Vocabularies for content keyword classification?

Hi!

I am in a government project where we are implementing RDF as a format
for legal information meta data from close to a hundred government
organizations. One ambition is to preserve the unstructured content
classification that many of these documents have today. Typically a
document has one or more keywords entered at the time of creation.
These are not from a controlled vocabulary and can be viewed more like
"tagging".

Since I am a beginner in the semweb field I would be grateful for your ideas.

1. What vocabularies have you used to define a single free text
keyword? We'd rather use an existing term instead of inventing our
own.

2. For those organizations that have made an effort to structure their
list of keywords, what would you advise them use to make it easy for
them to publish it online and make references instead of free text
keywords in their document metadata?

Thanking you in advance,

Peter Krantz
