The aim of this paper is to present a model able to serve as a uniform solution for terminological issues in order to build a solid semantic structure as a basis to link the different poetic systems. This structure will be used to publish repertoires on the web in a structured format and using open standards in order to build an open-source and collaborative platform based on a poetic ontology which lets interoperability among the different European metrical repertoires with different applications, such as faceted searches based on SPARQL or different kinds of visualizations, very helpful for comparative analysis.
