Making Web Annotations Persistent over Time
TL;DR: This work provides theoretical solutions and proof-of-concept experimental evaluations for two problems: reconstructing an existing annotation so that the correct archived version is displayed for all resources involved in the annotation, and retrieving all annotations that involve a given archived version of a web resource.

Abstract: As Digital Libraries (DL) become more aligned with the web architecture, their functional components need to be fundamentally rethought in terms of URIs and HTTP. Annotation, a core scholarly activity enabled by many DL solutions, exhibits a clearly unacceptable characteristic when existing models are applied to the web: due to the representations of web resources changing over time, an annotation made about a web resource today may no longer be relevant to the representation that is served from that same resource tomorrow. We assume the existence of archived versions of resources, and combine the temporal features of the emerging Open Annotation data model with the capability offered by the Memento framework that allows seamless navigation from the URI of a resource to archived versions of that resource, and arrive at a solution that provides guarantees regarding the persistence of web annotations over time. More specifically, we provide theoretical solutions and proof-of-concept experimental evaluations for two problems: reconstructing an existing annotation so that the correct archived version is displayed for all resources involved in the annotation, and retrieving all annotations that involve a given archived version of a web resource.

Augmenting Europeana content with linked data resources
Bernhard Haslhofer,Elaheh Momeni,Rainer Simon +2 more
- 01 Sep 2010
TL;DR: This work is currently extending Europeana, a platform which links to millions of digital items in European institutions, with an annotation mechanism that exposes annotations as linked data and enriches newly created annotations with links to contextually relevant resources on the Web.
The open annotation collaboration: A data model to support sharing and interoperability of scholarly annotations
Jane Hunter,Timothy W. Cole,Robert Sanderson,Herbert Van de Sompel +3 more
- 01 Jan 2010
TL;DR: The principles and components of the OAC data model are described, together with a number of scholarly use cases that demonstrate and evaluate the capabilities of the model in different scenarios, to provide the optimum approach for the publishing, sharing and interoperability of annotations and annotation applications.

Pundit: augmenting web contents with semantics
TL;DR: Pundit aims at enabling scholars to produce meaningful machine- readable data that captures the semantics of their annotations, by providing a customizable annotation environment, and easy ways of integrating with existing Web archives or libraries.
Annotating the scholarly web
TL;DR: The founder of the non-profit organization Hypothes.is, which has built an open-source software platform for web annotations, has announced partnerships with more than 40 publishers, technology firms and scholarly websites, and hopes that the partnerships will encourage researchers to start annotating the world's online scholarship.

Tom Heath,Michael Hausenblas,Chris Bizer,Richard Cyganiak +3 more
- 01 Jan 2008
TL;DR: This tutorial will provide participants with a solid foundation from which to begin publishing Linked Data on the Web, as well as to implement applications that consume Linked data from the Web.
A formal model of annotations of digital content
Maristella Agosti,Nicola Ferro +1 more
TL;DR: The proposed formal model captures both syntactic and semantic aspects of the annotations and is built on previously existing models and may be seen as an extension of them.

Robust annotation positioning in digital documents
A. J. Bernheim Brush,David M. Bargeron,Anoop Gupta,Jonathan J. Cadiz +3 more
- 01 Mar 2001
TL;DR: How users react to lost annotations, the relationship between types of document modifications and user expectations, and whether users pay attention to text surrounding their annotations are explored, which could contribute substantially to effective digital document annotation systems.
