Digitalis adatok archivalasa

[Király Péter]

Az alabbiakban az elektronikus adatok archivalasarol folyo levelvaltas forditasa kovetkezik. A kerdeseket Gregor Thomson tette fel a tortenettudomany digitalizaciojaval foglalkozo levelezolistara (history-digitisation), amire Mark Conrad, a (U.S.) National Archives Center for Electronic Records igazgatoja valaszolt.

Azt kertek tolem, hogy tudjam meg, hogy jelenleg mi szamit orthodox modszernek a nagy terjedelmu digitalis adatok archivalasa teruleten.

**Nem vagyok biztos abban, hogy ezen a teruleten letezik-e egyaltalan orthodox modszernek nevezheto dolog.

Ha Onok erintettek digitalizacios programokban vagy digitalis informaciok archivalasaban, erdekelne, hogy milyen formatumot vagy adathordozot hasznalnak a digitalis forrasok tarolasara, valamint milyen eszkozt hasznalnak, milyen elveket kovetnek 

**Az amerikai Elektronikus Iratok Nemzeti Leveltari Kozpontja (U.S. National Archives Center for Electronic Records) jelenleg 3480-as osztalyu szalagokat (3480-class cartridges) hasznal a gyujtemeny tarolasara. A technologiai valtozasokkal az adathordozo/formatum is valtozik. Az iratokat legalabb tiz evente atirjak az ujabb adathordozokra. Ezeket szigoruan meghatarozott homersekleti es paratartalom viszonyok mellett taroljak, valamint evente ellenorzik az adatvaszteseget.

Erdekelne az is, hogy milyen kihivasokkal es lehetosegekkel szamolnak.

** A Nemzeti Torteneti Kiadvanyok es Iratok Bizottsaga (National Historical Publications and Records Commission - NHPRC) kulonfele kutatasi es fejlesztesi projekteket tamogat ezen a teruleten. Az NHPRC felalitott egy, az elektronikus iratokra vonatkozokutatasi utemtervet is. Az utemterv es a Bizottsag altal alapitott, az utemtervet megcelzo projektek megtalalhatoak a websitunkon: http://www.nara.gov/nhprc/electron.html. Ebbol kepet kaphat a jelen kihivasairol.

Azt javasoltak, hogy mikrofilmet hasznaljunk az adatok archivalasara - es amikor a technologia tulhaladotta teszi a regi eletronikus masolatot ebbol keszitsunk ujat. Errol is szeretnek hallani valamit, ha valaki esetleg hasznal ilyen rendszert.

** Az elozo bekezdes alapjan feltetelezem, hogy Onoknel az adatok nagy resze digitalis kep. Nem tudom ugyanis hogy lehetne mikrofolmre venni egy adatbazist, vagy egy mozgokepes videot. A mikrofilm pusztan a kepek szamara lehet esszeru hosszu tavu adathordozo. Bizonyos, hogy ezzel kezelni lehet szamos, a szoftver/hardver elavulasaval jaro problemat. A Kodaknak (es masoknak is) vannak olyan eszkozeik, amelyek a digitalis kep keszitesevel egy idoben mikrofilmet is keszitenek. Fontos ugyanakkor annak biztositasa, hogy a mikrofilm archivalasra alkalmas minosegu legyen, feleljen meg az erre vonatkozo szabvanyoknak.

**Anne Kenney, Steve Chapman, Paul Conway es masok sokat irtak a jo minosegu kepek kesziteserol. A Tarsadalomtudomanyi Informacios Szolgalat es -Technologia Nemzetkozi Szovetsege (International Association for Social Science Information Service and Technology - IASSIST) olyan tehetseges es alkalmas emberek csoportja, akiknek nagy tapasztalatuk van a hosszu tavu megorzes es adathozzaferes gyakorlataban.
