1. SCIELO AS AN OPEN ARCHIVE: the development of SciELO / OpenArchives data provider interface Prof. Carlos H. Marcondes Federal Fluminense University/ Information Science Department, Brazil marcondes@alternex.com.br © Marcondes

2. SUMMARY What is SciELO ISIS database format and Developing Countries Information Systems Technical overview Conclusion © Marcondes

3. What is SciELO - S ci entific E lectronic L ibrary O nline Set of tools for developing a web digital library of scientific electronic journals Several SciELO Web Gateways, holding Brazilian electronic journals and also Latin American and Spain Provides enhanced services to Scientific Journals from developing countries, concerning –electronic publishing –digital preservation through the use of SGML –access through a web search interface –cross search different electronic journals –SciELO/Open Archives interface: increases visibility of journal articles held in SciELO through an interface compliant with Open Archives Protocol for Metadata Harvesting SciELO uses CDS/ISIS software database format © Marcondes

4. CDS/ISIS software and Developing Countries Information Systems Computerized Information Service / Integrated Scientific Information System –Textual database management system, planned for bibliographic and documentation systems –Originated in ILO at early 60’s –Maintained by UNESCO since 70’s –1985: first microcomputer version –1995: first Windows version –Largely used in developing countries information systems © Marcondes

5. Open Archives Protocol for Metadata Harvesting - OAI-PMH - overview An Open Archive is a Web server with facilities for electronic publishing, storage, preservation and access to scientific digital documents. Open Archives Protocol provides interoperability between electronic archives holding digital documents Two roles: –Data Provider: internet servers with electronic archives holding digital documents and metadata about them. Data Providers expose metadata about their documents –Service providers: use metadata automatically collected from Data Providers to develop value-added information services as: unified access, peer-review, qualified databases, etc. © Marcondes SciELO OAI interface

6. Open Archives Protocol for Metadata Harvesting overview How Service Providers and Data Providers interact: –Service Providers: send requests -Verbs - for metadata stored in Data Providers Verbs: Identify List Metadata Formats List Sets List Identifiers Get Record List Records –Data Providers: answer to requests from Service Providers sending metadata about digital documents they hold © Marcondes SciELO and Open Archives

7. Implementation of OAI-PMH in SciELO – an OAI-PMH Data Provider Server Feasibility study: local computer implementation of two verbs: ListIdentifiers and GetRecord Pilot-project: –Implementation of all six Verbs –Implementation of OAI-PMH Set feature as each journal collection –implementation of resumption token –PHP language used URL: http://www.scielo.br/oai/scielo-oai.php © Marcondes

16. Conclusions: 4Generalization of SciELO/OAI solution to metadata databases in ISIS format 4Availability of free STM information: opportunity to developing countries 4Need of technological tools for developing countries publish and access information of their own interest © Marcondes
