| Thanks I will use it like this for the moment,
Would it be a good idea to look into an xsd for ccREL?
There is already a good human readable guideline, but as far as I can find no automated way of checking the validity of data structured in ccREL.
Looking deeper into OAI-PMH I see that they have some structures available to put rights informationan, although this refers to the metadata itself not the object is describes. Adoption of ccREL in a future version of OAI-PMH could benefit the use of ccREL greatly as well as giving archives a way to more accurately describes the rights status of the works they put out there.
Cheers,

I used this as my starting point:
http://www.openarchives.org/OAI/2.0/rdf.xsd
which is the structure to include rdf in the OAI protocol
I derived from that that construct needs to have the following form:
<rdf:RDF
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xsi:schemaLocation="http://www.w3.org/1999/02/22-rdf-syntax-ns#
http://www.openarchives.org/OAI/2.0/rdf.xsd">
</rdf:RDF:>
Then I probably made a mistake by replacing
http://www.openarchives.org/OAI/2.0/rdf.xsd
with
http://creativecommons.org/ns#
instead of replacing the first
http://www.w3.org/1999/02/22-rdf-syntax-ns#
I am equally not sure about the schemalocation.
Probably the right way to use ccREL here is:
<rdf:RDF
xmlns:cc="http://creativecommons.org/ns#"
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xsi:schemaLocation="http://www.w3.org/1999/02/22-rdf-syntax-ns#
http://www.openarchives.org/OAI/2.0/rdf.xsd">
</rdf:RDF:>
Would you agree?

Hi Maarten,
We do not currently have an XSD for the CC namespace, so assuming you
can include RDF directly, that seems like the easiest way to get
started. Note that I'm not an expert on OAI-PMH, so I'm not certain
that's possible.
That said, the example you gave seems a little strange to me. In the
rdf:RDF element, you declare the rdf as
"http://www.w3.org/1999/02/22-rdf-syntax-ns#". Under normal RDF/XML
rules (assuming those apply here) "rdf:attributionName" would be
interpreted as http://www.w3.org/1999/02/22-rdf-syntax-ns#attributionName.
I don't think that's what you're going for. I'd expect to see
something like:
<rdf:RDF
xmlns:rdf=”http://www.w3.org/1999/02/22-rdf-syntax-ns#”
xmlns:cc="http://creativecommons.org/ns#">
and then "cc:attributionName", "cc:attributionUrl", etc. I'm also not
clear what the point of xsi:schemaLocation is on rdf:RDF.
Apologies if my comments reveal some deep-seated misunderstanding of
OAI-PMH. It'd be great to have a functional example of CC REL in
OAI-PMH, so I'd love to work through the issues and get this
documented.
Regards,
Nathan

Hello list,
I'm trying to make an implementation of ccREL for OAI-PMH to communicate
specific ccREL information. I could not find examples or explanations how
this could be added so I thought I post it on the list.
I've used the standard RDF implementation to bypass the need to have an xsd,
which as far as I know there is none of ccREL is there?
That would result to a record that would like this? Wouldn't it?
<record>
<header>
