Description:
Where to find documentation to add a sort by "date"choice in RD?

Resolution:
Please refer to the last section of the "Digitool System Configuration Guide".
Below is the essential information from it:

4.4.2.1 Definition
Sort is defined in two configuration files in the silo’s tab directory. The first sort definitions are defined in the table /exlibris/dtl/u3_1/dtle/tab/tab_sort. Tab_sort definitions are those that are used to build the database’s sort index. The Resource Discovery’s availability of these defined sort codes are defined in the general configuration file
/exlibris/dtl/u3_1/gen01/tab/www_r_silo_conf.xml.

4.4.2.2 Configuration

As mentioned, the tab directory file tab_sort holds the sort code definitions for the
silo. An example of the default setup of sort codes:
!1 2 3 4 5 6 7 8 9 10 1 12 13 4 15 16 7 18 9
!!-!!-!!!!!-!!!!!-!-!!!!!-!!!!!-!-!!!!!-!!!!!-!-!!!!!-!!!!!-!-!!!!!-!!!!!-!-!!-!!
01 102## a 00 00
02 103## a 00 00
03 101## a 00 00
04 MED02 b 00 00

Each row in tab_sort represents a different Dublin Core internal tag by which the sort codes will be built.

To activate the sortability options from the Resource discovery, the appropriate section of the www_r_silo_conf.xml file must be defined. The following represents a sample entry for sorting title with sort code 03 Ascending and secondary sort on Creator Ascending:
<sort_codes>
<sort_code>
<code>03---A01---A</code>
<sort_name lng="ENG">Title/Creator</sort_name>
<option_name lng="ENG">Title</option_name>
</sort_code>
</sort_codes>
