Presentation Transcript

1. Long-term preservation in the cloud LTP-SaaS Dr. Claus-Peter Klas Prof. Matthias Hemmje

2. Data Management Life Cycle and Roles Reuse (Consumer , Producer, Archivist) Creation (Producer, Archivist, Consumer) Reuse Creation Adoption Assembly Assembl y (Producer, Archivist) Adoption (Archivist, Consumer) Pre-Ingest Post-Access Archival Ingest Access Archival (Archivist)

3. General Architecture Community Based Data Management Re-Use Ingest Collaborative Task-based Search & Access User OAIS Compliant Archive Interfaces Web Mobile Index Search Access

4. General Architecture Data Management Preservation Aware and Provenance URI/URN SIP Metadata Full-text Multi-Media Provenance OAIS Compliant Archive AIP User Collaborative Task-based Search & Access URI/URN Thumbnail Interfaces Web Mobile DIP

5. Preservation Aware Data Management Data management: Dropbox equivalent online storage for direct and dynamic data handling during information creation time Should be preservation aware, meaning gathering basic, dublin core like, metadata about the current task, project, persons etc. Gathering provenance information about access, re-use, transformations

6. OAIS Complaint Archive Ingest: Packaging Tool (SciDIP) PG Prototyp LTP System Cologne

7. Collaborative Task-based Search & Access ElasticSearch Server for Searching Metadata Provenance Full-Text Pictures Video REST Interface for UI REST Access Interface to index from Archive

8. User Interface Vaadin based Web Interface Mobile Interface (maybe also Vaadin)

9. Compliance with EGI Cloud Services All LTP services will run on dedicated virtual machines EGI monitoring service will supervision the virtual machines (VO) Furthermore monitoring services should monitor services in virtual machines, e.g. at least for a life sign aka ping Potential response: Notification of administrator Automatic recovery, replacement or extension of virtual machine EGI backup service to store the virtual machines, setups, etc. (Check by EGI: Application DB) EGI User handling and authorization and single point of authorization (Certificate, not Facebook account Roles: Curator Certificate Consumer: Open Access (Robot Certificate: Service needs to be saved) Workflows on dynamic extensions of storage and CPU based on service level agreements and monetary resources Easy and flexible billing

10. Starting Requirements 1-3 VMWares: Standard Ubuntu LTS with 1 CPU & 300GB Diskspace & 4GB RAM Start: 1 TB Shared Data Storage
