A media representative can offer a placement within an authorized property while a similar property falls outside its scope. IAB Tech Lab describes ads.txt as a way for publishers to declare authorized digital sellers. An original sample can test whether a model attributes authorization to the correct property and seller. IAB Tech Lab authorized digital sellers
Invent two media properties and a representative agreement for one. Build a mock digital seller entry whose domain matches but account reference differs in one case. Ask the model which representation is supported and what evidence is missing. Score seller, property and effective period independently.
Use fake domains and original records. Keep actual publisher agreements, ad account identifiers, bids and campaign details out. Clear commercial use rights before adding any third-party evidence.
Describe a fictional media representation sample
Original Fiund exercise
A seller entry must match the property, account and representation term
Two fake media properties on example.test have original representation records and inert seller IDs. No publisher agreement, real ad account, bid or campaign information appears.
| Record | Source | What it records |
|---|---|---|
| MR1 | Practice representation agreement | Property A authorizes representative S, account AC1, during days 1–10. Property B not covered. |
| MR2 | Mock A seller entries | Entry E1 names S/AC1 on A. Entry E2 names same S domain but account AC2; no AC2 amendment supplied. |
| MR3 | B and date check | B has an S/AC1-style listing but no B representation agreement. Requested date day 5. |
Question for the model
Which entry matches the supplied day-5 representation scope, and do a shared seller domain or account extend it to E2 or B?
Show the reference answer and checks
MR1 and MR2 support E1's Property A, S and AC1 match within the day-5 term. E2 changes the account to AC2 without an amendment, leaving a mismatch despite the shared seller domain. MR3's B listing lacks B-specific representation authority. Preserve property, seller, account and dates rather than treating a domain or reused account pattern as a blanket authorization across inventory.
- Matching seller domains while ignoring differing account references.
- Extending one property's representation agreement to another property with a similar listing.
Fields to preserve
- Property and representative
- Defines the inventory scope.
- Seller account reference
- Disambiguates entries under one domain.
- Effective period and amendment
- Limits the stated authority in time.
Test another case
Ask about day 12 without renewal evidence. Require the earlier exact E1 match to be qualified by its expired term.
Use fake domains and original documents. Exclude publisher contracts, real IDs, bids and campaign records.
