Dear all, Apparently I have the bad habit of posting before I have proofread and checked the text. I apologize for that. Hopefully this version is clearer and has fewer errors.
C-E As a part of the homework Patrick and I were asked to have a look into how to adjust FRBRoo to model other mass produced objects than 'publication products'. The issue discussed in this text is related to that homework and may be a part of the answer. The conclusion in the present note is that it may not be correct that E3 Manifestation Product Type should be a subclass of E72 Legal Object. ****************** TYPES and E55 TYPE The current scope note of E55 Type is as follows "This class comprises concepts denoted by terms from thesauri and controlled vocabularies used to characterize and classify instances of CRM classes. Instances of E55 Type represent concepts in contrast to instances of E41 Appellation which are used to name instances of CRM classes. E55 Type is the CRM's interface to domain specific ontologies and thesauri. These can be represented in the CRM as subclasses of E55 Type, forming hierarchies of terms, i.e. instances of E55 Type linked via P127 has broader term (has narrower term). Such hierarchies may be extended with additional properties." A CRM-type (instance of E55 Type) is a concept (a E28 Conceptual object in CRM). A CRM-type represents or denotes a hypothetical set of other instances (members of) of CRM classes. The set is hypothetical in the sense that we don't know all its potential members. Ontologically we assume that there exists a procedure that makes it possible to catalog, characterize or decide whether an instance of a CRM class belongs to (P2 has type) to the set denoted by the concept. For example: In Natural History (systematical biology) every species definition (in CRM a species is an instance of E55 Type), has to prescribe explicitly or implicitly a procedure how to decide that a specimen belongs to a given species. This procedure is an intellectual object and can in CRM be modelled as an instance of E73 Information Object and consequently of E72 Legal Object. The procedure may be controlled by rights and legislation. The type, that is, the concept of the hypothetical set of specimens in the nature is not. *********** MASS PRODUCTION, COINS AND THE CLASS F3 MANIFESTATION PRODUCT TYPE IN FRBRoo Last year Dan Matei raised the issue of how model coins and coin production. He suggested that F3 Manifestation Product Type could be used. F3 is specialized to publication products. Although many non book objects are found in libraries, e.g. CDs, DVDs, stamp and perhaps bank notes, it may be case problems if we extend F3 to cover all sets of items which can be found in a library and documented in a library documentation system? This issue will be discussed in other homework. Here I will examine the model of book production found in FRBRoo as a specialization of the model of mass production found in CIDOC-CRM As a reply to Dan Mateis's question Maria Theodoridou referred to how they had extended CRM with two properties to be able to model coins and coin production: E12 Production. PC1 produced things of type: E55 Type E22 Man-Made Object. PC2 is example of: E55 Type Both PC1 and PC2 are subproperties of P2 has type" ****** In un-extended CIDOC- CRM a (mass) production can be modelled as follows: A) The event for the production: P12 Production. B) Categorization of production: P12 Production P2, has E55 Type C) The outcome of the production: P12 Production, P108 has produced (was produced by), E24 Physical Man-Made Thing D) The categorization of the products: E24 Physical Man-Made Thing, has type E55Type E) Physical source material: E7 Activity, P16 used specific object, E70 Thing F) Immaterial source material, e.g., for books: E7 Activity, P16 used specific object, E70 Thing G) The design or procedure to be followed in the production: E11 Modification P33 used specific technique E29 Design or Procedure In this model instances of E29 Design or Procedure describes how to make things. The produced things are instances of E24 Physical Man-Made Thing. Both classes are subclasses of E72 Legal Object. The type (E55 Type) of the produced things is not. *************** FRBRoo The production of books is not different form the production of anything else. The printing (production) of books (F5 Item) is modelled as follows A) The event for the production: F32 Carrier Production Event B) Categorization of production: F32 Carrier Production Event, R26 produced things of type, F3 Manifestation Product Type C) The outcome of the production: F32 Carrier Production Event, R28 produced, F54 Utilized Information Carrier D) The categorization of the products: F54 Utilized Information Carrier, R7 is example of, F3 Manifestation Product Type E) Physical source material: E7 Activity, P16 used specific object, E70 Thing F) Immaterial source material: F32 Carrier Production Event, R27 used as source, P24 Publication Expression G) E7 Activity P33 used specific technique E29 Design or Procedure ***************** Relation to the general model of un-extended CIDOC-CRM * F32 Carrier Production Event is a subclass of E12 Production * F3 Manifestation Product Type is a subclass of E55 Type * F54 Utilized Information Carrier is a subclass of E71 Man Made Thing * F32 Carrier Production, R27 used as source, P24 Publication Expression is a subproperty of E7 Activity, P16 used specific object, E70 Thing * F32 Carrier Production Event, R26 produced things of type, F3 Manifestation Product Type would be a subproperty of: E12 Production. PC1 produced things of type: E55 Type and finally a subproperty of P2 has type E55. * F54 Utilized Information Carrier, R7 is example of, F3 Manifestation Product Type would be a subproperty of E22 Man-Made Object. PC2 is example of: E55 Type and finally a subpropert of P2 has type E55. ************** CONCLUSION >From the outlines above we see that the model of production of books in FRBRoo >is a specialization of the more general model of production in CRM. There some >minor differences especially in the definition of the R26 being defined as a >shortcut involving a property of a property. This is not important here. The >most important difference is that F3 Manifestation Product Type is a subclass >of E72 Legal Object in addition to being a subclass of E55 Type. Is this a correct ontological analysis? IPR rights are clearly connected to the content modelled as an instance of P24 Publication Expression) the production plan resulting from the design process (layout, form, number of pages, use of material etc.) modelled as an instance E29 Design or Procedure). The concept that there is a certain set of books produced according to a common design and belonging to the same edition is not the subject of IPR. F3 Manifestation Product Type is simply a subtype of E55 Type which can be used to catalog or characterize items. Similar to species not being legal objects (the structure of their DNA may be patentable), instances of F3 Manifestation Product Type should not be instances of E72 Legal Object. If my argument is unsound, then we should introduce a general E?? Product Type which is a subclass of E 55 Type and of E72 Legal Object connected to E12 Production.
