CRM Digital
Scientific data are empirical or synthetic.
Scientific data cannot be understood without knowledge about the meaning of the data and the ways and circumstances of their creation
We use Metadata to assess meaning (view, experimental setup, instrument settings), relevance (depicted things, their status, their conditions), quality (calibration, tolerances, errors, “artifacts”), possibilities of Improvement and Reprocessing.
From generation to use, permanent storage, reuse (life-cycle)
Digital Provenance Metadata Requirements
ICS-FORTH September 21, 2010
CRM Digital
Acquisition: Reliable registration of the process and context conditions
The experimental setup and environment (geometry, light sources, tools, obstacles, sources of noise/reflections etc.)
Capture device type, identity (individual behavior!) Hierarchical model: Inherit metadata common to series of “shots” The identity of the measured or depicted object
import identifiers, metadata identity of location – GPS data import?
Requirements
ICS-FORTH September 21, 2010
CRM Digital
Processing: Reliable registration of parameters Workflow logs, reliable identification of outputs with inputs
input files (URIs!) output files (URIs!), formats, warning and error reports. S/W identifiers and parameters, manual adjustments! process types for reasoning
Reliable linking with captured data
Use and Reuse: parts, wholes and annotation: Composition of final products, information packages (SIP, DIP, AIP)
composition of aggregates, selection of versions or parts for permanent storage, reuse or transfer between labs, to and from Digital Libraries.
Migration to other formats (compatibility and obsoletion) Authenticity, rights
Requirements
ICS-FORTH September 21, 2010
CRM Digital
There is no provenance data standard format. Too many application-oriented, partial, overspecialized solutions. Several stand-alone models, overgeneralizations No integrated ontology of activity context
Competitors: “Open Provenance Model”,”Provenance Vocabulary”,”Provenir”,”Premise”
no notion of acquisition (measurement, observation), place
Confuse agentive role with substance of actors, machines, S/W, context
No notion of temporal indeterminacy
W3C Provenance WG
precondition: No use of a larger reference ontology => a dogmatic reinvention of the wheel….”antimodularity of ontologies?”
Competitors
ICS-FORTH September 21, 2010
CRM Digital Competitors “Provenance Vocabulary”
ICS-FORTH September 21, 2010
CRM Digital Competitors: “Provenir”
ICS-FORTH September 21, 2010
CRM Digital
The Idea: First conceived by Stephen Stead for CHI, San Francisco 2007 Scientific data and metadata are historical records! Scientific observation and machine-supported processing is initiated,
on behalf of and controlled by human activity in physical space-time, not in cyber-space!
Things, data, people, times and places are causally related by events. Other relations are either deductions from events or found by observation events.
CRM Digital: Specialize the CIDOC CRM (ISO21127)! Will allow for rich integrated reasoning (Christ – Ascension – Ivory panel)
Innovations: The Digital Measurement Event transfers from physical to digital world.
Machines “act” due to human initiative and responsibility. Humans use machines. No non-human actors!

CRM DigitalModelling the Acquisition Process (AP)
Register: Who, when, where. equipment identifiers, equipment models, firmware Setup geometry and conditions.
Assumptions: worst case, a completely manual process! Set of objects captured under common conditions. Each object captured by a sequence of “shots” Metadata are stored by “historical order” (like workflow logs)
step-by-step as executed, not as planned! concatenated by referring to identifiers of previously existing or created entities
and initialized events. = robust against exceptions in the planned workflow
Avoid redundancy of information Hold common information as high as possible in a hierarchy of nested activities

Perform the 3D reconstruction of an artefact from images retrieved from the RI
For an input sequence of images, ARC 3D produces a calibration matrix and a depth map for each image identified as usable for the reconstruction.
This output data is then ingested into the RI so that it can be retrieved and loaded into MeshLab to perform the final reconstruction step (integration of the depth maps).

CRM DigitalGood Reasons for Reasoning (3D-COFORM)
The integrated semantic network of provenance metadata allows for supporting data consistency, interpretation, reuse, preservation
Management: garbage collection of all reproducible intermediate results (classify software!) export packages: collect all acquisition data and parameters used for one model.
Preservation: monitor obsoletion of all processing tools, format viewers necessary to interprete or
reprocess certain data.
Property propagation to subevents and derivatives (economy & consistency): For instance, “Which object represents my mesh?” result in long query paths:
“Jesus Christ”. forms part of “Ascension” is carried by: “Ivory Panel”. was digitized by: “MiniDomeEvent2011934”.has created: “A.15-1955model v1.zip”.used as derivation source:…….

CRM DigitalConclusions
CRMdig provides a good high-level model for empirical provenance of digital data, open for further specialization, integrated with arbitrary context representations
CRM-CRMDig outperforms competitors in expressive power and integration potential.
Future work: Theory of property propagation to subevents and derivatives
Needed: Theories of feature conservation by kinds of derivation processes.
