When we index a ResourceSilo, we can customize how its Resources entitize its content.
For example, when indexing a SemanticMediaWiki, we can redefine its SemanticMediaWikiPage's aEntities() method.
If the SemanticMediaWikiPage itself represents a single entity, we can write:
# Dataspects::DataspectsStandardSystemWikiIndexer.rb
module Dataspects
class SemanticMediaWikiPage
def aEntities
oEntity = Subject.new(self)
Now, if you add nothing more to this class, then your entity would set its direct annotations like this:
- its entity level direct annotations in accordance with http://rails.dataspects.com/explain/indexing#Dataspects::Subject
- its resource level direct annotations in accordance with http://192.168.43.91:3000/explain/indexing#Dataspects::SemanticMediaWikiPage
- its resource silo level direct annotations in accordance with http://192.168.43.91:3000/explain/indexing#Dataspects::SemanticMediaWiki
As you can see in the lists, these 3 classes inherit their corresponding default direct annotations from their respective abstract super classes.
