Description

lod_locate attempts to locate triples where uri is the subject URI within the model associated with context. In contrast to lod_fetch and lod_resolve, lod_locate will make no attempt to fetch additional data if no triples where uri is the subject are present in the model.

Return value

Upon success, lod_locate returns a new LODINSTANCE, which should be later freed using lod_instance_destroy.

If an error occurs, or uri was not a subject of any triple in the context's model, lod_locate returns NULL.

Use lod_error to determine whether an error occurred, or whether the subject does not exist in the data. If an error does occur, you can use lod_errmsg to obtain a description of the error condition.
