#ItemDescription

Extraction pattern - techWhat is the tech for the extraction pattern? map/reduce, optimized for scale, GraphQL or others?

How to assert data integrityHow to assert data integrity? A checksum after record is locked & written to the chain, store the acknowledgement from the HLF to a control DB and map it to a record set etc.

How to assert data qualityHow to run technical and business validation on data and certify the data?

Data quality error threshold

Current practice allows for an error rate of up to 5%. Allow? If allowed, how to design & implement


Reference data validationWhere to host reference data service? Within member's enterprise or within node? Must be applied before extraction (tenet) 

Reference data lookup services/APIsWhich APIs to look up? For example, USPS state/zip validation, Carfax etc.

Reference data lookup services/APIs - pricing modelWho pays (assumption - whoever owns the data pays), and how to charge the consumers (via assigned accounts, via centralized billing account prorated to consumption etc.). Who signs the vendor contracts

Separating the Hyperledger Fabric Network from the data accessCan a carrier participate in the network from a hosted node without putting the data there?  That is, can we give a carrier access to the network without them having the data access portion hosted in the same node.  The HLF runtimes are not required to run in the carrier, and only a simple api is made available for extraction.

Simplify the technical footprintCan we simplify the architecture so that there are not so many technologies required?

Hosted nodesShould we consider hosted nodes for the HLF network instead of requiring all carriers who desire data privacy to host the network?
