PSU Knowledge Bank Workflow
Workflow
Workflow System
PSUKB develops its DSpace program based on the Open Archival Information System (OAIS) model to provide data storage services to Prince of Songkla University students and personnel.
The main task of the ingest component of an OAIS is to obtain a Submission Information Package (SIP) and change it into an AIP appropriate for inclusion in archival storage. Figure depicts the DSpace ingest process. Currently, DSpace supports two methods of ingest. The first method is a batch item importer. A simple external SIP format has been defined for this importer, in which the metadata (Dublin Core) is saved in an XML file in a directory with the associated content files. The batch importer converts these external SIPs into DSpace SIPs, stored in the DSpace database and Bitstream store. It must be copied to a temporary directory on the DSpace server, and the batch importer tool must run via a remote shell to import content. DSpace also features a web-based submission user interface, the second method. A submitter (producer using OAIS terminology) fills out relevant metadata fields and uploads the content files to DSpace utilizing this interface. This information is used by the submission UI to create a DSpace SIP in the database and Bitstream store. Once the SIP has been created in DSpace, the workflow linked with the target collection is initiated. This corresponds to the ‘quality assurance’ function in the OAIS model.
The workflow system in DSpace is quite simple, with three possible workflow roles: Reviewers can accept or reject the submission; approvers can accept or reject the submission and edit the item's metadata; and Editors can edit the submission's metadata but may not reject it. Once they have completed any necessary edits, they commit the submission to the archive.
DSpace can currently disseminate three sorts of DIP: Community, collection, and item record web pages, individual Bitstreams via HTTP, and a file system-based format that includes metadata in an XML file and composite Bitstreams. DSpace already provides a variety of discovery mechanisms: Handle Resolution, Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), Search and Browse, Subscriptions, and OpenURLs

PSU Knowledge Bank has set hierarchical data structure into three levels as follows.
1) Community is faculty or institution
2) Sub-Community is a program or department
3) Collection is a type of publication, such as a thesis, dissertation, research report, book, or article. Which archives data files and metadata. The data structure is shown in the figure.
