The results focus on RDF, presented as a data model that allows the construction of the structure required for Web data connection, providing flexibility in the choice of descriptive elements that are used with library resources. Initiatives of linked data use were identified in libraries, acknowledging results in their employment. The text concludes with the identification of gains from the use of linked data in library catalogues and the need for the data publication be open and interoperable among institutions, expanding the possibilities of new data connections.
