[Open-education] question about vocabulary on research topics

[Elena González-Blanco]

Dear colleagues,

We are working on a project on linked data for our university. We are having some discussions to organize the topics or research and I would like to ask if there is a controlled vocabulary to organize "research topics" or which patterns are usually followed in the projects you know (apart from letting users introduce free keywords...).
best regards

Elena González-Blanco
