26. Annotating documents
26.1. What is an annotation?
Annotations are comments, notes, explanations, or other types of external remarks that can be attached to
a Web document or to a selected part of a document. As they are external, it is possible to annotate any
Web document independently, without needing to edit the document itself. From a technical point of
view, annotations are usually seen as metadata, as they give additional information about an existing
piece of data. Amaya uses a special RDF annotation schema for describing annotations.
Annotations can be stored locally or in one or more annotation servers. When a document is browsed,
Amaya queries each of these servers, requesting the annotations related to that document. Amaya
presents an annotation with an icon that is visually embedded in the document. If you single-click
this icon, the text that was annotated is highlighted. If you double-clicks the icon, the annotation text and
other metadata are presented in a separate window.
An annotation has many properties including:
Physical location: is the annotation stored in the local file system or in an annotation server
Scope: is the annotation associated to a whole document or just to a fragment.
Annotation type: 'Annotation', 'Comment', 'Query', ...
26.2. Local and remote annotations
Amaya can store annotation data in a local file system (local annotations) or it can store annotations
remotely, on annotations servers accessed through the Web (remote annotations).
You do not need a server to create local annotations. Local annotations are stored under your
AmayaHome directory, in a special directory called annotations, and they can be seen only by their
owner (according to the system access right setup).
This directory contains three kinds of files:
annot.index: Associates URLs with the files containing the metadata of the annotations.
index + random suffix: Stores the metadata of the annotations related to a given URL. The
metadata is specified in RDF.
annot + random suffix.html: Contains the body of an annotation, stored as XHTML.
At any time, you can convert a local annotation to a shared one by choosing Post to server from the
Tools/Annotations submenu. Once this is completed, the local annotation is deleted because it has been
moved to an annotation server.
26.2.1. Remote annotations
You can store remote annotations in annotation servers so that the annotations can be downloaded by
anyone having the correct access rights, such as is the case of other HTML documents.
Remote annotations are referred to as shared or public annotations, because they can be seen by other
people. If you wish to install your own annotation server, please refer to Annotation-Server-HOWTO.
26.3. Creating an annotation
Before creating an annotation, it is recommended to set some parameters in the Preferences (see section
Configuring annotations).
