Annotatio is an implementation of a client and a server based on the W3C Annotea protocol. It allows you to create and share annotations to various types of documents. Most people can use this program to save comments to HTML documents, but it also supports other types of annotations and XML-like documents. In opposition to the current implementation of the W3C, Annotatio will save enhanced information of the annotation's positioning within the document, which will allow positing the annotation even if the location or structure of the original document has changed. In local mode, it will save all annotations locally, and in remote mode, it will save the annotations on a central Annotea-compatible server, such as Annotatio Server.
