# ListObjects

Returns a list of objects in a specified database. The action can also return information about the images, training options, and metadata associated with each object.

Type: synchronous

Parameter | Description | Required
--- | --- | ---
`database` | The name of the database that contains the objects. | Yes
`identifier` | A comma-separated list of identifiers to specify the objects to list. If you do not set this parameter, Media Server lists all of the objects in the specified database. | No
`imagestatus` | A Boolean value (default false) that specifies whether to return the label and training status of each image associated with each object. | No
`maxresults` | The maximum number of objects to return. | No
`metadata` | A Boolean value (default false) that specifies whether to return the metadata associated with each object. | No
`start` | The starting point for the list when you set the `maxresults` parameter. For example, to start listing objects from the tenth object in the database, set `start=10`. The entries in the database are indexed from 1. | No
`trainingoptions` | A Boolean value (default false) that specifies whether to return the training options set for each object. | No

## Example

The following example lists up to 10 objects contained in the `CompanyLogos` database:

    /action=ListObjects&database=CompanyLogos
                       &imagestatus=TRUE
                       &metadata=TRUE
                       &trainingoptions=TRUE
                       &start=1
                       &maxresults=10

## Response

The response always includes the following information for each object:

- `identifier` - The identifier for the object.
- `numimages` - The number of training images associated with the object.
- `numtrained` - The number of images associated with the object that have been trained (the number that are used for object recognition).
- `numfailed` - The number of images associated with the object where training failed.
- `numuntrained` - The number of images associated with the object that have not yet been trained.

If you set the action parameter `imagestatus` to `true`, Media Server returns the status of each training image associated with each object.

- The `status` element indicates the status of training:

  - `trained` indicates that training was successful.
  - `untrained` indicates that training has not been attempted. Run training for the object using the action BuildObject, or run training for all objects that have incomplete training using the action BuildAllObjects.
  - `failed` indicates that Media Server could not use the image for training. Remove the failed image using the action RemoveObjectImages.
- The `hasimagedata` element indicates whether the training image is stored in the database. If the value of this element is `false`, the image has been removed from the database by the action NullObjectImageData. Images that have been removed and have a status of `untrained` cannot be trained, so OpenText recommends you remove these images with the action RemoveObjectImages.
