CrIAis a not-for-profit, non-governmental organization that aims to contribute towards a more sustainable use of Brazil’s biodiversity through the dissemination of high quality information. CrIAReference Center on Environmental Informationhttp://www.cria.org.br
Overview of the speciesLinkproject • Objective • Type of collections involved • Number of records • Budget • Technical features • Future plans
The main goal ofspeciesLinkwas to build a distributed system integrating several biological collections and making their primary data available on the Internet. speciesLinkDistributed Information System for Biological Collections http://splink.cria.org.br
ThespeciesLinkproject is being funded by Fapesp (São Paulo state agency) since October, 2001.
São Paulo State Collections fish: 3 mites: 2 herbaria: 4 microorganisms: 3 inventories: SinBiota Geographic distribution of the participating collections
Support to collections • Providing basic equipment and network infrastructure • Helping to choose a management system, when needed • Helping to train and to import data, when needed
Project Cost(2 years) ~US$ 600K
Protocol and Content Schema • DiGIR protocol (Distributed Generic Information Retrieval) Potential to be globally accepted • DiGIR software (Java Portal & PHP Provider) Collaborative development • DarwinCore v.2 Covers the basic content elements (taxonomic identification, location and date of collecting event)

Data Migration Client • Platform independent (java) • Connects to any database accessible via JDBC (simple text files are also supported) • Complete control over data • Low traffic • Possibility to filter sensitive data by using regular expressions

Summing up • Achieved proof of concept • Data is already available (human and machine interfaces) • Triggered off a movement within the collections to improve the quality of data and to increase the amount of available information • Most interesting part of the game: interoperability
