Given recent discussion let's reconsider the proposal we've put up for word masking. Should we withdraw it? After all, it's purpose was to support cql searches, and if we're back to defining word indexes, we don't need it, as long as we have a way to map to Z39.50 attributes -- which we do for attribute architecture but not for bib-1. So I suggest the following: 1. withdraw the word masking proposal. 2. propose three new structure attributes for bib-1: left-truncation on word boundary right-truncation on word boundary adjacentWords 3. If these attributes aren't accepted then we just map to attribute-architecture-friendly combinations. --Ray
