ISO 15707 International Standard Musical Work Code (ISWC) International Standard Musical Work Code (ISWC) is a unique identifier for musical works, similar to ISBN. Its primary purpose is in collecting society administration, and to clearly identify works in legal contracts. It would also be useful in library cataloging. Due to the fact that a musical work can have multiple authors, it is inevitable that, on rare occasions, a duplicate ISWC might exist and might not be detected immediately. Because of the existing business practices among collecting societies, it is not possible to simply declare an ISWC as obsolete. In such cases, as soon as they are identified, the system will deal with duplicate registrations by linking such registration records in the ISWC database.

ISWC

public ISWC()

Method Detail

type

public String type()

Description copied from interface: StandardNumber

Return the type of this standard number

Specified by:

type in interface StandardNumber

Returns:

the type

compareTo

public int compareTo(ISWC iswc)

Specified by:

compareTo in interface Comparable<ISWC>

set

public ISWC set(CharSequence value)

Description copied from interface: StandardNumber

Set the input value of this standard number. The input must be normalized and verified before being accepted as valid.

Specified by:

set in interface StandardNumber

Parameters:

value - the raw input value

Returns:

this standard number

createChecksum

public ISWC createChecksum(boolean createChecksum)

Description copied from interface: StandardNumber

Indicate that a correct check sum should be computed.

Specified by:

createChecksum in interface StandardNumber

Returns:

this standard number

normalize

public ISWC normalize()

Description copied from interface: StandardNumber

Normalize the value by removing all unwanted characters or replacing characters with the ones required for verification.

Specified by:

normalize in interface StandardNumber

Returns:

this standard number

isValid

public boolean isValid()

Description copied from interface: StandardNumber

Check this number for validity.

Specified by:

isValid in interface StandardNumber

Returns:

true if valid, false otherwise

verify

public ISWC verify()
            throws NumberFormatException

Description copied from interface: StandardNumber

Verify the number.

Specified by:

verify in interface StandardNumber

Returns:

this standard number if verification was successful

Throws:

NumberFormatException - if verification failed

normalizedValue

public String normalizedValue()

Description copied from interface: StandardNumber

Return normalized value of this standard number. In most cases, this is also the canonical form of the standard number. This is a representation without unneccessary characters, useful for computation purposes, like comparing for equivalence.

Specified by:

normalizedValue in interface StandardNumber

Returns:

the normalized value

format

public String format()

Description copied from interface: StandardNumber

Return a formatted value of this standard number This is best for human-readable representation, but is not necessarily a format for computation.

Specified by:

format in interface StandardNumber

Returns:

a formatted value

reset

public ISWC reset()

Specified by:

reset in interface StandardNumber
