It was pointed out a few days ago that the FOAF files we’d been using for creating the people.apache.org site weren’t valid RDF! They had been at various points earlier in the development, but as I added various additional pieces of information it seems I stopped checking the validity of the output. Whoops!
The output has been corrected and a discussion about some more changes is taking place, but one aspect that I’d like to find a way to add back in languages for weblogs. How do you add a language to a weblog entry in a FOAF file?
The site has been live for a short while now, so anyone have any comments to pass back? If you have comments, good ro bad, send them along to site-dev at apache dot org and we’ll be happy to listen. The site may have been developed by a small group, but it really belongs to every committer at the ASF!
http://dublincore.org/documents/dcmes-xml/#sec2-5 says “XML provides an xml:lang attribute that can be used on any element. This provides a way to describe the language used for the content of the element. The DCMES provides a Language element which is used to describe the language of the resource”
So I think it would look like the following, using xml:lang to show that the title I provided is an English one, and dc:language to show that the foaf:Document is in English:
Dave Brondsema’s blog
en
Grr.. no preview nor warnings about stripping tags. Let’s try again:
{foaf:weblog}
{foaf:Document rdf:about=”http://brondsema.net/blog”}
{dc:title xml:lang=”en”}Dave Brondsema’s blog{/dc:title}
{dc:language}en{/dc:language}
{/foaf:Document}
{/foaf:weblog}
dc:language looks like what we need. I guess we should also reflect the language of the title, though I’m less convinced by that. After all, as long as it’s correctly encoded it should display OK?
Yep, I think so. Practically speaking, using xml:lang on dc:title would only be needed if you wanted to distinguish an English title and a Spanish title, for example.
