Prov and real things

  1. 1. PROV and Real Things LAND AND WATER Simon J D Cox & Nicholas J Car X December 2015
  2. 2. The problem preparation workflow on a specimen’s journey from collection to analysis is complex, and variable its description must be available in order to evaluate or reproduce observations PROV and real things | Cox & Car2 |
  3. 3. Real workflows PROV and real things | Cox & Car3 |
  4. 4. Proposal: 1. Describe specimen preparation using a generic process model (i.e. input-process-output) 2. Use W3C PROV as the generic process model PROV and real things | Cox & Car4 |
  5. 5. ISO 19156 Specimen model Specimen is a kind of Sampling Feature • [0..*] Preparation Steps Issues: • Can’t tie the predecessor/successor to a preparation step • UML/XML only SF_Specimen + currentLocation: Location [0..1] + materialClass: GenericName + samplingLocation: GM_Object [0..1] + samplingMethod: SF_Process [0..1] + samplingTime: TM_Object + size: Measure [0..1] + specimenType: GenericName [0..1] SF_SamplingFeature + lineage: LI_Lineage [0..1] + parameter: NamedValue [0..*] Location + geometryLocation: GM_Object + nameLocation: EX_GeographicDescription GFI_Feature SamplingFeatureComplex + role: GenericName PreparationStep + processOperator: CI_ResponsibleParty [0..1] + time: TM_Object SF_Process +processingDetails 0..* Intention +sampledFeature 1..* 0..* +relatedSamplingFeature 0..* PROV and real things | Cox & Car5 | ISO 19156:2011 Geographic Information – Observations and measurements (S J D Cox, Ed.)
  6. 6. Specimen model in sam-lite PROV and real things | Cox & Car6 | S J D Cox, Ontology for observations and sampling features, with alignments to existing models, Sem. Web (in press)
  7. 7. What is PROV? Core classes: - Entity - thing of interest (‘endurant’) - Activity - transformation event (‘occurrent’) - Agent - responsible party or process PROV and real things | Cox & Car7 | T. Lebo, S. Sahoo, D.L. McGuinness, PROV-O: The PROV Ontology, (2013). http://www.w3.org/TR/prov-o/
  8. 8. PROV applications The entities of interest are usually • Datasets • Publications, papers, reports, products i.e. information objects How about the ‘internet of things’? PROV and real things | Cox & Car8 |
  9. 9. Specimen  PROV mapping Specimen sub-class-of prov:Entity . Process sub-class-of prov:Agent . Preparation-step sub-class-of prov:Activity . Specimen is a real thing! PROV and real things | Cox & Car9 |
  10. 10. Example: carbonate analysis PROV and real things | Cox & Car10 | Entities: specimens, data, reports Agents: people, machines Activities: preparation-steps, observations
  11. 11. Example: insect taxonomy PROV and real things | Cox & Car11 | Entities: specimens, data, reports Agents: people, machines Activities: preparation-steps, observations
  12. 12. URIs for agents  some ‘vocabularies’ required • People, including functional positions (‘the lab technician at the time’) • Machines, other pieces of kit • URIs for specimens – see IGSN PROV and real things | Cox & Car12 |
  13. 13. Elaborations PROV and real things | Cox & Car13 | These examples use only ‘core’ PROV: qualifiedInfluence properties enable recording of more detail
  14. 14. Provenance vs provenance Provenance in GLAM world = chain-of-custody of non-reproducible things To verify identity, but also important for assay data, drug-testing, forensics Provenance in data world = transformations of reproducible things Provenance in the world of specimens = transformations of non-reproducible things ….? PROV and real things | Cox & Car14 |
  15. 15. Summary • Original application of PROV to real things • Core PROV model capable of capturing specimen prep & analysis • Specialization might make it stronger, but little needed • Bringing ‘data’ provenance home to the GLAM application … PROV and real things | Cox & Car15 |
