Title: LIROLEM – Service Usage Model
Section: Structure & Arrangement
Page: 6
Summary of contents:
(section reproduced)
“Services: Security, user management, submission, object store, metadata management, search, transcoding, rights management, dissemination and reporting.
Data Sources: User profile information; data object & object representation information (SIP); provenance, context, reference and fixity information (AIP); METS, IMS Packages, IEEE LOM, PBCore, Dublin Core/OAI-PMH (DIP). For SIP, AIP & DIP, see OAIS Reference Model.
Co-ordination:
The Security service authenticates and authorises the user to use the upload, metadata management, search, transcode and download services.
The User Management service creates, modifies and removes users and their permissions.
The Submission service permits the ingest of data objects and and object representation information (SIP) to the repository.
The Object Store service tracks data objects being submitted and disseminated from the repository.
The Metadata Management service, creates, modifies, verifies and removes all content metadata (descriptive, administrative and technical) in the repository, as well as private user metadata (notes, bookmarks) and shared user metadata (tags, comments). Metadata is linked to objects (items, sets, resources), Licences and users. Provenance, context, reference and fixity information (AIP) is comnpleted for the data object and validated.
The Search service allows a user to search data managed by the metadata management service, according to permissions granted by the user management service. The search service returns and displays search results drawing from the object store service and metadata management service.
The Transcoding service converts data objects from the source format to another format. This occurs at submission time to create preview thumbnails of images and clips of video and audio and also as requested by the user prior to dissemination. Transcoding is performed according to rights applied to the data object.
The Rights Management service requires the application of terms and conditions (a ‘Licence’) to the data object.
The Dissemination service permits the download of transcoded data objects and selected metadata (DIP) according to the Licence applied to the data object.
The Reporting service permits the audit and reporting of transactions by each of the above services.”
Comments:
this section presents the key service arrangement part of the SUM. this outlines the arrangement of software services and standards LIROLEM used to support the management and use of multimedia resources. As such it provides a point of reference for other software development and delineates what standards the development/ implementation used.
it would have been helpful if the SUM had explicitly linked standards with specific service arrangements – however the connections will, in general, be deducible.
