Hi Kurt,

Note you can also use the following linked data validator to test your URIs:

Hi Kurt,

Where are you actually seeing the rfc1808_parse_uri error, can this be produced with a curl command for example with something like:

curl -I -H "Accept: text/html" http://dbtune.org/cmn/resource/WAGN

Which produces the following on my machine:

HTTP/1.1 303 See Other
Date: Mon, 02 Feb 2009 21:10:31 GMT
Server: Virtuoso/05.09.3035 (Linux) x86_64-redhat-linux-gnu
Content-Type: text/html; charset=UTF-8
Accept-Ranges: bytes
Location: http://dbtune.org/cmn/page/WAGN
Connection: close

Can you provide the output of running the following query against the Virtuoso server with isql to list all rewrite rules on your server:

select DB.DBA.URLREWRITE_DUMP_RULELIST_SQL (URRL_LIST) from URL_REWRITE_RULE_LIST

Can you also provide more details on these redirects from apache to Virtuoso ?

For the HTML representation, you just want to redirect the
resource identifier to the information resource description page
(description.vsp) using:
 /about/html/<http://dbtune.org/cmn/resource/WAGN>

yes this is more like what's in the examples but now i get:

Error 22023

SR014: Function rfc1808_parse_uri needs a string or wide or a UNAME as
argument 1, not an arg of type DB_NULL (204)

could this be b/c of my kludgy redirects from apache to virtuoso?

curling http://dbtune.org/cmn/resource/WAGN or
http://dbtune.org/cmn/data/WAGN does give the appropriate response as
far as i can tell

cheers!
