Name your Audience Optimization metadata file according to these specifications.
The following syntax defines the structure of a well-formed metadata file name. Note, italics indicates a variable placeholder. The other elements are constants and do not change.
In the name syntax, you'll notice a parent ID variable. Don't confuse it with the parent ID used in the metadata file contents. These 2 variables seem similar, but they represent different things:
Metadata File ID and Categories
In the metadata file name, the parent and child IDs are identifiers that classify the type of data in a file and place it into a hierarchy. You can tag the parent and child elements in file name with the following category IDs:
Let's take a look at how you would use these IDs in a metadata file name. As an example, say your data file consists of campaign creatives. In this case, the campaign is a parent object and the creatives are child objects because they belong to, or are contained by, the campaign. As a result, you'd choose the following IDs for the metadata file name:
Your metadata file name would look like this: 20150827_1_2
Sometimes, you might have data that does not belong to a parent object. Whenever this is the case, select ID 0 for the parent ID. In this case, your file title would look like this: 20150827_0_2.
