Problem and Objectives. ANACOM (Portuguese National Authority on Communications) is the regulator, supervisor and representative of the communications sector in Portugal. Through the years, ANACOM has been developing a kind of a flat controlled vocabulary: a list of controlled terms, without any structure and without specific a priori relations to the DC properties in use. One of the requirements of the project now in hands is to organize that list into one or more controlled vocabularies, relate them with other LOD vocabularies, encode them in SKOS and make them open in at least two languages (Portuguese and English).

Methodological Approach. We will adopt a hybrid approach, combining the best features of two methodologies: Ontology Development 101(1) and the “Process and Methodology for Developing Core Vocabularies” used by the European Programme ISA (2). We will use qualitative research techniques, such as interviews and focus groups to analyse and validate the relations between the terms.

Expected Results. This article presents a work in progress comprised of the whole process starting on the organization of the terms and ending in the first version of the controlled vocabularies encoded in SKOS.
