PRESSoo: A formal ontology for continuing resources

PRESSoo is an extension of the FRBRoo model (Functional Requirements for Bibliographic Records – Object Oriented). It is a formal ontology designed to represent the bibliographic information relating to serials and continuing resources.

  • 4. 4 The origins: FRBROO - FRBR: a model for libraries (1998) • Identify minimum functional requirements of bibliographic data • Ensure that they meet user requirements • Outcome: a model for bibliographic information: Work, Expression, Manifestation, Item - CIDOC-CRM: Conceptual Reference Model for museums (1998, now ISO 21127:2006) • An ontology for very diverse objects of cultural heritage • Object-oriented • Objective: facilitate exchange of information from heterogeneous sources and improve resources discoverability PRESSoo – Clément Oury – Meeting at Deutsche Nationalbibliothek, Frankfurt, 8th December 2015
  • 5. 5 FRBROO: an extension of CIDOC-CRM - 2000: first discussions on harmonisation of both models (European Library Automation Group, Paris) - 2003: International WG on FRBR-CIDOC harmonisation • Expressing FRBR with concepts, tools, mechanisms and notation conventions from CIDOC CRM • Aligning (or even merging) the two object-oriented models - Successive versions of FRBROO • Version 1.0: 2010 • Currently 2.2 (to encompass FRAD and FRSAD models) - Original FRBR is now FRBRER (to be replaced by FRBR-LRM) PRESSoo – Clément Oury – Meeting at Deutsche Nationalbibliothek, Frankfurt, 8th December 2015
  • 6. 6 Basic structure of CIDOC CRM PRESSoo – Clément Oury – Meeting at Deutsche Nationalbibliothek, Frankfurt, 8th December 2015
  • 7. 7 Why PRESSOO? - A specialized and detailed model was needed to represent serials and ongoing resources • “features” (frequency, medium...) • changes that affect them over the time (continuations, absorptions, splits...) • relationships they can have with other serials (linguistic editions...) - Provide a linked-data friendly data model • To improve interoperability with other datasets - PRESSOO for the ISSN registry • Prepare the publication of (a subpart of) the registry in the LOD • Deal with the differences of description from various national centres (e.g. “date of publication”) • Mapping of NCs’ MARC records to PRESSOO may be customized according to national practices PRESSoo – Clément Oury – Meeting at Deutsche Nationalbibliothek, Frankfurt, 8th December 2015
  • 8. 8 PRESSOO: an extension of FRBROO - PRESSOO: “FRBROO for serials and other continuing resources” • “An ontology which aims to represent the underlying semantics of bibliographic information about continuing resources, and more specifically about periodicals” - FRBROO chosen as reference standard • For its object-oriented approach: convenient for linked data • As it allow interoperability with other cultural fields (as a CIDOC-CRM extension) • Because FRBRER was not perfectly adapted for serials PRESSoo – Clément Oury – Meeting at Deutsche Nationalbibliothek, Frankfurt, 8th December 2015
  • 9. 9 Shortcomings of FRBRER - FRBR Final Report, 1998: • “Certain aspects of the model merit more detailed examination. (…) In particular, the notion of “seriality” and the dynamic nature of entities recorded in digital formats merit further analysis”. - FRBRER: rigidly hierarchical (WEMI structure): lack of flexibility • In FRBRER, the WORK entity is defined as a “distinct intellectual or artistic creation” • Various editions of a serial are seen as so many EXPRESSIONS (e.g. Western and eastern editions of The Wall Street Journal) • Some situations create severe inconsistencies • N.B.: this approach is now disregarded in FRBR-LRM PRESSoo – Clément Oury – Meeting at Deutsche Nationalbibliothek, Frankfurt, 8th December 2015
  • 10. 10 Example of a complex but frequent enough case PRESSoo – Clément Oury – Meeting at Deutsche Nationalbibliothek, Frankfurt, 8th December 2015
  • 11. 11 PRESSOO as FRBROO-based model - FRBROO model defines a “serial work” class (F 18) • Each serial is regarded as a WORK, including all local, linguistic, etc. editions • By ignoring the Expression and Manifestation entities, FRBROO definitively circumvents the logical inconsistencies mentioned earlier - FRBROO and of CIDOC-CRM models are able to express the dynamic nature of serials • or at least, to provide a framework for creating additional classes and properties which express this “dynamic nature” • E.g,: the CIDOC-CRM classes “E 29 Design or Procedure” that accounts for planned behaviours PRESSoo – Clément Oury – Meeting at Deutsche Nationalbibliothek, Frankfurt, 8th December 2015
  • 12. 12 Some aspects of FRBROO - F1 Work: a sum of concepts - F2 Expression: a sum of signs - 3 meanings for "Work": • all concepts conveyed by each individual Expression: F14 Individual Work • all concepts common to various Expressions and serving to identify “bibliographic families”: F15 Complex Work • the concept of adding something to Expressions (e.g. by aggregating them): F16 Container Work
  • 13. 13 Serial works in FRBROO F1 Work F15 Complex Work F16 Container Work F19 Publication Work F18 Serial Work "There is no single expression or manifestation representing a complete serial work, unless the serial work has ended." is a is a is a is a is a

  • 15. 15 PRESSOO: the making of - April 2012: issues of FRBR serial description discussed «in an ISSN perspective» during a technical meeting in Paris - January-March 2013: 7 meetings • Examination of the semantics of each single data element in the ISSN Manual • Can this semantics be expressed using existing FRBROO and CIDOC CRM classes and properties? • If not, then declare specific classes and properties - PRESSOO = sum of specific classes and properties declared through that process • A mapping from the ISSN data elements to PRESSOO is provided in the model - April 2014: 0.5 version submitted to IFLA FRBR review group - June 2014: amended version (endorsed by the FRBR RG) published as 1.0 version

  • 17. 17 PRESSOO: key principles - Descriptive information of a serial makes statements about the past and assumptions about the future • “There is in general no single expression or manifestation representing a complete serial work, unless the serial work is ended” (FRBROO) • “The sum (at a given point of time) of all the expressions of all past issues published so far does not represent the serial work, but can be thought as a “component” of a virtual complete expression that does not exist yet” (PRESSOO) - PRESSOO models the many changes that are likely to occur over time in the life of a serial • What is actually described is a set of issuing rules (publication plan) PRESSoo – Clément Oury – Meeting at Deutsche Nationalbibliothek, Frankfurt, 8th December 2015
