What is SciELO - Scientific Electronic Library Online
• 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
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

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.

SciELO OAI interface
Open Archives Protocol for Metadata Harvesting overview
• How Service Providers and Data Providers interact:– Service Providers: send requests -Verbs - for metadata stored
in Data ProvidersVerbs:
IdentifyList Metadata FormatsList SetsList IdentifiersGet RecordList Records
– Data Providers: answer to requests from Service Providers sending metadata about digital documents they hold

SciELO and Open Archives
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

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