  1. Building the LTER Network Information System

  2. NIS History, Then and Now

  3. NIS Mission Statement “… to promote advances in collaborative and synthetic ecological science at multiple temporal and spatial scales by providing the information management and technology infrastructure to increase: • availability and quality of data from LTER sites • timeliness and number of LTER derived data products • knowledge generated from the synthesis of LTER data” Bottom line: Make LTER data available in a consistent format through a single web portal Provide derived and value-added data for community use Provide tools for data discovery and evaluation

  4. NIS Ingredients • Site collected data and metadata • Middleware (software) developed at LNO or integrated from other sources (e.g., sites, open source projects) • Internal value-adding applications leading to derived data and metadata products • Data modules from other LTER science initiatives (e.g., ClimDB/HydroDB, EcoTrends) • External value-adding applications

  5. LTER Network Information System Site data and metadata NIS middleware (PASTA) External value adding applications

  6. LTER Network Information System Middleware (PASTA)

  7. LNO Operational Plan • Spells out operational steps to develop NIS • Formalizes multiple pathways for communication and feedback • Establishes a timeline involving multiple development cycles with frequent releases • Emphasizes engagement by LTER scientists

  8. NIS Development Timeline Operational Prototype • Complete prototype but only partial functionality Start of Development Production Deployment • Development will be both iterative and incremental • Full features Incremental release Transition to maintenance

  9. Completing the NIS requires involvement from a broad cross-section of LTER members • Tiger Teams – to provide community dialogue and rapid feedback as part of specific component development teams • Requests for Comments – to receive thoughtful written comments from individuals or groups in the stakeholder community • Focus Groups - to get focused feedback on specific components • Surveys – to assess bi-directional communication effectiveness • IM Working Groups – will provide design, specification, and development on specific tasks and sub-components • Research Working Groups – will provide design and specification on derived data products • NISAC – will provide advise and evaluation on the NIS • LTER Executive Board – will provide endorsement and evaluation

  10. Tiger Teams “Referring to a team set up solely in response to a specific situation or problem, without considering any wider or longer-term issues.” - Wikipedia • Roles & Responsibilities • 2-3 individuals • Information Managers • Scientists • Graduate Students • Scope of work • Direct input to requirements and design • Intermediate and final acceptance testing of software • Commitment • 4-8 months • A couple of hours per week • Rapid feedback www.maxim.art.prv.pl
