Data Management and Curation

STEP 1: Register Cloud Data with Encord
Create a Cloud Integration
Select your cloud provider.Create a Folder
You must create a folder in Index to store your files.- Navigate to Files under the Index heading in the Encord platform.
- Click the + New folder button to create a new folder. Select the type of folder you want to create.

- Give the folder a meaningful name and description.
- Click Create to create the folder. The folder is listed in Files.
Create JSON or CSV for Registration
To register files from cloud storage with Encord, you must create a JSON or CSV file specifying the files you want to register.Find helpful scripts for creating JSON and CSV files for the cloud data registration process here.
For a list of supported file formats for each data type, go here
Encord supports file names up to 300 characters in length for any file or video for upload.
Encord enforces the following upload limits for each JSON file used for file registration:
- Up to 1 million URLs
- A maximum of 500,000 items (e.g. images, image groups, videos, DICOMs)
- URLs can be up to 16 KB in size
BEST PRACTICE: If you want to use Index or Active with your video data, we STRONGLY RECOMMEND using custom metadata (
clientMetadata
) to specify key frames, custom metadata, and custom embeddings. For more information go here or here for information on using the SDK.JSON Format

Image groups
For detailed information about the JSON file format used for import go here.- Image groups are collections of images that are processed as one annotation task.
- Images within image groups remain unaltered, meaning that images of different sizes and resolutions can form an image group without the loss of data.
- Image groups do NOT require ‘write’ permissions to your cloud storage.
- If
skip_duplicate_urls
is set totrue
, all URLs exactly matching existing image groups in the dataset are skipped.
The position of each image within the sequence needs to be specified in the key (
objectUrl_{position_number}
).- Data: Imports the image groups only.
Image sequences
Image sequences
Image sequences
For detailed information about the JSON file format used for import go here.- Image sequences are collections of images that are processed as one annotation task and represented as a video.
- Images within image sequences may be altered as images of varying sizes and resolutions are made to match that of the first image in the sequence.
- Creating Image sequences from cloud storage requires ‘write’ permissions, as new files have to be created in order to be read as a video.
- Each object in the
image_groups
array with thecreateVideo
flag set totrue
represents a single image sequence. - If
skip_duplicate_urls
is set totrue
, all URLs exactly matching existing image sequences in the dataset are skipped.
The only difference between adding image groups and image sequences using a JSON file is that image sequences require the
createVideo
flag to be set to true
. Both use the key image_groups
.The position of each image within the sequence needs to be specified in the key (
objectUrl_{position_number}
).Encord supports up to 32,767 entries (21:50 minutes) for a single image sequence. We recommend up to 10,000 to 15,000 entries for a single image sequence for best performance. If you need a longer sequence, we recommend using video instead of an image sequence.
- Data: Imports the images groups only.
DICOM
DICOM
DICOM
For detailed information about the JSON file format used for import go here.- Each
dicom_series
element can contain one or more DICOM series. - Each series requires a title and at least one object URL, as shown in the example below.
- If

is set totrue
, all object URLs exactly matching existing DICOM files in the dataset will be skipped.
Custom metadata is distinct from patient metadata, which is included in the
.dcm
file and does not have to be specific during the upload to Encord. - The first series contains only a single object URL, as it is composed of a single file.
- The second series contains 3 object URLs, as it is composed of three separate files.
- The third series contains 2 object URLs, as it is composed of two separate files.
For each DICOM upload, an additional
DicomSeries
file is created. This file represents the series file-set. Only DicomSeries
are displayed in the Encord application.Template

STEP 2: Curate your Data
Curation of your data consists of sorting, filtering, using analytics, and embedding plots to create one or more Collections. Collections can then be made into a Dataset for use with your Annotate and Active Projects.1
Filter and Sort Data
You can sort your data using a number of data unit metrics. The metrics available to sort your data depends on the data available in the Folder. You can sort your data in ascending and descending order.Index has a number of criteria available to filter your data. You can only access filtering criteria that is available from the top-level Folder. For example, if you do not have any video or audio data in the top-level Folder or any sub-Folders, you cannot filter your data using those filtering criteria.
Adding key frames (for videos), custom metadata, and custom embeddings) to your data can all significantly improve the speed and effectiveness when filtering your data. We recommend importing customer metadata and custom embeddings with your data, but you can import custom metadata and embeddings after importing your data.
