The context property is an array of strings that determines what the Web SDK can automatically collect. While this data can provide great value, omitting some of this data can be beneficial so that you can comply with your organization’s privacy policy.

Context keywords and XDM elements

If you include a given context keyword, the Web SDK automatically populates all of its associated XDM elements. If you want to omit a specific XDM element while allowing others, you can clear values out using onBeforeEventSend. If you send multiple events on a page, the Web SDK includes these fields on every SendEvent call.

Web

The "web" keyword collects information about the current page.

Dimension
Description
XDM path
Example value
Page URL
The URL of the current page.
xdm.web.webPageDetails.URL
https://example.com/index.html
Referrer URL
The URL of the previous page visited.
xdm.web.webReferrer.URL
http://example.org/linkedpage.html

Device

The "device" keyword collects information about the user’s device.

Dimension
Description
XDM path
Example value
Screen height
The height of the screen in pixels.
xdm.device.screenHeight
900
Screen width
The width of the screen in pixels.
xdm.device.screenWidth
1440
Screen orientation
The orientation of the screen.
xdm.device.screenOrientation
landscape or portrait

Environment

The "environment" keyword collects information about the user’s browser.

Dimension
Description
XDM path
Example value
Environment type
The type of environment through which the experience surfaced. The Web SDK always sets this field to browser.
xdm.environment.type
browser
Viewport height
The height of the browser’s content area in pixels.
xdm.environment.browserDetails.viewportHeight
679
Viewport width
The width of the browser’s content area in pixels.
xdm.environment.browserDetails.viewportWidth
642

Place context

The "placeContext" keyword collects information about the user’s location.

Dimension
Description
XDM path
Example value
Local time
Local timestamp for the end user in simplified extended ISO 8601 format.
xdm.placeContext.localTime
YYYY-08-07T15:47:17.129-07:00
Local timezone offset
The number of minutes that the user is offset from GMT.
xdm.placeContext.localTimezoneOffset
360
Country code
The country code of the end user.
xdm.placeContext.geo.countryCode
US
State province
The state province code of the end user.
xdm.placeContext.geo.stateProvince
CA
Latitude
The latitude of the end user location.
xdm.placeContext.geo._schema.latitude
37.3307447
Longitude
The longitude of the end user location.
xdm.placeContext.geo._schema.longitude
-121.8945965

Timestamp

The timestamp keyword collects information about the timestamp of the event. This part of context cannot be removed.

Dimension
Description
XDM path
Example value
Timestamp of the event
UTC timestamp for the end user in simplified extended ISO 8601 format.
xdm.timestamp
2019-08-07T22:47:17.129Z

Implementation details

The implementationDetails keyword collects information about the SDK version used to collect the event.

Dimension
Description
XDM path
Example value
Name
The software development kit (SDK) identifier. This field uses a URI to improve uniqueness among identifiers provided by different software libraries.
xdm.implementationDetails.name
When the standalone library is used, the value is https://ns.adobe.com/experience/alloy. When the library is used as part of the tag extension, the value is https://ns.adobe.com/experience/alloy+reactor.
Version
The software development kit (SDK) version.
xdm.implementationDetails.version
When the standalone library is used, the value is the library version. When the library is used as part of the tag extension, the value is the library version and the tag extension version joined with a +. For example, if the library version is 2.1.0 and the tag extension version is 2.1.3, the value would be 2.1.0+2.1.3.
Environment
The environment where the data was collected. This is always set to browser.
xdm.implementationDetails.environment
browser

High entropy client hints

The "highEntropyUserAgentHints" keyword collects detailed information about the user’s device. This data is included in the HTTP header of the request sent to Adobe. After the data has arrived within the Edge network, the XDM object populates its respective XDM path. If you set the respective XDM path in your sendEvent call, it takes precedence over the HTTP header value.

If you use device lookups when configuring your datastream, data can be cleared out in favor of device lookup values. Some client hint fields and device lookup fields cannot exist in the same hit.

Dimension
Description
HTTP header
XDM path
Example value
Operating system version
The version of the operating system.
Sec-CH-UA-Platform-Version
xdm.environment.browserDetails.
userAgentClientHints.platformVersion
Architecture
The underlying CPU architecture.
Sec-CH-UA-Arch
xdm.environment.browserDetails.
userAgentClientHints.architecture
Device model
The name of the device used.
Sec-CH-UA-Model
xdm.environment.browserDetails.
userAgentClientHints.model
Bitness
The number of bits that the underlying CPU architecture supports.
Sec-CH-UA-Bitness
xdm.environment.browserDetails.
userAgentClientHints.bitness
Browser vendor
The company that created the browser. The low entropy hint Sec-CH-UA also collects this element.
Sec-CH-UA-Full-Version-List
Browser name
The browser used. The low entropy hint Sec-CH-UA also collects this element.
Sec-UA-Full-Version-List
xdm.environment.browserDetails.
userAgentClientHints.brand
Browser version
The significant version of the browser. The low entropy hint Sec-CH-UA also collects this element. Exact browser version is not automatically collected.
Sec-UA-Full-Version-List
xdm.environment.browserDetails.
userAgentClientHints.version

Collect context information using the Web SDK tag extension

The context information setting is a combination of radio buttons and check boxes when configuring the tag extension. Each checkbox maps to a context keyword.

  1. Log in to experience.adobe.com using your Adobe ID credentials.
  2. Navigate to Data Collection > Tags.
  3. Select the desired tag property.
  4. Navigate to Extensions, then click Configure on the Adobe Experience Platform Web SDK card.
  5. Scroll down to the Data Collection section, then select either All default context information or Specific context information.
  6. If you select Specific context information, enable the check box next to each desired context information element.
  7. Click Save, then publish your changes.

Collect context information using the Web SDK JavaScript library

Set the context array of strings when running the configure command. If you omit this property when configuring the SDK, all context information except "highEntropyUserAgentHints" is collected by default. Set this property if you want to collect high entropy client hints, or if you want to omit other context information from data collection. Strings can be included in any order.

NOTE
If you want to collect all context information, including high entropy client hints, you must include every value in the context array string. The default context value omits highEntropyUserAgentHints, and if you set the context property, any omitted values do not collect data.
