Items
The best way to look at items in the Dataloop platform are annotated files that comes with some extra capabilities:
- Items and Annotations have Metadata attached to them
- Items are essentially pointers to binary storage
- Item have a collection of Annotations attached to them
- Item and Annotations are searchable, including custom metadata properties
Dataloop handles items in the same manner as OS handle files; in other words, different item types are being displayed using the appropriate (data) application where the default viewers already support:
- Image files
- Video files
- Audio files
- Text/Code files
- Shebang Items like Similarity.
Supported Formats
For Images:- 'jpeg', 'jpg', 'png', 'webp', 'tiff', 'tif', 'bmp', 'jfif'
For Videos:- 'mp4', 'mkv', 'webm', 'avi'
For Audio:- 'mp3', 'ogg', 'wav'
JSON files like in annotations and items are also supported.
JSON Code For Items
Each entity in our system has a JSON code that represents its data within our system.
It includes the entity's data related to our software and its metadata.
JSON is a minimal text-based data exchange format that is used primarily to transmit data between a server and web application
