Richard White’s interests
• Design and construction of database systems to deliver biodiversity data
• Methods for making these systems – interoperable with other systems– adaptable for multiple uses– capable of following concept changes
• deducing and maintaining information on changes
• (Extracting numerical information from images, e.g. in “Morphidas” project, not described here)

Premise
• Bioinformaticians want to use information about the species whose genetic material is being studied to understand their development
• Biodiversity scientists (including taxonomists, ecologists, etc.) want to use molecular data to enhance their classifications, phylogenies and models

Biodiversity informatics
Therefore
• Bioinformatic and biodiversity data need to be linked together in many analyses
• Links often involve the species name as the key linking element
5Cardiff School of Computer Science & Informatics
Species naming in a nutshell (Corylus avellana L.)
• Common (vernacular) names• Latin descriptive phrases• Linnaeus: binomial nomenclature• Adanson: rules for precedence etc. • Accepted names and synonyms• Checklists (e.g. the Catalogue of Life …)• Data (in different formats, e.g. Buffie …) is
usually linked to species names• Taxon concepts (including species and higher
taxa such as genera, families, etc.)• Tracking changes in taxon concepts …

Species 2000 & ITIS
• International programme to assemble data from “Global Species Databases” (GSDs) and deliver the Catalogue of Life (CoL)
• Authoritative up-to-date checklist of all the world’s species (1.3 out of 1.8m)
• Reference list of taxon concepts (with unique identifiers) to aid indexing and cross-referencing of species data sources
• Available on DVD, through the Web (www.sp2000.org) and by using electronic (“web”) services

The Catalogue of Life
8Cardiff School of Computer Science & Informatics
4D4Life project
• “Distributed Dynamic Diversity Databases for Life”, EU project 2009 – 2012
• Carry the Catalogue of Life forward with improved sustainable infrastructure
• In COMSC we are designing a new architecture and will deliver a working prototype
• Service-oriented, re-usable components
9Cardiff School of Computer Science & Informatics
Re-usable components
1. GSD editors create a data resource “GSD1”
2. CoL partners create the Catalogue of Life from such resources
3. A user creates a new product using the Catalogue of Life

Interoperability
• Catalogue of Life– GSDs are heterogeneous in
• Content
• Access methods
• More generally– Multiple data representations & exchange
formats– Changing concepts of taxa (and geography)
11Cardiff School of Computer Science & Informatics
ENBI project and BUFFIE
• “European Network for Biodiversity Information”, EU project 2003-2006
• Mostly reporting on standards, practices and recommendations
• In COMSC, R. Sundaravadivelu developed a prototype interoperability demonstrator (BUFFIE, “Biodiversity Users Framework For Information Exchange”)
• Accepts data sources using different protocols and XML formats
• Provides a merged response in an XML format and protocol of the user’s choice

THIS SLIDE INTENTIONALLY LEFT NOT QUITE BLANK

A world of resources
• Imagine a digital world full of biodiversity data and analytical resources like these, just as there is in bioinformatics
• How will users be able to find out what resources there are and how to use them in combination to answer scientific questions?

The cross-mapping problem
Taxonomy 1
Vicia faba
Caesalpinia crista L.
Taxonomy 2
Faba faba
Caesalpinia crista L.
Caesalpinia bonduc (L.) Roxb.

Constraints and checklists
• (From Litchi 1)
• “A full name which is not a pro-parte name may not appear as both an accepted name and a synonym in the same checklist”
17Cardiff School of Computer Science & Informatics
Persistent identifiers and change
In i4Life we need to
• Use persistent identifiers for taxon concepts– (started in TDWG-TIP project)
• Link taxonomies and track change– create and maintain “cross-maps”
18Cardiff School of Computer Science & Informatics
Joining things up: workflow systems
19Cardiff School of Computer Science & Informatics
20Cardiff School of Computer Science & Informatics
Workflow problems addressed
• Incorporation of biodiversity services in workflows (BiodiversityWorld)
• Authentication in a workflow environment (ASMIMA)
• Rich annotation of services; discovery (Ewen Orme’s PhD)
• Knowledge-based assistance for workflow creators (Russell McIver’s PhD)
• Improving the User Experience (ACJ’s main contribution to BioVeL proposal)
21Cardiff School of Computer Science & Informatics
Andrew Jones’ interests
• Naming & concepts– Accurately identifying concepts– Tracking change
• Making scientific workflow systems usable by non-computer scientists– Hiding “programming” complexity– Helping to find resources & build workflows
• Environments to support collaborative scientific research– E.g. “doing” taxonomy
22Cardiff School of Computer Science & Informatics
Future projects
• We research solutions for data-handling problems faced by biologists and bioinformaticians
