Abstract:

The objective of this article is to perform an analysis of some existing technological tools for interoperability between digital repositories. A digital repository is a platform that is responsible for storing, preserving and being a content dissemination tool where each resource is described using metadata, and can exchange information with other digital repositories through interoperability. The utility of working with digital repositories is based on the use of standards for both metadata (for example, Dublin Core) and interoperability (for example, OAI-PMH), facilitating the use, management and understanding of information. Two methodologies were used, one for each of the phases of the work. For the research, the qualitative methodology was used, obtaining information through the queries of the topics involved in scientific literary resources, as well as official web sites of the standards for the interoperability between digital repositories and the tools that are presented. For the case study, Rapid Application Development methodology (RAD) was used because the tool selected for the case study allows to write code in an agile way once the verbs and parameters of the OAI- PMH standard are known and understood, as well as their functions. As a result, we obtain a comparison of the Python-based technological tools for interoperability and a case study that shows how to use the tool that, according to the analysis performed, is the most optimal. As a limitation, some tools do not have enough documentation, which means that trying to use them is complicated. The value of the article is the case study presented, which works as a guide for the use of the Sickle tool, using the six verbs of the OAI-PMH standard and all their possible uses. It is concluded that interoperability by itself has a certain level of complexity, but by using a well-structured technological tool, it is possible to use it for study or implementation in technological solutions that require it.
