Towards an integrated repository for research and management of archaeological 3D assets
Sorin Hermon
“…Where is the wisdom we have lost in knowledge?
Where is the knowledge we have lost in information…?”
The Rock (1934)
T. S. Eliot
Archaeological assets Archaeology
– Uncover physical remains of past human activities
• Excavations (various methods)
• Surveys (remote, direct)
– Unfold their stories
• Levels of description
• Different “philosophical” approaches
• Variety of analysis methods
• Various interpretations
Archaeological assets – Objects (which ones enter this category?)
• in their (original) context
• In archaeological context
– Context itself as an asset • Granularity of recording
• “Accuracy” of registration
3D assets
3D (digital) representation – Documentation of an archaeological asset
• Documentation method and its influence on result
• Measure of matching with archaeological asset
– Interpretation • Virtual reconstruction of an asset (context, object, both)
• Visualization issues – how to represent uncertainty of reconstruction
How to capture and “embed” information about 3D assets
– Paradata (data about resources inferred through actions) • How (archaeological) data was created (recognize relevant sets)
• How to record paradata
– The London Charter • Principles
• Documentation
Conceptual challenges
Misconceptions about information – Russell Ackoff
Common assumptions Reality
Users need more information Information overflow
Users need the information they look for Users fail to consider, filter, and prioritize information they already have.
If users get the information they want, they will make better decisions.
Users do not know how to comprehend or correctly apply complex information.
More communication will result in improved performance.
More communication can create conflicts, waste time, and displace more important work.
Users do not need to know how an information system works, only how to use it.
Lack of knowledge about an information system limits their use of it, their ability to invent new interaction paths, evaluate provided information and solve problems encountered in its use.
Technological challenges Repositories (of knowledge)
– Relation between data, its presentation and cognitive processes
– Assessment of “data quality”
– Data publication beyond the mere “need” for publication
– Rich Internet Applications
– Systems thinking (understand how things (systems) influence one another within a hole)
– Data navigation models – navigation paths through data properties (associations?)
3D Repository – Repository
• Provenance
• Semantic classification
• Model structure
• Web publication without the need of plug ins (x3dom)
• Interaction tools (more need to be developed)
The Science and Technology in Archaeological Research – the Digital Cultural Heritage group
Main research topics
– (3D) documentation of cultural heritage assets
– (3D) scientific visualization
– Digital libraries
– Europeana (aggregator, mapping)
3D repositories
– Definition of concepts
– Metadata
– Mapping tools
– Tools for interaction with digital content
STARC metadata
