Dear All My name is Athanasios Anastasiou and i am with the Signal Processing and Multimedia Communications Research Group at the University of Plymouth, UK.
The university is currently leading a 31 institutions partnership in a 4 year European FP6 program called BIOPATTERN. More information can be found in http://www.biopattern.org or our revised website at http://www.biopattern.org/Test1 by following the link, "About the NoE." I have been reading the rather detailed specs documents of openEHR and i believe that i am ready to take the plunge and actually implement a proof-of-concept software making use of it. I am focusing on implementing a subset of the standard and before i start i thought about posting some general questions that i have about openEHR. 1. Is there a set of guidelines regarding the implementation technologies used that make a piece of software "openEHR compliant?" For example, the standard specifies that an openEHR repository should be tracking the changes in the records. Is there a preffered implementation for this or can i use whatever does the job? 2. The messaging section is blank (or so i think :-) ). So i am wondering if there is a messaging pre-standard or other specification about the exchange of messages specific to openEHR. If there is no such a thing, should i rather assume that the corbamed or CEN standards cover this section? 3. What exactly does the ehr_extract entity represents in everyday medical practice? For example, does it refer to the EHR view that a specialist defines? Does it represent the return results of a query towards the repository? 4. Just to clarify something. As far as i understand it, binary files from various modalities are stored as URIs to the underlying file system (whatever that is). Is this correct? Finally, i would just like to point out that several links, over at www.openehr.org that are supposed to be pointing to implementations or implementation details are inoperable or incomplete for example: http://www.shef.ac.uk/uni/projects/bstd/homepa.htm http://www.sincromed.ro/bstd.htm GEHR Australia, several interesting sections in many documents are empty http://www.sdhis.nhs.uk/erdip/public/index.shtml http://www.ehr.chime.ucl.ac.uk/docs/Kalra,%20Dipak%20%28PhD%202002%29.pdf http://www.openehr.org/projects/downloads/EU-EHR-demonstrator-sites.jpg Looking forward to hearing from you Athanasios Anastasiou BIOPATTERN: Data Acquisition Task Force University of Plymouth UK
