Needs and Benefits
The innovation potential of this project can be described best by stating
major findings of the Commission experts, made during the intermediate
and final Project Reviews of the successfully completed EULER project:
"The project has undertaken very significant research into
aspects of information management and retrieval within the Dublin Core
and Z39.50 environments. The project has revealed important findings in
relation to the applicability of these standards. The project has also
made valuable explorations into the O(pen) A(rchive) initiative and other
relevant and topical areas.
The project appears to make a significant contribution to the area,
with potential for portability to other disciplines, as well as further
potential for development of the existing service model.
The overall approach is professional and takes into account all relevant
issues, including ongoing discussions on metadata, profiling etc. Partners
contribute constructively to the metadata standardisation process. Library
and end-user needs are reflected to a very high degree. The exploitation
potential is great, also with a view to extending the approach to other
domains. The project and its approach have the potential of becoming a
model for other fields. A richer user interface could make this model even
1.) It is imperative that a solution be found to the technical difficulties
encountered with response times.
2.) Future income generation should be based on securing the participation
of commercial content providers. The service should remain free at the
point of use."
These remarks clearly describe the state-of-the-art position of
EULER services, which are unique in the field, and also give a clear picture
of innovative aspects that will require further work:
A funding scheme (concerned also with commercial considerations) will be
found, to enable a sustainable future EULER service.
The economic viability will be shown in this follow-up project to EULER.
It will help that for this purpose important publishers in the field of
mathematics and other commercial partners such as software producers are
now interested in supporting or associating with a consortium of such a
project. Various new partners have already expressed their interest in
becoming associate partners of the EULER services. Exploitation might furthermore
aim at adopting typical commercial strategies based on Web economy.
Direct "linking" of the EULER gateway to other Z39.50 servers (non-EULER-specific)
without the need of conversion of data will be considered.
Scalability and performance issues will be resolved against the trade-off
between decentralized and centralized architectures. Organizational aspects
in this context will also be taken into consideration.
Issues of access control versus free access will be dealt with in future
The Human-Computer Interface design (search functionality) will benefit
from innovative approaches.
A sustainable service needs to co-exist with all kinds of other initiatives
in the information landscape. Therefore, interfacing with these other services
seems important. Application to other sciences (also cross searches), e.g.
mathematics - physics - computer science opens up additional exploitation
potential. Ways will be found to interact with these other services (also
outside the EU) in a beneficial way for the end-user.
EULER-TAKEUP is based upon the main, state-of-the-art achievements of the
Open, high quality portal
This was the main objective of the EULER project. The concept of a one-stop-shop
site (portal to heterogeneous resources) has been proven technically feasible,
with enabling key features such as cross collection browsing and searching,
consolidated hitlist through de-duplication, etc.
The combination of mathematical bibliographic resources offered is unique.
All types of resources have been integrated with a reasonable amount of
data from important providers.
For the first time a homogeneous access to heterogeneous resources was
implemented (e.g. access to the preprint, the published article, and the
review of the article being available through one single access point).
Record extraction strategies have been implemented by data providers, leading
to a high precision of results.
Incorporation of "alien" data from non consortium partners is possible
(tested with MPRESS, arXiv.org e-Print archive [LANL]).
European dimension, exploitation and impact of results
The project was one of the earliest actions in this area. No comparable
services/systems are available.
A cooperation basis among important content suppliers across Europe has
been established. New workflow models between partners were explored and
implemented. This will lead to a fruitful cooperation in extending the
EULER service to a (commercially) exploitable sustainable service.
Comparisons with and evaluations of related projects/other activities and
their results have been done.
Related projects and other ongoing developments (e.g. DESIRE, DECOMATE,
RENARDUS) might benefit from the solutions developed in EULER.
An exploitation plan has already been developed, taking into account also
commercial considerations, aiming at establishing a sustainable and extended
There's a high recognition of the brand name "EULER" in the mathematical
community, also outside of Europe.
User needs and satisfaction:
Extensive user needs evaluations and result validation activities have
Standardization and technological achievements
Interoperability (e.g. cross searching) and standardization issues have
been solved: The common EULER metadata profile is an optimal solution,
requiring minimal efforts. It is compatible with international standards.
Other standards (Z39.50, Dublin Core, http) have been proved valuable.
Difficult technical problems such as sorting and de-duplication of distributed
result sets have been solved.
Several tools - available for use - were implemented, which enable new
data providers to join EULER with low technical efforts.
The EULER de-duplication identifier (as a byproduct) enables new exploitable
technologies for filling gaps in data providers information resources.
