title: Dataset Versions
|
||
---
|
||
|
||
Use the Dataset versioning WebApp (UI) features for viewing, creating, modifying, and
|
||
deleting [Dataset versions](../dataset.md#dataset-versioning).
|
||
|
||
|
||
|
||
|
||
## Dataset Version History
|
||
The WebApp (UI) presents your dataset version structure in tree view <img src="/docs/latest/icons/ico-tree-view.svg" alt="Tree view" className="icon size-md space-sm" />
|
||
or list view <img src="/docs/latest/icons/ico-list-view.svg" alt="List view" className="icon size-md space-sm" />.
|
||
|
||
The tree view shows the lineage of the dataset's versions.
|
||
|
||
<div class="max-w-50">
|
||
|
||
|
||
|
||
|
||
</div>
|
||
|
||
The list view lists the dataset's versions chronologically by last update time.
|
||
|
||
<div class="max-w-50">
|
||
|
||
|
||
|
||
|
||
</div>
|
||
|
||
Click <img src="/docs/latest/icons/ico-sort.svg" alt="Sort order" className="icon size-md space-sm" /> to order the
|
||
dataset versions in ascending or descending order based on their last update time.
|
||
|
||
Use the search bar to find specific versions. You can query by version name, version description, or version ID. The search returns
|
||
all versions that match the query.
|
||
|
||
In tree view, parent versions that do not match the query where a child version does appear in a muted color.
|
||
|
||
<div class="max-w-50">
|
||
|
||
|
||
|
||
|
||
</div>
|
||
|
||
### Version Actions
|
||
|
||
Access dataset version actions, by right-clicking a version, or through the menu button <img src="/docs/latest/icons/ico-dots-v-menu.svg" alt="Dot menu" className="icon size-md space-sm" /> (available on hover).
|
||
|
||
* **Rename** - Change the version's name
|
||
* **Create New Version** - Creates a child version of a *Published* dataset version. The new version is created in a *draft*
|
||
state, and inherits all the parent version's frames
|
||
* **Delete** - Delete the version. Only *Draft* versions can be deleted.
|
||
* **Publish** - Make a *Draft* version read-only to preserve its contents.
|
||
|
||
:::tip Publishing versions
|
||
When publishing a version, you can create an additional working copy. The new version is created in a *draft* state, and
|
||
inherits all the published version's frames.
|
||
|
||
<div class="max-w-75">
|
||

|
||
|
||
## Version Data
|
||
A selected dataset version's information and contents are presented on the main section of the page, to the right of
|
||
the dataset's version list.
|
||
|
||
The version information is presented in the following tabs:
|
||
* [Frames](#frames)
|
||
* [Statistics](#statistics)
|
||
* [Metadata](#metadata)
|
||
* [Info](#info)
|
||
|
||
## Frames
|
||
The **Frames** tab displays the contents of the selected dataset version.
|
||
|
||
View the version's frames as thumbnail previews or in a table. Use the view toggle to switch between thumbnail
|
||
view <img src="/docs/latest/icons/ico-grid-view.svg" alt="thumbnail view" className="icon size-md space-sm" /> and
|
||
table view <img src="/docs/latest/icons/ico-table-view.svg" alt="table view" className="icon size-md space-sm" />.
|
||
|
||
Use the thumbnail view for a visual preview of the version's frames. You can increase <img src="/docs/latest/icons/ico-zoom-in.svg" alt="Zoom in" className="icon size-md space-sm" />
|
||
and decrease <img src="/docs/latest/icons/ico-zoom-out.svg" alt="Zoom out" className="icon size-md space-sm" /> the size of
|
||
the previews.
|
||
|
||
|
||
|
||
|
||
Use the table view to list the version's frames in a customizable table. Click <img src="/docs/latest/icons/ico-settings.svg" alt="Setting Gear" className="icon size-md" />
|
||
for column customization options.
|
||
|
||
|
||
|
||
|
||
The dataset version's frames can be filtered by multiple criteria. The resulting frames can be [exported as a JSON file](#exporting-frames).
|
||
|
||
To view the details of a specific frame, click on its preview, which will open the [Frame Viewer](webapp_datasets_frames.md#frame-viewer).
|
||
|
||
### Simple Frame Filtering
|
||
Simple frame filtering returns frames containing at least one annotation with a specified label.
|
||
|
||
**To apply a simple frame filter,** select a label from the **LABEL FILTER** list.
|
||
|
||
<Collapsible type="screenshot" title="Simple filter example">
|
||
|
||
* The **FRAMES** tab in the image below contains 101 frames.
|
||
|
||
|
||
|
||
|
||
|
||
* A simple label filter for `teddy bear` shows three frames, each containing at least one ROI labeled `teddy bear`.
|
||
|
||
|
||
|
||
|
||
</Collapsible>
|
||
|
||
### Advanced Frame Filtering
|
||
|
||
Alternatively, a combination of ROI, frame, and source rules can be specified to apply more elaborate and specific
|
||
filters.
|
||
|
||
**To apply advanced filters:**
|
||
1. In the **FRAMES** tab, click <img src="/docs/latest/icons/ico-advanced-filters.svg" alt="Advanced filters" className="icon size-md space-sm" /> (**Advanced filters**).
|
||
1. In a **FRAME FILTER**, create one of the following rules:
|
||
* ROI rule - Use "Include" and "Exclude" conditions to match frames according to ROI label. If the "Include"
|
||
condition is used, frames match the rule if they contain at least one annotation object (ROI) with ALL labels in the
|
||
rule. If the "Exclude" condition is used, frames match the rule if NONE of their ROIs contain the label. Multiple ROI
|
||
rules in the same filter are evaluated independently against all frame ROIs. Meaning, a frame will match the filter
|
||
if it contains at least one annotation matching each rule, even if the annotations are in different ROIs. Click <img src="/docs/latest/icons/ico-code.svg" alt="Lucene query mode" className="icon size-md space-sm" />
|
||
to explicitly specify your rule with Lucene
|
||
* Frame rule - Query frame metadata. Enter a Lucene query of frame metadata fields in the format `meta.<key>:<value>`
|
||
(can use AND, OR, and NOT operators).
|
||
* Source rule - Query frame source information. Enter a Lucene query of frame metadata fields in the format
|
||
`sources.<key>:<value>` (can use AND, OR, and NOT operators).
|
||
|
||
A frame filter can contain a number of rules. For each frame filter, the rules are applied with a logical AND operator. For example, the dataset version in the image below has one filter. “Frame Filter 1” has two rules:
|
||
1. ROI rule - the frame must include an ROI with the `cat` label
|
||
2. Source rule - the frames must be 640 pixels wide.
|
||
|
||
The returned frames are those that match the first rule AND the second rule within the frame filter.
|
||
|
||
|
||
|
||
|
||
Create additional frame filters by clicking <img src="/docs/latest/icons/ico-add.svg" alt="Add new" className="icon size-md space-sm" />.
|
||
Multiple frame filters are applied with a logical OR operator.
|
||
|
||
For example, the dataset version in the image below has two frame filters. "Frame Filter 1" has the same two rules
|
||
described in the example above. "Frame Filter 2" specifies an ROI rule for the frame to contain an ROI with the label
|
||
`dog`. So the frames returned are those that match ALL of Frame Filter 1's rules OR ALL of Frame Filter 2's rules.
|
||
|
||
|
||
|
||
|
||
To clear all filters click <img src="/docs/latest/icons/ico-filter-reset.svg" alt="Clear filters" className="icon size-md" />.
|
||
|
||
|
||
#### Filtering Examples
|
||
|
||
<Collapsible type="screenshot" title="ROI Rules">
|
||
|
||
* Create one ROI rule for the `teddy bear` label, which shows the same three frames as the simple frame filter (above).
|
||
|
||
|
||
|
||
|
||
* In the ROI rule, add a second label. Add `partially_occluded`. Only frames containing at least one ROI labeled as both
|
||
`teddy bear` and `partially_occluded` match the filter.
|
||
|
||
|
||
|
||
|
||
* By opening a frame in the frame viewer, you can see an ROI labeled with both.
|
||
|
||
|
||
|
||
|
||
* To find frames that contain multiple ROIs, each with a different label, use separate ROI rules. Create an ROI rule for
|
||
the `teddy bear` label and, in the same filter, add another ROI rule for the `person` label. This will return all
|
||
frames that include at least one ROIs with a `person` label AND at least one (other) ROI with a `teddy bear` label.
|
||
|
||
|
||
|
||
|
||
* You can also exclude certain ROI labels. Create an ROI rule to include `teddy bear` and, in the same filter, an ROI
|
||
rule to exclude `person`. This will return all frames that include at least one ROI with the label `teddy bear` AND have
|
||
NO ROI with the `person` label

Filter by metadata using Lucene queries.
|
||
|
||
* Add a frame rule to filter by the metadata key `dangerous` for the value of `yes`.
|
||
|
||
|
||
|
||
|
||
* Open a frame in the frame viewer to see its metadata.

|
||
### Sorting Frames
|
||
|
||
Sort the dataset version’s frames by any of the following attributes:
|
||
* ID
|
||
* Last update time
|
||
* Dimensions (height)
|
||
* Timestamp
|
||
* Context ID
|
||
* Metadata key - Click `+ Metadata Key` and select the desired key for sorting
|
||
|
||
Click <img src="/docs/latest/icons/ico-sort.svg" alt="Sort order" className="icon size-md space-sm" /> to toggle between ascending and descending sort orders.
|
||
|
||
|
||
|
||
|
||
### Exporting Frames
|
||
|
||
To export (download) the filtered frames as a JSON file, click <img src="/docs/latest/icons/ico-bars-menu.svg" alt="Menu" className="icon size-md space-sm" /> > **EXPORT FRAMES**.
|
||
|
||
### Frame Browser Configuration
|
||
Click <img src="/docs/latest/icons/ico-bars-menu.svg" alt="Menu" className="icon size-md space-sm" /> to open the
|
||
frame browser configuration settings.

|
||
|
||
#### Grouping Previews
|
||
|
||
Use the **Grouping** menu to set how to display frames that share a common property:
|
||
* **Split Preview** - Show a separate preview for each individual FrameGroup
|
||
* **Group by URL** - Show a single preview for all FrameGroups with the same context ID. For example, users can set the
|
||
same `context_id` to multiple FrameGroups that represent frames in a single video.
|
||
* **Sample by Property** - Specify a frame or ROI property whose value to group frames by and set the number of frames
|
||
to preview for each group. For example, in the image below, frames are grouped by ROI labels. Each group displays five
|
||
samples of frames that contain an ROI with the same label.
|
||
|
||
|
||
|
||
|
||
**To sample by property:**
|
||
1. In the **Grouping** menu, click **Sample by Property**
|
||
1. In the **Sample by Property** modal, input the following:
|
||
* Select the Property type:
|
||
* ROI - Properties associated with the frame ROIs (e.g. ROI label names, IDs, confidence, etc.)
|
||
* Frame - Properties associated with the frames (e.g. update time, metadata, timestamp, etc.)
|
||
* Property name - Property whose value to group the frames by
|
||
* Sample size - Number of frames to preview for each group
|
||
* ROI match query (*For grouping by ROI property only*) - A Lucene query to filter which of a frame's ROIs
|
||
to use in grouping by their properties. For example, in a Hyper-Dataset where ROIs have object labels and type labels,
|
||
view a sample of frames with different types of the same object by grouping frames according to `label.keyword`
|
||
with a match query for the object of interest.
|
||
<br/>
|
||
<div class="max-w-50">
|
||
|
||
|
||
|
||
|
||
</div>
|
||
|
||
The image below shows a sample of 3 frames which have ROIs of each type (`pedestrian`, `rider`, `sitting`) of `person`.
|
||
|
||
|
||
|
||
:::note Property N/A group
|
||
If there are frames which have no value for the grouped by property, a sample of them will be provided as a final
|
||
group. If you sample according to an ROI property, this group will NOT include frames that have no ROIS at all.
|
||
:::
|
||
1. Click **Save**
|
||
|
||
Once saved, whenever you select the **Sample by Property** option in the **Grouping** menu, the frame will be grouped
|
||
according to the previously configured setting.
|
||
|
||
**To modify the grouping property:**
|
||
1. Hover over **Sample by Property**
|
||
1. Click <img src="/docs/latest/icons/ico-edit.svg" alt="Edit pencil" className="icon size-md space-sm" />
|
||
1. Modify the **Sample by Property** configuration
|
||
1. Click **Save**
|
||
|
||
|
||
|
||
#### Preview Source
|
||
When using multi-source FrameGroups, users can choose which of the FrameGroups' sources will be displayed as the preview.
|
||
|
||
Select a source from the **Current Source** menu.
|
||
Choose the `Default preview source` option to present the first available source for each frame (sources are retrieved in ASCIIbetical order).
|
||
|
||
Choose the `All sources` option to present all the FrameGroup’s sources in a grid. In this view, the annotation panel
|
||
shows annotations grouped by their respective sources. Additionally, annotation tools (e.g. create/delete/modify
|
||
annotations) are not available in this view.
|
||
|
||
|
||
|
||
|
||
:::note Unavailable Source
|
||
If a FrameGroup doesn't have the selected preview source, the preview displays the "Source not available" message.
|
||
:::
|
||
|
||
## Statistics
|
||
|
||
The **Statistics** tab allows exploring frame and ROI property distribution across a Hyper-Dataset version:
|
||
1. Query the frames to include in the statistics calculations under **Filter by label**. Use [simple](#simple-frame-filtering)
|
||
or [advanced](#advanced-frame-filtering) frame filters. If no filter is applied, all frames in the dataset version will
|
||
be included in the calculation.
|
||
1. Select the property whose distribution should be calculated
|
||
* Select the property **Type**:
|
||
* **ROI** - Frame ROI properties (e.g. ROI label, ID, confidence, etc.). This will calculate the distribution of
|
||
the specified property across all ROIs in the version's frames.
|
||
* **Frame** - Frames properties (e.g. update time, metadata keys, timestamp, etc.)
|
||
* Input the **Property** key (e.g. `meta.location`)
|
||
* If **ROI** property was selected, you can also limit the scope of ROIs included in the calculation with the
|
||
**Count ROIs matching** filter: Input a Lucene query to specify which ROIs to count
|
||
1. Click **Apply** to calculate the statistics
|
||
|
||
For example, calculating the distribution for the `label` ROI property, specifying `rois.confidence: 1` for ROI matching
|
||
will show the label distribution across only ROIs with a confidence level of 1.
|
||
|
||
|
||
|
||
|
||
By default, the ROI label distribution across the entire Hyper-Dataset version is shown.
|
||
The tab displays the following information
|
||
* Object counts:
|
||
* Number of annotations matching specification
|
||
* Number of annotated frames in the current frame filter selection
|
||
* Total number of frames in the current frame filter selection
|
||
* Each property is listed along with its number of occurrences in the current frame filter selection
|
||
* The pie chart visualizes this distribution. Hover over a chart segment and its associated property and count will
|
||
appear in a tooltip and its usage percentage will appear at the center of the chart.
|
||
|
||
|
||
|
||
|
||
## Metadata
|
||
The **Metadata** tab presents any additional metadata that has been attached to the dataset version.
|
||
|
||
**To edit a version's metadata,**
|
||
|
||
1. Hover over the metadata box and click **EDIT**
|
||
1. Edit the section contents (JSON format)
|
||
1. Click **OK**
|
||
|
||
|
||
|
||
|
||
## Info
|
||
|
||
The **Info** tab presents a version's general information:
|
||
* Version ID
|
||
* Version name
|
||
* Dataset ID
|
||
* Dataset name
|
||
* Dataset description
|
||
* Dataset tags
|
