| Items in the Dataset | Maximum 25,000,000 items |
| Annotations in joined queries | Maximum 7,000,000 items |
| Unique custom metadata keys on items in dataset | Maximum is 100 for searchable keys. To overcome this, refer to the Unsearchable Metadata article. |
| Item JSON file size | Maximum 100KB |
| Maximum download file size from the platform | 2GB |
| Schema enforcement in Dataset | Metadata path must contain same value type across the dataset |
| Search size per each search key/value | 1024 Bytes |
| Item filename(full path including dirs) | 1024 chars |
| Annotation label | 1024 chars |
| Annotation attributes | Max 100 per annotation |
Queries limitations:
| Query | Limit |
|---|---|
| Maximum total filter terms in a query | 20 terms |
| Maximum metadata filter terms in a query | 10 terms |
| Max sort terms in a query | 3 terms |
| Sorting over custom metadata | 1 term |
| Filter by annotation Metadata | Not 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
| Type | Recommended |
|---|---|
| Image | JPG, JPEG, PNG, and TIFF |
| Video | WEBM, MP4, and MOV |
| Audio | WAV, MP3, OGG, FLAC, M4A, and AAC |
| Lidar | PCD (ASCII format with a size limit of 70 MB) |
| NLP / NER | TXT, JSON, EML, and PDF |
| GIS | COG, GeoTIFF, OSM, and XYZ |
Important
- Audio Studio: FLAC is a lossless audio format that maintains the original quality without degradation. To optimize file size and 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.
- MP4 Limitations: The SAR/DAR values are not supported for MP4 files.
Image Item
| Type | Recommended |
|---|---|
| Size | 15 MB |
| Formats | Refer to the Supported File Formats section. |
| Resolution | 24.0 MP |
| Total annotations | 1,000 |
Valid EXIF values are 1 to 8. Values outside this range (for example, 0) are ignored.
Read more about Exif orientation values.
Audio Item
| Type | Recommended |
|---|---|
| Annotations | Up to 300 |
| Recommended format | Refer to the Supported File Formats section. |
| Recommended audio size | Up 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.
