Since version 1.2 the Broker allowed specific attributes from matched objects to be returned in the result set. However, there was no real support for this in BrokerQuery.pl.cgi. With version 1.3 it is possible to request SOIF attributes from the HTML query form. A simple approach is to include a select list in the query form. For example:
<SELECT MULTIPLE NAME="attribute">
<OPTION VALUE="title">
<OPTION VALUE="author">
<OPTION VALUE="date">
<OPTION VALUE="subject">
</SELECT>
In this manner, the user may control which attributes get displayed. The layout of these attributes when the results are displayed in HTML is controlled by the <FormatAttribute> specification in the BrokerQuery.cf file described in Section 5.4.1.
