Background
Update: The API has been extended to apply to Evaluations as well as Entities.
Update: The API has been extended to apply to Teams. See Teams
Update: We allow updating of Access Requirements by the ACT. We allow Access Requirements to apply to Folders as well as Files. Entities inherit any access restrictions applies to Folders which contain them.
Update: We add inheritance of access requirements: Each entity inherits the access requirements of its ancestors (e.g. the Folder(s) containing a given File).
IRB-approved versions of all of the 'data access documents' :

- Data layer access in Synapse requires one or more approval steps.
- In Synapse granting data access is synonymous with providing the URL to the stored data.
(This URL may have an embedded access token.)
- Currently (i.e. as of Jan. 2012), the backend Prior to this work, the back end has a representation of EULAs and of Agreements (i.e. that a particular user agrees to a EULA)
- The work flow logic for creating the agreement is embedded in the Web client, so other clients would have to maintain duplicate logic. Specifically, the web client has the following logic:
1) When a user tries to download a layer, the Web client checks whether the parent dataset has an associate EULA;
2) If there is an EULA, the web client checks whether there is an Agreement, owned by the User and referencing the dataset and EULA;
3) If there is a EULA but no Agreement, the web client prompts the User to sign the EULA, creates the Agreement, then allows the download.

Tier 3: (Tier 1) + (Tier 2) + User access must be requested/approved through an Access and Compliance Team (ACT).
Design
Database
We have two tables , one for Requirements and Approvals: ACCESS_REQUIREMENT , with a foreign key to a node (object) and one for ACCESS_APPROVAL, having contains the requirement information, while NODE_ACCESS_REQUIREMENT 'joins' it to the JDONODE table, saying what entities are affected by the requirement. ACCESS_APPROVAL has foreign keys to ACCESS_REQUIREMENT and principal. The first imposes a requirement for access to the node. The second fulfills the requirement, for a given principal. Both The requirement and approval tables have an "ENTITY_TYPE" field (populated from an ENUM) and a "SERIALIZED_ENTITY" field, a BLOB, allowing them to have variable content, so they can be used for Tier 2 or Tier 3 requirements.

We introduce JSON schemas for the generic interfaces AccessApproval and AccessRequirement, and schemas for specific types, TermsOfUseAccessRequirement, TermsOfUseAccessApproval (for tier 2 data), ACTAccessRequirement, and ACTAccessApproval (for tier 3 data).

Web UI
TBD
When a user clicks Download on the page for a Data object having a Terms of Use access requirement, they are presented with a dialog showing the text from the access requirement, as shown below. If they accept the terms, then an access approval is created and the Download link is presented.
When a user clicks Download on the page for a Data object having an ACT access requirement, they are presented with a dialog showing the text from the access requirement, as shown below. Once they contact the ACT team, someone from the team may create the approval object on their behalf, after which they may download the Data without encountering the dialog.
