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

2. 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

3. 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

4. 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.

5. 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)

6. 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
