ISO 21047 International Standard Text Code (ISTC) The International Standard Text Code (ISTC) is a numbering system for the unique identification of text-based works; the term “work” can refer to any content appearing in conventional printed books, audio-books, static e-books or enhanced digital books, as well as content which might appear in a newspaper or journal. The ISTC provides sales analysis systems, retail websites, library catalogs and other bibliographic systems with a method of automatically linking together publications of the “same content” and/or “related content”, thus improving discoverability of products and efficiencies. An ISTC number is the link between a user’s search for a piece of content and the ultimate sale or loan of a publication. The standard was formally published in March 2009 Checksum algorithm is ISO 7064 MOD 16/3

ISTC	normalize() Normalize the value by removing all unwanted characters or replacing characters with the ones required for verification.
String	normalizedValue() Return normalized value of this standard number.
ISTC	reset()
ISTC	set(CharSequence value) Set the input value of this standard number.
String	type() Return the type of this standard number

ISTC

public ISTC()

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(ISTC istc)

Specified by:

compareTo in interface Comparable<ISTC>

set

public ISTC 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 ISTC createChecksum(boolean createWithChecksum)

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 ISTC 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 ISTC 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 ISTC reset()

Specified by:

reset in interface StandardNumber
