MetaOpenGov: metadata model for the Brazilian Open Data Portal

Objective:  to propose a metadata model for the representation and organization of information on the Brazilian Open Data Portal. Specifically, we sought to (i) identify and analyze the types and formats of open data published, standards and metadata used on the Brazilian Open Data Portal and (ii) propose a descriptive representation structure for the Brazilian federal government's open data on the Brazilian Open Data Portal using metadata.

Method:  this is an applied, exploratory and descriptive study with a qualitative and quantitative approach, divided into two stages according to the specific objectives. Bibliographic and documentary research techniques were used, as well as direct observation on the Brazilian Open Data Portal, between July and November 2024.

Results:  after identifying the Brazilian context of open data, standards and elements for organizing and representing information, the results of the stages were systematized to create the MetaOpenGov metadata model. The model is based on three pillars: legislation and documentation; standards and instruments for organizing and representing information; and the existing structure of the Portal, proposing recommendations for the hierarchical structure, division into categories (organization, datasets, resource and reuse) and 84 metadata corresponding to the Data Catalog Vocabulary 3 standard and its respective validation.

Conclusions:  it was concluded that the recommendations of this research can support significant changes in the Brazilian context, promoting interoperability and accessibility for the effective reuse of data by society, highlighting the essential role of information professionals in the development of open data policies.
