With minor changes, dmBridge is compatible with CQR generated by the CONTENTdm® CQR generator. The CQR generator returns
code pointing to
/cdm4/browse.php; this needs to be changed to
/dm/objects to work with dmBridge.
Beginning with version 2.0, dmBridge includes a tool for converting CONTENTdm® CQR code to dmBridge format. This tool is accessible in the the section called “CQR” section of the Control Panel. This tool essentially automates what is explained below.
A custom query consists of the URL of a PHP script
/cdm4/results.php) followed by a series of "key-value pairs."
Below is a custom query with key-value pairs split apart onto their own lines for
/cdm4/results.php ?CISORESTMP=/cdm4/results.php &CISOVIEWTMP=/cdm4/item_viewer.php &CISOMODE=thumb &CISOGRID=thumbnail,A,1;title,A,1;note,A,0... &CISOBIB=title,A,1,N;note,A,0,N;creato,200... &CISOTHUMB=20%20%284x5%29;title,none... &CISOHIERA=20;creato,title,none,none,none &CISOTYPE=link &CISOOP1=exact &CISOFIELD1=local &CISOBOX1=vinas &CISOOP2=exact &CISOFIELD2=creato &CISOBOX2= &CISOOP3=exact &CISOFIELD3=origin &CISOBOX3= &CISOOP4=exact &CISOFIELD4=CISOSEARCHALL &CISOBOX4= &c=exact &CISOROOT=/showgirls
There are quite a few key-value pairs here. dmBridge needs only the ones that begin with CISOOP, CISOFIELD, CISOBOX, and CISOROOT (which mean matching mode, field, search string, and collection alias, respectively). As far as dmBridge is concerned, it's safe to delete the rest, or keep them - it doesn't matter. The above CONTENTdm® CQR converted to dmBridge format would look like:
/dm/objects &CISOOP1=exact &CISOFIELD1=local &CISOBOX1=vinas &CISOROOT=/showgirls
As you can see, we have dropped anything not starting with
CISOROOT. We have also dropped
CISOOP 2 through
CISOFIELD 2 through 4, and
CISOBOX 2 through 4,
because they were empty. (If the
CISOOP of a particular number is
empty, it and the corresponding
CISOBOX can be dropped.)
