The application of this mechanism is the GDOC (acronym for Document Management, in Portuguese) system, which implements an innovative data model for storing documents in a relational database and handles them in an Intranet. The GDOC system supports document evolution, expressed by the version concept, which maintain the document history. The use of versions, associated with composite documents, allows the existence of many possibilities for the description of the same document, as a consequence of different version combination. In order to obtain a single description of a document, called document configuration, it is necessary to select a version of each component document. In this work, the version selection is done using document characteristics, represented by their attributes. The configuration mechanism also includes the verification of compatibility between component versions, performed with the assistance of rules, generating a consistent configuration.

In this context, ontologies are being used in different domains as an alternative of organizing information and systematizing concepts of knowledge. This paper highlights the use of ontologies in the agricultural domain, more specifically, the chemical analysis of soils. It is presented the ONIACHES Ontology, which supports the process of soil analysis and interpretation of chemical aspects. It is also discussed how ontologies can contribute for the involved domain and the methodology used in the development process of ONIACHES.
