The metadata received for each asset is used for classification and reporting. There are reserved Nielsen keys for collecting the required metadata.

Reserved Keys

Content and Ad Metadata can be passed through key-values using the Nielsen reserved keys. The last column in the table below indicates metadata parameters that will be displayed in reporting.

Content Metadata

Key Description Values Required for Audio/Video? Required for Static (page)? Reported for
clientid Brand value is automatically populated through the App ID provided. The value passed here will override the default value. (e.g. Multiple brands in App) custom Optional Optional Audio / Video and Static Measurement
subbrand VCID value is automatically populated through the App ID provided. This value passed here will override the default value. (e.g. Multiple Sub-brands in App) custom Optional Optional Audio / Video and Static Measurement

  • audio / video – "content"
  • page – "static"
  • ad – "preroll", "midroll" or "postroll"

clientid & subbrand (vcid) By default, clientid and subbrand are setup in Nielsen backend configuration to capture brand and sub-brand information. The fields get populated from backend for a registered client appid. But if an app contains multiple brands and sub-brands and client is willing to give credit to another brand or sub-brand then :

  • Client app developer can override the clientid and subbrand (brand and sub-brand info.) in loadMetadata call to get a proper measurement for a desired brand and sub-brand.
    • If no clientid and subbrand are specified in CMS of a content and an ad, default values reported in the Configuration will be reported.
    • If clientid and subbrand are specified in CMS of the content or ad, the most recent clientid and subbrand will be reported in subsequent pings. To report with a different clientid and subbrand, include the new values for the keys in their subsequent loadMetadata call.

Picture-in-picture (PIP) mode Once the app detects PIP mode, call loadMetadata with the same set of assetids, values and with one additional parameter "pipmode": "true". Once PIP mode is disabled in the device, call loadMetadata again with "pipmode":"false".

Custom Variables Extension

Contact Nielsen Technical Account Manager (TAM) to configure any custom variables, as needed for implementing the application.

See Custom Variables Extension for more information.

Key Description Values Required for Audio / Video? Required for Static (page)
type Type of ad "preroll"

"midroll" "postroll"

Mandatory Not Required
assetid An ID assigned to the advertisement. Can be an internal ID, an ID provided by the ad server, or a randomly generated ID. Must be unique across all ads custom Mandatory Not Required
title Title of the advertisement "MyAdName" Mandatory Not Required

Passing Metadata

The required metadata can be passed as key values through the loadMetadata method. The sample code below shows a metadata objects for various assets. Audio / Video Measurement Asset Type should be "content"

    {
       "type": "content",
       "assetName": "myassetName",
       "length": "300.0",
       "title": "myTitle",
       "program": "myProgram",
       "censuscategory": "myCensusCategory",
       "assetid": "myAssetId",
       "channelName": "myChannel",
       "adloadtype": "2",
       "segB": "segmentB",
       "segC": "segmentC",
       "isfullepisode":"y",
       "crossId1": "Reference11",
       "crossId2": "Reference22",
       "airdate": "20161013 20:00:00"
    }

Static (Page) Measurement Asset Type should be "static"

    {
       "type": "static",
       "assetid": "static123",
       "assetName": "Page-Asset",
       "section": "siteSection",
       "segA": "segmentA",
       "segB": "segmentB",
       "segC": "segmentC"
    }

For any of the ad types

    {
        "type": "midroll",
        "length": "30.0",
        "assetid": "myMidrollAssetId",
        "adloadtype": "2",
        "tv": "true",
        "dataSrc": "cms"
    }

Note: In case the individual ad details are not available, send ad pod (presence) details through the loadMetadata and playhead position through setPlayheadPosition.

loadMetadata The object can then be passed when calling loadMetadata.

    loadMetadata(jsonMetadataObject);
