-# Worblehat
-
-Worblehat er PVVs biblioteksystem.
-
-- [FAQ](./wiki/faq.md)
-
-## Foreløpige planer
-
-### Database
-
-Vi skal ha en PostgreSQL-database, med designet gitt i [`db.txt`](./db.txt). Er designet feil, vennligst rett.
-
-### Informasjonsinnhenting
-
-Tenkte å bruke protokollen Z39.50 mot BIBSYS. Vi skal ha et kommandolinjegrensesnitt for å legge inn bøker. Vi skal kjøpe en strekkodeleser for å blippe inn ISBN-nummeret, og systemet skal slå opp dette i BIBSYS. Resultatene skal returneres, og vi skal velge riktig bok, som så skal bli lagt inn i databasen. Dette bør det være mulig å gjøre både brukervennlig for registrering av en bok, og raskt ved registrering av flere hundre bøker.
-
-### Utspørring
-
-Kommandolinjegrensesnitt, IRC-bot og/eller web-grensesnitt for å spørre databasen. IRC-boten skal ha et logikklag mellom seg selv og databasen, for å slippe så mye logikk internt. Dette laget kan også de andre grensesnittene bruke.

-Hei,
-
-i går startet vi opp med planleggingen av det nye biblioteksystemet. Det
-har fått navnet Worblehat, og mailinglista worblehat@pvv.ntnu.no er
-opprettet. Siden det fremdeles ikke er så mange som har meldt seg på
-der, spammer jeg denne også til aktive.
-
-Det er dessuten sendt mail til drift, om å legge oss ut på dev.
-
-Vi har laget et foreløpig design av både systemet og databasen. Disse er
-foreløpig å finne på http://www.pvv.ntnu.no/~tirilane/worblehat.
-Rettelser og forbedringer mottas med takk. Det hadde vært spesielt fint
-om noen med peiling på databaser kunne gå gjennom worblehat-db.dia og
-fikse. Og det hadde vært enda bedre om noen med peiling på databaser
-kunne implementere databasen, og legge inn alle de magiske triksene for
-å få til til å gå raskt.
-
-Ellers er designet ganske enkelt. Vi trenger en database, og noen
-klienter. Vi trenger blant annet en for registrering av nye bøker. Den
-skal ha to modus:
-1) Registrering av en bok
-2) Registrering av mange bøker
-Vi tenkte at 1) kunne være sånn fin og brukervennlig, mens 2) skal gå
-raskt for mange bøker. Gjerne slik:
-Blippe bok, klienten plukker opp ISBN-nummeret, spør ISBNdb.com, og
-registrerer boka i databasen om den ble funnet. Ble den ikke funnet, må
-den på en eller annen måte si fra, slik at vi kan ta boka manuelt. Dette
-kan løses ved å samle opp ISBN-nummeret, men siden det å manuelt lete
-etter bøker med et gitt ISBN-nummer ikke akkurat er lett, hadde det nok
-vært bedre om den stoppet opp eller noe.
-
-Dessuten trenger vi noe for å spørre databasen. Her tenkte vi CHI,
-IRC-bot og noe web-basert. Strengt tatt trenger vi bare en, og da bør
-kanskje CLI ha hovedprioritet.
-
-For at en eventuell IRC-bot ikke skal gjøre for mye arbeid, tenkte vi å
-ha et lag mellom boten og databasen. Denne skal implementere
-søke-funksjonene, som boten bare trenger å kalle. De andre (CLI og web)
-står også fritt til å benytte seg av dette. Det blir opp til de som
-implementerer. Fordelen er mindre duplisering av kode. Ulempen er at da
-må alle skrives i samme språk. Men opp til implementørene.
-
-En ting vi ikke har bestemt, er om plasseringen i hylla skal baseres på
-Deweys system eller UDC. Fordelen med Dewey er at nummeret kan hentes
-ned fra ISBNdb.com sammen med resten av informasjonene. Fordelen med UDC
-er at det er mye mer spesialisert, hvilket kan være en stor fordel når
-vi har så mange bøker om et såpass smalt felt. Dessuten bruker Teknisk
-hovedbibliotek UDC. Hva synes man?
-http://en.wikipedia.org/wiki/Universal_Decimal_Classification
-http://en.wikipedia.org/wiki/Dewey_Decimal_Classification
-
-Og hvem har lyst til å fikse hva? Noen frivillige?
