Abstract

The Tag Ontology defines relationships for semantically annotating taggable things (for example news assets) with domain entities (stuff) and events.

Design Notes

There are two flavours of tag relationships, about and mentions. This allows us a more expressive representation of the entities that appear in a news story and the prominence or importance of that appearance.
It is possible to semi-automatically identify entities mentioned in a news story. Whether that story is about that entity will require editorial oversight. The class of Taggable defines an interface that enables resources to be tagged without constraining and binding what class of resources are taggable. Currently, Assets are taggable, but in the future we may want more flexibility. This approach provides that flexibility. Equally the class Tag provides an interface abstraction for domain entities.
