Paulo Freire is the patron of education in Brazil. His main work - the Popular Education pedagogy - influences many educators all over the world who believe in education as a way of liberating poor oppressed people. One of the outcomes of Freire's work is a literacy method, developed in the 1960's. In this paper, we propose the adoption of elements of Freire's Literacy Method for use in a pedagogical pathway towards data literacy. After tracing some parallels between literacy education and data literacy, we suggest some data literacy strategies inspired on Freire's method. We also derive from it a definition for critical data literacy.

With the advent of the Internet and particularly Open Data, data literacy (the ability of non-specialists to make use of data) is rapidly becoming an essential life skill comparable to other types of literacy. However, it is still poorly defined and there is much to learn about how best to increase data literacy both amongst children and adults. This issue addresses both the definition of data literacy and current efforts on increasing and sustaining it. A feature of the issue is the range of contributors. While there are important contributions from the UK, Canada and other Western countries, these are complemented by several papers from the Global South where there is an emphasis on grounding data literacy in context and relating it the issues and concerns of communities.

RESUMOA Política Nacional de Saúde Integral das Populações do Campo, da Floresta e das Águas reconhece a dívida histórica do Estado brasileiro com a saúde dessas populações, apresenta a necessidade de superação do modelo de desenvolvimento econômico e social na busca de relações homemnatureza responsáveis e promotoras da saúde. Como fruto da implantação dessa política, pensando no seu monitoramento e avaliação, estruturou-se em 2012 um Observatório denominado OBTEIA.Objetiva-se apresentar a experiência desse Observatório, focando o seu processo metodológico e nos principais resultados. Este Observatório vem sendo estruturado a partir da criação de uma Teia de Saberes e Práticas, que envolve movimentos sociais, academia e gestoras(es)/trabalhadoras(es) do Sistema Único de Saúde. O foco das ações tem sido o de visibilizar essa população por meio

This paper presents an approach for metadata reconciliation, curation and linking for Open Governamental Data Portals (ODPs). ODPs have been lately the standard solution for governments willing to put their public data available for the society. Portal managers use several types of metadata to organize the datasets, one of the most important ones being the tags. However, the tagging process is subject to many problems, such as synonyms, ambiguity or incoherence, among others. As our empiric analysis of ODPs shows, these issues are currently prevalent in most ODPs and effectively hinders the reuse of Open Data. In order to address these problems, we develop and implement an approach for tag reconciliation in Open Data Portals, encompassing local actions related to individual portals, and global actions for adding a semantic metadata layer above individual portals
