UK Biobank data is split into tiers according to the cost of accessing it via various methods. There are two methods of access:
- Online : in-situ online access via the RAP
- Showcase : download* via baskets or from the built-in portal
The tier associated with a particular field is displayed in the format "oA sB" where A and B are the minimum tiers required to access that particular field via the Online and Showcase routes respectively. If a field is not accessible via a particular route then an "X" is displayed.
To illustrate: a field labelled "o1 s3" would require an Application to be in tier 1 to access it online with the RAP and in tier 3 to access its content via the Showcase routes. Thus an Application which has paid a tier 2 fee could access this field via the RAP but not any other route.
* Note that Showcase downloads are only available to Applications which have an approved download exemption in place. Default access for all projects is via the RAP. For additional information about exemptions see:
