Hi everybody,
Before I go ahead, let me apologize for being a new comer to the world of semantic web and drupal .. may be some of you might find it funny .. but I have spent the last few hours installing the Drupal Modules relations-6.x-1.0-alpha5 , rdf-6.x-1.0-alpha5 , sparql-6.x-1.0-alpha1 and exhibit-6.x-1.0-alpha2 and reading about semantic web , I have understood the subject - predicate - Object logic .. have designed the RDF logic on paper , created two node types in Drupal ... however I am struggling to establish the relation between them in Drupal.
What I have done so far .. created two node types .. 1) Player 2) Game . they have URLs of the format http://localhost/player/xxx and http://localhost/game/xxxx . The players can be master ( or novice) of any number of games .. and the members of the community should be able to track all the players for a given game and vote a player as the master of the game.
Where does semantic web come into all this? Read that all the information on wikipedia is available in the semantic format .. so thought it might be cool if information from wikipedia ( and other sources ) could be connected to the game using the semantic web modules and also to establish the relationship between the players and the game.
I can see the RDF mapping field in the Player and Game content types and I have entered the RDF classes for them that I put in my design on paper. However I am struggling to proceed further...
It would be really helpful if somebody could post the link to a tutorial where a simple application has been created in Drupal using the semantic web modules for newbies like me to understand the concept and move ahead.
Sorry ..if this posting is not relevant to this group or too juvenile to be raised in this group....

Me too
I agree with this line of questioning. If I add all these semantic web contributed modules (RDF, CCK RDF, EVOC, SPARQL, Relations), is it anyway to make it useful? For example the module CreateFromWeb lets me create nodes containing information from wikipedia. Useful. It would be even more useful if I could mark all my fields with RDF and import data via sparql, especially from diverse sources (All those terabytes of data Amazon says they have made available).
any news on this?

hi
any update on this?
I'm not a newcomer to the semantic web. I normally use virtuoso, protege and topbraid to combine and create rdf data and query it using Sparql. I thought I'd try and give it a go in Drupal. I've added RDFx,SPARQL API, RDF UI, External RDF Installer, Sparql endpoint and Entity API.
I've loaded the core ontologies. So I would expect a sparql query at the sparql endpoint such as this
select ?s ?p ?o
where {
?s ?p ?o .
}
to return all the data from the graph - but I get nothing ....
Is there some easy to follow example that I can use to test my approach?
To have a SPARQL endpoint on
To have a SPARQL endpoint on your site, I would recommend to use https://drupal.org/project/rdf_indexer with https://drupal.org/project/arc2_store instead of the SPARQL module. There is also some documentation on how to set this up at https://drupal.org/node/2028111.
Note that this won't automatically integrate the vocabularies that you may have imported via evoc, but only the RDF from the entities that you created on your site (e.g. nodes).
