In Loco Semantics is a digital content production and annotation methodology, designed to be blended with popular content producing tools, as word processors and spreadsheets. It is characterized by four principles:
- In Loco Annotation: the annotation process occurs concomitant to the content production (in loco).
- Metaphor Integration: the metaphors and models adopted in content annotation are aligned with those adopted for content production.
- Interoperability: in loco annotation strategies are designed to enable automatic information extraction and conversion to Semantic Web open standards.
- Semantic Persistence: in loco annotation elements are connected to unification ontologies, which will guarantee their equivalent interpretations in different contexts, subsidizing the semantic persistence among transformations.
