Information systems for e-so y must provide dierent kind of with

traditional systemsin addition to requirements.Katayama[1℄

one of them as ity, h is a y that information systems

answer any questions b a a system developer or a of

government tability aboutnotonlytheanswerofthequestion,

but thepro ofreasoning hgivestheanswer.Developmentpro for

traditional systemsmainly fo onhowto satisfy its requirements,

so we need a new pro for sp , build or reuse software systems h

is of not only the result but the and reasonings Our goalis to

provide basisand to propose an for informationsystems

with tability

2 Component T hnologies

but theyare nowalso hnologies in y, dependability and

world-wide y Many hanisms are proposed and used for software reuse,
