3The EEA's Mission
- ... is to delivertimely, targeted, relevant
and reliable information to policy-makers and
the public for the development and implementation
of sound environmental policies in the European
Union and other EEA member countries. - http//www.eea.eu.int/
4EEA Origin and Development
- In June 1990, the Council of Ministers adopted
the regulation which forms the legal basis of the
Agency - Council Regulation 1210/1990/EEC, amended
byCouncil Regulation 933/1999/EC of 29 April
1999. - In 1994, the Agency set up shop in Copenhagen
with a skeletal staff of 6 people. - By 2000, the EEA had a staff of 65 and a budget
of 18.5 MEUR. - A core task of the EEA is toestablish and
coordinate the EIONET in order to collect,
process and analyse environmental data.
5EIONET - The Network
EIONET is the main vehicle of the European
Environment Agency to collect data, information
and knowledge for the process of reporting on the
state of environment. The core network connects
more than 500 institutions in the 18 EEA member
countries.
Each member state operates a co-ordinating
institute (National Focal Point - NFP) and nine
expertise centres (National Reference Centres -
NRCs).
6Organisational Network Main EIONET nodes
- EEA the central node of the extended network
EIONET. - ETCs multi-national consortia, contracted by EEA
to execute tasks of EEA's work programme. ETCs
work as an extension of the Agency and are
responsible for data collection in their topic
area. - NFPs are appointed and funded by member
countries and responsible for the coordination of
national activities related to the EEA work
programme. - NRCs are nationally funded institutions with
expertise in environmental areas corresponding to
ETC areas. Collectors and providers of national
environmental data.
Contact Information is a (the) central
requirement/asset

17EIONET Meta Data Standard
- Global Environmental Locator System Element Set
(GELOS) - adopted from G7 working group on environmental
metadata in late 1996 - based on GILS
- DC compliant
- focus on both, discovery and description
- contains qualifiers for contact information
- however, datamodel and applications consider
actors as individual resources - XML as exchange format
18Data model
- distinction between addresses and data sources
- following relations are possible
- one/several persons is/are related to an
organisation - data sources are related to one/several
organisations - and/or persons
- data sources are related to one/several data

General Multilingual Environmental
Thesaurus consists of 5200 terms translated
into 15 european languages polyhierarchical incl
udes synonyms sorted by environmental
themes used for indexing and discovery ISO
639-2 for language coding
25Searching and Indexing with GEMET
26Geographical Information
- NUTS Code V7

30Need for environmental domain?
The environmental community cuts across almost
every domain Administration Legislation Geogra
phical Information Science (Geology, Chemistry,
Physics, Biology .....) Harmonisation efforts
are basically hopeless, unless built on existing
initiatives like DC Construct environmental
schema/application profile that builds on
existing namespaces
