The Organisation Data Service (ODS) release two XML files of organisation data:
- full file: HSCOrgRefData_Full_yyyymmdd.xml
- archive file: HSCOrgRefData_Archive_yyyymmdd.xml
These files are available monthly to download from the Technology Reference data Update Distribution (TRUD) service. From these files a local baseline of organisation data can be created, which can then be updated on a daily basis by connecting to the ODS ORD API.
