Data management for eScience in Brazil

In the 5th edition, submitted papers were subjected to a peer review process with up to three reviews per submission. The edition was organized into three tracks with research papers presentations; a keynote talk and a poster session. The scientific application track included two papers. The paper by Bustos et al. [1] used time series analysis in the forecast of fluids in oils reservoirs. The paper by Cugler et al. [2] is one whose version has been extended as an invited paper for this special issue and explores a new field of managing animal sound recordings using database technology. The adoption of techniques from high processing computing in eScience is the theme of track 2. The first two papers discussed techniques involved in natural phenomena modeling and simulation. The first paper [3] discusses the adoption of high performance computing (HPC) environment in the modeling of protein sequence. Next, the paper by Sabino et al. [4] presents the challenges of using clusters of graphics processing units to compute 3-D wave propagation simulations, using finite difference methods. Lastly, the paper by Chirigati et al. [5], also selected for submitting an extended version to this special issue, discusses techniques for deploying scientific workflows in HPC. Finally, the track eScience services included paper in roughly two lines. In the first line, Costa and colleagues [7] explore the availability of deploying eScience in the cloud as services. In the second line, the two other works are related to data modeling including metrics of quality in bio ontologies [8] and a database integration strategy for ecological datasources [9]. The 5th BreSCI workshop also received Prof. Luiz Nicolaci da Costa, astronomer of the National Observatory in Brazil. Prof. da Costa is the head of the LIneA laboratory, responsible for the storage, analysis, and publishing of astronomy catalogs, produced by large surveys. In his talk, Prof. Nicolaci presented the Portal, a software infrastructure from which scientists can query and process scientific pipelines over catalogs. The workshop ended with a poster session. After the workshop, the steering committee of the BreSci, indicated the best papers, whose authors were invited to extend their contributions to a submission to this special issue. Four papers were invited and submitted extended versions, of which two were finally accepted for publication and take part of this special issue.
