Data integration and standards at IOC of UNESCO
Edward Vanden Berghe
The organisation
• UNESCO• Intergovernmental Oceanographic
Commission (IOC)• International Oceanographic Data and
Information Exchange (IODE)• Ocean Biogeographic Information
System (OBIS)– Used to be Census of Marine Life– Now IOC under IODE
Networks
• Both IODE and OBIS are global networks
• Main product is data warehouse• Standards of critical importance
– Standards for formats– Standards for content (‘vocabs’)
• Single standard is an illusion– Limited set of standards– Crosswalks between them
International partners
• World Meteorological Organisation– Together JCOMM
• EU– SeaDataNet
• GEO, GOOS, GEO BON– Global observing systems
Standards development
• Several working groups and projects– Metadata
• Based on ISO-19115
– JCOMM• Together with WMO
– Ocean Data Portal• Together with SeaDataNet
– OBIS• Together with GBIF/TDWG
Example: OBIS
• Network of 15 Regional OBIS Nodes, 5 Thematic OBIS Nodes
• All contributing data
• RONs and TONs are aggregators in their own right
• Total of nearly 30M records, from 870 individual data sets
• Integration on a large scale
Example: OBIS standards
• Biogeography: GBIF/TDWG– Darwin Core, Extended to OBIS Schema– ABCD
• Metadata: discovery metadata– Global Change Master Directory – NASA– MEDI – IODE; FGDC – US Gov?
• Taxonomy: World Register of Marine Species (WoRMS) – Contribution to Species 2000 and Catalogue of
Life• Geography
– Polygon sets• EEZs, FAO areas, IHO…
– Gazetteer
OBIS standard output
• CSV and KML• OGC Services
– WMS and WFS– Already consumed by others
• Digital Generic Information Retrieval (DiGIR)
• REST in preparation
• Empower others to use OBIS data
Biology requires more documentation• Taxonomy (‘species’) is an extra
dimension– Taxonomic names are often misspelled
• Many different ways of measuring things– Weight of a jellyfish?
• Species identification labour-intensive and specialists’ work– But automated systems are starting to
appear
