SUBJECT	User Authentication for Application Access
STATUS	Open
DECISION	User Authentication is Platform Specific or can it use Okta
DISCUSSION	The authentication of users must be cloud specific for access to applications because there is no generic authentication provider. - start with aws strategy - cognito - want to offload identiy to identity provider - can we use okta as the main identity management and link it to the underlying provider thus acting as a common api for the applications?

SUBJECT	DA - Harmonized Data Store
STATUS	Proposed
DECISION	Proposal: HDS can be persistent or transient. It's a member's decision. See next HDS can be persistent and can be used by member's as a "warehouse on the edge" for sharing data via openIDL
DISCUSSION	The data available for extraction must be normalized for multiple extractions across multiple use cases across multiple members. Is this one single model? Is this one database? Is this data at rest and/or available through an API

SUBJECT	DA - Harmonized Data Access
STATUS	Proposed
DECISION	Proposal: All access to "Harmonized Data" is through an API Member is responsible for the quality of the data retrieved and for certifying that a "request" for the data is supported.
DISCUSSION	If we determine that a standing harmonized store is not required, then we must establish an API with a standardized payload format that can be used to access the data. The member must "certify" that the data is available and quality in order to consent to a data extraction. The consent and certification can be captured on the ledger. The call to the API will come from the extraction processor. The extraction processor can run on the member node. Can the extraction processor run on the Analytics Node? If the extraction runs outside the member node, how does this work? Can it call the API directly? Must we use HLF to "transport" the data?

SUBJECT	DA - Harmonized Datastore DBMS Implementation
STATUS	Open
DECISION	Proposal: HDS will be a relational database. It cannot be a noSQL, graph, document DB etc. technical implementation of a HDS is non-prescriptive i.e. it can be MySQL, MS SQL, Oracle etc.
DISCUSSION	If data is at rest in the harmonized datastore, what is the technology? Does it need to be a single dbms? Should it be noSQL? Can it just be an interface?
