-ISBN (books) and ISSN (serials)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This directory contains definitions for a couple of PostgreSQL
-external types, for a couple of international-standard namespaces:
-ISBN (books) and ISSN (serials). Rather than just using a char()
-member of the appropriate length, I wanted my database to include
-the validity-checking that both these numbering systems were designed
-to encompass. A little bit of research revealed the formulae
-for computing the check digits, and I also included some validity
-constraints on the number of hyphens.
-
-The internal representation of these types is intended to be
-compatible with `char16', in the (perhaps vain) hope that
-this will make it possible to create indices of these types
-using char16_ops.
-
-These are based on Tom Ivar Helbekkmo's IP address type definition,
-from which I have copied the entire form of the implementation.

+
+Copyright Germán Méndez Bravo (Kronuz), 2004 - 2006
+This module is released under the same BSD license as the rest of PostgreSQL.
+
+The information to implement this module was collected through
+several sites, including:
+ http://www.isbn-international.org/
+ http://www.issn.org/
+ http://www.ismn-international.org/
+ http://www.wikipedia.org/
+the prefixes used for hyphenation where also compiled from:
+ http://www.gs1.org/productssolutions/idkeys/support/prefix_list.html
+ http://www.isbn-international.org/en/identifiers.html
+ http://www.ismn-international.org/ranges.html
+Care was taken during the creation of the algorithms and they
+were meticulously verified against the suggested algorithms
+in the official ISBN, ISMN, ISSN User Manuals.

+THIS MODULE IS PROVIDED "AS IS" AND WITHOUT ANY WARRANTY

+
+Content of the Module
+-------------------------------------------------
+
+This directory contains definitions for a few PostgreSQL
+data types, for the following international-standard namespaces:
+EAN13, UPC, ISBN (books), ISMN (music), and ISSN (serials). This module
+is inspired by Garrett A. Wollman's isbn_issn code.
+
+I wanted the database to fully validate numbers and also to use the
+upcoming ISBN-13 and the EAN13 standards, as well as to have it
+automatically doing hyphenations for ISBN numbers.
+
+This new module validates, and automatically adds the correct
+hyphenations to the numbers. Also, it supports the new ISBN-13
+numbers to be used starting in January 2007.
+
+Premises:
+1. ISBN13, ISMN13, ISSN13 numbers are all EAN13 numbers
+2. EAN13 numbers aren't always ISBN13, ISMN13 or ISSN13 (some are)
+3. some ISBN13 numbers can be displayed as ISBN
+4. some ISMN13 numbers can be displayed as ISMN
+5. some ISSN13 numbers can be displayed as ISSN
+6. all UPC, ISBN, ISMN and ISSN can be represented as EAN13 numbers
+
+Note: All types are internally represented as 64 bit integers,
+ and internally all are consistently interchangeable.
+
+We have the following data types:
+
++ EAN13 for European Article Numbers.
+ This type will always show the EAN13-display format.
+ Te output function for this is -> ean13_out()
+
++ ISBN13 for International Standard Book Numbers to be displayed in
+ the new EAN13-display format.
++ ISMN13 for International Standard Music Numbers to be displayed in
+ the new EAN13-display format.
++ ISSN13 for International Standard Serial Numbers to be displayed
+ in the new EAN13-display format.
+ These types will always display the long version of the ISxN (EAN13)
+ The output function to do this is -> ean13_out()
+ * The need for these types is just for displaying in different
+ ways the same data:
+ ISBN13 is actually the same as ISBN, ISMN13=ISMN and ISSN13=ISSN.
+
++ ISBN for International Standard Book Numbers to be displayed in
+ the current short-display format.
++ ISMN for International Standard Music Numbers to be displayed in
+ the current short-display format.
++ ISSN for International Standard Serial Numbers to be displayed
+ in the current short-display format.
+ These types will display the short version of the ISxN (ISxN 10)
+ whenever it's possible, and it will show ISxN 13 when it's
+ impossible to show the short version.
+ The output function to do this is -> isn_out()
+
++ UPC for Universal Product Codes.
+ UPC numbers are a subset of the EAN13 numbers (they are basically
+ EAN13 without the first '0' digit.)
+ The output function to do this is also -> isn_out()
+
+We have the following input functions:
++ To take a string and return an EAN13 -> ean13_in()
++ To take a string and return valid ISBN or ISBN13 numbers -> isbn_in()
++ To take a string and return valid ISMN or ISMN13 numbers -> ismn_in()
++ To take a string and return valid ISSN or ISSN13 numbers -> issn_in()
++ To take a string and return an UPC codes -> upc_in()
+
+We are able to cast from:
++ ISBN13 -> EAN13
++ ISMN13 -> EAN13
++ ISSN13 -> EAN13
+
++ ISBN -> EAN13
++ ISMN -> EAN13
++ ISSN -> EAN13
++ UPC -> EAN13
+
++ ISBN <-> ISBN13
++ ISMN <-> ISMN13
++ ISSN <-> ISSN13
+
+We have two operator classes (for btree and for hash) so each data type
+can be indexed for faster access.
+
+The C API is implemented as:
+extern Datum isn_out(PG_FUNCTION_ARGS);
+extern Datum ean13_out(PG_FUNCTION_ARGS);
+extern Datum ean13_in(PG_FUNCTION_ARGS);
+extern Datum isbn_in(PG_FUNCTION_ARGS);
+extern Datum ismn_in(PG_FUNCTION_ARGS);
+extern Datum issn_in(PG_FUNCTION_ARGS);
+extern Datum upc_in(PG_FUNCTION_ARGS);
+
+On success:
++ isn_out() takes any of our types and returns a string containing
+ the shortes possible representation of the number.
+
++ ean13_out() takes any of our types and returns the
+ EAN13 (long) representation of the number.
+
++ ean13_in() takes a string and return a EAN13. Which, as stated in (2)
+ could or could not be any of our types, but it certainly is an EAN13
+ number. Only if the string is a valid EAN13 number, otherwise it fails.
+
++ isbn_in() takes a string and return an ISBN/ISBN13. Only if the string
+ is really a ISBN/ISBN13, otherwise it fails.
+
++ ismn_in() takes a string and return an ISMN/ISMN13. Only if the string
+ is really a ISMN/ISMN13, otherwise it fails.
+
++ issn_in() takes a string and return an ISSN/ISSN13. Only if the string
+ is really a ISSN/ISSN13, otherwise it fails.
+
++ upc_in() takes a string and return an UPC. Only if the string is
+ really a UPC, otherwise it fails.
+
+(on failure, the functions 'ereport' the error)
+
+Testing/Playing Functions
+-------------------------------------------------
+isn_weak(boolean) - Sets the weak input mode.
+This function is intended for testing use only!
+isn_weak() gets the current status of the weak mode.
+
+"Weak" mode is used to be able to insert "invalid" data to a table.
+"Invalid" as in the check digit being wrong, not missing numbers.
+
+Why would you want to use the weak mode? well, it could be that
+you have a huge collection of ISBN numbers, and that there are so many of
+them that for weird reasons some have the wrong check digit (perhaps the
+numbers where scanned from a printed list and the OCR got the numbers wrong,
+perhaps the numbers were manually captured... who knows.) Anyway, the thing
+is you might want to clean the mess up, but you still want to be able to have
+all the numbers in your database and maybe use an external tool to access
+the invalid numbers in the database so you can verify the information and
+validate it more easily; as selecting all the invalid numbers in the table.
+
+When you insert invalid numbers in a table using the weak mode, the number
+will be inserted with the corrected check digit, but it will be flagged
+with an exclamation mark ('!') at the end (i.e. 0-11-000322-5!)
+
+You can also force the insertion of invalid numbers even not in the weak mode,
+appending the '!' character at the end of the number.
+
+To work with invalid numbers, you can use two functions:
+ + make_valid(), which validates an invalid number (deleting the invalid flag)
+ + is_valid(), which checks for the invalid flag presence.
+
+Examples of Use
+-------------------------------------------------
+--Using the types directly:
+ select isbn('978-0-393-04002-9');
+ select isbn13('0901690546');
+ select issn('1436-4522');
+
+--Casting types:
+-- note that you can't cast from ean13 to other type, thus the following
+-- will NOT work: select upc(ean13('0220356483481'));
+ select ean13(upc('220356483481'));
+
+--Create a table with a single column to hold ISBN numbers:
+ create table test ( id isbn );
+ insert into test values('9780393040029');
+
+--Automatically calculating check digits (observe the '?'):
+ insert into test values('220500896?');
+ insert into test values('978055215372?');
+
+ select issn('3251231?');
+ select ismn('979047213542?');
+
+--Using the weak mode:
+ select isn_weak(true);
+ insert into test values('978-0-11-000533-4');
+ insert into test values('9780141219307');
+ insert into test values('2-205-00876-X');
+ select isn_weak(false);
+
+ select id from test where not is_valid(id);
+ update test set id=make_valid(id) where id = '2-205-00876-X!';
+
+ select * from test;
+
+ select isbn13(id) from test;
