+ // xxx temporary hack
+ // as of nov. 28 2013 we have here this.key='urn', but in any place where
+ // the code tries to access record[this.key] the records only have
+ // keys=type,hrn,network_hrn,hostname
+ // so for now we force using hrn instead
+ // as soon as record have their primary key set this line can be removed
+ // see also same hack in querytable
+ this.key= (this.key == 'urn') ? 'hrn' : this.key;
