CRM Digital ¡ ¡ ¡ Requirements Competitors CRM and Provenance Data example About Provenance-based reasoning Conclusions ICS-FORTH September 21, 2011 Outline

CRM Digital Provenance Metadata Requirements 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) ICS-FORTH September 21, 2011

CRM Digital Requirements 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 n import identifiers, metadata n identity of location – GPS data import? ICS-FORTH September 21, 2011

CRM Digital Requirements Processing: Reliable registration of parameters ¡ ¡ Workflow logs, reliable identification of outputs with inputs n input files (URIs!) n output files (URIs!), formats, warning and error reports. n S/W identifiers and parameters, manual adjustments! n 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) n 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 ICS-FORTH September 21, 2011

CRM Digital Competitors 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” n no notion of acquisition (measurement, observation), place n Confuse agentive role with substance of actors, machines, S/W, context n No notion of temporal indeterminacy W 3 C Provenance WG n precondition: No use of a larger reference ontology => a dogmatic reinvention of the wheel…. ”antimodularity of ontologies? ” ICS-FORTH September 21, 2011

CRM Digital Competitors “Provenance Vocabulary” ICS-FORTH September 21, 2011

CRM Digital ICS-FORTH September 21, 2011 Competitors: “Provenir”

CRM Digital CRM and Provenance 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 (ISO 21127)! ¡ 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! ICS-FORTH September 21, 2011
