Ty very much for the response Frans, I'm lucky and the "others"
virtuoso server that I use have this property so problem fixed, but
for the future, if i found one that haven't(as the property of the
dataset mean) there are other solutions that you know?
Greetings and ty again for the response solve many problems .
If there is no specification of dcterms:modified you could look if there
are any other dates or timestamps in de metadata. The dataset could have
a specification of dcterms:valid for instance. Or if it has only a
publication date (dcterms:issued for instance), one could assume that
there have been no updates after the first publication.
I am not an expert on Virtuoso, but I think that getting the
modification times of (collections of) triples is not possible for
regular users, unless these data are explicitly published. I can imagine
that is could be possible for administrators to get that information
from the transaction log.

Frans

Hi, everyone, I need to know as user when the content of the
virtuoso server (the triples) where i''m doing the queries was
last updatedor modified.
Is there a way to know through SPARQL? or anyway of knowing
without be the server administrator?
Ty in advance.
Hello Marco,
Wouldn't it be possible to update the dataset metadata to reflect
the time of the last update? I think most users would look for
dcterms:modified.
Greetings,
Frans
