Abstract

As spatial data infrastructures evolves, geospatial data producers became able to provide them to a wide scope of potential users. This user, either human or a search engine, decides to adopt that dataset based on the analysis of the correspondent metadata by comparing data characteristics and their expectations. The Brazilian Geospatial Metadata Profile (in Portuguese, PMGB) offers guidelines to support agents in charge to fill geospatial metadata. However, they often meet the expectations of web search engines. This study aims to propose guidelines to fill the metadata element Abstract to make data more attractive to both human and machine users. This study created alternative versions of Abstracts of geospatial data available at the web based on search engines optimization techniques and the PMGB guidelines. A group of expert users assessed the alternatives by considering their preferences regarding their perception of gain of information between the proposed alternatives. In total, 84.6% of respondents approved the proposed guidelines for filling the Abstract metadata element.
