2 SOURCES Project Vision Summary White paper Action items

3 Some similar questions Are catalogues sufficient for discovery? Standards, etc. When a common data model should be adopted? Are linguistic differences a barrier? Is Europe special GIwise? Is data quality an absolute value? From FP4 to FP6: Research focus? Education focus?

Are linguistic differences a barrier? Is Europe special GIwise?

4 ETeMII Project s goal A right one! repetition of data acquisition not enough success stories available! Project breakdown (WPs): Reference data Metadata Interoperability

5 None of the above is currently sufficient to satisfy complex SDI objectives Education (incl. training) 1 Need to strengthen educational programmes: a. short-term action reference data b. long-term action metadata c. short-term interoperability How this should be specifically accomplished? Currently: Engineering curricula focus on reference data GeoIT principles, software training and relatively simple applications Project/problem-solving oriented education is behind Emphasis on training not bad not enough

short-term interoperability How this should be specifically accomplished?

6 Education (incl. training) 2 technical material (protocols, Java, Corba, XML, etc.) semantic aspects vs. post-graduate specialization level non-technical issues are poorly if not at all covered in existing programmes (Coleman, 1997), " almost all teachers in this field were educated in a traditional disciplinary approach; rethinking their teaching philosophies and materials to reflect a wider systems-based perspective represents an enormous undertaking".

(Coleman, 1997), " almost all teachers in this field were educated in a traditional disciplinary approach;

7 Education (incl. training) 3 What and how do you teach students for year 2010? "to solve problems using as many disciplines as required", "to learn better to plan, organise, staff, direct, and control interdisciplinary application solutions" (McLaughlin, 1997). So far, Geoinformatics seems to be a suitable paradigm for postgraduate specialisation studies. In its current highly technological form, however, it lacks the intellectual core to serve as a model for basic undergraduate studies.

interdisciplinary application solutions" (McLaughlin, 1997).

8 Specific Programmes Specific initiatives are needed for education and training. Probably the establishment of specific programmes, strengthening cooperation between academic institutions and the industry, similar to the Centre for Property Studies in Canada, look promising.

9 Research 1 Where is the Innovation? Is there any at all? it seems that (technical) interoperability is currently considered a training goal rather than a research topic. TRUE INDEED Current conceptions of SDIs are useful but rather limited (short-sighted) Achieving interoperability through imposition of de jure standards is not very promising and scientifically not challenging.

10 Views on interoperability and standardisation the development of new interoperability standards vs. ETeMII does not believe that achieving interoperability should be focused on standard making (following existing standards, perhaps),

ETeMII does not believe that achieving interoperability

11 Other views on Interoperability and Standardisation Legislation or policy recommendations are not suitable for imposing standards. Reasons for embracing a standard: a. It exists and it is complete across the area of interest; b. it is simple to access and use; and c. it does the job As with political leadership, one must keep in mind that status as a true standard can only be conferred by followers (Coleman & McLaughlin, 1992).

13 Research 3 Semantic integration Current primary objective: better access to GI by enforcing GI and metadata standards and low-level access mechanisms BUT NO mechanisms/methods established to achieve true integration / association / fusion / fission A project, which attempts to make different major European dataset classifications interoperable at the semantic level, would be a good and extremely useful exercise.

18 Research 5 Multi-lingual databases as sources of semantics? EuroWordNet can provide a resource for semantics. But, this is not sufficient. Research is necessary on how cognitive, cultural, linguistic factors affect user understanding especially the everyday end-users. Domain and task ontologies are not always cognitively rich but involve experts understanding and usage of the concepts involved which are often cross-cultural.
