+This directory contains ontology "TBox" files with class and property 
+definitions or annotations that are intended to be editable in the VIVO GUI.
+
+These files are loaded by the VIVO application when it starts for the first time
+and during later restarts if the contents have changed.  A triple is updated
+if there is no conflicting value for the same subject and predicate that was
+added to the triple store via the GUI or data ingest (e.g. SPARQL UPDATE).
+
+The file vitroAnnotations.n3 contains triples with predicates in the vitro
+namespace and objects that are not literals with language tags.
+
+The VIVO-languages project contains additional language-specific 
+vitroAnnotations.n3 files where all of the triples contain language-tagged
+literals.
+
+VIVO-languages also provides additional annotation files 
+(e.g. initialTBoxAnnotations_en_US.n3) containing triples with predicates
+in ontologies/voabularies outside the vitro namespace (e.g. rdfs:label).
 
 See ../filegraph/README.md for more information about "TBox" files.
