5. Annotations can be simply seen as “attaching data to
some other piece of data”, e.g. documents, web pages,
parts of text of web pages; the advantage of a semantic
annotation is to have this data formally defined and
machine-understandable. This offers better possibility
for search, reuse and exploitations of the annotations
performed by users.
6. ‣ Simply speaking it consists of a triple with:
‣ A. the information that is annotated (subject);
‣ B. the content of the annotation itself (object);
‣ C. a predicate, that establishes a relationship amongst the two
points above (predicate);
‣ We also have the context in which the annotation has been made
(who made it, when, with which instrument, etc). (metadata)
‣ This holds true for all kinds of annotation, including handwritten
notes beside paper documents.
