 #### Example 4: `annotations` element annotation
 
-Example 4 contains 3 different annotations. For the first annotation, 
-the subject of the semantic triple is the `dataTable` element with the `id` attribute "CDF-biodiv-table". Notice 
-that the annotation has a `references` attribute that points to the subject id. The object property of the triple 
-is "http://purl.obolibrary.org/obo/IAO_0000136". Finally, the value (object) in the semantic triple 
-is "http://purl.obolibrary.org/obo/ENVO_01000177", which resolves to the "grassland biome" term in the 
-EnvO ontology (http://www.obofoundry.org/ontology/envo.html). Taken together, the first semantic statement could be 
-read as "the dataTable with the id 'CDR-biodiv-table' is about grassland biome(s)".
+All the annotations for a resource can be group together under an `annotations` element. If you use this construct, each
+annotation must have its subject specifically identified with a `references` attribute that points to the subject's id. The group
+of annotations must be placed TO DO< WHERE IN DOC?
 
-The second annotation has as its subject the `creator` element that has the id "adam.shepherd", 
-the object property "http://www.w3.org/1999/02/22-rdf-syntax-ns#type" and the value (object) "https://schema.org/Person". 
-This statement can be interpreted as "'adam.shepherd', the creator (of the dataset), is a person".
