Introduction

Our approach to this mapping is to wherever feasible use existing ontologies created by the Semantic Web community. In some cases may result in minor loss of information (for example the translation flag on some text elements).

Ontologies

The following ontologies have been used in this mapping

foaf - Friend of a Friend Vocabulary
bibo - Bibliographic Ontology
dcterms - DCMI Metadata Terms
cerif - CERIF Publication types to bibo mapping.
aktp - AKT Portal Ontology

CERIF Mappings

Core Entities

Person

The Person class has been primarily mapped to the FOAF ontology.

The cfPers_Class table has not been mapped as there is no defined classification ontology. The RDF class foaf:Person should be asserted for each person.

Table	Field	Description	RDF Equivalent	Required processing
cfPers	cfSex	Gender	foaf:gender	Valid values for foaf:gender are 'male' and 'female'.
cfPers	cfURI	URI	foaf:homepage	Validation to ensure all URIs are fully qualified.
cfPersName	cfFirstNames	First Names	foaf:firstName
cfPersName	cfFamilyNames	Family Names	foaf:family_name
cfPersName_Pers	cfPersNameVar	Name variants	foaf:name	Requires some validation to split up multiple entries in a single field.
cfPersName	cfFirstNames, cfFamilyNames	Full name	foaf:name	Strings must be joined together.
cfPersKeyw	cfKeyw	Research Interest Keywords	aktp:has-research-interest	String processing; Split on commas. Create entities for each keyword.

Project

The cfProj_Class table has not been mapped as there is no defined classification ontology. The RDF class foaf:Project should be asserted for each project.

Table	Field	Description	RDF Equivalent	Required processing
cfProjTitle	cfTitle	Project Title	dcterms:title
cfProjTitle	cfAbstr	Project Abstract	dcterms:abstract
cfProj	cfStartDate	Start Date	??	Date format translation.
cfProj	cfEndDate	End Date	??	Date format translation.
cfProj	cfAcro	Acronym	foaf:name
cfProj	cfURI	URI	foaf:homepage	Validation to ensure all URIs are fully qualified.
cfProjKeyw	cfKeyw	Research Interest Keywords	aktp:has-research-interest	String processing; Split on commas. Create entities for each keyword.

Organisational Unit

The cfOrgUnit_Class table has not been mapped as there is no defined classification ontology. The RDF class foaf:Organization should be asserted for each project.

Table	Field	Description	RDF Equivalent	Required processing
cfOrgUnitName	cfName	Organisation Name	foaf:name
cfOrgUnit	cfArco	Acronym	foaf:name
cfOrgUnit	cfURI	URI	foaf:homepage	Validation to ensure all URIs are fully qualified.
cfOrgUnitNameKeyw	cfKeyw	Research Interest Keywords	aktp:has-research-interest	String processing; Split on commas. Create entities for each keyword.

Result Entities

Result Publication

Publication Types

The type of a publication, encoded in the cfResPubl_Class table, is mapped to RDF types below. We have extended the bibo hierarchy of document types where appropriate to include the classes defined in the CERIF 1.0 Semantics document. In some cases these are equivalent classes to bibo classes, and in other they are subclasses.
