“…While users are browsing and contributing to a shared annotation server, they are unaware of others using the system simultaneously. Through a previous project, we developed Vannotea, 34 an application that allows real-time collaborative indexing, annotation, and discussion of audiovisual content. Figure 10 illustrates how we have extended Vannotea to allow this kind of interaction to take place.…”

This paper describes the AnnoCryst systema tool that was designed to enable authenticated collaborators to share online discussions about 3D crystallographic structures through the asynchronous attachment, storage, and retrieval of annotations. Annotations are personal comments, interpretations, questions, assessments, or references that can be attached to files, data, digital objects, or Web pages. The AnnoCryst system enables annotations to be attached to 3D crystallographic models retrieved from either private local repositories (e.g., Fedora) or public online databases (e.g., Protein Data Bank or Inorganic Crystal Structure Database) via a Web browser. The system uses the Jmol plugin for viewing and manipulating the 3D crystal structures but extends Jmol by providing an additional interface through which annotations can be created, attached, stored, searched, browsed, and retrieved. The annotations are stored on a standardized Web annotation server (Annotea), which has been extended to support 3D macromolecular structures. Finally, the system is embedded within a security framework that is capable of authenticating users and restricting access only to trusted colleagues.

“…Vannotea [14] and COHSE [15] are examples of annotation systems supporting both free-text and semantic annotations. Vannotea extends the Annotea schema to annotate objects of any media type, where annotations can be free-text, files, URLs or terms from a controlled vocabulary (e.g., WordNet) or ontology.…”

Abstract. Digital Libraries (DLs) usually provide facilities for browsing and searching their collections, and can enhance noticeably learning activities. The integration of an annotation tool with a DL can foster knowledge exchange between instructors and learners. It is important that an annotation system for DLs should be easily integrated with existing DLs. This paper presents an annotation system, called DLNotes, which can be easily embedded in DLs in order to enable free-text and ontology-based annotations. DLNotes also supports supervised annotation activities and allows discussion threads to be associated with each annotation, what is particularly important for e-learning.

“…Vannotea [3] is a collaborative tool that enables fine-grained annotation of objects of any media type, where the annotations themselves can be free-text, files or URLs or from a controlled vocabulary (e.g., WordNet) or ontology. As a result of user demand, Vannotea was recently extended to enable the viewing of multiple related objects simultaneously.…”

Abstract. Annotea provides an annotation protocol to support collaborative Semantic Web-based annotation of digital resources accessible through the Web. It provides a model whereby a user may attach supplementary information to a resource or part of a resource in the form of: either a simple textual comment; a hyperlink to another web page; a local file; or a semantic tag extracted from a formal ontology and controlled vocabulary. Hence, annotations can be used to attach subjective notes, comments, rankings, queries or tags to enable semantic reasoning across web resources. More recently, tabbed browsers and specific annotation tools, allow users to view several resources (e.g., images, video, audio, text, HTML, PDF) simultaneously in order to carry out side-by-side comparisons. In such scenarios, users frequently want to be able to create and annotate a link or relationship between two or more objects or between segments within those objects. For example, a user might want to create a link between a scene in an original film and the corresponding scene in a remake and attach an annotation to that link. Based on past experiences gained from implementing Annotea within different communities in order to enable knowledge capture, this paper describes and compares alternative ways in which the Annotea Schema may be extended for the purpose of annotating links between multiple resources (or segments of resources). It concludes by identifying and recommending an optimum approach which will enhance the power, flexibility and applicability of Annotea in many domains.
