3 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Renardus: a case study n Project aims, concepts and rationale n Collaborative systems and tools to support: n Data modelling, cross-mapping, metadata sharing n System architecture and technical infrastructure n Organisation and collaboration: now and in future n Implementation examples

4 www.renardus.org Aims, concepts and rationale

5 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk What is Renardus? n An EU-funded project (1 Jan 2000 - 30 June 2002) under the Information Society Technologies programme (5th framework) n Collaboration between 7 European countries, representatives of 11 existing subject gateways

6 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Principle aim To build the “Renardus Broker Service” to support European academic and research communities … an academic subject gateway in Europe

7 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Principle concepts n Collaboration (not limited to national organisations) n Integrated views of metadata for heterogeneous Internet-accessible resources n Cross-search and cross-browse functionality n A single interface but no central data repository n Interaction with existing distributed subject gateways and other Internet-accessible collections across Europe

8 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Rationale n There are already many useful quality-controlled gateways across Europe BUT … n Sustainability of projects (now services) is an issue No one country or service can identify, describe and organise all available Internet resources to support the academic and research communities of Europe n Collaboration is needed to maintain quality, improve users’ access and develop sustainable services

9 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Benefits for users/intermediaries n One interface to use/learn n Access to broader collections covering more subjects, countries, languages n Discover resources not necessarily available through local services n European perspective on global resources

10 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Benefits for participating gateways n Shared costs of development and best practice could potentially accelerate development of new services and avoids duplication of effort n Easier to achieve ‘critical mass’ in gateways’ size and number / range of users n Collaboration demands consistent application of agreed technical standards, in turn leading to improved interoperability for gateways

11 www.renardus.org Implementation Timescales, participants, coverage

12 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Implementation timescales n January-May 2001: Alpha and beta systems developed n June-November 2001: Pilot service released for evaluation n March 2002: Showcase preview of operational service n June 2002: Move from project status to service

14 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Renardus gateways (pilot) n DutchESS - Dutch Electronic Subject Service (KB-NL) n SSG-FI - Special Subject Guides (Geoguide, Mathguide, History Guide, Anglistik Guide (SUB, Göttingen) n DAInet - Deutsches Agrarinformationsnetz (ZADI) n DEPOSIT.DDB.DE Document server (DDB) n Resource Discovery Network (UKOLN) n Finnish Virtual Library (Jyväskylä University Library, Finland) n EELS - Engineering Electronic Library, Sweden n NOVAgate - Nordic Gateway to information in Forestry, Veterinary and Agricultural Sciences (Viikki Science Library, Finland)

15 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Coverage (pilot) n 11 subject-specific services covering engineering, maths, social sciences, literature, life sciences, agriculture, fisheries, forestry, geography, history n 2 services covering all subjects, 1 electronic theses n All gateways provide English-language metadata n Some gateways focus on native resources but the majority have worldwide coverage

16 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Language coverage n Limited scope in project timescales/resources n Pilot interface and help texts all translated into Dutch, Finnish, French and German n Translation toolkit developed based on ‘tagged’ templates n Each tagged element of English content replaced with translated words and phrases n Easily updated across all languages

17 Renardus pilot service home page

18 www.renardus.org Metadata modelling, mapping and sharing Issues and collaborative systems and tools

19 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk A common metadata model n To support consistent retrieval and presentation of integrated data from heterogeneous services n Eight elements derived from gateways’ existing data models (survey) n All but one are Dublin Core elements n No Renardus-specific refinements

20 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Renardus data model (pilot) n Mandatory elements: n DC.Title n DC.Description n DC.Identifier n DC.Subject n Recommended or optional elements: n DC.Creator n DC.Language n DC.Type n DC.Country Two administrative elements: SBIG ID, Full Record URL

21 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Classification cross-mapping n Cross-browsing: pinpointed as key functionality n Achieved by mapping local classification systems to common universal classification scheme: Dewey Decimal Classification (DDC) n OCLC research license allows mapping of top levels of DDC n License also obtained for other language versions of DDC top levels to support multilinguality

22 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Classification cross-mapping n Five levels of relevance mapped: n fully equivalent n narrower equivalent n broader equivalent n major overlap n minor overlap n Mapping tool (CarmenX) adapted from CARMEN project to assist mapping

23 CarmenX mapping tool

24 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Experiments in metadata sharing n Not intended to support planned functionality for pilot BUT... n Explore potential for future exploitation of collaborative framework n Using geographical subject headings as testbed

25 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Renardus Metadata Sharing Tool n Developed from work in the SSG-FI project n Comprises database, import/export routines, replication module for exchanging data between partners n Still determining type/extent of collaboration n Enriching existing metadata n Developing workflow routines n Implementing tailored search profiles for partners

26 www.renardus.org System architecture and technical infrastructure Issues and collaborative systems and tools

27 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk A distributed broker system n Renardus is based on a distributed, decentralised architectural model n Requires participating gateways to implement a local Renardus server using Z39.50 (server kit available) n Interoperability achieved through normalization to a common metadata model

28 Renardus architectural model

29 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Normalization Toolkit n Imports metadata from originating gateways n including cross-mapping relationships n Adds acronym and logo (and full record URL) n based on administrative data n Exports records in format compliant with Renardus application profile n including DDC subject entries added automatically on basis of CarmenX cross-mapping tables

30 Example of cross-browsing functionality

31 Example of graphical navigation overview

32 Example of integrated browse results

33 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Monitoring and maintenance n Gateways required to monitor quality of records and performance of servers n Z-server status tool forwards standard simple/advanced queries daily to participants’ Z-servers and presents response time and number of records retrieved for each query n Spong tool is a simple systems monitoring package presenting basic server status information

34 www.renardus.org Organisation and sustainability Issues and outcomes

35 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk Organisational infrastructure n Shift of focus from coordinating role of national libraries and other national initiatives towards other forms of collaboration n If the service is to survive post-project, need to identify: n Tasks and costs of service provision if fully-funded n Subset of tasks to enable continued service provision on a “lightweight model”

36 lesly.huxley@bristol.ac.uk, marianne.peereboom@kb.nl, l.carpenter@ukoln.ac.uk (Potential) players n Renardus Consortium (existing partner organisations) n National and international funding bodies, advertisers, sponsors n Intermediaries offering Renardus services to their customers and users
