The document describes sample patient data provided in N3 and XML formats. It also describes an ontology defining classes like PatientData and properties like height and mass. Additionally, it provides a SPARQL query and discusses how a SADI service can calculate BMI from untyped input data by using description logic reasoning to discover the data types.

1. SAMPLE DATA as N3:
@prefix mged: <http://mged.sourceforge.net/ontologies/MGEDOntology.owl#> .
@prefix demo: <http://linkeddata.systems/ontologies/SADITutorial.owl#> .
@prefix example: <http://example.org/patients#> .
example:Mark
a demo:PatientData;
mged:has_height "1.93";
demo:has_mass "96".
example:Jerven
a demo:PatientData;
mged:has_height "2.00";
demo:has_mass "85".
SAMPLE DATA as XML:

2. -- note that, because of annoying peculiarities in how Chrome handles
certain XML content-types, it is necessary (for humans) to view this in
Firefox, so that the XSLT transform is triggered correctly… Grrrrrr
Execute from command line:
curl -H 'Content-Type: text/rdf+n3' -H 'Accept: text/rdf+n3' -i --data-binary

Register the service
http://sadiframework.org/registry/register/
(there is a REST interface you can use for bulk registrations, but you
don’t get a lot of feedback on failure…)

SPARQL Query for SHARE (http://dev.biordf.net/cardioSHARE/)
SELECT * FROM <http://linkeddata.systems/sampledata.rdf>
WHERE {
?s <http://sadiframework.org/examples/bmi.owl#BMI> ?val
}
Have a look at this:
http://linkeddata.systems/sampledata_untyped.rdf
Use that in your “FROM” clause… SHARE is using DL reasoning to
automatically discover and rdf:type the input data for the service!

4. Dynamic match-making between “generic” RDF data and appropriate service
interfaces.
Also look at this:
curl -H 'Content-Type: text/rdf+n3' -H 'Accept: application/n-quads' -i --data-binary
