Creating a summarizer for a new SGML-tagged data type

To create an SGML summarizer for a new SGML-tagged data type with and an associated DTD, you need to do the following:

1. Write a shell script named FOO.sum which simply contains

           #!/bin/sh
           exec SGML.sum FOO $*
   

2. Modify the essence configuration files (as described in Section 4.5.4) so that your documents get typed as FOO.

3. Create the directory $HARVEST_HOME/lib/gatherer/sgmls-lib/FOO/ and copy your DTD and Declaration there as FOO.dtd and FOO.decl. Edit $HARVEST_HOME/lib/gatherer/sgmls-lib/catalog and add FOO.dtd to it.

4. Create the translation table FOO.sum.tbl and place it with the DTD in $HARVEST_HOME/lib/gatherer/sgmls-lib/FOO/.

At this point you can test everything from the command line as follows:

        % FOO.sum myfile.foo
