Yes, I tend to agree. One thing that has always worried me about
embedding DC in HTML is that very often DC.Title, DC.Subject and
DC.Description duplicate information that is already encoded into the
document using the HTML <title>, <meta name="keywords" ...> and <meta
name="description" ...> tags. (I know this isn't always the case, but it
is quite often).
These days, I'm not convinced by the embedding metadata in HTML approach
anyway. Much better to link to a separate metadata record using the
<link rel="meta" href="...">
as is done on the http://purl.org/dc site.
As a general rule...
- store your content in a backend database if you can
- store your metadata in a backend database (usually the same I guess?)
- generate your HTML dynamically from the database and embed HTML <title>,
<meta name ="keywords"> and <meta name="description"> tags based on
metadata in database. Also embed <link rel="meta" href="..."> tag.
- dynamically resolve the rel=meta URL into an RDF/XML description (or
whatever) based on metadata in database.
Then you'll be well placed to export your metadata using Open
Archives Initiative harvesting framework (or whatever) in the future.
Don't ask me to recommend tools to do all this :-), though I think there
has been at least one proposal to do part of this in Zope (www.zope.org)?
Just a few thoughts...
