Enabling value enhancement of reference data by employing scalable cleansing and evolutionarily tracked source data tags
Provision for scalable cleansing and value enhancement of data in the context of a multi-source multi-tenant data repository. The source data comes from multiple sources and on multiple topics. Evolutionarily tracked source data tags are used to hold tracking information reflecting the nature and sources of each change to the data, as it is affected during the various stages of data processing. The stages of processing include validation, normalization, single-source cleansing and cross-source processes. Various rules are applied during these stages, and evolutionarily tracked source data tags are used to record sources and agents of all changes to the data. As information is processed, transformed, and added to the repository, corresponding evolutionarily tracked source data tags are stored in association with the various information elements. The information contained in these tags can be used to enforce data entitlements in a multi-tenant data repository environment.

Merchant data cleansing in clearing record
A network operator intermediates a cashless transaction by sending a payment device issuer an outbound clearing data file enriched with cleansed merchant data. Issuers that choose to participate in the merchant data cleansing service will be provided with the cleansed, and optionally augmented, merchant information. Providing this data to the issuer could be used to help reduce costs associated with “do not recognize” calls by cardholders, disputed charges, and charge-backs. With cleansed data provided in the clearing record, a device holder would be given access to this cleansed information about the merchant where a transaction took place through their statement. The present disclosure also provides for augmenting the clearing record data to include merchant-specific add-on and / or aggregate data not presently included in the transaction clearing record, yet useful to the issuer both in form and content.
