I feel way behind in this area. I have successfully used XSLT to insert in Dublin Core metadata into the header of an HTML page, but I would like to support multiple resources, etc. From looking around, it seems the best format to use is COinS, but the format is a bit more, er, obtuse than dublin core.
Has anyone done this? care to share some sample XSLT? Am I going about this all wrong?
(Also, I debated whether this should go in metadata or programming. Feel free to chime in on that as well)

I would definitely categorize this as a programming question; the metadata is there, now you want to do something else with it.
The answer is, well, it depends. Really this depends on what version of TEI you're using and how the header elements are encoded. The "hard" part of this is really encoding the special characters contained in the text (spaces, etc.). There is, however, a nice function (I believe it's in Saxon) named url:encode(string).
As an approach, take the fields you want to provide to the z39.88 standard (http://ocoins.info/) and assign them in to key-value pairs (e.g. <xsl:variable name="btitle" value="/TEI.2/teiHeader/fileDesc/titleStmt/title" /> and string them together in your span element that is nested somewhere in your HTML body element:
<span class="Z3988" title="url:encode($btitle...)" />
Knowing more about the TEI version, and which XSLT processor you're using would also help.
BTW, if you don't have URL encoding available on the processor, check out this xslt http://skew.org/xml/stylesheets/url-encode/url-encode.xsl
We are using TEI P4 or P5 (depending on the age of the file), and the Saxon 9 processor (the free one, is that 9b?) I think the method you described will work- I'll give it a try.
Followup question: is COinS still the recommended data format for adding metadata of items to pages?
COinS is awful because OpenURL is awful, but it works. Something else you might want to look at is embedded RDF.
Replying to @Wayne Graham's post:
Want to echo and reinforce Wayne's point about how the header elements are encoded. Not sure the degree to which this is others' experience, but I've seen wide variation there. I'm guessing that you might need to spend some time understanding the original encoding as you move to producing those mappings. Hopefully the info to guide you will be there in the encoding description.
Good luck!

Replying to @Karin Dalziel's post:
Here is what I put in my XSLT param file, from the TEI-provided xslts, in order to generate COINS metadata in HTML pages that have been generated from a TEI P5 master:
<!-- COINS Metadata -->
<xd:doc class="hook">
<xd:short>for adding COINS metadata</xd:short>
<xd:detail>coins metadata for the edition generated at http://generator.ocoins.info/.</xd:detail>
</xd:doc>
<!-- Here is what it should look like when in the HTML: <span
