Ruby implementation of openEHR

h1. YADL

h2. Background

ADL is one of the openEHR official formalism to express archetype, defined as "ADL 1.4"http://www.openehr.org/svn/specification/TRUNK/publishing/architecture/am/adl1.4.pdf

Many archetypes are registered on "Clinical Knowledge Manager":http://www.openehr.org/knowledge/ shown such as bellow:

<pre>

archetype (adl_version=1.4)

	openEHR-EHR-OBSERVATION.body_temperature.v1

Additional clusters can be included to provide additional state data - including environmental conditions, menstrual cycle details and exertion details, where appropriate.

Please Note: The site and method of recording may need to be displayed to the end user to facilitate accurate interpretation of the temperature recorded.">

			misuse = <"This archetype is not to be used to record the temperature of any other object.

This archetype is not to be used to record the temperature of a part of the body in isolation e.g. temperature of the sole of the foot as a part of chronic diabetes management.">

			purpose = <"Zur Messung der Temperatur einer Person - als Surrogat for die Temperatur des gesamten Körpers.">

			use = <"Benutzt zur Aufzeichnung der gesamten Körpertemperatur einer Person oder eines Körpers.

Wenn benötigt, können zusätzliche Cluster Archetypen eingefügt werden, um zusätzliche Statusdaten bereitzustellen - darunter Details zu Umgebungsbedingungen, Menstruationszyklus und Betätigung.

Otherwise, ADL is not so common formalism such as XML or OWL.

XML serialisation is considered more popular alternative to express archetype.

XML form of archetype is shown bellow
