- rdf_attach_library(+Source)
 - Attach manifest from Source. Source is one of
- URL
 - Load single manifest from this URL
 - File
 - Load single manifest from this file
 - Directory
 - Scan all subdirectories and load all 
Manifest.ttlorManifest.rdffound. If Directory is a path-alias (e.g.,ontology(.)), all referenced directories are scanned for manifest files. 
Encountered namespaces are registered using rdf_register_ns/2. Encountered ontologies are added to the index. If a manifest was already loaded it will be reloaded if the modification time has changed.
