It’s also worth pointing out that the music reviews are published under a CC license (non-commercial, attribution share-alike).

Nice write up of the structure BTW

Comment on Quick OpenCalais Hack by Tom Tague

Leigh:

Tom Tague from OpenCalais here.

Thanks for the post. This is great. We always appreciate it when someone takes the time to publish examples / cookbooks that help jump start others exploration of Calais.

For those of you not directly involved in NASA space flight data you might see interesting results taking in full text news feeds such a the Huffington Post or the Reuters Spotlight feed (or many others). By automatically adding semantic metadata (entities are interesting - but events like natural disasters, product recalls, management changes, bankruptcies are even more so) you can quickly create a very interesting exploratory database around a particular domain (sports, business, etc). With a combination of SPARQL plus the Calais Linked Data assets you can ask interesting questions like “What natural disasters were mentioned in relation to South America” or “What Sports Teams are mentioned that are located in New York”. You get the idea..

Again, thanks for the examples.

Regards,

Another recent update has been to the ChangeSet class, which can now do batch changesets - just don’t provide a
subjectOfChange parameter
You can also pass any kind of RDF to the ‘before’ and ‘after’
parameters - RDF/XML, turtle, triples array, index array
You can also add extra metadata to each of the changesets created like
this:

$args = array( 'after' => $this->g1, 'before' => array(), 'properties' => array( 'http://purl.org/dc/elements/1.1/source' => array(array('value' => 'http://example.org/home.rdf', 'type' => 'uri')), ), ); $this->ChangeSet = new ChangeSet($args);
This will add the properties under the ‘properties’ key to each
changeset created.

Hmpf, the URI got filtered out. This was supposed to be “So in the log vocabulary (used by Cwm) there is http://www.w3.org/2000/10/swap/log#semantics“.

Hi Simon, Tim,

Yes, I wasn’t all that sure about using that frbr property; it was the nearest I could find at the time. log:semantics would be far better. I was also thinking perhaps the proposed awww:representation property in http://esw.w3.org/topic/AwwswVocabulary might be suitable, but log:semantics is better.

I would be interested in hearing if LOD publishers prefer to use this slightly more complicated (because it introduces another node and another level of indirection), but more precise modeling.

I’m not very convinced of the usage of FRBR here (partly maybe because I’m less and less convinced FRBR is a suitable model for designing ontologies but that’s another topic).
So in the log vocabulary (used by Cwm) there is . Look at the description, I think this might be a good property for linking from an information resource to a graph.

Regards,
Simon

@prefix log: .

For the record, there is log:semantics which cwm understands as a builtin function
and is exactly the relation between the document and the graph.

So you might say

[ is log:semantics of ]
dcterms:isPartOf .

or as a path

!log:semantics
dcterms:isPartOf .

Comment on Pho: A Ruby Client for the Talis Platform by Elliot Smith

Any chance you could support changesets? I can’t see any reference to it in the documentation, and this is the part of the Platform API where I need most help.

Thanks.
