Remarks
Phaidra adopts a modified LOM schema (Learning Object Metadata), with the option of using alternative metadata schemas (MODS – Metadata Object Description Schema, ICCD standards for museums…). Dublin Core metadata are generated from LOM or MODS schemas, with the possibility of other mapping systems integration. Moreover, Phaidra adopts various classification systems (Dewey Decimal Classification, PACS, EuroVoc, ACM), offering the option for the adoption of other systems.
