Template:iOS Configure Metadata

Configure Metadata

All the SDK methods handles only two types of objects: NSString, NSDictionary. The parameters passed must be either a JSON formatted string or a NSDictionary object. The JSON passed in the SDK must be well-formed.

• NSDictionary object
  • If an object of unexpected type is passed to the method, the error message will be logged.
  • If string has invalid JSON format, the error message will be logged.
• JSON value must be string value.
  • This includes boolean and numeric values. For example, a value of true should be represented with "true", number value 123 should be "123".
  • All the Nielsen Key names (e.g. appid, program) are case-sensitive. Use the correct variable name as specified in the documentation.
• JSON string can be prepared using either raw NSString or serialized NSDictionary.

Examples regarding usage of segments within SDK:

• All comedy clips and stories for a Brand rolled into a "Comedy" segment
• genre grouping content by Comedy vs. Drama
• group related Text + Video content - i.e. for a show that has a lot of - static pages associated with it
• packaging based on how clients sell inventory
• grouping related types of content either by genre, category or platform.

Metadata Example

Swift

let contentMetadata = [
    "type": "content",
    "assetid": "C77664",
    "program": "The Big Bang Theory",
    "title": "The Pants Alternative S03E18",  //Formats accepted: S01E03, S1E3, S1 E3

    "isfullepisode": "Yes",
    "adloadtype": "2",
    "segB": "CustomSegmentValueB", //optional
    "segC": "CustomSegmentValueC" //optional

];

Objective-C

 
NSDictionary * contentMetadata = @ {
    @ "type": @ "content",
    @ "assetid": @ "C77664",
    @ "program": @ "The Big Bang Theory",
    @ "title": @ "The Pants Alternative S03E18", //Formats accepted: S01E03, S1E3, S1 E3

    @ "length": @ "3600",
    @ "airdate": @ "2022-03-21T10:05:00",
    @ "isfullepisode": @ "y",  
    @ "adloadtype": @ "2",
    @ "segB": @ "CustomSegmentValueB", //optional
    @ "segC": @ "CustomSegmentValueC" //optional

}

Ad Metadata

The Ad Metadata (if applicable) should be passed for each individual ad.

Keys	Description	Values	Required
type	type of Ad	'preroll', 'midroll', 'postroll' 'ad' - If specific type can not be identified.	✓
assetid	unique ID assigned to Ad	custom (no Special Characters)	✓

Example Ad Object

// create Ad object
"ad": {
  "type": "preroll",
  "assetid": "AD-ID123"
}

Configure Static Metadata if Applicable

The below is to measure Static Content.

The Nielsen reserved keys are:

Key	Description	Data Type	Value	Required?
type	asset type	fixed	'static'	Yes
section	section of each site (e.g. section value should be first level in page URL: website.com/section). Limit to 25 unique values	dynamic	custom (no Special Characters)	Yes
segA	custom segment for reporting: Limit to 25 unique values across custom segments (segA + segB + segC)	dynamic	custom	No
segB	custom segment for reporting: Limit to 25 unique values across custom segments (segA + segB + segC)	dynamic	custom	No
segC	custom segment for reporting: Limit to 25 unique values across custom segments (segA + segB + segC)	dynamic	custom	No

The values passed through the Nielsen keys will determine the breakouts that are seen in reporting. The custom segments (A, B & C) will roll into the sub-brand. To not use custom segments A, B and C, do not pass any value in these keys.

Aggregation Limits There are limits on the number of unique values that can be aggregated on in reporting. The specific limitations by key are:

Key	Aggregation Limit
section	maximum of 25 unique values (section <= 25)
segA	Maximum number of unique values allowed across segA, segB, and segC is 25 (segA + segB + segC<= 25)
segB	Maximum number of unique values allowed across segA, segB, and segC is 25 (segA + segB + segC<= 25)
segC	Maximum number of unique values allowed across segA, segB, and segC is 25 (segA + segB + segC<= 25)

Example Static Object

        let staticData =
            [
                "type": "static",
                "section": "Section Name",
                "segA": "segmentA",
                "segB": "segmentB",
