This JSON code includes the entity's data related to our software and its metadata. The Video Annotation JSON file records KeyFrames and automated frames, not reflected frames. In other words, an annotation in a specific frame that has not changed since the previous frame is not recorded in the JSON file. If the annotation is not the same as in the previous frame (for example, due to change in position, label, attribute, etc.), the annotation is recorded in the JSON file. - Read more about different types of frames at [Understanding KeyFrames, Interpolation, and Tracking](https://docs.dataloop.ai/docs/video-interpolation-tracking). - To download the JSON file of an item’s annotations, see [Export selected/queried items](https://docs.dataloop.ai/docs/download-data#export-selectedqueried-items). Important DDOE recommends you read frame through the SDK, as it allows you to read annotations at any frame/point in time, even in reflected frames (which are not recorded in the JSON). ``` { "annotations": [ { // Item metadata (the video file being annotated) "id": "67cf2185f561d468353ad582", // Unique ID of the video item "datasetId": "67cf2015fcc9e5df26713ad5", // Dataset ID this item belongs to "url": "https://gate.dataloop.ai/api/v1/items/67cf2185f561d468353ad582", // API URL to access this item "dataset": "https://gate.dataloop.ai/api/v1/datasets/67cf2015fcc9e5df26713ad5", // API URL of the dataset "createdAt": "2025-03-10T17:29:40.993Z", // Timestamp when item was created "dir": "/", // Directory path in the dataset "filename": "/video.webm", // Full filename with path "type": "file", // Item type (file) "hidden": false, // Visibility flag "metadata": { "fps": 59.94006309148265, // Frames per second "startTime": 0, // Start time in seconds "system": { "duration": 13.514, // Video duration in seconds "encoding": "7bit", // File encoding "ffmpeg": { // FFmpeg-extracted metadata about the video stream "codec_name": "vp9", // Codec used "coded_width": 768, // Width of video frames "coded_height": 432, // Height of video frames "pix_fmt": "yuv420p", // Pixel format "r_frame_rate": "19001/317", // Raw frame rate ratio "tags": { "DURATION": "00:00:13.514000000", // Duration as string "ENCODER": "Lavc60.31.102 libvpx-vp9" // Encoder used } }, "format": { "bit_rate": "867322", // Bitrate in bits per second "duration": "13.554000", // Format-level duration "format_name": "matroska,webm", // File format "size": "1469461" // File size in bytes }, "mimetype": "video/webm", // MIME type "originalname": "video.webm", // Original filename "thumbnailId": "67cf2187c3d298a06ce46b4f", // ID of generated thumbnail "width": 768, // Display width "height": 432 // Display height } }, "name": "video.webm", // Display name "creator": "user@dataloop.ai", // Item creator "updatedAt": "2025-03-10T17:29:45.059Z", // Last update time "updatedBy": "pipelines@dataloop.ai", // User or service that updated "stream": "https://gate.dataloop.ai/api/v1/items/67cf2185f561d468353ad582/stream", // Video stream endpoint "thumbnail": "https://gate.dataloop.ai/api/v1/items/67cf2185f561d468353ad582/thumbnail", // Thumbnail preview "annotations": [ { // Annotation 1: Polygonal segment (used for shape tracking or segmentation) "id": "67cf21eb47ee89b8f70be123", "type": "segment", // Type: segmented polygon "label": "Male", // Assigned label/class "coordinates": [ [ { "x": ..., "y": ... }, ... ] // List of polygon vertices (single frame) ], "metadata": { "system": { "frame": 0, // Starting frame "endFrame": 809, // Ending frame "startTime": 0, // Start time in seconds "endTime": 13.50932845639703, // End time in seconds "automated": false, // Not generated automatically "coordinateVersion": "v1", // Annotation version format "recipeId": "67cf2016930b028030d4b87c" // Labeling recipe ID } }, "creator": "user@dataloop.ai", // Who created this annotation "createdAt": "2025-03-10T17:31:23.476Z", "updatedBy": "user@dataloop.ai", "updatedAt": "2025-03-10T17:31:23.476Z", "source": "ui" // Annotation made via user interface }, { // Annotation 2: Bounding box annotation "id": "67cf21eb47ee89ee610be122", "type": "box", // Type: bounding box "label": "Male", "coordinates": [ { "x": 124.61, "y": 23.31, "z": 0 }, // Top-left corner { "x": 430.64, "y": 429.06, "z": 0 } // Bottom-right corner ], "metadata": { "system": { "frame": 0, "endFrame": 809, "startTime": 0, "endTime": 13.50932845639703, "automated": false, "coordinateVersion": "v2", "recipeId": "67cf2016930b028030d4b87c" } }, "creator": "user@dataloop.ai", "createdAt": "2025-03-10T17:31:23.476Z", "updatedBy": "user@dataloop.ai", "updatedAt": "2025-03-10T17:31:23.476Z", "source": "ui" } ], "annotationsCount": 2, // Total number of annotations on the video "annotated": true // Flag indicating item has been annotated } ] } ``` #### 📌 Key Video-Specific Highlights - Segment annotations (`type: "segment"`) use polygon points per frame to outline objects. - Box annotations (`type: "box"`) define regions using two corner points. - Temporal metadata like `startTime`, `endTime`, `frame`, and `endFrame` is critical for video. - `fps` and `duration` help sync annotation timing with video playback. - Annotations can span the entire video or specific frame ranges. --- ## RLHF Annotation Output This page describes RLHF JSON, a data format for describing RLHF data in JavaScript Object Notation (JSON). For more information on RLHF Studio, see the [RLHF Studio](https://docs.dataloop.ai/docs/rlhf). #### File or Prompt Layer Format The following format is a data structure example of a file that contains two prompts. The first prompt contains text and an image, and the second prompt contains text only. ``` { // Shebang indicates the Dataloop schema or format identifier "shebang": "dataloop", "metadata": { // 'dltype' declares this file contains prompt-style annotations "dltype": "prompt" }, "prompts": { // Each key (e.g., 'prompt1', 'prompt2') represents a separate prompt sample "prompt1": [ { // The first element of the prompt: a natural language question "mimetype": "application/text", // Indicates this is plain text "value": "What animal is in this image?" // Human-readable prompt question }, { // The second element of the prompt: a linked image input "mimetype": "image/jpeg", // MIME type indicating image format "value": "https://gate.dataloop.ai/api/v1/items/6489600c8d5a1c350e55116a/stream" // URL to stream the image (i.e., input data for the prompt) } ], "prompt2": [ { // Another prompt that only contains a text question without an image "mimetype": "application/text", "value": "What is the eye color of this cat?" // This could potentially be followed by an image or another data type in full usage } ] } } ``` #### 📌 Explanation - This structure is used for multi-modal prompts in RLHF workflows, especially combining `text + images`. - Each prompt consists of one or more data components, each defined by its `mimetype` and `value`. - This flexible format allows extending prompts with additional media types (e.g., audio, video). #### Annotations or Response Layer Format Data structure of a response. ``` { // Metadata about the annotated file (e.g., the JSON prompt file) "id": "64899218661aa36a1744112c", // Unique ID of the item "datasetId": "64885c4d71e85c4f03c3758c", // ID of the dataset to which this item belongs "url": "https://rc-gate.dataloop.ai/api/v1/items/64899218661aa36a1744112c", // API endpoint to access the item "dataset": "https://rc-gate.dataloop.ai/api/v1/datasets/64885c4d71e85c4f03c3758c", // API endpoint for the dataset "createdAt": "2023-06-14T10:10:32.863Z", // Timestamp when the item was created "dir": "/image_prompts", // Directory path in the dataset "filename": "/image_prompts/flyingdog.json", // Full path and filename "type": "file", // File type (in this case, a JSON file) "hidden": false, // Visibility flag "metadata": { "system": { "encoding": "7bit", // File encoding type "isBinary": false, // Indicates the file is not binary "mimetype": "application/json", // MIME type of the file "originalname": "flyingdog.json", // Original name at upload "refs": [], // Reference links to other items (if any) "shebang": { "dltype": "prompt" // Declares this is a prompt-type data item }, "size": 161, // Size of the file in bytes "taskStatusLog": [] // Log of tasks run on the item (empty here) } }, "name": "flyingdog.json", // Display name of the item "creator": "user@dataloop.ai", // Creator of the file "stream": "https://rc-gate.dataloop.ai/api/v1/items/64899218661aa36a1744112c/stream", // File stream endpoint "thumbnail": "https://rc-gate.dataloop.ai/api/v1/items/64899218661aa36a1744112c/thumbnail", // Thumbnail preview URL // The list of annotations associated with the item "annotations": [ { "id": "64899219bf9b191be0acdd2c", // Unique annotation ID "datasetId": "64885c4d71e85c4f03c3758c", // Same dataset as parent item "itemId": "64899218661aa36a1744112c", // ID of the item being annotated "url": "https://rc-gate.dataloop.ai/api/v1/annotations/64899219bf9b191be0acdd2c", // API URL to the annotation "item": "https://rc-gate.dataloop.ai/api/v1/items/64899218661aa36a1744112c", // Redundant link to item "dataset": "https://rc-gate.dataloop.ai/api/v1/datasets/64885c4d71e85c4f03c3758c", // Redundant link to dataset "type": "binary", // Annotation type: binary classification (used for response scoring, e.g., "yes/no", "good/bad") "label": "q", // Label or identifier for this response (e.g., "question", "response A") "coordinates": "https://rc-gate.dataloop.ai/api/v1/items/648992159b8b5e823eda9972/stream", // The response or output value (in this case, another item—possibly a model's generated response) "metadata": { "system": { "automated": true, // Indicates this was generated by a model "promptId": "first" // ID linking back to the original prompt in the file }, "user": { "annotation_type": "prediction", // Annotation represents a model prediction "model": { "confidence": 0.9, // Confidence score of the prediction "name": "model1" // Name of the model that generated the prediction }, "stream": true // Indicates this annotation links to a streamed item (likely the generated output) } }, "creator": "user@dataloop.ai", // Who created or triggered this annotation "createdAt": "2023-06-14T10:10:33.092Z", // Creation time "updatedBy": "user@dataloop.ai", // Last user who updated the annotation "updatedAt": "2023-06-14T10:10:33.092Z", // Last update time "hash": "64885c4d71e85c4f03c3758c_64899218661aa36a1744112c_q_lior@dataloop.ai", // Internal hash ID for annotation tracking "source": "sdk" // Annotation was generated via SDK/API (vs. UI/manual) } ], "annotationsCount": 1, // Total number of annotations for this item "annotated": true // Indicates that the item has at least one annotation } ``` #### 📌 Explanation - This format is used to record model responses, human judgments, or comparative feedback. - The coordinates field in this case holds a link to the output, not geometric data. - Annotations include labels and confidence scores, often tied to a specific promptId. - Suitable for use cases like ranking, binary classification, or scored feedback in RLHF pipelines. --- ## PDF Annotation Output This page describes PDF annotation JSON, a data format for describing PDF data in JavaScript Object Notation (JSON).

It can consist of a single file or multiple files. For instance, a 'Video Item' comprises a sole video file, while a 'Lidar Item' includes multiple PCD frames stitched into one item, presenting them as a sequence. Each DDOE Annotation Studio has its unique item structure. ### PCD Format ``` { "id": "65029ac313c0345fc63a5b5c", "datasetId": "6458d7e0a4aaff79f2f8e16f", "url":

entity within the system. This structure is designed to represent an 'Item' — a core data unit in DDOE's platform — and its associated information for annotation purposes. Here’s a breakdown based on the provided content: #### Type: XYZ XYZ is a tiled web map format that loads map tiles dynamically from a specified URL using the `{z}/{x}/{y}` pattern. It is commonly used for raster-based layers like OpenStreetMap (OSM) and supports zoom levels for smooth navigation. Optional layers (XYZ, OSM, COG) can be added for enhanced visualization. ``` { "shebang": "dataloop", //A fixed identifier indicating that the data structure is in Dataloop's format.

The file contains a list of prompts, and the annotations layer contains a list of responses per prompt. #### File or Prompt Layer Format The following format is a data structure example of a file that contains two prompts. The first prompt contains text and an image, and the second prompt contains text only. ``` { "shebang": "dataloop", "metadata": { "dltype": "prompt" }, "prompts": { "prompt1": [ { "mimetype": "application/text", "value": "What animal is in this image?" }, { "mimetype": "image/jpeg", "value": "https://gate.dataloop.ai/api/v1/items/6489600c8d5a1c350e55116a/stream" } ], "prompt2": [ { "mimetype": "application/text", "value": "What is the eye color of this cat?" } ] } } ```
