Presentation Topics ITIS Overview Technical Aspects Benefits Lessons Learned Future Plans
What is ITIS? An evolving standard reference for taxonomic information on species (biodiversity) A partnership US, Canadian, Mexican governmental groups Non-governmental organizations Developed in collaboration with systematics community and other list keepers
Goal To provide quality taxonomic information about organisms that meets needs of partners and user public Taxonomic coverage: all major groups; focus on North America; world coverage where feasible Service: data quality assurance system for taxonomic identification common reference point for exchange of data capacity building in taxonomy (regional datasets, etc.)
History NODC Taxonomic Code, 7 th ed. – ITIS roots “VIMS Code” or “Taxonomic Code for the Biota of the Chesapeake Bay” – NODC Tax. Code roots 1996 – 7 U.S. federal agencies sign MOU, along with Smithsonian Natural History Museum By 2002 – ITIS North America established; Associate Member GBIF; joined with Species 2000 in “Catalogue of Life”
Partners
How many names? Over 320,000 scientific names 186,000 valid/accepted species names 80,000 additional common names
Data Process & Tools 1. Are my species names in ITIS? 2. Data submission 3. Data development 4. Data load (public site) 5. Data access & delivery - 4 ITIS homepages - master DB resides in US - freely downloadable via FTP; embed ITIS within your system or tools - Develop a script & generate reports at your site - machine-to-machine interoperability - XML output
Required Data Elements Taxonomic Serial Number (TSN) – system assigned; common reference point for exchange of data Scientific Name Author(s) – for records genus and below Rank Usage – current standing Parent Scientific Name – link into hierarchy Associated Accepted Name – synonym link Unacceptability Reason Reference(s) – experts, publications, other sources
Quality Indicators for ITIS Metadata Taxonomic Completeness - complete; partial; unknown Taxonomic Currency - year of revision; unknown Update Date - date record modified Taxonomic Credibility Rating - perceived level of review and accuracy of taxonomic name and attributes
ITIS Uses Examples End-to-end data management support Cataloging applications – Specify, SMMS, mobile computing units Portal applications – BiOSC Gateway ITIS NA Digital library applications – Congo Expedition AMNH Look-up reference Linking point to other nomenclatures & data sources Users link to ITIS
ITIS Uses (cont.) ITIS Compliant Marine Databases Examples
Users Scientists Natural resource managers Publishers Journalists, writers Collections managers, librarians Data managers General public, hobbyists Educators, students Private industry Policy analysts & decision makers
Challenges & Lessons Learned 1. Global vs. Regional Approach 2. Single Name vs. Multiple Classifications 3. Data Quality vs. Data Quantity 4. Current Names vs. All Names 5. Centralized vs. Decentralized
Future Plans ITIS North America – 2003 meeting Integration with other systems Focus on sustainability of ITIS Improved circumscription of taxa Standard for taxonomic data exchange Distributed node architecture; new tools
Distributed Node Approach
Summary ITIS is an evolving standard reference of scientifically credible, quality-controlled taxonomic information on species (biodiversity) ITIS data are used in a variety of applications Referencing biological datasets to ITIS brings significant value to your data - an indicator of QA/QC of species identifications
