Abstract : The revival of studies on the Atonist temples of Karnak (program of the French National Research Agency ATON-3D – ANR-08-BLAN-0202-01) required the implementation of an Information Sys- tem dedicated to the Theban talatat that would also be accessible to the scientific community. This IS is associated with software which helps to reassemble the fragmented reliefs (a digital interactive puzzle), constituting a real tool for researchers and providing the knowledge needed to produce and validate hypotheses about the structures and dimensions of the buildings. The database is then enriched with images of the temple’s extrapolated decoration, which involves 3D modelling of these extrapolations. Talatat indexing was based on the Multilingual Egyptian Thesaurus conventions regarding “passport” data, including iconographic description using descriptive operators called unicos. In the spirit of the international movement in favour of open access to scientific data, the talatat metadata and images are accessible online to researchers working on the proto-Amarna or Amarna periods. The talatat metadata is published using RDFa data model mapping for embedding RDF triples within the XHTML of our web pages, which can be extracted by compliant user agents. This corpus is stored in a secured warehouse with strong human and digital infrastructure for preservation of the images and of their metadata.
