Abstract
In LOD, authentication is a key factor in the security dimension of linked data quality models. This is the case of (a) LMS that manages open educational resources (OERs), in training process, and (b) LMS integrated platforms, which also require authenticating users. Authentication tackles a range of problems such as users forgetting passwords and time consumption in repetitive logins in different applications. In the context of linked OERs that are developed in LMS, it is necessary to design guidelines in order to carry out the authentication process. This process authorizes access to different linked resources platforms. Therefore, to provide abstraction methods for this authentication process, it is proposed to work with model-driven architecture (MDA) approach. This paper proposes a security abstraction model on LMS, based on MDA. The proposed metamodel seeks to provide a set of guidelines on how to carry out unified authentication, establishing a common dialogue among stakeholders. Conclusion and future work are proposed in order to generate authentication instances that allow access to resources managed in different platforms.
Highlights
Model-driven engineering (MDE) [1,2,3,4,5] has as one of its first phases the search for the understanding of the problem to be addressed, that is, the knowledge of the problem domain
Taking into account the above, the modeldriven architecture (MDA), a concept promoted by object management group (OMG), is configured as an architecture that provides a set of guidelines to structure specifications expressed as models, following the model-driven software development (MDD) process [6]
MDA makes use of metamodels, which correspond to a set of domain concepts to be modeled and the existing relationships between them, defined in an abstract way. e metamodels allow carrying out a better abstraction of the knowledge domain, through the identification of concepts, rules, restrictions, etc., which operate in the domain, facilitating their understanding
Summary
Model-driven engineering (MDE) [1,2,3,4,5] has as one of its first phases the search for the understanding of the problem to be addressed, that is, the knowledge of the problem domain. Considering that metamodels in the context of MDA are expressed in a 4-layer scheme, for this research process, M0: the instances; M1: the model; and M2: the metamodel layers are considered From this perspective, the need to carry out a quasiexperimental design was proposed, in order to conceptually consider the abstraction process of the security dimension in the context of linked open educational resources, based on metamodels. (a) Context approach: in this phase, in order to identify the theoretical elements of the research, the following question was designed to guide the research process: How to structure a metamodel that provides an authentication abstraction process for the linked open educational resources, supported on linked data quality dimensions?. (e) Results analysis: with the abstraction of the protocol to be followed and the corresponding application in the case of study, the proposed design is evaluated
