2016 News
December of 2016. EuropeanaEDMtoCTConversion is developed from September, 2016 to convert Europeana Data Model (EDM) records of Europeana into the developed Common Terminology (CT). Europeana offered ways to access their data at http://labs.europeana.eu/api. Thanks to their kind offer, the HarvestEDM program was developed, which harvests their metadata records via their OAI-PMH Service by sets. Thanks to GOD, in the beginning of December 2016, all sets of Europeana EDM records were harvested in rdf/xml form. The harvested EDM records were converted into the developed Common Terminology (CT) in rdf/xml form in the beginning of December 2016. The statistics of the conversion shows high performance of CT, although values and used terms of EDM are very diverse: converted rate as 99.99%; SKOS semantic exact match rate as 67.16%; narrow match rate as 22.98%; broad match rate as 9.8%; and non converted rate 0.00980%.
September 1, 2016. NLKMODStoCT Conversion is developed to convert the provided MODS records for the ancient rare resources of National Library of Korea on August of 2015 into the developed Common Terminology (CT). The statistics of the conversion shows excellent performance of CT: converted rate as 100%; SKOS semantic exact match rate as 85.7%; narrow match rate as 14.3%; broad match rate as 0%; and non converted rate 0%.
August of 2016. MITQDCtoCT Conversion is developed to convert the harvested MIT DSpace records on September of 2015 into the developed Common Terminology (CT). The statistics of the conversion shows excellent performance of CT: converted rate as 100%; SKOS semantic exact match rate as 89.5%; narrow match rate as 10.5%; broad match rate as 0%; and non converted rate 0%.
August of 2016. HarvardtoCT Conversion is developed to convert the provided library of cloud dataset of Harvard library into the developed Common Terminology (CT). The statistics of the conversion shows excellent performance of CT: converted rate as 100%; SKOS semantic exact match rate as 83.7%; narrow match rate as 16.3%; broad match rate as 0%; and non converted rate 0%.
July of 2016. DPLAMAPtoCT Conversion is developed that converts Metadata Application Profile(MAP) of DPLA into the developed Common Terminology (CT). The statistics of the conversion shows very high performance of CT: converted rate as 96.5%; SKOS semantic exact match rate as 62.7%; narrow match rate as 35%; broad match rate as 2%; and non converted rate as low as 3.5%.
March of 2016. CT SKOS crosswalks are developed to enhance understanding and usage of Common Terminology using the found usages of element names/terms of the provided metadata records.
January of 2016. The planned activities are started. Simple Knowledge Organization System (SKOS) crosswalk is being developed for MARC, MODS, QDC, and DC. Europeana 18 million Europeana Data Model records are harvested and the usage of their element names in 31 sets of 1827 OAI list sets are analyzed with a new device, which is cheap but has enough storage. A limitation of the device, unstable connection with the Internet, is found, thus, the harvested 18 million records will be used instead of harvesting Europeana full sets.
January 11, 2016. IOPDL is proved as a not for profit and tax-exempt organization by Internal Revenue Service.
