Glossary of Terms

The Narrative team knows purchasing and selling data should be easy, so we put together a glossary of commonly used terms to help.

Term

Definition

Acquire Reports A Narrative feature allowing data buyers to have a clear and up to date view of their current and past purchases. This includes data suppliers, amounts purchased, and granular costs. More info here
ADID Advertising ID (Google Play): The advertising ID is a user-resettable, unique, anonymous ID for advertising, provided by Google Play. It gives consumers control over privacy and advertising tracking and provides developers with a simple, standard system to continue to monetize their apps.
API Application Program Interface: An API is a set of programming instructions and standards allowing an app to access a server-based software application or tool. A software company releases its API to the public so that other app and software developers can design products that are powered by its service. Examples include the Facebook Connect API, which allows app developers to utilize the Facebook account system for login.

Blacklist

(Buyer/Seller)

A buyer or seller that is blocked from transacting against an order. Specified by the other seller/buyer.

Blacklist

(User)

A set of user IDs that have been specifically excluded from a campaign, typically because the user does not meet the targeting condition. A blacklist is commonly used to exclude existing users from user acquisition campaigns.
Consumed Resource URI
Also known as App ID or Bundle ID, this is an identifier that defines a particular Application. More info here
CPM Cost Per Thousand: Abbreviated with the Roman numeral M for 1,000, CPM is a campaign more similar to television or print campaigns; the buyer pays one cost for every thousand rows of data.
Data Collection "Data collected" in the Recency Constraint field of an order indicates the time that the event occurred (or the time that the event was recorded by the supplier).
DMP A data management platform is a software platform used for collecting and managing data, mainly for digital marketing purposes. They allow businesses to identify audience segments, which can be used to target specific users and contexts in online advertising campaigns.
Data Discovery Assistant A Narrative feature allowing users to find high-value attributes based on a set of seed data (either a list of apps or a user list). The relationship between the seed data set and the produced attributes is quantified by a normalized pointwise mutual information (PMI) score, which measures the strength of association between two entities.

Device Characteristics Data available for purchase via Narrative’s marketplace that describes the device, but not someone's activity on the device.
Digital Consumption Digital content (apps or websites) associated with an identifier (cookie or mobile ad ID) available for purchase via Narrative’s marketplace.
Data Lake

A centralized repository that allows you to store all your structured and unstructured data at any scale. You can store your data as-is, without having to first structure the data, and run different types of analytics—from dashboards and visualizations to big data processing, real-time analytics, and machine learning to guide better decisions.

Data Point

(aka "attribute," "column," "field")

The smallest possible unit of data that still has meaning to a user of the platform.  Examples of data points include: a user id, a location latitude/longitude, a gender.

Date Range Date Range specifies the lower and upper bound timestamps for observations to be included in an order. In other words, Date Range filters on observation timestamp, not ingestion timestamp.
DAU Daily Active User: The number of active users of an app on a given day. Often reported as an average.
Delivery The transfer of data observations from a buyer (hosted by Narrative) to a seller. Commonly done via Amazon Web Services.
Derived Country Code A field in the data lake containing country information based on lat/lon information or IP address (in that order), if available.
Deterministic Pairs Identifiers describing the same individual as confirmed by Personally identifiable information, or PII, (as opposed to probabilistic pairs, which are less certain).
Direct Deal A buy/sell agreement between one buyer and one seller at a flat fee (monthly, yearly, or just a one time purchase).
Distribute Reports A Narrative feature allowing data sellers to have a clear and up to date view of their current and past transactions. This includes data buyers, amounts purchased, and granular revenue. More info here
DTC Direct to consumer.
eCPM Effective Cost per Thousand: Calculated by dividing total earnings of a publisher by total number of impressions in thousands.
Event A piece of data tied to a specific individual at a specific point in time.
Event Timestamp The date/time at which the data observation occurred (or was collected by the supplier).
Expiration Timestamp The date/time at which a buyer is contractually obligated to purge purchased data based on the licensing terms.
Firehose Defines all of the data from a supplier.
Flight Dates The date range that a buyer wants to buy observations within. For example, if a commercial is airing for the month of June, the flight time is the month of June.
Geofencing
Geofencing uses GPS to create a virtual boundary or radius. Geofencing can be used to send app users offers or messages when they enter a certain range.
Geotargeting
Targeting users based on their current location and sending app messages relevant to where they are.
Hashed Email Hashing is a way of encrypting a piece of data, like an email address, into a hexadecimal string. Each email has its own unique hexadecimal string that remains consistent no matter where the email is used as a login. More info here
IAP In-app purchase: something bought from within an application, typically a mobile app running on a smartphone or other mobile device.
ID Mapping (ID matching) - Using a piece (or pieces) of originally personally identifiable information to link data across multiple sources or channels. An anonymized or hashed email address commonly serves as the match key.
IDFA ID For Advertisers: Created by Apple to replace tracking by UDID, the IDFA is an anonymous tracking identifier (similar to a cookie) that allows developers and marketers to track a user’s activity for advertising purposes. The IDFA is not specific to the user’s hardware, and can be reset if the hardware changes ownership.
Incrementality An ambiguous term similar to "overlap analysis.”
Ingestion The absorption of data from a client into the Narrative data lake, meaning that the data is normalized per the data lake schema and made available in automatic orders. Not to be confused with receipt of files, which means that they are available in a Narrative-hosted S3 bucket.
Ingestion Timestamp When a data observation hits the Narrative data lake.
Latency The time between the event timestamp and the ingestion timestamp. Low latency means an event is ingested and made available in the lake very quickly.

Lookback

(lookback window)

The time elapsed between two separate data events (e.g. Event 1: a user sees an ad, Event 2: the user buys a product - the time between Event 2 and Event 1 is the lookback window).
Mobile Advertising ID (MAID) A unique pseudo-anonymous identifier tied to a mobile phone. iOS and Android have their own unique identifiers
Match Rate The percentage of overlap between two sets of user ID information (usually between a partner's user ID list and a data source, i.e. the Data Lake). It is always better to specify what two ID types need to be matched.
MAU Monthly Active User: A user who has engaged with your app at least once in the last month.
Observation A piece of data describing a specific data instance. May be independent of timestamp (if slow-moving data, e.g. gender).
Onboarding Data Taking data from one source, joining it to other sources so that individuals can be viewed across multiple channels, and pushing the data to other destinations.
Opt-Out
Opting out means a user will take action to withdraw their consent for their data to be collected.
Order A request by a client to buy or sell data. One order is bound by a common business need and may share a set of specifications or requirements, including but not limited to ID type, date range, pricing structure, and country code. One order may contain more than one data type or different specifications, but the main boundary between one order and another is a different client end goal.
Order Approval A Narrative feature launched in 2019 allowing companies with users of different authorization levels to buy data collaboratively. If a company has set up Order Approval, the company's designated partner admins will have the ability to approve or reject orders meeting threshold criteria from standard users.
Order Forecasting A Narrative purchase enablement tool allowing a buyer to estimate the volume of data (unique IDs and total data events).
Overlap Analysis A comparison between two or more data suppliers to gauge the amount of data that is provided by more than one data supplier versus the amount of new data that a supplier offers.
PII Personally identifiable information: Any data that could potentially be used to identify a particular person. Examples include a full name, a home address, a phone number, driver's license number, email address, and more. More info here
POI The definition of Point-of-Interest is a specific physical location which someone may find interesting. Restaurants, retail stores, and grocery stores are all examples of Points-of-Interest.
Programmatic Automated bidding on advertising inventory done by an algorithm or computer program.

Recency

(recency constraint)

The time range between the current day and when a data observation occurred (current day - event timestamp).
SDK Software Development Kit: A SDK or “devkit” is a set of software development tools that help developers create new software. SDKs provide developers with libraries and tools to create, modify, improve or configure the software. While many SDKs contain APIs, they are not identical. SDKs are often available as app platforms.
Sell Offer A sell offer is a collection of business rules that define the data being sold, the commercial terms of the purchase, and who has access to the data. More Info here
Sighting Like "observation," but specific to an individual.
Transaction The batch of data observations pulled and delivered when an active buy order line item is matched to an active sell order.
Transaction Timestamp The time at which a transaction was executed.
UDID Unique Device ID: Historically, each Apple device came with a 40-character Unique Device ID that was used for advertising tracking. UDIDs came from the manufacturer and never changed, even if one person sold their device to another, creating problems for mobile advertisers. Apple now uses an Advertising ID or an IDFA.
Waterfall A term typically used to ambiguously refer to an ordering of preferred suppliers for a data type.
Whitelist (Buyer/Seller) A buyer or seller that is open to transact against an order. Specified by the other seller/buyer.
Whitelist (User)  In mobile advertising, a whitelist is a database of mobile device IDs that are the target of a mobile advertising campaign. Whitelists are commonly used in re-engagement campaigns. Whitelists are also used by advertising exchange platforms – whitelisted sources include publishers and networks that a marketer has chosen to run their advertisements on.
