  1. PLANETS, OPF & SCAPE • A summary of the tools from these preservation projects, and where their development is heading www.openplanetsfoundation.org

  2. PLANETS • A big project to build digital preservation tools... www.openplanetsfoundation.org

  3. OPF’s Challenge • The Open Planets Foundation was set up to sustain the PLANETS outputs into the future. • But the tools are • Numerous, often complex, & of mixed quality/maturity • Require complex technology stacks (JEE) • So, how do we make the code sustainable? • Selection, modularisation, simplification • Aim for a flexible suite of modular tools, rather than a monolithic system www.openplanetsfoundation.org

  4. SCAPE • http://www.scape-project.eu/ • Many PLANETS partners • Including OPF • Many new partners too • Driven by data • Web archiving, science data, large-scale • Cluster computing for scale • Based on the HADOOP platform www.openplanetsfoundation.org

  5. PLATO www.openplanetsfoundation.org

  6. The PLANETS Testbed www.openplanetsfoundation.org

  7. The PLANETS Testbed:Too Many Good Ideas In One Place • Designing experiments • Web GUI for complex workflows • Running experiments • All services hosted centrally, plus test corpora • Analysing the results • Per-experiment automated & manual analysis • Multi-experiment aggregation & data mining • Sharing all of the above www.openplanetsfoundation.org

  8. Re-imagining The PLANETS Testbed:A Modular Approach • Use separate tools in each role • Experiment Design • Execution • Analysis • Publish results from each • Loosely coupled instead of all-in-one • i.e. sharing is built into the design www.openplanetsfoundation.org

  9. Experiment Design: SCAPE Workflows In Taverna • As part of SCAPE www.openplanetsfoundation.org

  10. Experiment Design Support: SCAPE Service Registry www.openplanetsfoundation.org

  11. Experiment Design Support:OPF Shared Test Corpora • Simple collections accessed over HTTP • No special browser software required • Publicly hosted by HATII • May also be mirrored by OPF members • Stabilise corpora from Planets • Adsorb corpora from SCAPE & elsewhere • Look for Open Source CMS/Annotation tools • Layer on top of HTTP collections www.openplanetsfoundation.org

  12. Experiment Design Support:Sharing & Publishing Via myExperiment www.openplanetsfoundation.org

  13. Experiment Execution Support:SCAPE’s Lightweight Tool Wrapping • PIT: Preservation-action Invocation Tool • Uses XML ‘tool specification’ documents that describe preservation actions • Command-line templates, Java classes, PLANETS/SCAPE web services, etc • Built to be shared • Can be published via, e.g. myExperiment • Should lead to more reproducible results • Re-using PLANETS interoperability code www.openplanetsfoundation.org

  14. Experiment Execution:Multi-platform Tool & Workflow Invocation • Shared tool specifications make multi-platform execution easier • From the command line • From within Taverna • From the SCAPE cluster platform • From a simplified web interface • Run local-first, remote/service as needed • Collect results in a standard form, using Testbed code www.openplanetsfoundation.org

  15. Experiment Execution:Publishing Experimental Results Via REF • OPF Results Evaluation Framework: REF • Hard-coded experiments of common interest • Can run the experiment automatically • Publishes results as linked data • http://data.openplanetsfoundation.org/ref/extension/ • Built by Dave Tarrant, based on P2 format registry • Will come up again in the Identification session • SCAPE aims to publish much more data www.openplanetsfoundation.org

  16. Analysing Results:Linked Data & Future Plans • REF allows data to be inspected • Concentrating on collecting data at present • Will expose SPARQL endpoint for data queries • Analysis, visualisation can be build upon that • Please add analysis Issues for your Datasets and preservation processes to the wiki! • e.g. what graphs and statistics would be useful? www.openplanetsfoundation.org

  17. Summary • PLATO • SCAPE will add Preservation Watch & more • The PLANETS Testbed • Re-imagined as a gateway to a complementary suite of preservation tools and data services • SCAPE leveraging work from Taverna, IMPACT • Development driven by user needs • SCAPE Scenarios, AQuA/Hackathon Issues www.openplanetsfoundation.org
