Resumo
In order to provide greater transparency for scienti c research and the results achieved, a great e ort is
ongoing to make available scienti c data repositories, which allow for di erent researchers to validate,
reproduce and reuse third party scienti c data. With the always increasing use of technology in all
kinds of scienti c facilities, a growing amount of data is collected even from simple experiments. This
scenario presents a new paradigm: the understanding of third party data easily found on data repositories.
Consequently, being able to do useful searches on these data repositories poses a new challenge for
traditional search engines. In this work, the approach taken to help solve these problems was to propose
a semantic layer for scienti c data repository. By using ontologies, with appropriated integration of
traditional search mechanisms, it will be easier for users to nd related data that could be used in their
work, improving the overall scienti c yield. In order to achieve this goal, a ontology was developed,
using the Prot eg e software, for the Neutron Activation Analysis (NAA) data domain. This ontology was
validated by experts from NAA Laboratory of the Reactor Research Center (CERPq) at the Nuclear
and Energy Research Institute (IPEN-CNEN/SP). A prototype of a semantic data repository is, thus,
being developed using the Django web development framework. RDFlib, a software library written in
Python is being used to allow the integration of semantic operations, based on the NAA ontology, with
the relational database layer provided by Django.
