1 Godfrey Rust, Ontologyx © Rightscom 2004DOI Interoperability Workshop June 2004 Metadata interoperability workshop using the iDD to define entities (what is being identified) using the IDD to map metadata schemes (using other schemes) using the iDD by RAs: access, content, management

2 Godfrey Rust, Ontologyx © Rightscom 2004DOI Interoperability Workshop June 2004 infant iDD status report What has iDD got today? COA (Contextual Ontologyx Architecture): model and language OntologyX: 150 families, terms and underlying contextual structure. Mapping syntax & methodology for global, contextual and representative semantics. Initial RA schemes (crossref, mEDRA) formally mapped. Provisional or partial mappings of RDD, ONIX, MI3P and others. Some automated XML schema export. OntX in SQL database (RDF database under development as persistent platform). Strategic: OntologyX/iDD repository for iDD, MPEG-RDD, MI3P, [ONIX]. What are we developing? RDF-based persistence platform – version control, contextual management. Complete formal mapping of ONIX. Contextual transformation engine. Full XML schema import/export. Web mapping tool for RAs, including automated update of local schemes. User agreements. etc

3 Godfrey Rust, Ontologyx © Rightscom 2004DOI Interoperability Workshop June 2004 Act Verb Resource Time Context PnPn TnTn RnRn C1C1 1-n Place 1-n 0-n Relator An intersection of time and place. An Entity in a Context playing a role other than that of Time or Place. A point or portion of time which forms a temporal parameter of a Context. A point or portion of three- dimensional or virtual space which forms a spatial parameter of a Context. The Ontologyx Context Model A Term which describes the nature of a relationship between one entity and another. The characteristic activity or state of a Context Ontologyx semantics are based on the principle that meaning is derived from the specific roles which entities play in events.

5 Godfrey Rust, Ontologyx © Rightscom 2004DOI Interoperability Workshop June 2004 COA (Contextual Ontologyx Architecture) – ontology starter pack Context Time Place Resource Agent Representative Descriptor (string) Name Identifier Annotation Category (denotational string, semantic string or controlled value) Type Boolean Characteristic Quality Adjective Property Quantity Composite (element group or bag) Relator IsSubClassOf, IsSubRelatorOf, IsA, IsSameAs, IsPartOf, IsReciprocalOf, HasDataType, HasCardinality etc

6 Godfrey Rust, Ontologyx © Rightscom 2004DOI Interoperability Workshop June 2004 iDD structure Authorities (namespaces) distinct. Terms have global and contextual meaning. In many schemes this is not clear because there is no underlying dictionary, so the distinctions have to be made. eg Medra:ContributorRole Contextually: An ONIX code indicating the role played by a person or corporate body in the creation of the product. Globally: The role played by a person or corporate body in the creation of a product.

8 Godfrey Rust, Ontologyx © Rightscom 2004DOI Interoperability Workshop June 2004 Contextual mapping: JournalTitle example JournalTitle IsSubClassOf Title JournalTitle HasCCS JournalTitle_CCS #1 IsA JournalTitle #1 IsTitleOf #2 #2 IsA Journal so if you come across… x IsJournalTitleOf y you can deduce that… x IsA Title x IsTitleOf y y IsA Journal CCS (Contextual Constraint Set) A set of triples which provide contextual semantic rules for a term

9 Godfrey Rust, Ontologyx © Rightscom 2004DOI Interoperability Workshop June 2004 Contextual mapping: HostJournalTitle example HostJournalTitle IsSubClassOf JournalTitle HostJournalTitle IsSubClassOf HostTitle HostJournalTitle HasCCS HostJournalTitle_CCS #1 IsA HostJournalTitle #1 IsTitleOf #2 #2 IsContentOf #3 #3 IsA Journal CCS (Contextual Constraint Set) A set of triples which provide contextual semantic rules Note the critical importance of Relators in OntologyX/iDD.

10 Godfrey Rust, Ontologyx © Rightscom 2004DOI Interoperability Workshop June 2004 Representational mapping: DOI Kernel example ResourceKernelMetadataDeclaration HasElement #1 #1 IsA DOI #1 HasDataType DOI #1 HasCardinality !1 ResourceKernelMetadataDeclaration HasElement #2.n #2.n IsA ResourceName #2.n HasElement #3 #3 IsA Type #3 IsOneOf KernelResourceNameType_AVS #2.n HasElement #4 #4 IsA PrimaryLanguage #4 IsOneOf IsoLanguage_AVS #4 HasCodeSet Iso639A2LanguageCode_CS #2.n HasMinCardinality !0 #2.n HasMaxCardinality !n ResourceKernelMetadataDeclaration HasElement #5.n #5.n IsA ResourceIdentifier #5.n HasElement #6 #6 IsA Type #6 IsOneOf KernelResourceIdentifierType_AVS #5.n HasMinCardinality !0 #5.n HasMaxCardinality !n etc RCS (Representational Constraint Set) A set of triples which provide representational semantic rules. All schemes are represented first as an RCS. OK – but what is the semantic relationship between these elements? We need a CCS…

11 Godfrey Rust, Ontologyx © Rightscom 2004DOI Interoperability Workshop June 2004 Contextual mapping: DOI Kernel example (ResourceKernalMetadataDeclaration_CCS) #1001 IsA DoiResource #1001 HasDOI #1 #1001 HasResourceName #2.n #2.n HasPrimaryLanguage #3.n #2.n IsA #4 #1001 HasResourceIdentifier #5.n #5.n IsA #6 etc ResourceKernelMetadataDeclaration SharesValuesWith ResourceKernelMetadataDeclaration_CCS CCS (Contextual Constraint Set) The # (variable) values are common to an RCS and its CCS: this is the mapping which allows OntologyX/iDD to interpret any schema in common terms.

12 Godfrey Rust, Ontologyx © Rightscom 2004DOI Interoperability Workshop June 2004 journalRMD (Journal Resource Metadata Declaration) An XML schema for journal metadata supporting Crossref, mEDRA, CAL and other likely requirements. Prototype for RMDs for any other domains (bookRMD, coursepackRMD…) journalRMD is designed for interchange: it is not a replacement for eg Crossref or ONIX messages (though it could be used by anyone). It is similar to Crossref and mEDRA, but richer and less customized. For example… journalRMD allows for registration of DOIs issued against Journals, Volumes, Issues and Articles, and their Fixations (8 different ResourceTypes where mEDRA and Crossref have no more than four). journalRMD allows for the use of DOIs to link all Resources. CAL will base their schema on journalRMD, but will probably customize. Requires XSLT transforms from Crossref, mEDRA and other participants (being done). iDD mappings support automated change management of mappings and allowed values…

14 Godfrey Rust, Ontologyx © Rightscom 2004DOI Interoperability Workshop June 2004 Cross-domain interoperability… For interoperability across domains, there is a highly generic COA schema.

17 Godfrey Rust, Ontologyx © Rightscom 2004DOI Interoperability Workshop June 2004 infant iDD issues Access? Mapping methodology? Agreements? Costs? (all can be prototyped with JournalRMD)

18 Godfrey Rust, Ontologyx © Rightscom 2004DOI Interoperability Workshop June 2004 iDD use for defining APs? We are likely to need a schema for declaring attributes of a DOI-AP to support its discovery and maintenance and operation. An instance of such a schema may contain, eg: ResourceTypeSoundRecordings,SoundCarriers,Compositions ServiceTypeLicenseApplication, LicensingQuery Places[list of TerritoryCodes] AgentTypeNOT Consumer Terms used in such a schema would be registered in the iDD. (nb: Each of these terms will have a DOI, but the iDD names are the people friendly identifiers, unique within iDD).
