PIEDRA, Nelson et al. Framework for the integration of digital resources based-on a Semantic Web approach. RISTI [online]. 2015, n.spe3, pp.55-70. ISSN 1646-9895.  http://dx.doi.org/10.17013/risti.e3.55-70.

From the point of view of access to metadata from distributed repositories, the Open Archives Initiative (OAI) proposed a protocol for the interchange and harvesting of metadata called OAI-PMH. This protocol provide a low degree of interoperability, however, with an approach based on semantic technologies, the interoperability of data can reach a higher level; thus, each digital library can retain their specific local qualities and will not require reassign them in order to standardize the exchange, re-use or harvesting of digital resources. In this paper, the process for the extraction of metadata, generation and publishing linked data in order to improve integration and interoperability between resources stored on Digital Libraries is presented. The proposal facilitates the existence of diversity of methods and standards in the processes of each supplier of digital resources.
