The document discusses an iterative and incremental linked data life cycle for enhancing linguistic resources with geospatial information. It involves designing URIs and vocabularies, modeling data from a relational database as RDF using R2RML, generating and publishing the data using Pubby, and exploiting it through a SPARQL endpoint and a map viewer called map4rdf. The goal is to publish linked data about villages in Africa combined with their names and locations.

7. Reuse as much as possible available vocabularies
• http://linguistics-ontology.org/
• GOLD is an ontology for descriptive linguistics.
• We have resued some elements from this ontology
• Also we have reused the WGS84 Geo Basic
Vocabulary http://www.w3.org/2003/01/geo/
