We present the first steps toward the Digital Curation of scientometric indexes as Linked Open Data on the Web of Data. As an interdisciplinary research, the methodological approach is based on the lifecycles of Digital Curation proposed by the Digital Curation Centre and Linked Data Lifecycle proposed by the Agile Knowledge Engineering and Semantic Research Group. As a result, the endpoint <http://lod.unicentro.br> is implemented and the historical resource data of three scientometric indexes (Qualis, SJR and SNIP, period 2005-2016) are curated. Therefore, these indexes are available on the Web of Data, promoting the access, reuse, interoperability and processability of digital resources in bibliometric/scientometric researches. We conclude that, by preserving the three datasets as Linked Open Data, the endpoint <http://lod.unicentro.br> allows: i) the availability of resources on the Web of Data; ii) the navigability between the resources distributed on the web; iii) the exploration of the relationship between the available elements; and iv) the replication of results in scientific studies over time.
