In these days much of the information published on the...
One of the main objectives of open knowledge, and specifically of Open Educational Resource movement, is to allow people to access the resources they need for learning. The first step to that a learner starts this process is to find information and resources according to his/her needs. One of the reasons why OERs could stay hidden and therefore to...

In order to perform semantic interoperability to OER Ecosystem, in an organized and efficient way, this work presents a framework, which aims at helping establishing interoperability in OER Information Systems in a step-by-step manner. The proposed framework combines the traditions of knowledge sharing and creation (human power) with emergent Web technology and knowledge base systems, to create a vast ecosystem of openly shared educational resources, while harnessing today’s collaborative spirit to develop educational approaches that are more responsive to learner’s needs. Interoperability is studied from four aspects: Technical, Semantic, Organizational, and Legal. In our proposal, these four aspects are considered as problems (barriers) to be tackled rather than interoperability to be established.
The framework presented in this work consists of four main parts: Strategic vision, general instruments, technological instruments, OER semantic interoperability ecosystem.
The interoperability and openness of OER ecosystem is enhanced through LOD4OER Framework (Linked Open Data for Open Educational Resources). An interoperability framework is elaborated to structure interoperability issues and concerns. An interoperability measurement approach is designed to characterize the degree of interoperability achieved. A structured Linked Data lifecycle approach is defined showing the main phases to follow to use the LOD4OER framework, and openness and interoperability measurement methods.
