<h1><span style="font-style: italic;">open</span>EHR
Specification Project - Release 1.0.1 <br />
Release Notes
</h1>
<hr style="width: 100%; height: 2px;" />
<h2>Overview</h2>
Release 1.0.1 is the corrective release to Release 1.0. It fixes
the typographical errors from Release 1.0, includes significant
improvements in the explanatory text of the documents, and includes around 50 CRs (see <a href="history.htm">History</a>). The majority of these have been raised by members of the <span style="font-style: italic;">open</span>EHR
community either due to detailed review, or due to working with
implementations. The release now appears to be extremely stable. We
believe this release is a true milestone in health computing.<br />
<br />
Functional changes to the models include the following:<br />
<ul>
<li>numerous improvements to the Architecture Overview document, including new section on terminology and improved path syntax;</li>
<li>original documents can now be linked to or carried inline COMPOSITIONs, in a flexible way (using <span style="font-family: monospace;">rm.common.archetyped.FEEDER_AUDIT</span>);</li>
<li>improvements in the
<span style="font-family: monospace;">rm.common.change_control</span> model of versioning, ready for use in <span style="font-style: italic;">open</span>EHR EHR Extract specification;</li>
<li>numerous corrections to the <span style="font-style: italic;">open</span>EHR Support Terminology;</li>
<li>improved model of identifiers (<span style="font-family: monospace;">rm.support.identification</span>);</li>
<li>improved modelling in Quantity data types (<span style="font-family: monospace;">rm.data_types.quantity</span>) including:</li>
<ul>
<li>replacement of <span style="font-family: monospace;">DV_QUANTITY_RATIO</span> by <span style="font-family: monospace;">DV_PROPORTION</span>;</li>
<li>addition of <span style="font-family: monospace;">normal_status</span> attribute to <span style="font-family: monospace;">DV_ORDERED</span> (provides HHH, HH, H, N, L, LL, LLL markers);</li>
<li>addition of <span style="font-family: monospace;">magnitude_status</span> attribute to <span style="font-family: monospace;">DV_QUANTIFIED</span> (provides =, <, <=, >, ?=, ~ markers);</li>
<li>simplifed model of amounts and absolute quantities (added abstract classes <span style="font-family: monospace;">DV_AMOUNT</span>, <span style="font-family: monospace;">DV_ABSOLUTE_QUANITTY</span>, <span style="font-family: monospace;">DV_TEMPORAL</span>)</li>
</ul>
<li>corrections to the date/time data types (<span style="font-family: monospace;">rm.support.assumed_types</span>, <span style="font-family: monospace;">rm.data_types.quantity.date_time</span>), which have now been
aligned with the ISO 8601 standard;</li>
<li>an EHR access control object has
been added (<span style="font-family: monospace;">rm.ehr.ACCESS_CONTROL</span>), along with an overall description of how security works;</li>
<li>the definition of
various
identifiers in support.identification was tightened up, and the use of
identifiers made more precise;</li>
<li>corrected inheritance errors in use of <span style="font-family: monospace;">rm.common.archetyped.LOCATABLE</span>;</li>
<li>improvements to <span style="font-family: monospace;">rm.common.resource</span> package for use in archetypes;</li>
<li>improved model of <span style="font-family: monospace;">am.archetype.constraint_model</span>;</li>
<li>numerous improvements to <span style="font-style: italic;">open</span>EHR Archetype profile (<span style="font-family: monospace;">am.openehr_profile</span>)</li>
<li>improvements to ADL including:</li>
<ul>
<li>proper definition of quoting and unicode;</li>
<li>addition of generic typenames to ADL;</li>
<li>better alignment of data/time constraint expressions with ISO 8601.</li>
</ul>
</ul>

Many people helped bring this release to fruition, including implementers and reviewers. Thanks to all the people on the <a href="project_team.htm">project team</a>
