It may be that markup is not the right hammer for this problem. Our search engine handles multiple DTDs by mapping the elements into common search meta data elements. DC:Creator -> author GILS:Originator -> author TEI:docAuthor -> author and so on. So the documents can remain legal and "pure" with respect to TEI or GILS, but users can search them with a common model. In a sense, this is the same as having separate style sheets for each format, but making them all look the same. You could even consider making a search-specific style sheet (XSLT-only) which transformed each DTD into the common search form. Whether it is implemented with a literal style sheet or not, that is a useful model for thinking about it. If there are separate sets of meta data elements (Dublin Core, GILS, US-MARC), then you'd need a separate transformation for each. Ultraseek Server doesn't implement it that way, partly because XSLT didn't yet exist at the time, and mostly because the indexer has no other use for a DOM, and SAX-style stream/event parsing is more efficient for our purposes. At first glance, it sounds like Ultraseek Server might already implement what you want, so it is at least worth checking it out. If you want more details about our XML support, I wrote it, so you can ask me. And I like the idea of "Creator is Tillich". Shouldn't that be "Ground of Creator is Tillich"? wunder -- Walter R.
