Goddag (general ordered-descendant directed acyclic graph) was published in 2000 as a proposal for a data structure for the representation and processing of complex document structures. Since then, Goddags have been discussed in the markup community and used in practical applications for QA-based retrieval methods, linguistic analysis and textual criticism.
The purpose of the workshop was to collect and assess experience from these discussions and applications, to identify strengths and shortcomings of Goddags compared to alternative data structures, and to initiate modifications and further development and application of Goddags within a wider perspective of research on data structures for complex documents.
