My attempt to make a context set document for the treatment of GILS in CQL is at http://www.gils.net/context-set.html . Cases of multiple index names with the same semantics (e.g., author, creator, originator), are shown in the same row to have these treated as exact aliases. Also, you may notice a couple of new elements that are emerging from the Categorization of Government Information work under the E-Government Act. Please do let me know whatever I have gotten wrong!
