GBIF - A global discovery point for biodiversity data

GBIF: Extend global discovery to taxonomic data
![Page 4: GLOBAL BIODIVERSITY](https://reader035.vdocument.in/reader035/viewer/2022062410/5681570d550346895dc4ad4f/html5/thumbnails/4.jpg)
Enabling global discovery: Objectives
• Develop capacity to document and publish taxonomic data– A simple exchange format– Suite of publication tools
• Promote the publication of taxonomic data in a common format
• Build and maintain an index of published checklists
• Build services on this index that address user needs in the GBIF network
![Page 5: GLOBAL BIODIVERSITY](https://reader035.vdocument.in/reader035/viewer/2022062410/5681570d550346895dc4ad4f/html5/thumbnails/5.jpg)
Enabling global discovery: Outcomes
• Embed taxonomy into large-scale biodiversity data/info. management– Improved Interoperability among resources– Improved Precision and Recall within resources
• Increase efficiencies in taxon-related linking, mapping, data-mining, and data management
• Increased recognition of the value and relevance of taxonomy within all biodiversity information interchange (large and small)

Roadmap
• Evaluation and testing and refinement Q4 2010
• Consolidate docs and publishing for ver. 1 Simple Exchange Format using DWC-A
• Target current taxonomic data export publishers– Small grants to pilot DWC-A exports
• Seed funds to GBIF Nodes– Publish regional and thematic species checklists– Evaluate 1.0 extensions and vocabularies
