Peer-Reviewed Publications

Sixteen peer-reviewed journal articles and full conference proceedings papers across the openEHR and MLHIM research lineage, 2002 to 2016. Fifteen carry a resolvable DOI; the 2010 congress proceedings paper predates DOI assignment by that congress. SDC4 inherits the modeling approach, not the citation record. Letters, posters, workshop papers, abstracts and the thesis are listed separately below.
