EKT aggregates through searchculture.gr the national cultural content and provides it, as a major contributor, to the european digital library Europeana.
EKT enriches the aggregated content with homogenized chronology and with historical periods using a hierarchical bilingual vocabulary of Greek Historical Periods that has created.
Metadata records are enriched with two separated fields, ‘EKT Chronology’ and ‘EKT Historical Period’. The enrichment is based on original values of time fields (‘date’, ‘created date’ or ‘temporal’) and, for special cases, on ‘description’ or ‘title’. Primarily the chronological field values are being homogenized and subsequently enhanced with terms from the historical periods’ thesaurus. Items already described with historical periods are being mapped to EKT vocabulary and enriched with the respective chronological time spans.
EKT enriches and homogenizes the aggregated content against a hierarchical bilingual Vocabulary of Types that has created.
Metadata records are enriched with a separated field ‘EKT Type’ that holds references to terms of the vocabulary. Therefore, the content of searchculture.gr is been classified to a compact and balanced set of types which gives it semantic cohesion and improves its searchability, presentation and multilingualism.
EKT has set specific requirements against which it validates and certifies the aggregated content at daily basis.
The requirements regard a variety of standards on metadata, digital files and interoperability services of content management systems.
