PANDORA: [Presentation (of) ANnotations (in a) Digital Object Repository Architecture] – a video

Christopher Johnson has composed a video about the PANDORA Architecture for the SWIB2016 conference. It is now available at youtube:

Abstract from SWIB program 2016: „The IIIF Presentation API specifies a web service that returns JSON-LD structured documents that together describe the structure and layout of a digitized object or other collection of images and related content.“ IIIF website The dynamic serialization of IIIF JSON-LD structured manifests via SPARQL CONSTRUCT is an interesting possibility that has great potential for cross-domain discovery and rendering of digitized objects with variable criteria. I have explored this possibility by implementing a data model in the Fedora Commons Repository that matches the specifications of the IIIF Presentation API. Fedora has the facility to index objects via Apache Camel directly to a triplestore. With SPARQL CONSTRUCT, the triplestore can serialize normalized JSON-LD as a graph. The use of „ordered lists“ (aka collections) is a fundamental component of JSON-LD and necessary feature of the IIIF manifest sequence which is represented in a canonical RDF graph as a cascade of blank nodes. In order to dynamically create the sequence with SPARQL requires that the data is modelled identically to the IIIF specification. This gist is a representation of a compacted and framed JSON-LD graph that was serialized from a SPARQL query of Fedora metadata. The ability to assemble parts of distinct, disparate and disassociated digital objects on demand in one cohesive presentation becomes a real possibility. For example, the „range“ object is equivalent to a part of a sequence, like a chapter in a book. With SPARQL, it is possible to target ranges from different „editions“ based on a metadata specification (i.e. a person, place, or date) and unify them in a manifest object which is then rendered by a client viewer like OpenSeadragon.

Workshop: Digital Humanities and Social Media. @ „The Maghreb in Transition“, Tunis, 18.-19.11.2016

Digital Humanities have developed over the last 10 years to a major methodological approach in the humanities. Building on humanities computing, DH has built an independent infrastructure within the humanities and now reaches back into several disciplines, including literature, history, history of art and social and political sciences. By stressing the quantitative approach to data and using statistical methods DH has contributed in various ways to bring up new hypothesis for old questions and revived the discussion about the place of humanities in science and
society. This workshop gives and introduction into the aims and methods of
digital humanities and addresses questions of power shifts during the digital
transition of the humanities as well as the role of social media in that
