    Recipe and Ontology

    TypeRecommended
    Labels400 labels per ontology
    Attributes100 attributes per ontology

    Data-Management

    TypeLimit
    Items in the DatasetMaximum 25,000,000 items
    Annotations in joined queriesMaximum 7,000,000 items
    Unique custom metadata keys on items in datasetMaximum is 100 for searchable keys. To overcome this, refer to the Unsearchable Metadata article.
    Item JSON file sizeMaximum 100KB
    Maximum download file size from the platform2GB
    Schema enforcement in DatasetMetadata path must contain same value type across the dataset
    Search size per each search key/value1024 Bytes
    Item filename(full path including dirs)1024 chars
    Annotation label1024 chars
    Annotation attributesMax 100 per annotation

    Queries limitations:

    QueryLimit
    Maximum total filter terms in a query20 terms
    Maximum metadata filter terms in a query10 terms
    Max sort terms in a query3 terms
    Sorting over custom metadata1 term
    Filter by annotation MetadataNot supported
    • Dataloop permits the storage and querying of over 25,000,000 items and unlimited annotations in a dataset, However, join queries between items and annotations are limited to searching over max 7M annotations.
    • A Term refers to an individual element or condition used in the query to filter, sort, or search for data. Each term typically represents a distinct criterion or parameter that helps refine the results of a query.

    Supported File Formats

    TypeRecommended
    ImageJPG, JPEG, PNG, TIFF
    VideoWEBM, MP4, MOV
    AudioWAV, MP3, OGG, FLAC*, M4A, AAC
    LidarPCD
    NLP / NERTXT, JSON, EML, PDF
    Note
    • Audio Studio: The FLAC format is a lossless audio format that preserves the original audio quality without any degradation. To reduce file size and improve platform performance, we recommend converting FLAC files to MP3.
    • Video Studio: Dataloop supports various file types as mentioned above, but the video annotation will be performed on WEBM format. For more information, see the WEBM article.

    Image Item

    TypeRecommended
    Size15 MB
    FormatsRefer to the Supported File Formats section.
    Resolution24.0 MP
    Total annotations1,000

    Valid EXIF values are 1 to 8. Values outside this range (for example, 0) are ignored.
    Read more about Exif orientation values.

    Audio Item

    TypeRecommended
    AnnotationsUp to 300
    Recommended formatRefer to the Supported File Formats section.
    Recommended audio sizeUp to 100 MB
    Important

    A 20-minute audio file may be larger than a 1-hour file, as audio file size depends on factors like bitrate, compression, encoding settings, format, sample rate, and audio complexity. Thus, a 17-minute file can surpass a 1-hour one if it has a higher bitrate or less efficient compression.

    Video Item

    TypeRecommended
    LengthUnder 5 minutes and 30 FPS
    Recommended formatRefer to the Supported File Formats section.
    Recommended storageDataloop Storage
    Recommended video size50 MB
    Total annotationsUp to 200

    Storing videos on external cloud storage (S3/GCS/Azure) can lead to latency issues when serving videos to annotators. For optimal video annotation performance, it is recommended to store video files on Dataloop's storage.

    Maximum unworked items per task (without Status)80,000
    Maximum assignees per task1,000
    Maximum tasks per project5,000
