2. Current situation • EU infrastructure projects aim to publish linked open data about scientific observations in geology, biology, archaelogical excavations, digital productions and medicine • Existing standards for scientific observation • INSPIRE –earth science oriented promoted by EU • OBOE – life science oriented, support semantic annotation • SEEK – ecology oriented - framework • Darwin Core – a general use metadata scheme for biodiversity Focus on : • semantic annotation process of data sets

3. Epistemological Considerations • Theories are formalized sets of concepts that organize observations and predict and explain phenomena and demand a solid empirical base of evidence • Raw data provided by the data sets per se are of little use • Scientific observation forms the basis for understanding the phenomena being studied and it is a process by which we advance our understanding of the world. • It common to all sciences the workflow of forming of a hypothesis to perform and explain observations that are made, the gathering of data, and the drawing of conclusions that confirm or deny the original hypothesis. • The difference between the types of sciences is in what is considered data, and how data is gathered and processed • The cultural discourse includes information from all sorts of sciences and product of sciences, i.e. digital productions, biological samples, specimen of physical objects (materials, fluids etc.). • Scientific data and metadata can be considered as historical records.

4. Common Workflow • Form of a hypothesis to perform an observation (select parameters, properties, signals and the way of converting these to data) • Perform the observations. (They are only concerned with objects or events that are observable, either directly or indirectly ) • Explain the observations made and the gathering of data • Draw conclusions based upon this data, (make a scientific hypothesis - tentative explanations about the observations made) • Deduce the implications (test them through further observation, compare the results) • Confirm, deny, re-evaluate the original hypothesis • Formulate valid theories (allow others to repeat the observations)

5. Limitations Problems with the existing standards: • They model observation isolated from other actions that are preceding or following an observation event, • They leave out information that would allow for later assessing, the quality and precision of the results or for re-evaluating existing measured data due to new evidence which would not require redoing the measurement itself, if suitable raw data were provided. • Even though they are using the above standards to publish data in repositories, they typically lack the required information to facilitate effective long-term preservation and interpretation of data.

6. The CRMsci – overview(1) • has been developed bottom up from specific metadata examples such as water sampling in aquifer systems, earthquake shock recordings, landslides, excavation processes, species occurrence and detection of new species, tissue sampling in cancer research, 3D digitization, • takes into account relevant standards, such as INSPIRE,OBOE, Darwin Core, national archaeological standards for excavation, Digital Provenance models and others. • describes, together with the CIDOC CRM, a discipline neutral level of genericity, which can be used as a general ontology of human activity, things and events happening in spacetime • uses the same encoding-neutral formalism of knowledge representation as the CIDOC CRM, and can be implemented in RDFS, OWL, on RDBMS and in other forms of encoding • reuses, wherever appropriate, parts of CIDOC CRM, we consider as part of this model all constructs used from ISO21127, together with their definitions following the version 5.1.2 maintained by CIDOC.

7. The CRMsci – overview (2) • Metadata about: • The human observer • The objectof observation (a “thing”, “something”, a process or a state?), • The observation hypothesis(choice of parameters), • The identityof the object, if any, • The environment, time and location • The conditionof the thing, • The instrumentation and methodused • The identity, authenticity and transmission of the produced records • The inference making

13. S5 Inference Making E1 CRM Entity comprises the action of making propositions and statements about particular states of affairs in reality or in possible realities or categorical descriptions of reality by using inferences from other statements based on hypotheses and any form of formal or informal logic.

14. Applications • Informed by the IAM model (argumentation) • EU FP7 - PSPInGeoClouds • European Space Agency: satellite data • EU FP7-INFRASTRUCTURES-2012-1ARIADNE • Supermodel for CRMarchaeo • EU - FP7 - CP & CSA iMarine • Informs and complements MarineTLO • Extended MarineTLO used in LifeWatch Greece, being promoted to LifeWatch

15. Conclusions • Our aim is : • to open the discussions in CIDOC about subjects concerning the conceptual modelling about products of human activities. • to suggest to CIDOC to approve that modelling scientific activities is a valid scope for CIDOC and could be a working item for the CRM-SIG WG • Needed: Still to be done: Specializations into analytical methods and reference data sets • Links: http://www.ics.forth.gr/isl/CRMext/CRMsci.rdfs
