label}
  {...}

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 resolver’s project ({project_label}).

Create using PUT

This alternative endpoint to create a resolver 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/resolvers/{org_label}/{project_label}/{resolver_id}
  {...}

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

Update

This operation overrides the payload.

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

PUT /v1/resolvers/{org_label}/{project_label}/{resolver_id}?rev={previous_rev}
  {...}

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

Example

Tag

Links a resolver revision to a specific name.

Tagging a resolver is considered to be an update as well.

POST /v1/resolvers/{org_label}/{project_label}/{resolver_id}/tags?rev={previous_rev}
  {
    "tag": "{name}",
    "rev": {rev}
  }

… where

  • {previous_rev}: Number - the last known revision for the resolver.
  • {name}: String - label given to the resolver at specific revision.
  • {rev}: Number - the revision to link the provided {name}.

}

Deprecate

Locks the resolver, so no further operations can be performed. It will also not be taken into account in the resolution process.

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

DELETE /v1/resolvers/{org_label}/{project_label}/{resolver_id}?rev={previous_rev}

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

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 resolvers based on their deprecation status
  • {rev}: Number - can be used to filter the resulting resolvers based on their revision value
  • {type}: Iri - can be used to filter the resulting resolvers 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 resolvers based on their creator
  • {updatedBy}: Iri - can be used to filter the resulting resolvers based on the person which performed the last update
  • {search}: String - can be provided to select only the resolvers in the collection that have attribute values matching (containing) the provided string
  • {sort}: String - can be used to sort resolvers 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.

Fetch resource using resolvers

Fetches a resource using the provided resolver.

If the resolver segment ({resolver_id}) is _ the resource is fetched from the first resolver in the requested project ({org_label}/{project_label}). The resolvers are ordered by its priority field.

GET /v1/resolvers/{org_label}/{project_label}/{resolver_id}/{resource_id}?rev={rev}
                                                                         &tag={tag}
                                                                         &showReport={showReport}

… where

  • {resource_id}: Iri - the @id value of the resource to be retrieved.
  • {rev}: Number - the targeted revision to be fetched. This field is optional and defaults to the latest revision.
  • {tag}: String - the targeted tag to be fetched. This field is optional.
  • {showReport}: Boolean - return the resolver resolution steps instead of the resource for debugging purposes.

{rev} and {tag} fields cannot be simultaneously present.

Server Sent Events

From Delta 1.5, it is possible to fetch SSEs for all resolvers or just resolvers in the scope of an organization or a project.

GET /v1/resolvers/events # for all resolver events in the application
GET /v1/resolvers/{org_label}/events # for resolver events in the given organization
GET /v1/resolvers/{org_label}/{project_label}/events # for resolver 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.
Note

The event type for resolvers SSEs have been changed so that it is easier to distinguish them from other types of resources.
