LTER Data Management Margaret O’Brien Santa Barbara Coastal Long Term Ecological Research (LTER) Project Santa Barbara Channel Biodiversity Observation Network 2014-04-24
LTER Network http://LTERnet.edu • 25 sites, funded by NSF (1980) • Independent research, locally driven • Primary production • Populations • Ecosystem cycling • Organic • Inorganic (nutrients) • Disturbance • Considerable leveraging • Partnerships • USDA, USFS, • Integrated data management http://iLTERnet.edu
LTER Data Management Cross-site comparisons began in the 1990s Developed XML-based data sharing mechanism EML released in 2003 • Sites are the experts for their own data, and should work with the systems and partnerships that are available • Sites collaborate as appropriate within the LTER to develop the software they need, and create economy of scale by converging practices and mechanisms • Network sets goals and provides a collaborative atmosphere, but does not dictate mechanisms
LTER Data Management Today • Active DM committee • “Best Practice” docs • ESIP member • Central data catalog • DOI assignment • Data package checking • Automated code generation • R • Matlab • SAS • Federation
EML Overview • Related specifications • FGDC • ISO-19115 • Darwin Core (DwC) • Communities • OBIS, GBIF (Darwin Core Archive) • TDWG • Features • Rich structural metadataallows automated ingestion • Active development community

Santa Barbara Coastal LTER IMS Collection to Distribution • Established protocols for handling and processing • RDBMS -> XML • Community standards and expertise • Structural quality control for data tables and metadata • Machine-readable data • Federation Field Data collection protocols Data Package Design EML Metadata Export Data Package Checking Servers Backup& processing
Santa Barbara Channel BON IMS • Adopted community protocols and standards • Per LTER • RDBMS -> XML • Structural quality control • Local catalog • TBD • Federation mechanism DataONE Member Node? Servers Integrate ingested & de novo data Data Package Design EML Metadata Export Data Package Checking
Possible Next Steps • Outline potential strategies for posting data • Examine repositories • Exchange specification(s) • Multiple partners & endpoints? • Consider impact on local groups • Alternatives • Submit once to federated repository for broad retrieval • Begin developing data quality requirements • Examine available tools and vocabularies • Define use cases
