[jira] Commented: (CLEREZZA-303) Some triples with dates have another date after storage in tdb graph

    [ https://issues.apache.org/jira/browse/CLEREZZA-303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12913596#action_12913596 ] 

Reto Bachmann-Gmür commented on CLEREZZA-303:
---------------------------------------------

I think we have this problem also for other datatypes with the TDB,  TDB stores the value of typed literals rather than their lexical form.
