Abstract
The Sapienza Digital Library collects digital resources from the different University's Organizations representing the multidisciplinary Sapienza University's community. The poster presents the pre-ingestion process for creating and aggregating digital resources, under the Organizational Collection conceptualization. The pre-ingestion building process had allowed to automatically provide information about the resources' custody from the origination, until their creation as OAIS Submission Information Package. Whatever system able to provide archival, preservation or dissemination services, could potentially use it, maintaining provenance information.
