Subject: googlemap resources now displayed as hrn’s again
X-Git-Tag: myslice-0.3-0~103^2~1^2~3
X-Git-Url: http://git.onelab.eu/?p=myslice.git;a=commitdiff_plain;h=02a3498e95ce42bf032edfebf99910f9a65290c2

googlemap resources now displayed as hrn’s again
cleanup code to distinguish between a record’s id’ (based on primary key as per this.key) and label (hrn)
there should not remain any explicit reference to either urn or hrn in this code
