To get an idea of how it works, try the following iTQL query, which asks for information about all Service Definition objects in the repository:
| Code Block |
|---|
| sql |
|---|
| sql |
|---|
| borderStyle | solidsql |
|---|
|
select $object $modified from <#ri>
where $object <fedora-model:hasModel> <info:fedora/fedora-system:ServiceDefinition-3.0>
and $object <fedora-view:lastModifiedDate> $modified
|
...
In this example, we'll show how to extract a subgraph from the resource index using iTQL. Enter the following query text:
| Code Block |
|---|
| sql |
|---|
| sql |
|---|
| borderStyle | solidsql |
|---|
|
select $a $r $b from <#ri>
where $a <fedora-model:hasModel> <info:fedora/fedora-system:FedoraObject-3.0>
and $a $r $b
and $b <fedora-model:hasModel> <info:fedora/fedora-system:FedoraObject-3.0>
