Magyar Egyházi Levéltárosok Egyesülete (MELTE), Arca
The Magyar Egyházi Levéltárosok Egyesülete (MELTE) operates Arca, a shared online finding-aid service for Hungarian church archives. Its official site identifies AtoM as the application managing the database and describes the service as a place to search and browse member archives’ guides together. The populated portal offers browsing across archival institutions, descriptions, creators, functions, subjects, places and digital objects, with examples including parish registers and diocesan records. MELTE states that the service receives support from Hungary’s National Cultural Fund. This is an operational adoption by a consortium; the available documentation does not specify when the current platform began or what systems member archives used previously.
