Hi all,

I had a question about the data type DV\_EHR\_URI. The specifications are a bit vague on this type:

[http://www.openehr.org/local/releases/1.0.1/uml/Browsable/\_9\_0\_76d0249\_1109068357612\_21665\_4527Report.html](http://www.openehr.org/local/releases/1.0.1/uml/Browsable/_9_0_76d0249_1109068357612_21665_4527Report.html)

It only states that it should start with ‘ehr’. How should an internal link to an object in an EHR look like? Are there any conventions, examples or ideas about that?

Thanks in advance,

Kevin Keene

Have a look at the Architecture Overview, there is a section on paths and uris. Section 11 from memory.
