How does GILS relate to the Bib-1 Attribute Set in Z39.50?
The Bib-1 Attribute Set is commonly supported by most implementations of ANSI Z39.50, although protocol compliance does not require support for Bib-1. GILS is an applications profile that specifies just exactly which functions are supported at a compliant server. Among the functions is support for a set of numbered search attributes called the GILS Attribute Set. The GILS Attribute Set is available as a separate Attribute Set but all of the GILS attributes are included in the Bib-1 Attribute Set as well. (see ).
