This paper presents the framework to support the interoperability among Semantic Resources (SRs) proposed by the FUNSIEC project. FUNSIEC aims at studying the feasibility of building and maintaining an Open Semantic Infrastructure for the European Construction Sector (OSIECS). FUNSIEC adopted a layered approach where the SRs are mapped at the meta-schema and schema levels. This process produces the respective OSIECS meta-schema and schema, which support the design of the OSIECS kernel - the heart of the OSIECS infrastructure. This paper presents and discusses the elements involved in FUNSIEC's work (e.g. framework, architecture, methodology). Some conclusions and future work complete the paper.
