1. PESI Pan-European Species-directories Infrastructure European GBIF nodes Meeting — Paris, 4 April 2011 Walter Berendsohn (based on presentation by Yde de Jong)

2. PESI project Aim: Creating a Pan-European taxonomic backbone (an All-Species Checklist of Europe) Based on the existing 3 large European databases: + European Fungi (Index Fungorum) & Algae (Algaebase) 2.64 million Euro, 40 partners, May 2008 - April 2011 Fauna Europaea European animal species Terrestrial & freshwater European Register of Marine Species European marine species Euro+Med PlantBase European plant species Terrestrial & freshwater

3. PESI in the context of other EU projects (FP 4) (FP 5) (FP 6)(FP 7) Digitisation & Infrastructures Integration & e-Science Networks of Excellence

4. Sustaining Pan-European checklists - issues Sustaining the expert networks Sustaining the database systems Sustaining the maintenance (updating) tools & functions Sustaining the interoperability (e.g. Global Name Architecture) Sustaining the data dissemination (webportal) Sustaining the data verification (quality control / validation) Sustaining the implementation of European taxonomic standards SMEBD Host Institutions EDIT Platform for Cybertaxonomy Focal Networks VLIZ / Hosts (LifeWatch?) *4Life projects (LifeWatch?)

10. PESI Validation Tools: Taxon Match Tool - 1 http://www.eu-nomen.eu/portal/taxamatch.php TAXAMATCH fuzzy matching algorithm by Tony Rees, PHP/MySql port of TAXAMATCH by Michael Giddens, Scientific Names Parser by Dmitry Mozzherin

11. 1.Exact match test 2.Phonetic match test 3.Custom Modified Damerau-Levenshtein Distance (MDLD) 4.Modified n-gram comparison of author names and dates, including known abbreviations PESI validation tools: Taxon Match Tool - 2 Mapping between two taxon names lists (exact and fussy)

14. What are the properties of a Taxonomic Backbone –connecting different uses of the same name for multiple classifications –persistent name-name relationships of species names Optimise data sharing / interoperability –Linked Data mark-up –persistent identifiers: globally unique IDs (GUIDs, LSIDs) –DarwinCore Archive format for transport Standardised ontologies / vocabularies –consensus classification –consensus distribution and occurence scheme Conceptual integration
