Health informatics -- Document registry framework
ISO/TS 27790:2009 also references a number of companion standards-based specifications that offer optional extensions to enhance the basic capabilities offered by IHE XDS. It references the support of the following.
- An XDS extension supporting the fragmentation of the content of the documents into two parts: a header fragment and a body fragment. This separation scheme enhances confidentiality because the gathering both of header and body and their relational information involves cracking into multiple repository servers. This has been developed as an IHE Korean Extension on the IHE XDS Profile.
- A series of security- and privacy-related IHE profiles, such as Patient Identification Cross-Referencing (PIX), Patient Demographics Query (PDQ), Basic Patient Privacy Consent (BPPC), Cross-Enterprise User Assertion (XUA).
