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 list view <img src="/docs/latest/icons/ico-list-view.svg" alt="List view" className="icon size-md space-sm" />
|
||
or tree view <img src="/docs/latest/icons/ico-tree-view.svg" alt="Tree view" className="icon size-md space-sm" />.
|
||
|
||
The list view lists the dataset's versions chronologically by last update time.
|
||
|
||
|
||
|
||
The tree view shows the lineage of the dataset's versions.
|
||
|
||
|
||
|
||
Use the search bar to find specific versions. You can query by version name or version description. 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.
|
||
|
||
|
||
|
||
### 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.
|
||
|
||
## 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.
|
||
|
||
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.
|
||
|
||
<details className="cml-expansion-panel screenshot">
|
||
<summary className="cml-expansion-panel-summary">Simple filter example</summary>
|
||
<div className="cml-expansion-panel-content">
|
||
|
||
* 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`.
|
||
|
||
|
||
|
||
</div>
|
||
</details>
|
||
|
||
### 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 **Advanced filters**.
|
||
1. In a **FRAME FILTER**, create one of the following rules:
|
||
* ROI rule - Use "Include" and "Exclude" conditions to match frames by ROI label; frames match the rule when
|
||
containing at least one annotation object (ROI) with **all** labels in the rule. 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
|
||
|
||
<details className="cml-expansion-panel screenshot">
|
||
<summary className="cml-expansion-panel-summary">ROI Rules</summary>
|
||
<div className="cml-expansion-panel-content">
|
||
|
||
* 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.
|
||
|
||

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.
|
||
|

||
|
||
Filter by sources using Lucene queries.
|
||
|
||
* Add a source rule to filter for sources URIs with wildcards.
|
||
|
||
|
||
|
||
Lucene queries can also be used in ROI label filters and frame rules.
|
||
|
||
</div>
|
||
</details>
|
||
|
||
### 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
|
||
FrameGroups or SingleFrames can share the same `context_id` (URL). For example, users can set the same `context_id`
|
||
to multiple FrameGroups that represent frames in a single video.
|
||
|
||
Use the **Grouping** menu to select one of the following options:
|
||
* Split Preview - Show separate previews for each individual FrameGroup, regardless of shared context.
|
||
* Group by URL - Show a single preview for all FrameGroups with the same context
|
||
|
||
#### 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 **PREVIEW SOURCE** menu.
|
||
Choose the `Default preview source` option to present the first available source.
|
||
|
||
:::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 displays a dataset version's label usage stats.
|
||
* Each label is listed along with the number of times it was used in the version
|
||
* The pie chart visualizes these stats. Hover over a chart slice and its associated label and usage
|
||
percentage will appear at the center of the chart.
|
||
|
||
|
||
|
||
## Metadata
