Hi all,

One of the LODD RDF datasets, Dailymed, seems to have created
identifiers for items without using the identifiers that are already
available. For example,
<http://www4.wiwiss.fu-berlin.de/dailymed/page/drugs/2892> is
equivalent to <http://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?id=678>
However, there is no way to know that from the RDF, even if you are
manipulating URIs to make things work. It may be more rational to have
<http://www4.wiwiss.fu-berlin.de/dailymed/page/drugs/6788> (doesn't
exist currently) to be equivalent to and link to
<http://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?id=6788>

Dailymed doesn't seem to be the easiest system to link to for what its
worth. For example, KEGG takes another method for linking, linking
from <http://www.genome.jp/dbget-bin/www_bget?drug:D02580> to
<http://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=AC387AA0-3F04-4865-A913-DB6ED6F4FDC5>
which then redirects to
<http://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?id=6788> .

Given that the downloaded XML,
<http://dailymed.nlm.nih.gov/dailymed/getFile.cfm?type=zip&id=6788>
only gives you the reference "ac387aa0-3f04-4865-a913-db6ed6f4fdc5"
(lower-case version of the KEGG reference) and not "6788" it might not
be easy for the RDF version to directly link, but it would be nice if
possible to reuse identifiers instead of making new ones up.

Cheers,

Peter
