Associating named query to a REST endpoint

[Bruno Dias]

Greetings!

This is just a feature request/suggestion: exposed named queries in REST endpoints, for a given namespace. The parameters in the querystring (to make it simpler) could be mapped to some of the variables in the query.

This would help A LOT in the integration with libraries like backbone.js. And yes, of course there is still the issue with security. It is just an idea. :)

Bruno,

Thank you. I've created a ticket:
https://jira.blazegraph.com/browse/BLZG-1674. Can you update it with a
couple of scenarios / examples you'd like to see?

Thanks, --Brad

The ticket does not exist, Brad.

Use case 1
You want to do something like the Last.fm scrobbling. To create a scrobbling event, you use the following query:

PREFIX mo: <http://purl.org/ontology/mo/>
PREFIX co: <http://purl.org/ontology/co/core#>
PREFIX event: <http://purl.org/NET/c4dm/event.owl#> .
PREFIX foaf: <http://xmlns.com/foaf/0.1/> .

INSERT {
    ?scrobble a co:ScrobbleEvent .
    ?scrobble event:agent ?user . 
    ?scrobble co:scrobble_object ?music . 
}
WHERE {
    ?music a mo:MusicalExpression . 
    ?user a foaf:Agent . 
    BIND(UUID() AS ?scrobble) 
}

Then, you perform a POST to http://www.example.com:9999/bigdata/namespace/kb/services/scrobbling, with the following parameters in the body of the request: user=mxc:u1, music=mxc:m100. As a result, it should/could return the new UUID.

There are more use cases in my head but I'm having a busy day to write the remaining ones. Tomorrow (if I remember to), I will add with new ones.

Bruno,

Strange. I updated the ticket with your example:
https://jira.blazegraph.com/browse/BLZG-1674.

Thanks, --Brad
