Problemi "materiali" per REICAT e MARC 21. Come registrare le designazioni di materiale "Tangible" problems encountered when working with REICAT and MARC 21. Recording General and Specific Material Designations

Abstract

I problemi che sorgono nella registrazione delle designazioni generiche e specifiche del materiale di REICAT in alcuni campi di MARC 21 sono analizzate attraverso mappature che evidenziano difficoltà derivanti dalle diverse concezioni sottese ai due strumenti. La prima mappatura confronta la DGM con il Leader/06, il Tipo di registrazione. Essa mostra il modo in cui alcuni tipi di record previsti in MARC 21 restino senza una corrispondenza. Dalla mappatura tra il Leader/06 e la DGM deriva anche la mappatura con i tipi di materiale del campo 008. Le maggiori difformità si riscontrano in questo caso per la DGM "Documenti elettronici", dato che una risorsa elettronica di natura principalmente testuale riceve come Tipo di registrazione (Leader/06) il codice a, vale a dire Materiale testuale. La terza mappatura si occupa sempre di DGM, in rapporto con il campo 007 di MARC21. In questo caso, tre elementi MARC 21 mancano di corrispondenza: f - Materiale tattile, o - Kit e r - Immagine di telerilevamento. Di recente, il MARC 21 è stato aggiornato per venire incontro alle novità introdotte da Resource Description and Access (RDA). Tuttavia, anche in questo caso la corrispondenza tra i rispettivi elementi non è del tutto univoca, e si riscontrano degli slittamenti tra MARC21, RDA e REICAT. Infine, è analizzato il rapporto tra MARC21 e DSM. Quest'ultima può essere mappata con la "Specific material designation" del "Physical Description Fixed Field - General Information", ma presenta problemi legati al diverso concetto di "testo" presente in REAICAT e MARC21.Problems in recording generic and specific designations of REICAT in some of the fields of MARC21 are analyzed through mappings highlighting some difficulties of the two tools. The first mapping compares GMD (General Material Designation) with Leader/06 (Type of record); it shows that some records in MARC21 have no correspondence in REICAT. From the mapping GMD/ Leader/06 it derives the mapping with materials of the field 8. The main differences in this case appear for GMD "Electronic resources", since a textual electronic resource receives as recording (Leader/06) the a code, "Textual document". The third mapping is related to GMD as well with relation to MARC21 Leader/07: Tactile material, Kit, and Remote-sensing image lack of correspondence. MARC21 has been recently updated to meet the needs of RDA (Resource Description and Access), however the elements correspondence is not univocal, with shifts between MARC21, RDA and REICAT. At the end, the author analyzes the relationship between MARC21 and SMD (Specific Material Designation), that can be mapped as "Specific material designation" of the "Physical Description Fixed Field - General Information", even though presenting some problems related to the different idea of "text" in REICAT and MARC21.
