  1. Ocean Information TechnologyNew approaches to ocean data management Neville Smith BMRC, Australia COD, Brussells, 25-27 Nov

  2. COD, Brussells, 25-27 Nov The Motivation … The Issues • We have only 5-10% of the needed telemetry capacity. • Data Assembly - no broad agreement on how we ensure coherent, integrated data sets. • Lack of agreement on standards, formats and practices. • Poormodes of data transport, both routinely for operational requirements and for science. • Poor or inappropriate uptake of modern information technology. • No proper assessment of the future need. • …

  3. COD, Brussells, 25-27 Nov Some Foundations • Some good examples of D&IM at work • IODE, JCOMM • OBIS (CoML), Argo DM, ODINAfrica, US IOOS Data plans … • but • poorly integrated • “not invented here” syndrome  many realizations of the same function/form • Too much in-house technology, too little out-sourced functionality • Too little fusion / cross-sector adoption • No / little engagement with scientific community • Innovation not within • …

  4. COD, Brussells, 25-27 Nov Rationale (The Why) • Approach IT as you would a Science Program • Effective telecommunications • Common standards, practices and protocols (metadata management) • Data and product service matched to the participants and users • Innovative data inquiry, access and delivery • Intra-operability and interoperability • …

  5. COD, Brussells, 25-27 Nov The Components … the “How” • Telemetry • Metadata Management • Data assembly, data set integrity, quality control • Data circulation and transport • Archives and archaeology • Applications and user interfaces • Capacity enhancement, training • Governance, oversight, metrics

  6. COD, Brussells, 25-27 Nov 1. Telemetry and Communications … getting the data “in” (instructions out?) • Availability and capability • Bandwidth, 2-way comms, connectivity, … • Requirements for climate, open ocean • Requirements for coastal regions • Polar / remote regionsBandwidth … enabling

  7. COD, Brussells, 25-27 Nov 2. Metadata Management Semantic Metadata • Data about data … • Its environment • Its structure • Its meaning • Keywords • IODE, JCOMM (CBS) and others have made considerable progress Data Syntactic Metadata

  8. COD, Brussells, 25-27 Nov 2. Metadata … • Developing an agreed vocabulary • Perhaps agreeing on a Markup Language: MarineXML or … (e.g., IODE/ICES Project) • An essential element for intra-operability, interoperability and exchange • Non-physical / unconventional: a challenge • Complying with mandated requirements • Complete, consistent, searchable metadata • Keywords, geospatial references • Adopt standardized, shared vocabularies • Developing catalogues • How to do highly effective searches in distributed systems? • How to automate, encourage, …

  9. COD, Brussells, 25-27 Nov 3. Data assembly, quality control, … • More formality, accepted procedures, … • From Level 0 (raw) through Level 3 (analysed) • TOGA, WOCE, JGOFS experience Performance level monitoring

  10. COD, Brussells, 25-27 Nov 3. Datum and Data Set Integrity • Develop methodology for uniquely identifying original data and variants • Argo is being used as one test-bed • Original data given and always retains “tag” • Variations referenced against original • Accreditation • Eg, at level 2: a) no QC; b) auto; c) scientific • Institute A, A+, A++ system, esp. for c) • Recognize value adding • Recognize scientific involvement • Agreed peer-review system • … ?

  11. COD, Brussells, 25-27 Nov 4. Data Circulation and Service • Timeliness, efficiency • Architecture for data/product serving and exchange • Data packets and sets arrive with standard metadata and “tag” • Systems like IDD are used to “push” data to routine users • The sources may be real-time or high-quality delayed-mode • Each ocean data distribution centre has instruction sets for distribution; event driven • Also request-reply (pull) servers • US Data Communicationinitiative …

  12. COD, Brussells, 25-27 Nov US IOOS Model Circuits, data conveyers

  13. COD, Brussells, 25-27 Nov Together  New Functionality • The XML standard (or an equivalent) should ensure all data are properly described / characterized • Some of the needed metacode can be generated automatically • The “tags” allow identification and removal of duplicates • There is immediate identification of non-conforming data insertion • No need to be a major centre to participate (provider or user) • Some traditional data archive (backup) could be automated

  14. COD, Brussells, 25-27 Nov 5. Archives, Centres • Reference other sessions • Centres might specialise in a type of service • Routine versus ad hoc / itinerant • Sophisticated versus non-specialist • Strong link to User Interface theme • Catalogues and Portals: Modern Library • Irreplaceable observations, data products of lasting value and associated metadata preserved in perpetuity • Accessible using standards, keywords • Integrated into real-time and delayed mode data transport mechanism • Data archaeology

  15. COD, Brussells, 25-27 Nov 6. The User Interface • Must make data and information: • Available, usable, accessible, … • Scope • Assess “external” user requirements • “Wizards” to simplify interface • Assess “internal” user requirements • Robust interfaces; guaranteed responses • Several existing innovative client interfaces • Live Access Server and derivatives • GIS Systems; Web Map Server

  16. COD, Brussells, 25-27 Nov E.g., GODAE LAS Product Server: UK http://www.nerc-essc.ac.uk/las Daily 1/9o FOAM N Atlantic data Menu for UK FOAM & POLCOMS data SST for 7 Jun 2002

  17. COD, Brussells, 25-27 Nov 7. Capacity, “education” … • Some of the greatest challenges are in the area of community outreach and organizational behavior rather than in technology! [US IOOS DCS SC] • Challenges • Breaking down traditional barriers • Capacity enhancement: even, “fair” • Adoption and acceptance • Uneven access to technology, people • Reference other presentations

  18. COD, Brussells, 25-27 Nov Conclusion • There is broad consensus on the need to act • We have an outline of the strategy: why, how • Enormous potential to impact science and applications; not discipline bound • Architects and engineers are already busy • Critical that we have broad participation • Starting now • http://ioc.unesco.org/oit
