This paper focuses on data science in digital cultural heritage in Brazil, where there is a lack of systematized information and curated databases for the integrated organization of documentary knowledge. Thus, the aim was to systematically map the different forms of information organization and representation applied to objects from collections belonging to institutions affiliated with the federal government's Special Department of Culture. This diagnosis is then used to discuss the requirements of devising strategies that favor a better data science information infrastructure to reuse information on Brazil's cultural heritage.Content analysis was used to identify analytical categories and obtain a broader understanding of the documentary sources of these institutions in order to extract, analyze, and interpret the data involved. A total of 215 hyperlinks that can be considered cultural collections of the institutions studied were identified, representing 2,537,921 cultural heritage items. The results show that the online publication of Brazil's digital cultural heritage is limited in terms of technology, copyright licensing, and established information organization practices. This paper provides a conceptual and analytical view to discuss the requirements for formulating strategies aimed at building a data science information infrastructure of Brazilian digital cultural collections that serves as future projects.

This article reflects on barriers to the use of information and communications technology (ICT) by museums. The use of ICT in museums has become increasingly relevant over the last decade, especially in terms of the distribution and availability of museum collections in digital format, contributing to understanding the social role of museums and their relationship with their audience. This investigation aims to reflect on and understand the barriers to the use of technological tools by museums to preserve and socialize digital collections, particularly digital repositories. A qualitative data collection methodology was applied to 26 national museums in Brazil. A diagnostic matrix consisting of seven dimensions was used to analyze the different aspects of museum operations and institutional characteristics. The results obtained indicate the need to devise a specific policy for technological development in museums that goes beyond technical aspects and includes understanding the role of these institutions in society. This investigation is part of a wider study aimed at creating a diagnostic model to assess the technology maturity level of museums.

The use of digital technology and creation of network infrastructures in Brazil’s national museums has emerged as an important research topic in recent years, either from the perspective of finding new ways to socialize collections and to expand their potential or by implementing new practices to manage and organize these institutions. This article aims to debate how museum education sectors can establish new social practices of digital culture based on the perspectives identified by digital technologies. To this end, a reflection was carried out based on the educational potential proposed by the National Policy on Museum Education, and a case study was performed based on the experience of the Tainacan project, implemented by the Brazilian Museum Institute for the socialization of museum collections in the digital universe. The results are still preliminary; however, they can show how the practices of digital culture, considering that the network has its own characteristics and socialization strategies that are inherent to it, which can be used in favour of museum education, constitute operational possibilities, which can be applied in the reality of Brazilian museum institutions.

The demand for integrating and sharing heterogeneous data online has attracted the interest of cultural institutions in making information access and retrieval more effective via Semantic Web technologies. The present study proposes a digital repository for 3D scans of modernist sculptures in public spaces in the city of Rio de Janeiro, Brazil, with a view to ensuring access, use, reuse and preservation of this information. This is a qualitative exploratory experimental study based on the scientific literature and specific empirical material. It presents the analysis results of vocabularies for physical artifact documents and their digital counterparts on the Semantic Web and a discussion on how these align with the nature of the metadata determined here, as well as a metadata modeling prototype implemented on the Tainacan platform and aimed at cataloging digital 3D replicas. We claim that the proposed model for documenting cultural heritage assets on Tainacan is easy to implement, in that it uses accessible technology with a wide internet user base, highly expressive in its descriptions of 3D and multimedia content and based on well-established metadata and ontology standards recommended by regulatory bodies and communities such as the World Wide Web Consortium and International Organization for Standardization.
