  1. LTER 1990-1999Moving from Data to Information Management John Porter

  2. The World in 1989 • All data sharing between LTER sites is on a case-by-case basis – no policies • Site data catalogs are not available • Most researchers don’t use electronic mail • Many mail systems won’t talk to one another • An “online system” is a “bulletin board” type system that requires a modem • There are no standards for metadata content or structure

  3. The World in 1999 • LTER sites share most data within 2 years of collection • There is a centralized system for searching for LTER Datasets • LTER Climate, Personnel and Bibliographic Databases are fully operational • Electronic communication (e.g., email) is ubiquitous • There are published standards for Metadata content

  4. How did we get there? A timeline for progress

  5. 1990 (Snowbird) • “LTER Core Dataset Catalog” published • “Guidelines for Site Data Policies” produced at 1990 DM and All-Scientists’ Meeting (“Proprietary Issues”) • LTER Email forwarding system active • (e.g., jhp7e@virginia.edu -> jporter@lternet.edu ) • Links different mail systems (e.g. forest service) • LTER “Connectivity” report submitted to NSF

  6. 1991 (San Antonio) • Working group discussed “Interactive Data Access” systems

  7. 1992(Honolulu) • Mention of “Gopher” online systems at DM meeting • All-Site Bibliography proposed (but not funded) • 10-year plan developed • Demonstration of structured metadata using “Attribute-Value” syntax • Started the chain of development on metadata to support automated processing

  8. 1992 A test shell-script at the VCR/LTER automatically generated a SPSS job based on metadata in the “attribute-value format” from the CPR (now SGS) LTER The idea of using a common format for metadata exchange was an important outgrowth from the 1992 meeting that ultimately led to EML 2.0 a decade later.

  9. 1993 (Madison) • Symposium “Environmental Information Management and Analysis: Ecosystem to Biosphere Scales”, May 20-22, 1993, in Albuquerque – Led to 1994 book • Prototype All-Site Bibliography database developed • 8 sites had online Gopher/WAIS systems • “Site Review Tips” • precursor to site review guidelines • Oct. 1993 – initial distribution of WWW “kit” for LTER sites

  10. 1994 (Seattle) • Use of WWW servers at LTER sites grows dramatically • (first use of URL’s in meeting report) • Expanded LTER DM Meeting – bought in other groups for joint meeting • LTER Coordinating Committee mandates that each site share at least one dataset online • “LTER Data & Information System” (later became “Network Information System)” proposed • LTER Minimum Metadata Content Standard formalized

  11. 1994 - Metadata Content

  12. 1995 (Snowbird) • Strategic Vision Statement • First use of “Information Management” instead of “Data Management” • Continued design of “NIS” • “Dream” Information system • Continued to formalize governance – “Data Management Task Force” precursor to IMEXEC • First election • Most LTER sites now have online servers • DataBits starts publication hiatus 

  13. 1996 – Archibald Biological Sta.

  14. http://www.vcrlter.virginia.edu/nis/im97/rogues.html

  15. 1996 (Lake Placid, FL) • X-roots Climate Data workshop • May 1996 (seed for CLIMDB) • V1.0 ClimDB data exchange format developed • Mandate to share all data within 2-years of collection • Strategy developed for Data-Table-of-Contents (DTOC) data catalog • Survey of Site Software & Hardware • Participation in Eco-Informa ’96 conference • LNO move from Seattle starts

  16. 1997 (Albuquerque) • FLED committee produces Ecological Metadata paper in Ecological Applications • Prototype CLIMDB & DTOC operational • Revision of LTER Network Data Policy • DIMES workshop

  17. Data & Information Management for the Ecological Sciences (DIMES) workshop – 1997 – Albuquerque, NM http://ecoinformatics.org/pubs/guide/frame.htm Also was important precursor to 2000 book

  18. 1998 - Baltimore

  19. 1998 (Baltimore) • LNO completes move from Seattle • New Sheriff in Town • Presentation on XML

  20. 1998 • Operational: • Personnel • DTOC • CLIMDB • Revision: • Bibliography • Prototype: • SiteDB • Planned: • NitrogenDB

  21. 1999 (Spokane) • Knowledge Networking for Biodiversity Project funded • SiteDB and ClimDB move to LNO • DataBits publication resumes • EML 1.4 standard published • Active Metadata working groups

  22. Lessons Learned • “If at first you don’t succeed, try, try again” • Initial 1991 Climate Database never really got off the ground, but subsequent efforts have been highly successful • SiteDB had several different homes • “Many hands make light work” • CLIMDB – X-roots -> Climate Committee -> NTL -> LNO -> AND • SiteDB – PAL/BNZ -> LNO

  23. THANKS: People that left the LTER Network 1990-1999 • Bill Michener – Core Datasets Catalog, DIMES • Rudolf Nottrott – Email forwarding system, LTER Personnel Database, Core Datasets Catalog • Caroline Bledsoe – All-Site Bibliography v 1.0, X-Roots • Harvey Chin – All-Site Bibliography v.1.0, setup kits for WWW servers • Tom Kirchner – Attribute-Value format • And MANY more

  24. THANKS – 8/12/1999
