We provide a set of ontologies that model the different domains of published data. These ontologies have been modeled using a combination of RDF Schema and OWL and are now self-documenting in Spanish and English using the RDF property rdfs: label and rdfs: comment

The current published ontologies are:

• Norms: model of legislative norms of Chile.

• Biographies: model of natural and juridic persons, that belongs to politic scope, oriented to definition of parliamentary biographies.

• Geographic information: model of geographic and electoral division of the country.

• Congress: operation model of parliament.

For the modeling, the following vocabularies have been used:

• (foaf) Friend of a Friend: FOAF is a project devoted to linking people and information using the Web. Regardless of whether information is in people's heads, in physical or digital documents, or in the form of factual data, it can be linked. FOAF integrates three kinds of network: social networks of human collaboration, friendship and association; representational networks that describe a simplified view of a cartoon universe in factual terms, and information networks that use Web-based linking to share independently published descriptions of this inter-connected world. FOAF does not compete with socially-oriented Web sites; rather it provides an approach in which different sites can tell different parts of the larger story, and by which users can retain some control over their information in a non-proprietary format.

• (skos) Simple Knowledge Organization System:SKOS Core provides a model for expressing the basic structure and content of concept schemes (thesauri, classification schemes, subject heading lists, taxonomies, terminologies, glossaries and other types of controlled vocabulary).

• (dc) Dublin Core:The Dublin Core element set defines a set of metadata elements for cataloging library items and other electronic resources.

• (dbpedia-owl) DBPedia:The DBpedia Ontology is a shallow, cross-domain ontology, which has been manually created based on the most commonly used infoboxes within Wikipedia. The ontology currently covers over 272 classes which form a subsumption hierarchy and are described by 1,300 different properties.

• (gn) Geonames:The GeoNames Ontology makes it possible to add geospatial semantic information to the Word Wide Web. All over 6.2 million geonames toponyms now have a unique URL with a corresponding RDF web service. Other services describe the relation between toponyms.

• (org) Organization:The organization ontology is a core ontology for organizational structures, aimed at supporting linked-data publishing of organizational information across a number of domains. It is designed to allow domain-specific extensions to add classification of organzations and roles, as well as extensions to support neighbouring information such as organizational activities.

The following diagram shows main models developed and their relationships. Aditionally, it shows some of external vocabularies used in our models.
