RELISH and ISOcat10/10/2011RELISH meets LOEWE10
Harmonization of Terminology between GOLD and the ISO Data Category Registry in the RELISH projectThe ILIT team created a suitable transformation of the concepts of the GOLD ontology into data categories. The team in Frankfurt (FRA) has created an MDF data category selection.These data category selections (GOLD and MDF) have been made public.By mapping on the ISOcat data categories, a harmonization of the used semantic categories should be achieved.A chart with interrelations between the MDF, GOLD and standard ISOcat data categories was created; types of relations between the categories were established to be implemented in the Relation Registry and in mapping the categories in the process of lexicon import into LEXUS as well as into RELISH-LIFT interchange formats.10/10/2011RELISH meets LOEWE11
Problems encountered by an attempt of mappingMDF categories are mostly complex ones. They contain a language property (value):- v - vernacular- e – English- n – national- r – regionalGOLD and „standard“ ISOcats do not contain a language propertyGOLD and „standard“ ISOcats are thought of more as concepts, not as their concrete realizations10/10/2011RELISH meets LOEWE12

Does the name of the category help to find a match?The names can coincide, but different phenomena are meant:- The MDF ISO category “citation form (vernacular)”, defined as “a form for representing a lexeme” (DC-3716) should not be confused with the GOLD category “citation”.The GOLD category is defined as “The action of citing or quoting any words or written passage from a publication that allows others to locate and identify the original source. Typical details include the title, author's name, the journal title (for articles), publication date and page numbers used in research.”The MDF ISO category is almostSameAs the ISOcat "sort key" (DC-469), defined as “a form for sorting a printed dictionary”.10/10/2011RELISH meets LOEWE15
