We do this by exposing an UML model that specifies an ontology for the language. The proposed language is based on Event-Condition-Action rules, where dif- ferent languages for events (including languages for composite events), for conditions (queries) and actions (including complex actions) may be composed, this way catering for language heterogeneity (besides hetero- geneity on the data-model) that we think is essential for dealing with evolution and reactivity in the Semantic Web.15240321engHeterogeneitySemantic webOntologyReactivitySemanticsMathematical modelsWorld Wide WebArtificial intelligenceComputer programmingLanguagesData structuresEvolutionary algorithmsInformation retrievalconference object10.1007/11552222_10https://www.scopus.com/pages/publications/33646170009
