Project Overview Marco Schaerf

• Offer researchers and students of Sapienza University the

opportunity to use digital materials owned and produced by

Sapienza

• Building future-oriented infrastructure, interconnected with the

most important European and international repositories for

the cataloging, preservation and use of the digital heritage of

Sapienza University

Vision

• Necessity of a system that can handle very heterogeneous data: – Digitalized books (old or not)

– Collections of images, videos, music, 3D models

– Scientific publications and scientific datasets

– E-learning materials, ebooks, born-digital material

– Special collections (eg exacvations archives ...)

– Connected with archive OPAC and digital subscriptions

• Need to include material of a different type: – library, museum, archives, scientific, educational .....

• Need to ensure the long-term investment: – long-term Digital preservation

Requirements

• No suitable existing system

• Decision to develop a new system with: – Compatibility with advanced classification standards

– Based on open-source platforms and open-access

– Integrates with leading national and international repository (Internet Cultural, Europeana, ...) and with similar initiatives from other universities

– Simple to use, extensible and easily maintainable

• Development Partner – Cineca (www.cineca.it)

Output of the Analysis

• Identification of the available digital material • Analysis and treatment of the material (metadata and digital objects) • Production of tools for the resources to be inserted in the system • Resource Modeling (characteristics, internal structures ..) • Modeling Infrastructure metadata conforms to international standards

for digital libraries

Workflow and Organization

SDL System

A. Collection of materials: digital objects and descriptions B. Analysis of materials: how they are organized and named objects and how the

descriptions can be adapted to the MODS profile C. Mappig descriptions to MODS D. Dumbing down towards DC / ESE / LIDO (Europeana and other aggregators) E. Rename and acquisition of information of individual objects F. Encoding and enrichment of the administrative / technical / descriptive / preservation

metadata G. Construction of the METS H. Validation, standards Compliance Monitoring and specifications for SDL I. packing and compression of individual Submission Information Package (SIP)

Output of the Analysis

The core descriptive metadata is the MODS, all the descriptions of the resources are mapped in MODS and the corresponding information encoded automatically in other less granular descriptive standards (DC / ESE / LIDO standard of Europeana). SDL interface services (browsing, advanced search, …) are built on top of the modeling of resources and collections encoded with the MODS standard

Output of the Analysis

Advanced and more detailed information is collected using the METS standard. The flexibility of metadata together with the atomization of the individual objects facilitates the reuse of digital content in (unpredictable) future contexts

Digital Library Services

Digital Library

MediaMosa – REST services

• MediaMosa offers over 150 REST-calls divided in services for:

• Play Video, Authentication,

Authorization, Upload, Transcoding

(FFmpeg), Media Management, Search,

Jobs servers, Metadata and OAI-PMH,

Notification, Logging and Statistic

• A typical integration workflow:

1. Upload of the original mediafile (+ transcoding profiles selection)

2. Creation of a new MM asset 3. Creation of transcoding Jobs in Job

server’s queue

4. Store of transcoded mediafiles 5. Streaming delivery based on transcoding

profiles (multi-protocol, multi-profile)

Digital Library

Ongoing developments

and topics of interest

• Auth/Authz (Portal Roles Filter, Shibboleth, Web Services, Fesl, XACML)

• Full text and MD indexing via Lucine/Solr/Tika

• Social features: Linking, Sharing, Commenting, Rating at Repo level

• Preservation (procedures implementation, best practices adoption,

trusted repo certification)

• Persistent Identifiers services integration (both on ingestion and

backoffice, multiprovider)

• Multilingual version

• Semantic Web, linked data, conceptualization

• New interfaces for content, relationships, data visualization (HTML5,

RDF, Graphs)

• e-learning integration (Videolectures, already described using METS -

LOM)

• e-book (ePub)

Digital Library

Conclusions and Challenges

• Online on May 23rd, after the official presentation (jointly with Cineca)

• Developed (together with Cineca) a comprehensive system to store,

preserve and access the digital material of Sapienza University

• Based on Open Standards and Tools

• State of the art methodologies and technologies, on a par with much

bigger projects

• Fully interoperable with existing systems

CHALLENGES

• Populate the Digital Library (Digitizing is expensive)

• Promote its adoption in our community and in other universities

• Make it usable yet powerful for a wide variety of users
