Resumo
Information about a particular subject can be stored in different repositories such as databases,
digital libraries, spreadsheets, text files, web pages etc. In this context of heterogeneous
data sources, to query, possibly in natural language, to integrate information and
to promote interoperability are tasks that depend, among other factors, on the prior knowledge
that an user has regarding location, owner, content description of each information
source etc. More specifically, in the case of database, this information are not usually stored
in a catalogue of the database management system and to obtain is necessary to resort
to the administrator s knowledge database. Another factor is the absence of search engines
to databases in the web that access and make available the information in those
repositories, data are limited due to the organizations themselves. In a shared information
environment, it is highly relevant to make possible access to metadata that describe a data
source, regardlessly of the device and format in which is stored. This study aims to describe
a mechanism to promote interoperability of relational databases with other sources
of information through the extraction and exposing of metadata using OAI-PMH
