xAPI activity ID / IRI issue
When exporting as xAPI rise creates activity ids like this in the tincan.xml file :
<activity id="http://Ipso Lorem : Part One/lHgv2evYuSgsWzNx1zb86pTxgryPmdFO/cjqpngf9j002k3m5rddvqlfyh" type="http://adlnet.gov/expapi/activities/cmi.interaction">
Are colons allowed in the activity id unencoded? The xAPI spec says these are supposed to be IRIs.
Can you point me to any information on how rise creates these ids?
