This endpoint will return the specified resource in the specified repository.

For example, if the repository Id is imodels then it will return the id and displayName of the specified iModel. It will only return the iModel information if the user has permission to view it. For some resources, it will also return capabilities.graphics.uri that can be used to locate graphics for the resource.

iModels
RealityData
GeospatialFeatures
CesiumCuratedContent
PdfPlansets
GeographicInformationSystem

Definitions

Resource

String

The resource Id. For example, for the iModels repository, this would be an iModel Id. For the CesiumCuratedContent repository, this would be the content Id. Each repository defines it's own id format. Treat it as a string and do not assume it will be a GUID or integer.

class

ResourceClass

The resource class. This value is copied from the repository.

subClass

ResourceSubClass

The resource class. This value is copied from the repository and may be empty.

type

String

The type of resource as specified by the repository. This is not a fixed list. The values are specific to each respository and not every repository will specify a resource type. In that case, the type property will not be included in the response.

displayName

String

The resource name that can be displayed to the user.
