Hi Jörg,<br/>
<br/>
thanks for your suggestion, I would propose to use the subset of ISO<br/>
8601 which corresponds to the xml dateTime type:<br/>
<br/>
<a href="http://www.w3.org/TR/NOTE-datetime" target="_blank">http://www.w3.org/TR/NOTE-datetime</a><br/>
<br/>
(and you are right, we should add this to the list of preferred standards)<br/></div><div name="quoted-content"><br/>
This leaves out very unusual date formats like 2009-W53-7<br/>
<br/>
Unfortunately this will not solve all the problems mentioned in<br/>
<a href="http://trac.clarin.eu/ticket/36" target="_blank">http://trac.clarin.eu/ticket/36</a> as we do not have control over the<br/>
metadata of external (non-clarin) metadata providers.<br/>
<br/>
best,<br/>
