John discusses his program to add LC subject headings to titles in the Online Books Page based on the LC classification
From Glenn E. Patton:
"To get a sense of which MARC data elements are used in the various indexes for WorldCat, take a look at "Searching WorldCat Indexes" (http://www.oclc.org/support/documentation/worldcat/searching/searchworl
dcatindexes/). Click on "List of Fields and Subfields Indexed in Tag Order" in the navigation bar on the left of the screen to see a list of MARC elements and the indexes in which they are used."
Interesting post on federated searching. Why imporved mapping doesn't work, and what we might do to improve the results sets for users.

CQL::Parser is a Perl module for parsing Common Query Language statements.
CQL is a formal language for representing queries to information retrieval systems such as web indexes, bibliographic catalogs and museum collection information. The design objective is that queries be human readable and writable, and that the language be intuitive while maintaining the expressiveness of more complex languages.
CQL::Parser will allow you validate statements, and parse them into a parse tree which you can then programatically walk and use. For your convenince there are methods for converting the CQL parse tree into Swish and Lucene queries as well as XCQL (an XML representation of CQL).
use CQL::Parser;my $parser = CQL::Parser->new();
my $root = $parser->parse('dc.creator="clinton"');
my $swish = $root->toSwish();
my $lucene = $root->toLucene();
my $xcql = $root->toXCQL();
