Hmm .. just realized the new Worldcat identities service does something cool:

curl http://orlabs.oclc.org/Identities/find?fullName=berners-lee%2C+tim+
<?xml version="1.0" ?>
<?xml-stylesheet type="text/xsl" href="NameFinderResults.xsl"?>
<nameAuthorities query="berners-lee, tim" maxList="10" hitCount="53">

Hi Bruce!

Wow! really nice find! :)

This has to keep in mind. This is a wonderful source of information
about authors of many things. In fact, I will look to create linking
(sameAs) from worldcat to the Music Ontology (musicbrainz, etc)

This is one thing among many others!

Take care

Nice find Bruce! It's nice that the URI references are also
retrievable in the same way:

curl http://orlabs.oclc.org/Identities/key/lccn-no99-10609 | xmllint
--format - | less

Cool.

It's struck me that Ian's worry about blank nodes is partly a function
of note being able to easily assign pre-exising URIs to strings. Perhaps
services like this can help?

I wonder if we get them to set up the output for GRDDL?

I wrote this little XSLT that converts the output to a simple FOAF file,
complete with URI:

</xsl:stylesheet>

Output:

</rdf:Description>

</rdf:RDF>

Reminds me, we really ought to have a separate property (from foaf:name)
for the sort form of the name.

Hah, rough two:

<xsl:template match="authorityInfo">
